Application of plant growth regulator on cotton

According to the requirements of cotton growth and development and production objectives, from the beginning of seed germination, through several actions of one or more plant growth regulators at different growth stages, targeted and systematic adjustment of the whole growth period of crops can be achieved. Utilize the compound effect of regulators to coordinate various physiological processes in the body, solve various problems in crop growth and production, and achieve multiple objectives of production.1、 MeperidiumMepivonium, or metamide, is a plant growth regulator. It can inhibit cell elongation and inhibit the biosynthesis of gibberellin. Promote the absorption of roots, stems and leaves, promote the synthesis of chlorophyll in crops, inhibit the elongation of main stems and fruit branches, make the plant compact, delay the sealing of rows, prevent flourishing, improve the ventilation and light transmission in the field, and help to enhance photosynthesis; Control the excessive growth of crops and reduce the consumption of ineffective nutrients; Enhance the root activity of crops, so as to make the roots developed, the main root increased, the lateral root increased, and improve the resistance of crops to stress, lodging, drought and waterlogging; Rationally adjust and distribute the contradiction between vegetative growth and reproductive growth, promote reproductive growth, reduce flower and fruit abscission, mature early, improve fruit quality, and increase production and income.2、 ChlormequatThe action mechanism of this product is to inhibit the biosynthesis of gibberellin in the plant, and the action site is to inhibit the production of kaurene, resulting in the inhibition of endogenous gibberellin biosynthesis. It is an antagonist of gibberellin. Its physiological function is to control plant growth, resist lodging, enhance photosynthesis and improve stress resistance. Its physiological function is to control plant growth, resist lodging, enhance photosynthesis, improve stress resistance, improve quality, and increase yield, which can effectively regulate the growth of cotton.3、 Naphthylacetic acidThis product is a plant production regulator. It is used for cotton and can be absorbed internally. It has the functions of protecting flowers and fruits, improving fruit setting rate, promoting fruit hypertrophy and early ripening, and has a certain effect of controlling cotton growth and increasing yield. It is the main ingredient of rooting powder on the market.4、 Indobutyric acidThis product is a plant endogenous auxin, which can enter the plant body through leaves, tender epidermis and seeds, and be transported to the functional part with the nutrient flow. It can induce the differentiation of plant root primordia, rapidly open roots, accelerate root growth and development, greatly increase the number of capillary roots and the length of lateral roots, which is conducive to the formation of a large and strong plant root group, shorten the days of plant transplanting and turning green, and significantly improve the survival rate and stress resistance of transplanting; Promote tillering and strong seedlings; Promote root regeneration, strengthen plants, increase yield and improve quality.5、 Gibberellic acidThis product is a plant growth regulator. Endogenous gibberellin is widely present in plants, which is one of the important hormones to promote plant growth and development, and an antagonist of growth inhibitors such as paclobutrazol and chlormequat. The drug can promote cell, stem elongation, leaf expansion, parthenocarpy, fruit growth, break seed dormancy, change the ratio of female and male flowers, affect flowering time, and reduce flower and fruit abscission. When exogenous gibberellin is introduced into plants, it has the same physiological function as endogenous gibberellin. Gibberellin mainly enters the plant through leaves, twigs, flowers, seeds or fruits, and then transmits to the active parts for action. It can regulate the growth and increase yield of cotton.6、 ProchlorazThis product can regulate and promote cotton. It can increase the content of chlorophyll, protein and nucleic acid in the plant; Increase the photosynthetic rate and the activity of peroxidase and nitrate reductase; Improve the metabolism of carbon and nitrogen in the plant, enhance the absorption of water and fertilizer by the plant, and adjust the balance of water in the plant, thus improving the drought and cold resistance of the plant.7、 EthephonThis product is a growth regulator to promote plant maturity. After ethephon enters the plant body, it will release ethylene due to the PH size of plant tissue, promoting maturity, inhibiting elongation growth, promoting organ abscission, inducing flower bud differentiation, promoting germination, and promoting adventitious roots.It is very stable in acid medium, but above pH4, it will decompose and release ethylene. Ethyl chloride enters the plant body through the leaves, bark, fruit or seeds of the plant, and then transmits it to the functional parts, and then releases Ethyl chloride, which can play the physiological functions of the endogenous hormone Ethyl chloride, such as promoting the maturity of cotton and the shedding of leaves, dwarfing the plant, changing the ratio of male and female flowers, and promoting the early opening of cotton bolls.

Explain in depth the ten elements that affect fruit expansion!

The first element that can expand fruit is complex, that is, hydrogen, oxygen, H, OAs we all know, these two often synthesize water, which is an indispensable part of fruit expansion. If the fruit is short of water when it is expanded, then the fruit expansion will be impossible to begin with. The fruit will become delicious and juicy through water enrichment. Many fruits contain a lot of water, which is also the source of the word fruit. At the same time, hydrogen and oxygen also build a variety of organic substances on the fruit, such as sugar, protein, etc, So they are two essential elements.Second element: carbon CAs we all know, organic matter is basically constructed by the formation of carbon, and the formation of sugar, protein, fiber and other substances are all structured by carbon, so the carbon supplement is of great significance to the expansion of fruit, and has a good effect on improving the flavor and sweetness of fruit. 1、 Ensure leaf quality and smooth photosynthesis. 2、 The base fertilizer is decomposed and organic fertilizer is sufficient, which is a very important source of carbon. At the same time, humic acid, amino acid polypeptide, sugar alcohol, seaweed extract, etc. are supplemented during the growth period to increase the absorption of small molecular carbon.Third element: nitrogen NMost of the time, swelling and sweetness improvement are two different concepts. The swelling fruit is generally low in sweetness, and the sweetness begins to appear in the later stage of ripening. Then, the swelling fruit needs nitrogen supplement. The structural meaning of nitrogen is to form amino acid and protein construction. If the nitrogen is insufficient, when the fruit expands, the fruit cells begin to appear incomplete cell membrane, At the same time, nitrogen is also an element for synthesizing plant growth hormone. However, when nitrogen is excessive, the fruit will grow excessively, resulting in a decline in fruit expansion. The key to fruit expansion is to master a proper amount of nitrogen.Fourth element: zincThe use of zinc can increase the content of local indoleacetic acid in plants, and the transfer ability of zinc is not strong. If it is only used on fruit, it can enhance the fruit as an active part of metabolism to scramble for nutrition and play a better role in expanding the fruit, but at this time, it must have enough organic matter as support, so as to play a better and more effective role in expanding the fruit, Otherwise, there will be a risk that the fruit will become hollow after expansion or the ability of the fruit to resist the external environment will decline. However, when the zinc is sprayed as a whole, the content of indoleacetic acid in the whole will be increased to a certain extent, and the swelling of the fruit will be significantly different. At the same time, the use of zinc can make up for the weakness of the seeds to a certain extent, especially the grapes, After using zinc, seedless grapes can improve the snatching ability of each fruit as a whole, which can obviously prevent the formation of large and small fruits.The fifth element: potassium KPotassium basically regulates the overall solubility of crops in plants, and can also regulate the relationship between metabolic source and sink. It has a conflicting effect with zinc, but potassium is the balance between regulating the source and storage of photosynthesis, which is conducive to the accumulation of photosynthetic substances into fruits, but it should be completed on the basis of the next element.Sixth element: boron BBoron is a wonderful element in many times. If there is boron deficiency, the sugar produced by photosynthesis on the leaves will not be transported from the leaves to the fruit or the root system, resulting in the lack of fruit contents, so the foundation of organic matter will play a better role.The seventh element: calcium CaAs the second messenger, calcium participates in the regulation of cell division, and the role of calcium as the basic element cannot be ignored. Calcium can stabilize the cell wall and improve the pectin adhesion between fruit cells, so that the cell wall will not disintegrate when the fruit expands, and the carbon shelf will not be scattered. At the same time, calcium plays an important role in preventing cell separation. For growth, To a certain extent, it can control the advantage of the top, and it is also good to prevent overgrowth.The eighth element: magnesium MgMany times we are unfamiliar with magnesium. However, the first function of magnesium is to form chlorophyll, but it must be combined with nitrogen, carbon and water. The increase of chlorophyll is only more effective in providing organic matter. However, the other function of magnesium is in seeds. Many crops can see a phenomenon. After the formation of seeds, magnesium deficiency will be more serious. On some seedless fruits, the degree of magnesium deficiency is much lighter than that of seedless fruits, such as seedless watermelon.As we all know, the sweetness of fruit is achieved by potassium, but the seedless watermelon has no seeds, so the transfer of magnesium to seeds is not obvious, so the lack of magnesium is not serious. However, after the seeds are formed, when the magnesium is insufficient, the leaves immediately show the phenomenon of magnesium deficiency. If it is potassium deficiency at this time, the sweetness of fruit will be significantly reduced on the seedless watermelon. There are also grapes. Seeded grapes will lack magnesium after the formation of seeds. In severe cases, the leaves will turn yellow, but their fruit is still sweet because they do not lack potassium. When magnesium is sufficient, magnesium can be transferred to multiple parts, but when magnesium is insufficient, magnesium will be limited to the formation of seeds, because seeds are the purpose of plant growth, not fruit or leaves.Why are the ninth and tenth elements mentioned together? The two elements are sulfur and phosphorus S and PPhosphorus is the main element of energy substances, mainly the formation of ATP. The running speed of phosphorus in the plant body should be active in all elements. After the formation of ATP from the leaves, it is necessary to supply the root system with energy substances to absorb nutrients and synthesize amino acids. This time will be critical. Sulfur is to improve the speed of photosynthesis in photosynthesis, and the synthesis of protein also makes the protein have enzyme activity, The enzyme activity determines the metabolic rate of the whole organism. One provides energy for the synthesis of sugar and amino acid, the other plays a great role in improving the activity of protein and enzyme, and mutual cooperation plays a better role in expansion. Without the operation of phosphorus, the plant will lose all its power, but when the phosphorus is excessive, it will lead to premature ripening of the fruit without the completion of expansion, and serious increase in fruit fiber.Phosphorus is not a quality element, but it is a necessary element for energy transfer in many times. Proper phosphorus is very important. Excessive phosphorus will fix calcium and other trace elements; After the activity of the enzyme is increased, the speed of the synthesis of organic compounds is increased, which is beneficial to the accumulation. It will be more obvious to strengthen each other through potassium and boron. However, after the application of sulfur on the base fertilizer, there is no need to supplement it in the growing season, because the compound fertilizer and water-soluble fertilizer you use generally contain sulfur.Other elements also play a great role in photosynthesis, such as iron, but they are relatively weak for swelling, mainly in the prevention of chlorosis and premature senescence of leaves, so they are not included. Many elements are indispensable, but they are interrelated in different aspects. The elements that are not mentioned do not mean that they have no effect, but they are not as direct as using the above 10 elements in expansion.However, in addition to the above 10 elements, the expansion of some crops is not enough. For example, peanut, soybean, cucumber, tomato and other crops, if molybdenum fertilizer is used, the expansion effect will be very obvious. However, molybdenum fertilizer is expensive, and few farmers are willing to invest heavily, so it has not been well promoted and applied.

Application of plant growth regulators in flowers - camellia, privet, magnolia

camelliaCamellia japonica [scientific name]Camellia japonica, also known as Camellia japonica, Naidong, Datura stramonium, etc., belongs to the Camelliaceae, evergreen shrubs or small trees, up to 3~4m high. The single flower is opposite to the leaf axil or the top of the branch. The petals are nearly round, and the varieties can have 50 to 60 double petals. The colors of the flowers are red, white, yellow and purple.onePromote seed germinationThe seed germination of Camellia scabra is very slow after sowing. Soaking the seed with 100mg/L gibberellin solution for 24h can promote the seed germination and seedling growth.twoPromote rootingNaphthyl ethyl · indole ethyl rooting powder Soak the bundled cuttings with rooting powder at a concentration of 100~300mg/L, soaking time of 2~5h, and depth of 2cm, and then cut, which can take root quickly.IBA will circumcise the selected camellia branches at the base. Without leaving the mother plant, apply 500mg/L IBA wool cream on the circumcised part, add moss to maintain the temperature, and then wrap it with plastic film to promote rooting. After rooting, cut the branches from the mother plant and insert them into the seedbed.threeControl floweringGibberellin can control the flowering of camellia varieties in the early and middle flowering period before the National Day. It can be used with 5000mg/L of gibberellin. From August 20, it can continuously drip buds for 2-3 times every 10~20 days, which can achieve satisfactory results. If certain nutrients are added to the treatment, the flower quality will be improved and the effect will be better. Different concentrations and periods can achieve different effects.PrivetLigustrum Lucidum AitIt is also known as holly, wax tree and insect tree. The plant form is evergreen large shrub or small tree.onePromote seed germinationGibberellin can break the dormancy of Ligustrum lucidum seeds. The seeds are soaked with 550mg/L gibberellin solution for 48h, and the water is changed once every 24h. Then the seeds are taken out and dried. After 3~5d, the seeds are soaked in water at 25~30 ℃ for 10~15d.twoCuttings rootingIBA generally cuts the robust and well-organized 1-2 year-old branches of Ligustrum lucidum from mid-May to early July, removes the lower leaves, and retains 3-5 pairs of upper leaves as cuttings. The rooting rate can reach 100% and the survival rate can reach more than 90% by using 500mg/L IBA to shake and quickly dip the base of cuttings before supporting.When the rooting powder (ABT) of indole and naphthalene was used for underpinning, the rooting powder solution of 100mg/LABT was used to soak the base of cuttings for 0.5~1h, and the immersion depth was 1~2cm, which could significantly improve the survival rate of cuttings.threeDwarf flower seedlingsAfter 7~14 days or pruning of the spring buds of Ligustrum lucidum in Japan, butyrylhydrazide can be sprayed on the leaves with 2500-5000 mg/L 40% butyrylhydrazide solution, which can inhibit plant elongation, control the growth of lateral buds, and improve plant type.When the axillary buds of Ligustrum lucidum begin to grow in spring, or after the first manual pruning, spray the whole plant with 1000~2500mg/L bud inhibiting pill solution on the leaf surface, which can control the growth of their new shoots, promote the growth of the lateral buds at the lower part of the plant, and reduce the pruning in the later summer to make the plant type dense.yulanMagnolia denudate DesronePromote seed germinationAfter soaking the seeds of Magnolia grandiflora with the mixture of 400mg/L gibberellin and 200mg/L 6-benzylaminopurine for 48h, it can effectively break the dormancy of Magnolia grandiflora and improve the germination rate of the seeds under the conditions of 50% humidity and 7-10 ℃ temperature for 56d.twoPromote rooting of cuttingsNaphthylacetic acid (sodium) solution with a concentration of 500mg/L was quickly dipped for 15s before cutting to promote rooting.threePromote layering and rootingNaphthylacetic acid (sodium) high altitude layering is a common method of propagation of Magnolia grandiflora, but the rooting rate and survival rate are often not high in practice. For this reason, after girdling, 1000mg/L of naphthylacetic acid (sodium) ethanol solution can be dipped in cotton ball to smear the girdling area to speed up rooting and improve the survival rate of transplanting.Magnolia grandiflora has many roots and tillers, which can be propagated by layering. Applying 50mg/L naphthoic acid (sodium) to the girdling part can shorten the seedling period.fourImprove survival rateWhen NAA is used for cutting Magnolia grandiflora, the cutting propagation should be carried out in the north from June to July. The survival rate of the young tree's branches in the year is higher. The cutting is generally made of sand bed, shaded above, and sprayed with water every day for heat preservation. Generally, it can take root in 15-25 days. Soaking the base with 50mg/L naphthoic acid for 6h can improve the rooting rate.

The corn is about to be sown. Xiao Bian recommends several methods of using growth regulators on corn

plant growth regulatorPlant growth regulators can affect many physiological and biochemical processes of crops by regulating the level of plant endogenous hormones. At present, they have become an important part of the new agricultural technology of high yield, stable yield and efficiency in crop production in China, and play a pivotal role in maize production.The application of plant growth regulators in maize can not only promote germination and cultivate strong seedlings, but also promote the filling of maize seed, and improve the quality of maize while increasing the yield. Some growth regulators have the function of increasing yield and improving quality, and the application time is generally in the late stage of maize growth.The editor has sorted out some growth regulators that can be applied in the growth period of corn and the effects they can bring for your reference・ I. Prevent maize from lodging and control its prosperityethephon According to the test report, the application of ethephon in maize can promote the root development, play a role in dwarfing and strengthening the stem, enhance the field ventilation and light, and promote early maturity. Spraying 800-1000mg/L solution after jointing and before heading can play a role in dwarfing and increasing yield.Attention should be paid to the use: strictly control the use concentration. If the use concentration is too high, it will cause excessive inhibition of stem growth and affect the yield; Grasp the use period to prevent early or late application; The spray shall be even to prevent uneven application from causing irregular growth.ChlormequatDilute 50% aqueous solution by 80-100 times, immerse seeds by submerging seeds, and sow after drying in the shade. The plant is short and strong, the root system is developed, the ear position is low, there is no bald tip, the ear is large and the grain is full, and the yield is significant. Using 0.2-0.3% liquid medicine at seedling stage and spraying 50kg per mu can play the role of crouching seedlings, resist saline-alkali and drought, and increase yield by about 20%. Using 1000-3000ppm/L liquid medicine, spraying 30-50kg/mu liquid medicine on the leaves 3-5 days before jointing, the internode shortened, the ear position decreased, the lodging resistance, the leaves were short and wide, the photosynthesis increased, the bald tip decreased, the double ear rate increased, the 1000-grain weight increased, and the yield increased.● Improper variety selection, unreasonable planting density, unscientific fertilizer and water management, and late chemical control may cause maize lodging.(II) Promote early maturing and yield increase of corngibberellinAfter the female flower of corn is fertilized, when the filaments begin to scorch, spraying 50kg of 40-100mg/L gibberellin solution per mu or pouring it into the bracts (about 1mL plants) can reduce the bald tip, increase the number of grains, promote filling, and increase the weight of 1000 grains. In production, 4% gibberellin emulsifiable concentrates can be diluted 400-1000 times to obtain 40-100mg/L gibberellin solution, which can be sprayed on leaves.Attention should be paid to the use of the agent; Strictly control the use concentration; It should be applied in sunny days, and should be supplemented in case of rain within 6 hours after the application.III. Promote rooting and germinationAmine fresh fatSoak seeds at 15ppm for 6-16h, spray once at seedling stage, young spike differentiation stage and heading stage respectively. Improve the germination rate, plant robust, leaf color thick green, grain number full, bald and pointed degree shortened, grain ear number and 1000-grain weight increased, lodging resistance, prevention and control of red leaf disease, early maturity, high yield.● The application time of different growth regulators is different, the corresponding corn growth period is different, and the technical requirements for use are high. Please clarify before application.Correct understanding of plant growth regulatorsIn the process of maize planting, the application of plant growth regulators to regulate and control the growth and development of maize and reduce the plant height and ear height can increase the density of maize per unit area, increase the number of ears, early maturity, stable yield and yield, and give full play to the population advantages of maize. Due to lack of understanding, farmers have many improper or mistakes in the use of plant growth regulators.Maize growth regulators can be divided into single agent and mixture. The use of single agent has certain side effects. The mixture can achieve the combination of quick and long-term effects, and is generally used more. In maize production, growth promoters, growth retardants, growth inhibitors and ethephons are mainly used, with most of them being retardants.Significant effect on improving yield, quality and economic benefitsUsing plant growth regulators to treat seeds and spraying in the middle and late stages of growth can significantly improve yield, quality and economic benefits. Soaking or dressing corn seeds with plant growth regulators is conducive to breaking the dormancy of seeds, promoting the rooting and germination of seeds, ensuring the germination rate, and the vigorous growth of corn seedlings, which can extend the growth time of corn in the field and lay the foundation for high and stable yield.Regulate the growth period of maize and enhance the ability of resistance to adversity and lodgingMaize has the characteristics of rapid growth. Applying plant growth regulators can effectively control the rapid growth of maize, inhibit the apical dominance, and make maize plant height shorter.1. Nutrition supply and growth reversal of maizeWhen the rapid growth is inhibited, the nutrient supply and growth trend of maize will reverse, and the plant height traits of maize will turn to the development of plant height shortening, stem thickening, root strengthening, and leaf thickening. The lodging resistance of maize plants will be significantly enhanced, with low empty stem rate, small bald tip, and stronger disease resistance.2. Changes of plant ear position charactersThe rapid growth of maize was inhibited, and the plant ear position characters were changed, which improved the maize pollination rate, reduced the bald tip of maize, reduced the empty plant rate, and promoted the reproductive growth, making the maize ear thick, increased the number of grains per ear, and increased the grain weight per ear. In the harvest period, the number of grains, 100-grain weight, yield and other aspects of corn have been improved to a certain extent. According to statistics, the production increase can reach 8% - 12%.3. Improve photosynthetic efficiencyThe application of growth regulators in maize can increase the leaf area of maize, shorten the functional leaf nodes, improve the photosynthetic efficiency, accelerate the synthesis of photosynthetic products and flow to the ear; It makes the ear rachis longer and thinner, the grains thicker, the 100-grain weight increased, and can mature 5 to 7 days earlier, with timely and late harvest, which is of great significance for yield increase.4. Reduce field shadingAfter applying growth regulator, the plant type of maize is compact and the field shade is reduced. After the application of growth regulators, the upper leaves of maize ear were generally lifted, the plant converged, the leaf angle became smaller, and the ventilation and light transmission conditions were improved; The leaves thicken, the color darkens, the chlorophyll content increases, the leaf function strengthens, and the photosynthesis enhances; Improve the resistance of maize, delay the senescence of maize plant, promote the growth and development of maize, and achieve the purpose of increasing yield.5. Promote the development of maize root systemThe application of growth regulators can effectively inhibit the vegetative growth of the aboveground parts of maize plants and promote the growth of maize roots. The growth of maize root system has been significantly improved, the root amount of aerial root and underground secondary root has doubled, and the root absorption area has increased by 2-3 times, ensuring the supply of nutrients, making maize grow healthily, the stem is tough, and the drought resistance and lodging resistance have been improved. In addition, the productivity of maize per plant has been improved, and the yield increase effect is obvious.6. Promote fruit ripeningProper use of growth regulators can delay the senescence of maize roots and leaves in the later stage, increase the growth time of maize, and promote fruit ripening.7. Reduce the impact of adverse weather conditionsAfter the application of growth regulator, the booting time of maize will increase, and the adverse effects of low light, low temperature and heavy rain on maize growth will be reduced.8. It can increase the planting density of cornIf growth regulators are used, the planting density of corn can be appropriately increased. The use of regulators can significantly increase the stem strength and reduce the probability of lodging the corn stem, so the density can be appropriately increased during planting.

A Complete Collection of Fertilization Techniques -- About Fertilization of Fruit Trees

Mistake 1: The closer the fertilization point is to the tree, the better.Many fruit growers believe that fertilization is far away from the tree, the root absorption is poor, and the nutrient utilization is not good. Therefore, fertilization is very close to the tree, and some are less than half a meter from the root neck, and even dig out the backbone root. As a result, the phenomenon of root injury and root burning often occurs, and the effect has always been contrary to expectations.Mistake 2: The more fertilizer, the better.Some fruit farmers do not comprehensively determine the amount of fertilizer according to the type of fertilizer, the strength of the tree, the size of the tree, the amount of yield, the soil conditions and other factors, but blindly, thinking that the more the amount of fertilizer, the better. The result is that the supply and demand of tree nutrition are unbalanced, the heavy ones burn roots and die trees, diseases and pests breed, the light ones are unbalanced in nutritional growth and reproductive growth, and only trees grow, with little or even no fruit.Mistake 3: Fertilization time is busy.Some fruit farmers apply fertilizer not according to the time when the fruit trees need fertilizer, but according to the time when the labor is busy. "When the trees need fertilizer, there is no time to apply fertilizer, and when the people are idle, the trees do not need fertilizer." What should be fertilized in spring becomes summer fertilization, and what should be fertilized in autumn becomes winter fertilization. The pre-flower fertilizer that should be applied becomes post-flower fertilizer, and the post-flower fertilizer becomes post-fruit fertilizer, which missed the better fertilizer demand period of the fruit trees, and the yield increase effect is greatly reduced.Mistake 4: The more fertilizer, the better.The autumn application of base fertilizer in orchards coincides with the autumn sowing of wheat fields. Many fruit farmers use chemical fertilizer to replace the base fertilizer at will, or use uncooked crop straw to replace farm manure and other farm manure. This has been the case for years. As a result, the orchard fertility has declined, the tree vigor has weakened, the yield has decreased, and the fruit quality has deteriorated.Five misunderstandings: underground fertilization is more important than ground fertilization.Many fruit farmers are accustomed to underground fertilization, and despise or fail to understand the role of aboveground fertilization, namely, foliar fertilizer spraying, which leads to serious physiological diseases such as yellow leaf disease, small leaf disease, fruit shrinkage disease, early defoliation disease and reduced leaf photosynthetic function.Where is the best place to fertilize fruit trees?To apply fertilizer to fruit trees, first of all, we should know that fruit trees are mainly completed by root hairs in the root system; The topdressing of fertilizer for fruit trees should be based on the edge of the crown projection or a little distance, and should not be too close to the trunk, because there are thick roots near the trunk, and there are fewer fine roots and root hairs, which is not conducive to the absorption of fertilizer.The depth of fertilizer application for fruit trees should be in accordance with the following principles: fruit trees with deep root distribution should be applied deeply, and vice versa; The decomposition of organic fertilizer is slow, but the fertilizer supply period is long, which can be applied deeply, and the mobility of chemical fertilizer is large, which can be applied shallowly; For example, for deep-rooted fruit trees such as pear trees, the depth of organic fertilizer should be 40-60 cm, while for shallow-rooted fruit trees such as plum trees, the depth of organic fertilizer should be 30-40 cm. Spraying new high-fat film after fertilization can improve fertilizer efficiency.Top dressing fertilizer for fruit trees. For closed or densely planted orchards, shallow application can be applied between rows and trees, so as not to damage or less damage the big roots, so as to give full play to fertilizer efficiency, improve fertilizer utilization rate, and achieve the purpose of increasing production and income.1. Choose fertilizer according to "appetite"Generally speaking, fruit tree fertilization is like eating, and the fertilizer maker is equivalent to a cooking master. If a certain kind of fertilizer is applied too much or too little, and the "appetite" is turned off, the tree will be in a "sub-healthy" state, such as weak or weak. Total nutrient balanced fertilization should focus on supplementing the organic matter, medium and trace elements seriously lacking in the orchard to create a good site condition for root growth. Because organic fertilizer is the "passbook" of soil, it plays an important role in fertile soil, root cultivation and improving the utilization rate of fertilizer.The organic fertilizer is better to use decomposed pure chicken manure, sheep manure, oil cake and biogas manure, followed by pig manure, cow manure and farm soil manure. When manure is short or not yet decomposed, it can also be replaced by organic bacterial manure.The fertilizer should be reasonably formulated according to the needs of different varieties of fruit trees for different nutrients. Through a large number of field experiments, the reasonable ratio of nitrogen (N), phosphorus (P2O5) and potassium (K2O) of different fruit trees was determined as follows: apple 1:0.6:1, grape 1:1.41:1.25, pear 1:0.21:1.02. It should be emphasized here that although the growth and development of apples and pears throughout the year have a "high - medium - high" demand for "nitrogen, phosphorus and potassium", the basic fertilizer applied in autumn should be applied to more than 80% of the total amount of phosphorus fertilizer throughout the year, because autumn is the peak period of root growth throughout the year, and phosphorus is the rooting nutrient, which is supplied steadily throughout the year.2. Fertilization should be done at "meal time"The same meal makes people feel comfortable. When you miss a meal, you feel tasteless. Autumn is at the peak of root growth of fruit trees throughout the year. The nutrients absorbed and synthesized by the roots are mainly used for storage, which plays an important role in budding, flowering, fruit setting and shoot growth in the coming year. Therefore, the same fertilizer applied from September to October is as valuable as gold and silver; After falling leaves and next spring, it will depreciate to the value of copper and iron.3. Fat should be fed in the mouthPeople eat by mouth, trees eat by root, and the mouth of the root is at the tip. Applying fertilizer to the concentrated distribution layer of the fruit tree's absorption root is beneficial to the root absorption. In general, 80% of the absorbing roots of fruit trees such as nuts and drupes are mainly distributed in the 10-50 cm soil layer under the vertical projection of the outer branches of the tree crown, which requires that 80% of the total amount of fertilizer should be applied in this area. Young trees and early bearing trees are better applied by circular expansion. Trees in full fruit stage can use the method of alternate application of radial ditch application and whole garden spraying.4. Borrow moisture and fertilize "don't eat dry"If the soil moisture is not good, the root system will still be unable to absorb the fertilizer. Because all kinds of chemical fertilizers applied to the soil have no life and will not move. Only when they are dissolved in water, can they be absorbed and utilized by roots and leaves. At the same time, the amount of nutrients absorbed and accumulated by fruit trees in the same year is also closely related to the transpiration pull of some aboveground branches and leaves. Taking advantage of the advantages of large transpiration pull and good moisture content of leaves in early autumn, the transpiration of leaves can absorb a large amount of water and nutrients from the ground after fertilization, and the nutrient accumulation of trees will be more. Otherwise, no matter how high the effective content of fertilizer is, it cannot be dissolved in water and has no functional leaves, fertilizer will become a piece of junk metal that is not worth looking at. This is the reason why fertilizer should not be eaten dry.

Shipida (5% calcium cyclamate) bitter gourd control the growth and promote the production with you

Bitter gourd is an annual climbing soft herb, named for its bitter taste. Bitter gourd has a quality of "not passing on your own bitterness and other things", and is known as "gentleman's dish". Because of its rich minerals, such as calcium, phosphorus, iron and various vitamins and trace elements, and its rich nutrition and varied eating methods, it is widely cultivated in the south and north of China. Common cultivation modes in China include yard planting and greenhouse planting.The Harm of Bitter MelonBalsam pear is mainly produced by lateral branches, but it should be noted that the more lateral branches sprout, the more flowering and melon will be produced. Once there are too many vines, because the vines consume too much nutrients, there will be insufficient nutrition in the reproductive growth, resulting in poor flower bud differentiation, slow growth, and the balsam pear can not sit on the melon, and the deformed melon will also become more. Poor ventilation and light transmission will also lead to the weakening of the disease resistance of balsam pear and the aggravation of the disease. Balsam pear likes strong light when it enters the flowering and melon-bearing stage. If there are too many side branches, the side branches will shade each other, and the side branches will flourish, reducing the melon sitting rate. The purpose of bitter gourd controlThe purpose of prosperity control: effectively control the growth of bitter gourd and safely control prosperity. Increase the content of chlorophyll, the leaves are dark green, without yellow leaves.
