1) Gibberellin. When eggplant blooms, spraying leaves with 10-50 mg/L gibberellin once can promote fruit setting and increase yield; At the flowering stage of tomato, spraying 10-50 mg/L gibberellin once on the flower can promote fruit setting and prevent empty fruit.

2) Chloramphenicol and oxytocin. In the 3-4 leaf stage of tomato seedlings, spraying 500 -- 600 mg/L of chlormequat can cultivate dwarf and strong seedlings and improve the rate of transplanting slow seedlings; And 0.3% chlormequat can be used for seed coating, which has a certain effect on the cultivation of strong tomato seedlings and the increase of stress resistance; At the seedling stage, after planting and the initial flowering stage of tomato, 100 -- 150mg/L of auxin can be sprayed on the whole plant, which can make the plant moderately dwarf, increase roots, promote early flowering and fruit, and improve cold resistance.

3) Yiyiling. In the budding and flowering stage of tomato, spraying 20-30 mg/L Zengyin twice can prevent flower and fruit falling.

4) Anti-colourin. Dipping or spraying 20-30 mg/L anti-coloughing agent into the flower or spraying at the full flowering stage of tomato has obvious effects on fruit preservation and yield increase, especially in the 3-5 flowers of inflorescence, the yield increase is obvious; Spraying 20 - 30 mg/L of anti-falling element at the flowering stage of eggplant can prevent flower falling and increase early yield; Spraying 20-30 mg/L of anti-collapsin at the initial flowering stage of pepper can protect flowers and fruits and increase yield.

5)2，4-D。 Dipping or spraying 2,4-D20-30mg/L of tomato in flower can improve the fruit setting rate of tomato; The yield of eggplant can be increased by spraying or dipping flowers with 2,4-D25-50mg/L at flowering stage.

6) Naphthoic acid. At the turn of spring and summer, when tomatoes are prone to fall in low temperature or high temperature season, 10-25 mg/L naphthoic acid can be used to spray flowers to prevent falling, and it is strictly prohibited to spray or spray on the growth point again; At the flowering stage of pepper, spraying with 50mg/L NAA can effectively increase the yield of pepper; Methyl naphthylacetate is sprayed on dry soil and paper scraps to make medicinal soil, and then mixed with potatoes. 200-300mg of 1kg potatoes can inhibit the sprouting of potato chips during storage.

7) Ethrel. In order to make the tomato come into market early, when the tomato fruit is grown and white with yellow, 1000-2000mg/L ethephon can be sprayed on the plant or smeared on the tomato fruit, which can make the fruit mature early, or the green tomato can be picked off, soaked with 800-1000mg/L solution for about 1 min (min), and then taken out and placed at 20-25 ℃, which also has ripening effect.

8) Than long. When the tomato leaves 1 and 4, spray 2500mg/L for one time respectively to inhibit the vegetative growth of tomato and promote fruit setting; At the early flowering stage of potato, spraying 3000 mg/L of water on the plant once can inhibit stem elongation and increase tuber growth.

9) Green vegetable. At 14-21 days (days) before the potato harvest, 2000-3000 mg/L of cyanogen was sprayed on dry soil and paper scraps to make medicinal soil, and mixed with potato could inhibit the sprouting of potato chips during storage.

10) Sodium nitrophenol. Potato tubers can be soaked in 6000 times of sodium nitrophenolate solution for 5 to 12 h (h), and then cut and seeded; Spraying 6000 times of sodium nitrite solution 1-2 times during tomato growth and bud stage is beneficial to plant growth.

11) 5406 cytokinin. 30 days (days) after planting of eggplant, spray with 600 times of its liquid, once every 10 days (days), a total of 3 times, which can protect flowers, fruits, early ripening, and increase yield by about 30%; The tomato has been sprayed with 400-450 times of liquid since the fourth leaf, once every 10 days, a total of five times, which can protect flowers and fruits, increase yield by more than 25%, and also reduce leaf mold and mosaic; Before potato planting, soak the potato block with its 100-fold solution for 12h (h), and spray it with its 600-fold solution three times continuously during the growth period, which can increase the yield by more than 25%.
