1、 Leaf vegetables.

1. Celery

When used in celery, chlormequat can effectively inhibit the sprouting of celery, thus improving and improving the quality of celery and benefiting vegetable farmers.

Specific methods:

(1) Application method: spray.

(2) Use period: before harvest.

(3) Operation steps: celery uses chlormequat, which is sprayed with 0.4% chlormequat solution at the growth point before harvest.

2. Lettuce

The effect of chlormequat on lettuce can make the stem of lettuce strong, thus improving the quality of lettuce and increasing the yield of lettuce.

Specific methods:

(1) Application method: spray.

(2) Use period: after growth.

(3) Operation steps: When using chlormequat in lettuce, it should be selected to spray the leaves with a concentration of 350 mg/L chlormequat solution after the lettuce leaves are fully grown, once every 5-6 days, 2-3 times in total.

2、 Eggplant pepper.

1. Tomato

After the four-leaf stage, tomato seedlings raised in vegetable greenhouse will grow faster because of the higher temperature in the greenhouse. In the seedbed, the phenomenon of overgrowth will occur, resulting in high-foot seedlings. Windows are often used in production? Air and less watering and other measures to control the seedling's length, but the effect is slow. The use of chlormequat to control vegetative growth and cultivate strong seedlings has quick and good effects. Practice shows that when the tomato uses chlormequat? The plant is dwarfed, the main stem is thick, the internode is short, the leaf color is dark green, and the root system is developed, which promotes the flowering and fruiting of tomato and increases the yield.

Specific methods:

(1) Application method: pouring.

(2) Use period: before planting.

(3) Operation steps: how to apply chlormequat to tomato, and the time of watering is from the third to fourth leaf of tomato to the week before planting; The application concentration is 250-350 mg/L of chlormequat.

2. Eggplant

The eggplant with chlormequat can strengthen the plant, enhance the ability of drought resistance, cold resistance and disease resistance, and thus improve the yield of eggplant.

Specific methods:

(1) Application mode: spray.

(2) Usage period: flowering.

(3) Operation steps: chlormequat is used for eggplant, and at the flowering stage, 0.4% chlormequat solution is taken to spray the leaves.

3. Chili

The application of chlormequat to pepper can control plant growth, coordinate the relationship between vegetative growth and reproductive growth, reduce flower and fruit abscission, and increase yield.

Specific methods:

(1) Application method: spray.

(2) Use period: flower bud stage.

(3) Operation steps: For pepper with the tendency of overgrowth, spray 20 mg/L of chlormequat on the leaves at the bud stage, and spray it wet.

3、 Melon bean

1. Cucumber

Cucumber treated with chlormequat can promote reproductive growth, facilitate flowering and fruiting, improve fruit setting rate and increase yield.

Specific methods:

(1) Application method: spray the whole plant.

(2) Usage period: leaf age.

(3) Operation steps: cucumber should be sprayed at 14-15 leaves when using chlormequat, and the concentration of chlormequat should be 250 mg/L.

2. Broad bean

The effect of chlormequat on broad bean can enhance drought resistance, promote reproductive growth, improve pod setting rate and increase yield.

Specific methods:

(1) Application method: immersion.

(2) Use period: before sowing.

(3) Operation steps: broad bean uses chlormequat before sowing. Soak the seeds in the chlormequat solution with a concentration of 400 mg/L for 6 hours, and then pick them up and dry them before sowing.
