How can the fruit-setting rate of colored peppers be increased when it is low?

Methods to increase the fruit-setting rate of green peppers:

1. Strengthen fertilizer and water management after planting. In the early stage after planting, combine promotion and control to promote the growth of the green pepper root system and promote early and abundant fruit setting. "Control" is mainly achieved by controlling water. Water at planting time, and the planting water should not be too much. 5-7 days after planting, after the green peppers have recovered from transplanting, water once more with recovery water (if the planting water was applied very generously and plastic film mulching is used, the recovery water may be omitted). When ending the seedling-holding period, apply fruit-promoting fertilizer, applying 10-15 kg per mu of ammonium sulfate or urea, etc. In the early fruiting period, water once every 10-15 days, and apply fertilizer once after every other watering. New vegetable plots especially need strengthened fertilizer and water management, and watering should not be done by flooding.

2. Low temperature and weak light easily cause flower and fruit drop. In protected cultivation, attention should be paid to heat preservation to prevent nighttime temperatures from being too low, which causes flower and fruit drop. Also clean dust off the film to improve light transmittance, increase light, prevent fruit drop, and increase the fruit-setting rate.

3. Under conditions of low temperature and weak light, Baoguoning may be appropriately sprayed on flowers to promote fruit setting.

4. Reduce watering during the flowering period, and carry out fertilization and watering after fruit setting. Liu Zhenghua, Wangdu, Hebei
