Scientific planting. Choose resistant varieties, plant strong seedlings without pests and diseases, do not plant roots and broken leaf seedlings, reasonably close planting, and improve ventilation conditions.

Temperature and humidity management. In the flowering result stage, the ventilation should be increased. The shed temperature should be kept at 20~27 degrees during the daytime. When the night temperature is not lower than 15 degrees, it can be ventilated day and night, and good ventilation can ensure the plant growth is strong.

Fertilizer management. Do not water and topdress before fruiting, thus controlling vegetative growth and promoting reproductive growth. Phosphorus and potassium fertilizer should be added during topdressing, reduce the amount of nitrogen fertilizer, enter the flowering period and fruit setting period, the fruit will expand rapidly, and apply a large amount of nitrogen, phosphorus and potassium fertilizer. .

Control soil air humidity. The air humidity is between 55% and 65%, and the soil moisture is about 15%. The soil should be kept moist during the fruiting period.

Prevent disease. Capsicum virus disease causes plants to shrink and cannot grow in branches, which seriously affects yield. The virus disease caused by aphids should be thoroughly and earlyly prevented, and it should be eliminated in the spotting stage. It can be sprayed and treated with insecticide + new high-fat film; if the disease occurs, it should be effectively controlled with targeted drugs in time, and spray the tree general. Perform tree disinfection.
