First, select resistant varieties

According to the cultivation season and the occurrence of local diseases, the varieties of pepper resistant to pests and diseases should be selected according to local conditions.

Second, improve the farming system

The rotation cropping system is implemented, and cruciferous, leguminous or onion and garlic vegetables are planted for 3-5 years. When exposed to cultivation in summer, they can be used as high-stalk crops to reduce the occurrence of pests such as thrips and diseases such as epidemics. Deep trench sorghum, to prevent water accumulation, to prevent the spread of infectious diseases.

Third, fine management

Deep cultivating ridges, intensive cultivation, increase soil permeability, reduce the number of insects, and reduce the initial infestation. Timely removal of old leaves, yellow leaves, pests and leaves, and timely removal of diseased plant debris, brought out of the field to concentrate buried or destroyed.

Fourth, cultivation measures

The use of sorghum, narrow sorghum, and deep ditch cultivation can be based on the soil texture and groundwater conditions in accordance with local conditions to choose the appropriate sorghum height, generally sorghum height 20-25 cm, stern width 70-80 cm, one planting 2 lines. Covered with plastic film or straw, water retention reduces the occurrence and spread of diseases.

Fifth, fertilizer and water management

Increase the use of organic fertilizer, formula fertilization according to soil fertility. Priority will be given to the integration of fertilizer and water, drip irrigation under the membrane, and dark irrigation.

Six, environmental regulation

Under the cultivation conditions, increase the temperature difference between day and night, control the night temperature at 15°C-20°C, daytime temperature at 25°C-30°C, and control the temperature in the facility according to the suitable temperature in different growth periods to avoid the low temperature and high temperature obstacles. Encountered continuous rainy days, timely ventilation and dehumidification, delayed closure of the vent time, reduce condensation, prevent the occurrence and epidemic of the disease.
