Large amount of irrigation, flood irrigation or more rainfall, rainfall, the incidence of heavy. Droughts and floods at high temperatures can reach as high as 100% in drought conditions, mainly as a result of the outbreak of pepper blight. How to prevent this phenomenon? One is to strictly level the land, avoid the low lying water, and ridge cultivation, the plant grows in the ridge, the application of microbial fertilizer (such as biological nitrogen fixation, bio-potash, etc.) inhibit pathogenic microorganisms to stimulate the root system Grow,
