一、发病原因1、辣椒生长喜空气干燥而土壤湿润的环境,如气温偏高(超过35℃),即影响授粉、受精,又易引起植株徒长,使植株同化功能减弱,呼吸消耗增加,引起子房枯萎,花丝干缩,致使落花落果,或遇到较长时间的阴雨天,光照不足,温度下降(低于15℃),也会影响授粉及花粉管的伸长,导致落花。2、土壤干旱,水分不足,空气蒸发量大, First, the cause of the disease 1, hi chili hi air dry and moist environment, such as the temperature is high (over 35 ℃), which affect pollination, fertilization, but also easy to cause plant growth, reducing plant assimilation, respiratory consumption, causing Ovary wilt, filament shrinkage, resulting in falling flowers, or encounter a long time on the rainy days, lack of light, temperature drop (below 15 ℃), will also affect the pollination and pollen tube elongation, resulting in falling flowers. 2, soil drought, lack of water, large amount of air evaporation,
