大棚辣椒经常会出现烂果现象,其发生原因很多,有的是棚内温湿度所造成,有的是病害所造成,在生产中应视情况采取相应的措施。1.控制棚内温湿度。加强通风,减少结露,夜间注意盖帘增温。使白天棚内温度控制在23℃~27℃,夜间温度控制在16℃~20℃,空气相对湿度控制在70%~80%。2.化学药剂防治病害。造成辣椒烂果的病害主要有疫病、软腐病和灰霉病。①疫病:发病初期喷洒50%甲霜铜600倍液,或75%代森锰锌 Greenhouse peppers often rotten fruit phenomenon, which occurred for many reasons, some are caused by shed temperature and humidity, and some diseases caused by the production should be taken as appropriate measures. 1. Control shed temperature and humidity. Strengthen the ventilation, reduce condensation, cover curtain warming at night. The daytime temperature control in the 23 ℃ ~ 27 ℃, night temperature control at 16 ℃ ~ 20 ℃, air relative humidity control at 70% to 80%. 2. Chemical control disease. Diseases that cause rotten chili are mainly blight, soft rot and gray mold. ① disease: the early onset of spraying 50% a cream of copper 600 times, or 75% mancozeb
