大棚蔬菜生长需要良好的条件,但受近期连阴雨天气的影响,各种病害发生的几率明显增强,同时,虫害迁徙大棚也加大了对棚菜生长的不利影响。因此,当前做好大棚蔬菜的病虫害防治尤为关键。病害预警灰霉病肆虐,改善棚内环境为先近期,连续阴雨寡照天气非常不利于温室大棚的放风排湿,导致棚内空气湿度过高。西北农林科技大学太白蔬菜试验示范站站长程永安说,低温、高湿和日照少的环境极容易导致灰霉病的 Vegetable growth in greenhouse requires good conditions, but by the recent rainy weather, the incidence of various diseases significantly increased, at the same time, pest migration greenhouse has also increased the adverse impact on the growth of greenhouse vegetables. Therefore, the current pest control of greenhouse vegetables is particularly crucial. Disease warning Botrytis rampant, to improve the shed environment for the first time, the continuous rainy weather is very detrimental to greenhouse ventilation, wetting, leading to shed air humidity is too high. Northwest A & F University Taibai vegetable demonstration pilot station Chengyong An said low temperature, high humidity and sunshine less environment can easily lead to gray mold
