日光温室和塑料大棚等保护地(设施)生产,是在常期封闭或半封闭的环境条件下进行的,通常温度高、湿度大,容易导致各种病虫害发生严重,影响蔬菜的产能和效益。近几年推广烟雾剂防治技术,在生产中产生了很好的防治效果,得到了生产者的普遍认可。在设施条件下使用烟雾剂,不受天气影响,烟雾渗透力强,几乎无处不至。因此,治病杀虫具有事半功倍的效果。同时,该方法因具有不需要加水配对的优点,故有益于控制温棚内的空气湿度、规避病害发生条件、遏制病虫发生。 Greenhouses and plastic greenhouses and other protected areas (facilities) are usually closed or semi-closed environmental conditions, usually high temperature and humidity, easily lead to a variety of pests and diseases seriously affect the productivity and effectiveness of vegetables. In recent years, the promotion of aerosol prevention and control technology has produced good control effects in production and has been generally recognized by producers. Use aerosol under the conditions of the facility, not affected by the weather, strong smoke penetration, almost everywhere. Therefore, cure insecticide with a multiplier effect. At the same time, the method has the advantage of not needing water pairing, so it is beneficial to control the air humidity in the greenhouse and to avoid the occurrence conditions of diseases and to prevent the occurrence of pests and diseases.
