病虫害是保护地蔬菜生产中的巨大威胁.目前保护地蔬菜病虫害防治仍以药剂防治为主,其施药方式主要是喷雾,喷雾不但费工费时,而且着药不均匀,防治效果不佳.同时,药液污染食用部分严重,有害于消费者的身体健康.再者,喷雾用大量的水,喷雾后保护地内湿度增加,有诱发和加重病虫害发生的作用.针对以上情况,利用保护地密闭的特点,在药剂剂型和施药方式上进行大胆革新,用烟剂熏烟代替药液喷雾,不但提高防效,减少污染,节省开
Pests and diseases are a great threat to the production of vegetables in protected areas. At present, the prevention and control of pests and diseases of vegetables in protected areas are still mainly based on the prevention and treatment of pesticides. The spraying modes are mainly spraying and spraying, which not only takes time and labor, but also produces inhomogeneous medicine and has poor control effects. , The liquid contamination of food is partly serious, harmful to the health of consumers.Moreover, the spray with a large amount of water, spray humidity increases after the protection of the ground, induce and aggravate the occurrence of pests and diseases.In response to the above situation, the use of protected airtight Characteristics, in the pharmaceutical dosage forms and application of bold innovation on the way, instead of using liquid smoke smoke fumes spray, not only improve control efficiency, reduce pollution and save open
