在保护地生产中,特别是一些专业化生产基地,多年连茬种植,常造成土壤和棚室中的病原菌、虫卵积累,一些土传病虫害连年发生,病情越来越重。而消费者对无公害产品的追求,也对药剂防治提出了更高要求。因此,必须更多地依靠农业综合措施,以达到对保护地内病虫害的控制。下面介绍的保护地土壤消毒技术就是一个有效控制病虫害的综合方法。
In the protected areas of production, especially some specialized production bases, continuous cropping for many years, often resulting in soil and greenhouse pathogens, egg accumulation, some earth-borne diseases and pests occur year after year, more and more serious condition. The pursuit of pollution-free products by consumers also places higher demands on the prevention and treatment of pesticides. Therefore, we must rely more on agro-comprehensive measures to control pests and diseases in protected areas. The following describes the protection of soil disinfection technology is an effective way to control pests and diseases.
