设施农业的连作和盲目的管理行为,出现了保护地土壤质量退化、土传病害加重等一系列制约可持续生产的严重问题。针对这些问题,提出了以农业防治、物理防治为主,化学防治为辅的综合防治技术。辽宁省凌源市的实践证明:夏季休耕时期利用太阳能高温闷棚,对保护地植物根茎部病害的防治效果可达95%以上;用77%硫酸铜钙可湿性粉剂与70%甲基硫菌灵可湿性粉剂1∶1复配,稀释成800~1 000倍液,再加1 g/亩ABT生根粉灌根,防治效果可达50%~60%。
Continuous cropping and blind management of facilities and agriculture have led to a series of serious problems that have constrained sustainable production, including degraded soil quality and increased soil-borne diseases in protected areas. In response to these problems, we put forward a comprehensive prevention and treatment technology that is mainly based on agricultural control and physical prevention and supplemented by chemical prevention and control. Lingyuan City, Liaoning Province, the practice proved that: the summer fallow period use of high temperature boredom solar greenhouse plant rhizome disease control effect of up to 95%; 77% copper sulfate calcium WP and 70% methyl thioacetate Spirit wettable powder 1: 1 compound, diluted to 800 ~ 1000 times solution, plus 1 g / acre ABT rooting root irrigation, control effect of up to 50% to 60%.
