水稻病虫防治长期以来依赖于化学药剂,对环境、稻谷造成污染。且病菌害虫易产生抗药性,从而使病虫为害依然严重。浙农大陈绣副教授等从1975年起针对这一问题进行综合防治研究,从生态学角度探求建立有效的综合防治技术体系。在此基础上取得以下效益。 1.搞清了稻田生态系中水稻—主要病虫—天敌之间各项防治措施的相互关系,掌握了主要病虫和天敌的发生消长及年度间种群变动的规律,确定了药剂防治指标。特别是对稻虱、黑肩绿盲蝽、稻曲病的生物学、生态学特性的研究比前人更为完整,从而为综合防治提供了
Rice pest control has long relied on chemical agents to pollute the environment and rice. And bacteria and pests prone to drug resistance, so that pests and diseases are still serious. Associate Professor Chen Zhe of Zhejiang University of Agriculture from 1975 on the issue of comprehensive prevention and control research, from the ecological point of view to establish an effective integrated control technology system. On this basis, the following benefits have been achieved. 1. Identify the relationship between rice-pest-pest-predators in paddy field ecosystem, master the growth and decline of major pests and natural enemies and population fluctuation during the year, and determine the indicators of pesticide control. Especially for the louse, Black-shouldered Apolygus, false smut disease biology, ecological characteristics of the study more complete than the previous, so as to provide a comprehensive prevention and control
