摘要
该文对西充县水稻有机栽培过程中的主要病虫害种类、防治指标和防治方法进行了概述,提出以非药物防治为主、生物农药防治为辅的防治策略。非药物防治措施包括病虫害测报和检疫、农业防治(选用优良品种、消灭越冬虫源和病源、保护天敌)、健身栽培(培育水稻壮秧、合理的大田栽培管理措施)、信息素诱杀、物理防治、生物防治(稻螟赤眼蜂控害、稻鸭共育)等6个方面;生物农药防治措施包括种子处理、秧苗带药移栽、大田虫害防治、大田病害防治(稻瘟病、稻曲病、水稻纹枯病、水稻细菌性基腐病)等4个方面。
This paper briefly summarizes the main diseases and insect pests,control indexes and control methods in the process of rice organic cultivation in Xichong County,and puts forward the control strategies which are mainly non-drug control and supplemented by biological pesticide control.Non-drug control measures include disease and pest reporting and quarantine,agricultural control(selection of good varieties,elimination of overwintering and dis⁃ease sources,protection of natural enemies),fitness cultivation(cultivation of strong rice seedlings,reasonable field cultivation management measures),pheromone trapping,physical control,biological control(rice borer Trichogram⁃ma control pests,rice and duck common fertility)and other six aspects.The control measures of biological pesticides include four aspects:seed treatment,transplanting after spraying,field pest control,field disease control(Rice blast,Ustilaginoidea virens(Cke,)Tak.,Rice sheath blight disease,Rice bacterial base rot)and so on.
