小麦田农药减量增效技术示范及效益分析

Demonstration and Benefit Analysis of Pesticide Reduction and Efficiency Increase Technology in Wheat Field

为实现农药减量增效和有效控制小麦田病虫害发生双重目标,在精准测报基础上,运用种子处理+封闭除草、前控病虫基数(拔节期)、后保“一喷三防”(抽穗扬花期),优选应用高效低用量农药,协调配套应用自走式喷杆喷雾机高效植保机械开展统防统治等综合措施,实现示范区较常规区农药减量20.63%,病虫综合防效有所提高,收益增加6.23%,验证了小麦田农药减量增效集成技术在本地区推广应用的可行性。

In order to achieve the dual goals of reducing the amount of pesticides and increasing efficiency and effectively controlling the occurrence of diseases and insect pests in wheat fields,on the basis of accurate forecasting,a series of comprehensive measures,such as seed treatment + closed weeding,pre-control pest base(jointing stage),and post-protection “one spray and three defenses”(heading and flowering stage) were used,the application of high-efficiency and low-consumption pesticides was preferred,and the coordinated application of high-efficiency plant protection machinery such as self-propelled boom sprayers was carried out.The results showed that the demonstration area achieved 20.63% reduction in pesticide use compared with conventional areas,the control effect had been improved,and the income had increased by 6.23%,which verified the feasibility of the integrated technology of pesticide reduction and efficiency increase in wheat fields in this area.
