从新疆棉区农田生态系统整体观念出发 ,以优质高产为中心 ,组建了新疆棉花病虫害综合防治技术体系。该技术体系以新疆棉区主要病虫害为防治目标 ,通过增强、保护和利用农田生态系统中天敌调控作用的措施 ,充分发挥自然天敌对棉花害虫的控制作用 ;通过农业防治措施秋耕冬灌、合理构建作物布局和采取控害栽培技术措施 ,减少病虫的发生数量。通过科学合理使用农药 ,降低农药使用量 ,减少对农田生态环境的污染 ;棉花病虫害综合防治技术体系的组建和实施 ,获得了明显的经济、社会和生态效益。
Starting from the overall concept of farmland ecosystem in cotton area in Xinjiang, the technical system of comprehensive prevention and control of cotton diseases and pests in Xinjiang was established with the center of high quality and high yield. The technology system takes the major pests and diseases in the cotton area of Xinjiang as the prevention and control target and gives full play to the control effect of natural enemies on cotton pests by enhancing, protecting and utilizing the natural enemies’ regulation and control in agro-ecosystem. Through agricultural measures of autumn and winter irrigation, Crop layout and take control cultivation techniques and measures to reduce the number of pests. Through scientific and rational use of pesticides to reduce the amount of pesticides used to reduce the pollution of farmland ecological environment; cotton integrated pest management system established and implemented, access to significant economic, social and ecological benefits.
