我国农作物病虫害生态调控实例分析

摘要  从改造病虫害发生区的生态环境、合理调整作物布局、实施合理种植制度、加强栽培管理几个方面,用已往通过生态调控措施成功地控制病虫害以及因不合理改制或栽培管理粗放造成病虫害大发生的典型例子进行分析。由此得出两点体会:1.在推行栽培制度、作物布局改革和作物品种更替时,一定要考虑其对农作物病虫害发生动态的影响,以有利于控制病虫害或至少不加重病虫害的发生危害为基本原则。2.需要进一步分析病虫害种群动态受作物布局及耕作制度制约的机理,由此制定合理的生态调控措施。

In this paper,a series of examples from China,including those successfully using ecological regulation strategies to keep crop pests under control and those making more damages of crop pests causing by wrong cropping systems,crop distributions or extensive cultivation,were given and analyzed.From these,two experiences were enlightened as follows: the first,the reforms of cropping systems and crop distributions must be beneficial to pest control or at least not increase the damage of crop pests;the second,th...
