研究和实践证明,把某些作物通过间作、套种或混种等形式合理搭配种植,往往可以控制或减轻某些病虫害的发生,从而收到“不施农药,胜施农药”的效果。现举例如下。1.麦棉套种这种配植方法对控制棉花苗期蚜虫十分有利。麦套棉由于小麦的屏障作用,不仅直接影响棉蚜迁入,而且棉田温 Research and practice have proved that it is often possible to control or mitigate the occurrence of some pests and diseases by reasonably collocating some crops through intercropping, interplanting or mixed planting, and thus receive the effect of “not applying pesticides and winning pesticides.” Here is an example as follows. 1. Wheat Interplanting This method of planting cotton aphids control of the seedling is very favorable. Wheat cotton cotton barrier effect, not only directly affect the cotton aphid immigration, and cotton field temperature
