摘要: 从生态效益和长期效应来看,混作对防治作物病虫草害和保护、改善农田生态都起到一定积极作用。文章简述了品种和种植结构单一对农田生态的风险,通过对应用实例的概括,从屏障效应、化感作用、稀释效应以及组分间互作等方面,总结归纳了混作的作物保护机理。分析指出混作科学搭配措施、长效评价和补偿机制缺乏等问题,并对混作的应用前景提出展望。

Abstract: From the points of ecological benefit and long-term effect, mixed cropping can play a positive role in controlling crop disease, pest and weed, and protecting and optimizing farmland ecosystem. In this review, the ecological risks of simplified variety type and crop pattern were briefly described. Through reviewing application examples, the crop protection mechanisms of the mixed cropping were summarized into the barrier effect, allelopathy, dilution effect as well as the interaction effect between components in the mixed system, etc. The lack of scientific collocation, benefits evaluation and compensation mechanism in the application of mixed cropping were pointed out, and the application prospect of the mixed cropping was put forward.
