Abstract: In the process of crop growth, some diseases, pests and weeds can affect crop plant growth and development, thus crop yield decreases. In order to improve the efficiency of resource utilization, reduce environmental pollution and make crop yield stable and sustainable, it would be helpful to apply diversified crop planting patterns, i.e. changing from planting single kind of crop in an area to a variety of crops planted together, which produces a better crop community cultivation system, thus enhances the resistant ability. This study illustrated the progress about the mechanism of resistance of crop community cultivation system mainly in six effects, respectively, pointed out the deficiency of the present study, and looked forward to the future research direction.

Key words: crop community cultivation system, diseases, pests and weeds, resistance mechanism

摘要： 作物生长过程中，病虫草害威胁着作物个体的生长发育，进而影响作物群体的生物产量。近年来研究发现，采用多样化种植方 式，由单作转变为不同类作物间作、套作，形成作物群落栽培系统，可改善群体结构、增强抗性水平，提高作物产量。综述了 作物群落栽培系统抗病虫草害的六种机制，探讨了研究中存在的问题，并对作物群落栽培系统抗病虫草害今后的研究方向作出 展望，以期为进一步研究提供理论参考。
