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。
In the process of crop growth, pests and diseases threaten the growth and development of crop individuals, thereby affecting the biological yield of crop groups. In recent years, the study found that using a variety of planting methods, changing from single cropping to cropping and cropping of different crop types, crop cultivation systems can be improved to improve population structure, enhance resistance and increase crop yield. Six kinds of mechanisms of cropping system against diseases and insect pests were reviewed, the problems in the research were discussed, and the future research directions of crop cultivation system against pest and weed were also prospected in order to provide theoretical reference for further research.
