摘要: 现代农业大面积单一作物连作种植和农药化肥的大量施用问题较为严重,造成农田生态系统日趋简单和脆弱,使作物病害发生频繁,病害流行周期越来越短,连作障碍严重发生。间作作为中国传统农业的精髓,具有增产、提高养分资源利用效率的优势。文章旨在明确间作缓解连作障碍的机制,以期为寻求缓解连作障碍的措施奠定基础。从寄主营养及生理变化、诱导寄主抗性、养分高效利用、改善土壤理化性状、抑制病原菌及土壤微生物多样性等方面对间作缓解连作障碍机制的最新进展进行了总结,明确了间作缓解连作障碍的机理,同时展望了间作缓解连作障碍的未来重点研究方向,以期为指导中国农业生产,实现农业的可持续发展提供理论和技术支持。

Abstract: The problems of continuous cropping of single crop in large area and the large amount application of pesticides and chemical fertilizers in modern agriculture are serious, which have caused field ecosystem to be simple and weak, frequent occurrence of crop diseases, shorter disease epidemic cycle, and serious continuous cropping obstacles. Intercropping is commonly practiced in China which has the advantages of increasing production and efficient nutrient resource utilization. The aim of this study is to clarify the mechanism of continuous cropping obstacle, in order to look for alleviate measures. The authors summarized the latest developments of alleviation mechanism of intercropping on continuous cropping obstacle in terms of host nutrition and physiology change, induced resistance of host, effective use of nutrition, soil physiochemical properties improvement, pathogen inhibition and soil microbial diversity, analyzed the mechanism, and proposed the research directions to guide agriculture production and provide theoretical and technical support for the sustainable development of agriculture.
