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.
