Abstract: China has a large area of continuous cropping of peanut production, and continuous cropping obstacle has become one of the important factors affecting the yield of peanut. At present, the study of allelopathy has become a hot topic to reveal the continuous cropping obstacle mechanism. This paper systematically summarized the effect of continuous cropping on peanut growth, yield, quality, nutrient uptake, physiological characteristics and disease. The concept of allelopathic autotoxicity and root exudates, and the influence of root exudates on peanut growth and development were introduced. The abatement measures of peanut continuous cropping obstacles were summarized including rational crop rotation, soil sterilization, beneficial microorganisms or nutrient elements supply, and the application of comprehensive measures. The hot research topics of peanut continuous cropping obstacles were discussed in order to guide Chinese peanut production and provide theoretical and technical support for sustainable development of peanut production.
