摘　　要：综述了花生连作障碍的研究现状及进展。从土壤营养失调、病虫害危害严重、化感自毒物质积累、土壤酶活性下降、土壤微生物区系变化等角度阐述了花生连作障碍的产生机理,并介绍了当前治理花生连作障碍的各项防控措施,最后对花生连作障碍的机理研究及防控技术发展方向提出了展望。The situation and progress of peanut continuous cropping obstacles were summarized.The mechanism of continuous cropping obstacles was reviewed in the sight of soil nutrient unbalance,serious hazard of diseases and pests,accumulation of allelopathy roots exudates,decrease of soil enzyme activity and change of soil microbial flora.The counter measures were also reviewed in controlling the obstacles of peanut continuous cropping.And some future researches and controlling techniques directions of peanut continuous cropping obstacles were proposed in the end.
