摘　　要：连作障碍是园艺作物栽培中经常发生的现象,会给园艺作物栽培造成严重损失。为解决连作障碍问题,国内外学者开展了大量的研究工作,从多个角度对连作障碍的原因进行了分析。针对砂田西瓜生产中存在的实际问题,从土壤功能的劣化、真菌土传病害和化感自毒作用3个方面综述了砂田西瓜连作障碍的原因,分析了土壤理化性质、酶活性和土壤微生物多样性变化对砂田西瓜连作障碍的影响,探讨了土传真菌病害枯萎病的致病机制,总结了西瓜化感自毒作用对西瓜生长的影响,阐述了化感物质的主要成分和来源,提出了克服砂田西瓜连作障碍的具体措施,并对砂田西瓜连作障碍的研究现状进行了展望。The continuous cropping obstacle is a frequent occurrence in horticulture crop cultivation, it brings great loss to agriculture production. In order to solve continuous cropping obstacle problem, many scholars had done a lot of research from many aspects and analysized the reasons of continuous cropping obstacle. According to the problem of watermelon production, the research progress of soil function deterioration, fungi soilborne disease and allelopathic autotoxicity were expatiated and summed up here in. In this paper, the effect of soil physical and chemical properties, enzyme activity, the soil microbial diversity on continuous watermelon production obstacle were analyzed, the pathogenesis mechanism of soilborne diseases was discussed, the effect of allelopathic autotoxicity on watermelon growth was summarized, concrete measures of overcoming watermelon obstacle were provided, utilization in agriculture production of the allelochemicals production is in prospect.
