摘　　要：从连作障碍产生的原因入手,对连作导致土壤因子向不利于作物生长转变的8个方面的原因逐一进行了阐述,包括土壤养分失衡、土壤微生物结构变化、土壤化感物质富集、土壤pH变化、土壤酶活性变化、土壤盐渍化、土壤物理性状变化和土壤水分亏缺;提出AM真菌对连作障碍的抑制作用,并从AM真菌可以提高植物自身耐胁迫性以及直接改善连作土壤环境两方面进行论证,为解决连作障碍的研究提供新的方向。Starting from the causes for continuous cropping obstacle,eight reasons were elaborated,including soil nutrient unbalance,soil microbe structure change,soil allelopathy substance enrichment,soil pH variation,soil enzyme activity change,soil salinization,soil physical traits change and soil water shortage;the inhibition effect of AM fungi on continuous cropping obstacle was put forward,and it was proved from two aspects that AM fungi could improve plant self-resistant ability and directly perfect continuous cropping soil environment,which will provide new direction for study on solving continuous cropping obstacle.
