摘　　要：设施栽培条件下,蔬菜连作障碍逐年加重,生产上通常采用的防治方法均存在一定的局限性。随着无公害蔬菜的发展,AM菌根生物技术在设施蔬菜生产上的应用逐渐成为研究的热点。AM菌根是丛枝菌根菌与植物根系形成的共生体,在自然条件下,大多数植物表现一定的菌根依赖性,许多研究证实AM菌根可以提高植物在逆境条件下的生存能力,促进宿主植物的生长。文章对AM菌根生物技术克服设施蔬菜连作障碍方面的潜力进行了初步探讨。In Protected cultivation condition,continuous cropping obstacle has been increasing year by year.The common methods usually have certain limitations.With development of the nonpolluted vegetables,the application of AM has gradually become the research hotspot.AM mycorrhiza is a symbiont which formed by arbuscular mycorrhizal fungi and plant root,under natural conditions,most plants show a certain degree of mycorrhizal dependency,many studies have confirmed that AM fungi can improve plant survival under adveerse conditions, and promote host plant growth. This paper has an analysis about AM overcome continuous crop ping obstacles in protected vegetable cultivation.
