摘　　要：根腐病作为紫花苜蓿的常见病害,严重威胁了紫花苜蓿的产量与品质,降低了经济效益。通过国内外学者研究表明,牧草根际促生菌具有防治紫花苜蓿根腐病的作用。本文通过综述紫花苜蓿根腐病的病原菌种类、发病机理、PGPR防治紫花苜蓿根腐病的方法、原理及对PGPR防治紫花苜蓿根腐病的展望,为PGPR防治紫花苜蓿根腐病的研究提供理论依据。Root rot is a common disease of alfalfa,which seriously threatens the yield and quality of alfalfa and reduces the economic benefits of alfalfa.Studies by domestic and foreign scholars show that forage rhizosphere growth promoting bacteria can control alfalfa root rot.This article describes the pathogen types and pathogenesis of alfalfa root rot,the methods and principles of PGPR control of alfalfa root rot were reviewed,and the prospect of PGPR control of alfalfa root rot was prospected,which provided a theoretical basis for the research of PGPR control of alfalfa root rot.
