摘　　要：2015年以来从国内外引进23个优良苜蓿品种(种),进行引种观察栽培试验.结果表明,苜蓿发生的病害有苜蓿褐斑病(Pseudopeziza medicaginis(Lib)Sacc.)、苜蓿菌核病(Sclerotinia sclerotiorum Lib.De Bary)和苜蓿菟丝子(Cuscuta approximata Bab.)3种.龙牧801苜蓿、美国黄花苜蓿4号、美国黄花苜蓿3号、敖汉苜蓿、WL168苜蓿、美国黄花苜蓿2号、俄罗斯苜蓿等品种牧草产量高,适应性好,苜蓿褐斑病轻,可以在当地推广种植.对引种的品种病害发病情况及对产量的影响做了较系统的分析.Disease incidence was monitored in 30 varieties of alfalfa introduced from home and abroad since 2015 and cultivated in Hulunbuir City. Diseases detected included alfalfa brown spot disease,alfalfa sclerotinia stem rot,alfalfa dodder;Longmu 801 alfalfa,American chrysanthemum alfalfa 4,American chrysanthemum alfalfa 3,Aohan alfalfa,WL168 alfalfa,American chrysanthemum alfalfa 2,and Russia alfalfa varieties provided good characteristics such as high forage yield,good adaptability,and little alfalfa leaf spot light. The pathogenesis of the diseases and their influence on yield were analyzed systematically,which could be used for reference in the production of alfalfa.
