摘　　要：随着苜蓿种植面积的逐渐扩大和集约化程度的逐步提高,苜蓿病害的发生越来越严重,其中苜蓿根部病害是制约其生产的主要因素之一。本研究从引起苜蓿根部病害的真菌种类、真菌的致病性、测定方法以及影响苜蓿根部入侵真菌的因素,综述了25年来国内外苜蓿根部病害的研究现状,提出了未来苜蓿根部入侵真菌研究的主要方向,有针对性地加强病害防治工作,以期为开展苜蓿病害研究和指导其防治提供科学依据。Medicago sativa is one of the important legumes in the world. Root rot disease is one of the limiting factors for its production and persistence. Based on the literature published during the past 25 years on pathogens and their pathogenicity in the world, lots of factors affecting disease development of M. sativa were reviewed, including disease development such as plant growing period, soil fertilizer and crop rotation in the field management. Finally, some suggestions are presented for future research.
