摘要： 柽麻是山西棉麦集中产区主要速生豆科肥效较高的夏季绿肥作物。枯萎病由土壤传播系柽麻的毁灭性病害。1981-1982年通过对此病害调查研究以及一系列测定试验结果初步表明：山西省柽麻枯萎病原菌有Fusarium udum Bult。var。crotalariae和F。moniliforme两种。其中以前者致病力、寄生力较强，是造成柽麻生长初期、中期病死苗的主要因素。虽然F。moniliforme对生长初期、中期的柽麻致病力较弱，但由于它地理分布广、繁殖速度快、腐生性强，因此，柽麻花荚后期如逢淫雨多湿，以致加重病害程度，影响柽麻留种。在病害的防治上，除严格进行种子消毒外，还应加强其它综合防治方法。

Abstract: Crotalaria juncea is a main green manure in cotton and wheat produ cing areas of Shanxi.Crotalaria Fusarium wilt is a destructive and soil-borne disease.During 1981-1982,Crotalaria Fusarium wilt was investigated and the pathogens were isolated.After results of a series of investigations show that there are two pathogenic fungin(Fusarium udum Bult.var.Crotalariae and F.moniliforme).The former is a stronger pathogenic isolate.As F.moniliforme is widely distributed in crotalaria growing areas,it is suggested that not only seed treatment shouldbe applied,but also other measures,especially integrated control,should be taken against this disease.
