摘　　要：[目的]为培肥土壤、提高紫云英产量、恢复和发展安徽绿肥生产提供理论依据。[方法]通过田间试验,筛选与当地紫云英品种匹配的根瘤菌。[结果]施用根瘤菌有利于紫云英生长,增加结瘤率。根瘤菌与植株进行共生固氮,幼苗生长健壮,可确保紫云英安全越冬。根瘤菌能促进紫云英营养生长,对产量提高有一定的效果。[结论]4号菌剂的应用效果优于1号菌剂。[ Objective ] The research aimed to provide the theoretical basis for the improvement of soil fertility and the yield of Astragalus, and the recovery and the development of green manure production in Anhui. [ Method] The rhizobium matching with the local AstragaIus varieties was screened by field experiment. [ Result] Application of rhizobia was beneficial to the growth of Astragalus, and could increase the rate of nodulation. The rhizobia and the plants had symbiotic nitrogen-fixation, which made the seedling strong, and ensure Astragulus safe in winter. The rhizobia also promoted the vegetative growth of Astragalus, and increased the yield. E Conclusion ] The application effect of fungicide 4 was better than that of fungicide 1.
