摘　　要：为揭示根瘤菌肥对紫云英生长的影响，在湖南宜章和醴陵两地对紫云英分别进行了种植试验。结果表明：接种根瘤菌肥能提高紫云英总苗数3．9万～6．3万株／hm2、株高8．20-20．93cm、单株分枝数0．53～1．43个、单株鲜重0．64～0．65g、每株结瘤数4．4～8．4个，对提高紫云英的产量与质量具有重要意义。In order to explore the effect of rhizobium fertilizer on the growth of Astragalus sinicus ,the research planted and tested Astragalus sinicus in Yizhang and Liling in Hunan Province.The results indicated that inoculation of rhizobium fertilizer increased the total number of seedlings to over 39 000-63 000 per hectare ,promoted plant height to over 8.20-20.93 cm ,elevated number of branches to over 0.53-1.43 pie per plant ,fresh weight to over 0.64-0.65 g per plant, and increased number of nodulation to over 4.4-8.4 pie of Astragalus siuicus.It suggested that inoculation of rhizobium fertilizer could effectively improve the yield and quality of A stragalus s inicus.
