摘　　要：根瘤菌与豆科植物共生是豆科植物固氮的重要方式,苜蓿作为一种优质豆科牧草,应用苜蓿根瘤菌剂可以提升豆科牧草的固氮功能,提高苜蓿产量,降低氮肥使用量,不仅可以改善土壤结构,还能够降低农业生产成本,进而促进农业可持续发展。本文介绍了根瘤菌研究和应用概况,从根瘤菌、苜蓿根瘤菌剂及促生菌与根瘤菌共接种等方面对苜蓿生长影响进行综述,并对根瘤菌及相关菌剂研究方向进行展望。The symbiosis between rhizobium and leguminous plants is an important way of nitrogen fixation in leguminous plants.As a high-quality leguminous herbage,the use of alfalfa rhizobium agent can improve the nitrogen fixing function of leguminous herbage,increase the yield of alfalfa,reduce the utilization rate of nitrogen fertilizer,which improve the internal structure of soil,reduce the cost of agricultural production and promote the sustainable development of agriculture.Based on this,this paper introduces an overview of the research and application of rhizobia,reviewing the effects of rhizobia,alfalfa rhizobial inoculants,and co-inoculation of growth-promoting bacteria with rhizobia on alfalfa growth.Additionally,the paper looks ahead to future research directions for rhizobia and related microbial agents.
