１９８１年以来，筛选出了几十种豆科牧草根瘤菌菌种，并在我国南方和北方建立了根瘤菌剂生产基地，在全国飞播牧草区大面积推广种子丸衣化接种根瘤菌技术，１９９３年累计接种面积为７０万公顷。接种根瘤菌提高了飞播牧草的成苗率，促进了共生固氮，提高了牧草产量和质量，为我国豆科牧草人工草地的建植起到了重要作用。 Since 1981, dozens of Rhizobium strains of leguminous pasture have been screened and Rhizobium strains have been established in the southern and northern part of China. Rhizobium is widely used in the aerial planting of pasture areas in China. 1993 Inoculation area of ​​700000 hectares. Rhizobium inoculation increased the seedling rate of aerial seeding pasture, promoted symbiotic nitrogen fixation and improved the yield and quality of pasture, which played an important role in the establishment of legume pasture grassland in China.
