本文简要介绍中国豆科牧草根瘤菌资源的采集、保藏及利用概况,近二十年来,中国农业微生物菌种保藏管理中心从20多个省区采集豆科植物根瘤及土壤样品,分离出土著根瘤菌分离物3000多份,从中筛选出516株豆科根瘤菌优良菌种。这些菌种将作为国家重要微生物资源进行长期保藏和持续利用。在我国北方、南方及西部地区确定豆科根瘤菌接种剂定点生产厂,国家对接种剂生产实行质量检验登记管理,质量不合格者不得销售。在北方退化草原及南方退化草地改良工程中,飞机播种豆科牧草种子普遍采用丸衣化接种根瘤菌技术,利用根瘤菌与豆科植物共生固氮作用,有效地解决了人工草地的缺氮问题。
This article briefly introduced the collection, preservation and utilization of leguminosarum resources in China. In the past 20 years, China National Center for Agricultural Microbiology and Collection has collected legume nodules and soil samples from over 20 provinces and autonomous regions, and isolated indigenous root nodules More than 3000 bacterial isolates, 516 strains of Legume Rhizobium strains were screened out. These species will be long-term preservation and sustainable use as a national important microbial resource. In northern China, southern and western regions identified legume Rhizobium inoculum designated production plants, the state of vaccination production quality inspection registration management, quality unqualified persons shall not be sold. In the degraded grassland of North China and the degraded grassland improvement project in South China, the seedling of Leguminosae flies is widely used to inoculate Rhizobium bacteria. The utilization of rhizobia and symbiotic nitrogen fixation of leguminous plants effectively solves the nitrogen deficiency problem of artificial grassland.
