快生型大豆根瘤菌具有一些突出特点,如生长速度快、耐盐、耐pH范围广、具有一定的结瘤竞争性、固氮基因和结瘤基因在大质粒上等等,使得其在生产上直接应用或通过生物技术加以改造用于生产的前景广阔。国内外均有不少研究。徐玲玫、樊蕙等近年通过实验室盆栽试验,筛选出从野大豆根瘤中分离的快生型菌株中的2057、2053、2058等与中国栽培大豆共 Fast-growing soybean Rhizobium has some prominent features, such as fast growth, salt tolerance, pH range, has a certain nodulation competitive, nitrogen-fixing genes and nodulation genes in the large plasmid, etc., making it in production Prospects for direct application or adaptation through biotechnology for production are vast. There are many studies both at home and abroad. Xu Lingmei, Fan Hui and other laboratory experiments in recent years through potted plants, screened out from the rapid isolation of wild soybean nodules strains 2057, 2053, 2058 and other cultivated soybean with China
