| 摘要: |
| 本实验分析了分离自宁夏沙坡头地区的２０株根瘤菌和２６株参比菌的１２５项生理生化性状，经数值分类表明，全部供试菌株在８４％，相似性水平上分为１２个亚群，未知菌与各已知菌群差异明显，其中１３个菌株分别组成３个亚群，其分类地位有待于进一步分析确定。 |

| Abstract: |
| Twenty rhizobia isolated from Shapotou region in Ningxia autonomous region and 26 reference species of Rhizobium and Bradyrhizobium were characterized by numerical taxonomy. The results based on 125 phenotypical features showed that all tested strains were divided into 12 subgroups at 84%similarity level. 13 new isolates were different from the reference strains and divided into 3 subgroups. |
