| Abstract: |
| An investigation was made on the nodule and nitrogen fixation resources of wild leguminous plants in partial regions of Qilian Mountains, in order to provide valuable germplasm resources of rhizobial for agricu
ltural production and ecological environment construction. Totally 427 nodule samples belonged to 9 genera and 32 species were collected. The results showed: (1) The most nodules were yellow or brown, sphericalor claviform and coralliform, distributed on lateral root or fibre. (2) The ecological factors especially the landform, the humidity and fertility of soil were important factors that affected the nodulation. |
