| Abstract: | Plant growth promoting rhizobacteria(PGPR)were screened from soybean rhizosphere soil and collected strains through qualitative analysis of phosphate solubilization and IAA.Five PGPR strains were acquired,which improved nodulation on soybean when co-inoculated with soybean rhizobia in vermiculite pot experiment.Furthermore in the soil pot experiment with Fuyang,Jining and Yanan's soils,the co-inoculation of soybean rhizobia with five PGPR strains significantly increased the number of nodules,nodule dry weig... |
