| Abstract: | By isolating and screening in calcareous soil,71 phosphorus-solubilizing bacterial strains with obvious halo were obtained.Comprehensive factors such as phosphatase and available P solubilized by bacterial strains,pH reduction,and developmental trends of these bacterial strains were studied.Finally,6 P-solubilizing bacterial strains with stronger P-solubilizing ability but without antagonism were screened,and they were combined as flora of P-solubilizing bacteria.Fig 8,Tab 2,Ref 17 |
