Abstract

Phosphorus bacteria fertilizer can increase the utilization of soil phosphorus and promote plant growth. In order to provide basic information for the composite engineering strains, we selected high-efficiency phosphorus-solubilizing bacteria (PSB) from the rhizosphere of mature corn soil. In this study, a total of six organic phosphorus strains were obtained by NBRIP medium. Further experiments were performed on inorganic PSBs. We measured the dissolved phosphorus ratio (D/d values), NK2 and NK3 had the best phosphate-solubilizing effects. The D/d values of NK2 and NK3 were 2.13 and 4.35, respectively. The results of 16S rRNA amplification and sequencing showed that the NK2, NK3 were identified as Acinetobacter sp., Pseudomonas sp., respectively. According to the data of shaker experiment for 7 days, the maximum phosphate solubilizing contents of NK2 and NK3 were 183.10 mg·L-1 and 79.87 mg·L-1, respectively, and NK2 had genetic stability. The result of pot experiment indicated that the growth attributes and the root indexes of the Micro-Tom, as well as the content of soil available phosphorus treated by NK2 (TCP) and NK3 (TCP) were both significantly higher than CK (P<0.05). These results imply that above two strains could promote plant growth.
