Saline-alkaline-tolerant phosphate solubilizing bacterium and application thereof

The invention relates to the technical field of agricultural microorganisms, in particular to a saline-alkaline-tolerant phosphate solubilizing bacterium and application thereof in improvement of saline-alkaline soil. The phosphate solubilizing bacterium is bacillus megaterium, and the preservation number of the phosphate solubilizing bacterium is CCTCC M 2020453. The phosphate solubilizing bacterium can tolerate saline-alkali conditions of pH as high as 9.5 and 5.0% NaCl, has a high phosphate solubilizing function, and is especially suitable for development of biological bacterial fertilizersof phosphate solubilizing bacteria in saline-alkaline soil. 本发明涉及农用微生物技术领域，具体涉及一种耐盐碱解磷菌及其在盐碱土壤改良中的应用，其中，所述解磷菌为巨大芽孢杆菌Bacillus megaterium，所述解磷菌的保藏号为CCTCC M 2020453。本发明的解磷菌能够耐受pH＝9.5，5.0％NaCl的盐碱条件，同时具有较高的解磷功能，尤其适用于盐碱地解磷菌的生物菌肥开发。
