Research on the Screening of Efficient Phosphate-Solubilizing Bacteria and Its Promoting Effect on Maize Growth
The paper isolated and screened efficient phosphorus-solubilizing bacteria from the rhizosphere soil of crops in saline alkali cultivated land,and evaluated the phosphorus-solubilizing ability of the strains by combining the phosphorus-solubilizing bacteria screening method and molybdenum antimony resistance colorimetric method;This paper analyzes the effect of bacterial strains on the growth of corn through experiments on promoting growth in petri dishes and potted plants.The experimental results show that the experimental strain HF6.0 has the ability to dissolve inorganic phosphorus,which can increase the effective phosphorus content in the fermentation broth by 144.607 mg/L,meeting the national standard requirements;Phosphate-solubilizing bacteria has a significant promoting effect on maize plants and has great potentials for application in improving the fertility of saline alkali soil.
