- Abstract:
-
Fungi strain QL1501 was screened from the Yellow River Delta in the saline-alkali soil and was identified as penicillium oxalate. The strain QL1501 solubilized more inorganic phosphorus than organophosphorus. The maximum concentration of inorganic phosphorus was up to 85.21 mg/L. The optimum pH which was 8 was the best condition for strain QL1501. Phosphate-solubilizing ability of the strain changed little when NaCl concentration was between 1% and 5%, and the available phosphorus concentration ranged from 76.08 mg/L to 65.37 mg/L. The bacteria growth was affected when the concentration of NaCl was higher than 7%. Height, root dry weight and plant dry weight of the corn were significantly higher in inoculation of phosphate-solubilizing fungi QL1501 treatment than that of unvaccinated fungi treatment. The results suggested that as phosphate-solubilizing biological fertilizer, the phosphate-solubilizing bacterium was effective.
