Paenibacillus kribensis CX-7 strain with the ability of solubilizing phosphate and potassium was chosen from wheat field sample of Chang an, Shanxi. The activities of strain CX-7 as biological fertilize to release P and K nutrient for plants and soil of field were determination through field experiments. We found that the application of culture fluid of strain CX-7 was able to significantly increase the content of phosphorus and potassium in plants and that in the soil. The content of potassium in the soil increased by more than 10 mg/kg, the content of phosphorus increased by 3~11 mg/kg. The average content of phosphorus in the plant increased by 15.59% and the content of potassium increased by 30.05%. By biological statistics standards, the differences between the inoculated and the control had reached significant or very significant levels. Apart from this, the yield of maize, wheat, sweat potato, rice, tobacco and cotton inoculated with CX-7 can be increased by 12.3%, 8.2%, 13.6%, 9.5%, 15.2% and 8.5%. Our results implied that Paenibacillus kribensis CX-7 strain had potential for usage as a biological fertilize.
