Abstrct：

    The purpose of this study was to evaluate the effects of corn fertilization and integrated fertilization on two commercially available phosphate solubilizing bacteria. The fertilizer efficiency test showed that: The ear weight and uniaxial ear weight of maize were treated with 1/2 fertilization amount + sterilizing solution and 1/2 fertilization amount + bacterial liquid treatment, which was significantly higher than the recommended dosage of whole fertilizer. There was no significant difference between the treatments at °Brix. The integrated fertilization application showed that: Spring was tested in acidic soil, and no organic fertilizer treatment was applied. Only uniaxial ear weight 1/2 fertilizer recommended dosage + bacterial powder treatment, significantly better than the total amount of fertilizer recommended treatment. In the application of rice husk ash biochar in base fertilizer, the recommended dosage of ½ fertilizer + bacterial powder and bacterial liquid treatment, the weight of glutinous leaves and the weight of uniaxial ears were significantly better than the recommended dosage of whole fertilizer. Test for alkaline soil in autumn: In the weight of glutinous tassel and uniaxial ear weight, it was treated with ? fertilizer + bacterial liquid and full fertilizer + bacterial powder, which was significantly better than the control group. Performance at °Brix showed that: There was no significant difference between the two treatments in the treatments.
