    Quantitative indicators of activity of microbial fertilizer and evaluation methods of fertilizer (work efficiency) will be established to provide a reference for the future revision of the commodity specification of microbial fertilizer by the Agricultural Development and Reform Commission to ensure the quality of microbial fertilizer products and protect the rights of farmers.

    2017 of microbial fertilizer products field evaluation methods established, the test crop is feed corn, according to the amount of fertilizer in the soil to adjust the amount of farmland soil and fertilizer on the two kinds of phosphate-solubilizing bacteria regularly to observe the impact on the yield. The results showed that the effects of using phosphate solubilizing fertilizer on the yield of maize under different phosphorus contents were all different.

    2018 Establishing a field evaluation method for the fertilizer effect of phosphate-dissolving bacteria fertilizer products in Tao-yuan area and experiments of integrating phosphorus-dissolving bacteria microbial fertilizer with chemical fertilizer or organic fertilizer integrated fertilization method, Asparagus lettuce and Red Amaranth was tested in the field. The results showed that the yield difference between the treatments was not significant, although the application of the phosphate solubilizing fertilizer did not significantly increase the yield, but the reduction of the amount of chemical fertilizer and the use of phosphorus-dissolving bacteria microbial fertilizer conditions, can still achieve a certain level of production.

Keywords: Verification, Phosphate-Solubilizing Bacteria, Evaluation; Integrated fertilization methods.
