Abstract:Using the selected high efficient phosphate solubilizing strains, and mixed it with different carri-ers and vitality keeping materials, different formulations of phosphate solubilizing microbial fertilizers were devel-oped, and their effect was verified by the pot experiment. The results showed that all kinds of phosphate solubilizingmicrobial fertilizers could activate insoluble phosphorus in the soil, also could synergistically increase maize totalphosphorus, total nitrogen and total potassium accumulation, which has a positive influence on the growth and yieldof maize. Using single ear yield as index, analysis showed that for the vector F, yield increased according to such or-ders: formulations 3> formulations 2> formulations 1> formulations 4> matrix. Compared with the control, yield in-creased by 25.33%, 14.47%, 11.05%, 9.55%, 5.81%, respectively. For the vector Y, yield increased according tosuch orders: formulations 3> formulations 4> matrix > formulations 2> formulations 1. Compared with the control,yield increased by 25.03%, 24.85%, 22.55%, 12.87%, 1.05%, respectively. For the plant nutrient absorption, com-pared with fertilizer treatment, the plant nitrogen, phosphorus and potassium content of Y2, increased 75.09%,35.08% and 40.21%, which of and Y3 treatment was 62.65%, 32.89% and 46.47%. Comprehensive analysis of corngrowing, available phosphorus content in soil, total nitrogen, total phosphorus, total potassium accumulation in plants, crop production and other indicators, Y3 treatment was the best.
