The invention discloses application of bacillus megaterium and bacillus licheniformis in degradation of inorganic phosphorus, and discloses a compound microbial agent for improving the phosphorus utilization rate. The compound microbial agent is composed of bacillus megaterium, bacillus licheniformis, phytase and mineral source fulvic acid/mineral source potassium fulvate, wherein the viable count ratio of the bacillus megaterium to the bacillus licheniformis is 1: (3-5), preferably 1: 4. According to experimental research, the bacillus megatherium combined with the bacillus licheniformis has excellent degradation effect on inorganic phosphorus. When the bacillus megaterium and bacillus licheniformis are prepared into a microbial agent and a compound microbial agent to be applied to soil, degradation of inorganic phosphate fertilizer in the soil is facilitated, the utilization rate of phosphorus by crops, fruits, vegetables and the like is increased, absorption of phosphorus is promoted, and curing of the phosphorus is reduced.
Description
technical field [0001] The invention relates to a composite microbial bacterial agent for improving phosphorus utilization rate, and belongs to the technical field of microbial bacterial agents. Background technique [0002] Phosphorus fertilizer occupies a very important position in agricultural planting and plays a decisive role in the harvest of crops. However, the utilization rate of phosphate fertilizer is low, generally only 10% to 25%. The main reason is that the active ingredients of phosphate fertilizer are easily converted into insoluble state and fixed in the soil, which is not conducive to the absorption of crops. Therefore, how to improve the utilization rate of phosphate fertilizer is an urgent problem to be solved. [0003] In order to make phosphorus fertilizer play a better role, the traditional methods mainly include: increasing the amount of fertilizer applied, concentrated fertilization, layered fertilization, mixed application of phosphorus fertilizer a...
