High-phosphorus slow-release bacterial fertilizer and preparation method thereof

Abstract

The invention discloses a high-phosphorus slow-release bacterial fertilizer and a preparation method thereof, and belongs to the technical field of compound bacterial fertilizers. Essentially, bacterial liquid of bacillus mucilaginosus, bacillus megaterium and white-rot fungi and humic acid or / and livestock and poultry manure are subjected to adsorption and stirring, and then granulation and drying are carried out to obtain bacterial fertilizer particles, and the bacterial fertilizer is characterized in that the viable count in the mixed bacterial liquid is 2-50*10<8>CFU / g, and the sundry bacteria rate is less than or equal to 10%. Immobilized insoluble phosphorus in soil is converted into available phosphorus capable of being utilized by plants through the biological phosphorus-dissolvingbacterial fertilizer, the utilization rate of phosphate fertilizer in soil is increased, the utilization rate of phosphate fertilizer can be increased, and the application amount of phosphate fertilizer in the soil is reduced; in addition, through compounding of bacteria, the effective viable count can be increased, and the sundry bacteria rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of compound bacterial fertilizer, in particular to a preparation method of high-phosphorus slow-release bacterial fertilizer. Background technique [0002] The production cost of microbial fertilizer is low, the application effect is good, and it does not pollute the environment. After application, it not only increases production, but also improves the quality of agricultural products and reduces the use of chemical fertilizers. Therefore, it plays an important role in the sustainable development of my country's agriculture. my country's population is increasing day by day, people's living standards are constantly improving, and higher requirements are put forward for the quantity and quality of agricultural products. Due to the continuous reduction of cultivated land in our country, the amount of chemical fertilizers used is large, the production costs are high, and chemical fertilizers will cause continuou...
