Abstract

The invention relates to a compound bacterial fertilizer based on biogas slurry and a preparation method thereof, and belongs to the field of biological fertilizer. In view of the problem of bacterialfertilizer preparation based on biogas slurry and compounded with various beneficial microorganisms, the invention provides the composite bacterial fertilizer based on the biogas slurry, wherein thecomposite bacterial fertilizer is prepared from the following raw materials by the mass percentage: 10%-50% of the biogas slurry, 0.2%-10% of a culture auxiliary material, 0.25%-2.5% of a composite microbial liquid, and the balance water. The culture auxiliary material is prepared by mixing sodium chloride, glucose, potassium dihydrogen phosphate, magnesium sulfate, sodium acetate, ammonium bicarbonate, potassium sulfate, corn flour, soybean flour, calcium carbonate and glycine; the compound microbial liquid is obtained by fermenting with bacillus subtilis, lactic acid bacteria, photosyntheticbacteria and yeast, and the concentration of the composite microbial liquid is 1-2*10<8> CFU / ml. The biogas slurry, the culture auxiliary material and water are mixed in proportion and then added into a fermentation pool, then the mixture is inoculated with the composite microbial liquid in proportion, then uniform mixing is performed, and fermentation is performed to obtain the compound bacterial fertilizer. The compound bacterial fertilizer is suitable for the development and utilization of the microbial fertilizer.

Description

technical field [0001] The invention relates to a compound bacterial fertilizer based on biogas slurry and a preparation method thereof, belonging to the field of biological fertilizers. Background technique [0002] Biogas slurry is a brown and bright liquid formed by the fermentation of organic matter. It is a by-product of biogas production. It contains a variety of amino acids and trace elements and is a good feed additive. Biogas slurry is not only rich in nitrogen, phosphorus, potassium and other macronutrients and zinc and other micronutrients, but also contains 17 kinds of amino acids and active enzymes. These nutrients basically exist in the form of quick-acting nutrients. Therefore, biogas slurry has strong quick-acting nutrient capacity and high nutrient availability. It is a multi-variety quick-acting compound fertilizer that can be quickly absorbed and utilized by animals and crops. [0003] Commercial aquaculture is mostly based on high-density and intensive f...
