Embodiment 1
[0023] A method for granulating microbial fertilizer, the steps comprising:
[0024] Step 1: Carry out solid fermentation of the organic material containing microorganisms to obtain bacterial fertilizer, and then shape and granulate the bacterial fertilizer to obtain bacterial fertilizer granules, the microbial bacteria is Bacillus subtilis, and the organic material is cow dung;
[0025] The operation of solid fermentation is as follows: ferment under the ventilation condition of 0.4vvm ventilation, stir, aerate, naturally heat up, and ferment for 5 days under the conditions of controlling temperature at 35°C, oxygen content at 8%, and pH value at 6;
[0026] Step 2: Place the bacterial fertilizer particles in a steel wire ball mill for stirring to perform surface mechanical activation treatment;
[0027] Step 3: Prepare modified starch with a particle size of 0.01-1 μm and aerated concrete powder with a particle size of 50-70 μm respectively, mix the modified starch with the ...
