Abstract

The invention relates to the technical field of microbial compound fertilizers, in particular to a preparation method of microbial granules, which comprises the following steps: step 1, adding beneficial microbial liquid into a mixed nutrient solution, adding porous hydroxyapatite into the mixed nutrient solution, and carrying out aeration treatment to obtain microbial-loaded porous hydroxyapatite; step 2, uniformly mixing the microorganism-loaded porous hydroxyapatite and an ultrafine protein powder, and adding the mixture into a granulator for granulation to obtain beneficial bacterium granules; and step 3, adding the beneficial bacterium granules and patite loaded with a halophilic microorganisms into a pelletizer for pelletizing to obtain a product. The problem that in the prior art, microbial strains make direct contact with compound fertilizer, and consequently the survival rate of microorganisms is low is solved. The beneficial bacteria grains in the microbial grains are used asinner cores, and the apatite loaded with halophilic microorganisms is used as an isolation layer. Due to the existence of the apatite loaded with halophilic microorganisms, beneficial bacteria grainscan be protected, so that the survival rate of the beneficial bacteria is improved.

Description

technical field [0001] The invention relates to the technical field of microbial compound fertilizer, in particular to a preparation method of microbial bacterium particles, microbial compound fertilizer and the preparation method. Background technique [0002] Soil is mainly composed of minerals, organic matter and microorganisms. The activity of microorganisms in the soil micro-ecological zone is very important for the nutrition of plant roots, because the beneficial microorganisms in the soil are directly involved in the formation of soil fertility, including the transformation of substances and energy in the soil. , the formation and decomposition of humus, the release of nutrients, the fixation of nitrogen, etc. However, in a purely natural state, the number of beneficial microorganisms is not enough, and the action force is also limited. Therefore, using "artificial methods" to increase the number of beneficial microorganisms in the soil can increase the number and ov...
