[0025] b. Fermentation: Mix 90-98% of the fermentation raw materials in step a and 2-10% bacillus evenly by weight percentage, then add them into the fermentation tank, stir, pressurize in the tank, and cultivate with ventilation for 12-18 hours After that, the spores are obtained;

[0026] c, the bacterial spores obtained in step b are filtered, dried, and pulverized to obtain the bacterial agent, which is then used for subsequent use;

[0027] d. Mix and granulate 5-15% of the bacterial agent in step c, 10-30% of humic acid, 70-80% of cake, and 5-15% of medium and trace elements by weight percentage to obtain microorgani...

Embodiment 1

[0039] A production process of biological compound fertilizer, comprising the steps of:

[0040] a, the preparation of fermented raw materials: by weight percentage, 1.5% bean cake powder, 0.7% fish meal, 2.0% corn steep liquor, 0.9% starch, 0.06% magnesium sulfate, 0.7% calcium carbonate, 0.02% dihydrogen phosphate Potassium, 0.12% soybean oil, 94% water, adjust the pH value to 7-7.5, and obtain the fermentation raw materials for later use;

Abstract

The invention discloses a production process of a biological compound fertilizer. The production process comprises the following steps of: a, mixing the following components in percentage by weight: 1.0-2.0% of soybean cake powder, 0.3-1.0% of fish meal, 1.0-3.0% of corn steep, 0.5-1.5% of starch, 0.02-0.1% of magnesium sulfate, 0.3-1.0% of calcium carbonate, 0.01-0.05% of monopotassium phosphate, 0.05-0.15% of grease and 80-95% of water, and adjusting the pH value to 7-7.5 to obtain a fermenting raw material; b, uniformly mixing 90-98% of fermenting raw material and 2-10% of bacillus according to the weight percentage, adding the mixture into a fermentation tank to ferment for 12-18h to obtain a bacterial spore; c, filtering, pressing, drying and crushing the bacterial spore to obtain a bactericide; d, mixing 5-15% of the bactericide obtained in step c, 10-30% of humic acid, 70-80% of cakes and 5-15% of medium trace elements by weight percent and granulating to obtain microbial bactericide particles; and e, uniformly stirring 10-30% of microbial bactericide particles obtained in step d, 20-40% of urea, 20-40% of diammonium phosphate and 15-35% of potassium sulphate according to the weight percent to obtain the biological compound fertilizer.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers and relates to the preparation of compound fertilizers, in particular to a production process of biological compound fertilizers. Background technique [0002] The growth and development of crops requires the supply of various nutrient elements, and the source of nutrient elements is mainly fertilizers. Fertilizers are the guarantee for sustainable agricultural development and the basis for increasing crop production. After chemical fertilizers are applied to the soil, due to the influence of the properties of chemical fertilizers and soil environmental conditions, the utilization rate of the current season crops is low, only 20-40%, which not only causes a lot of waste of chemical fertilizers, but also reduces the quality of agricultural products. The use of eutrophication will make lakes, rivers, and reservoirs more and more eutrophic, and the concentration of nitrate in groundwater will ...
