Method for producing organic fertilizer by using cow dung

The invention belongs to the technical field of organic fertilizer production methods, and discloses a method for producing an organic fertilizer by using cow dung. The method comprises the followingsteps: preparing materials, performing mixing, performing fermentation, performing pre-drying and performing drying. The method specifically comprises the following steps: taking the following components in parts by mass: 40-60 parts of the cow dung, 10-25 parts of straw, 8-15 parts of rice hull, 8-15 parts of soybean meal, 8-15 parts of rapeseed cake, 3-4 parts of gypsum powder, 0.05-0.1 part ofa fermentation microbial agent, and 2-8 parts of water, and fully and uniformly mixing the above components to form a pre-fermentation mixture; and placing the pre-fermentation mixture in a fermentation tank, performing fermentation on the pre-fermentation mixture at a temperature of 40-65 DEG C to form a fermented mixture, and performing drying to complete the production of the ecological organicfertilizer.
