The invention discloses a method for preparing an organic fertilizer by fermenting cow dung compost. According to the method, two times of composting fermentation are adopted and a composting promoter is added, so that the fermentation speed and the composting degree can be quickly increased; meanwhile, polyacrylamide, bentonite, cocoanut active charcoal and the like are added to reduce the moisture in cow dung and achieve the effect of deodorizing; sodium bicarbonate and triple superphosphate are added to generate carbon dioxide which can expand the cow dung, so that the permeability is increased; the early-stage fermentation temperature of the cow dung can be increased by the heat released from reaction, so that the activity of natural fermentation bacteria agents in the cow dung is improved; meanwhile, when the heat generated by the cow dung after a period time of composting is overhigh, the polyacrylamide absorbs the moisture in the cow dung to achieve the effect of reducing the temperature and to reduce turning times; after the fermentation is completed, the organic fertilizer prepared by drying and dewatering is high in fertilizer efficiency, durable and efficient, has the effects of retaining water, sterilizing and improving soil, and can promote the rapid growth of crops, thus improving the yield and the quality of the crops.
