Problems solved by technology

[0004] It can be seen that granular fertilizer is a hot spot in current research, but due to the unreasonable preparation method, the cost of traditional granular fertilizer preparation method is high, the prepared granular fertilizer is easy to agglomerate, and the nutrient loss is serious, which seriously hinders the development of fertilizer field. In view of this, the researcher made scientific improvements on the traditional preparation method, so that the prepared granular organic fertilizer can meet the current market demand for fertilizer to the greatest extent.

Abstract

The invention relates to the technical field of preparation of organic fertilizer, in particular to a preparation method of granular organic fertilizer. The preparation method comprises the following steps: (1) dewatering, (2) deodorization, (3) fermentation, and (4) granulation. The organic fertilizer is rich in nutrition and low in cost, and raw materials are readily available; the prepared granular fertilizer is difficult to cake and can effectively promote absorption of crops; animal dung and sludge are used as main raw materials and subjected to the dewatering and deodorization steps, so that under a proper condition, the nutritional components in the animal dung and the sludge are effectively retained, egg bacteria in the animal dung and the sludge are killed to the maximum extent, and odor pollutants in the animal dung and the sludge are removed; in the fermentation process, a nutrient solution is added to cultivate microorganisms in the dung and the sludge, so as to increase the nutrition content of the organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer preparation, in particular to a preparation method of granular organic fertilizer. Background technique [0002] Organic fertilizers are mainly derived from plants and / or animals, and are applied to the soil to provide plant nutrition as a carbon-containing material whose main function is to process biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances. , rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium, which can not only provide comprehensive nutrition for crops, but also have a long fertilizer effect, which can increase and update soil organic matter. Promoting the reproduction of microorganisms, improving the physical and chemical properties and biological activity of the soil, is the main nutrient for green food production. [00...
