Organic fertilizer fermentation method

Abstract

The invention discloses an organic fertilizer fermentation method which adopts pool type aerobic continuous fermentation. The method specifically comprises the following steps: A, uniformly mixing solid organic wastes, a microbial fermentation bacterial agent and auxiliary materials in proportion to obtain a fermentation raw material, wherein the solid organic wastes, the microbial fermentation bacterial agent and the auxiliary materials are in a ratio of (70-75) to (29.99-24.99) to 0.01, so that the carbon nitrogen ratio in the fermentation raw material is (25-30) to 1; B, carrying out primary aerobic fermentation not less than 7 days on the fermentation raw material at the temperature not lower than 55 DEG C to obtain a primary fermentation product; C, carrying out secondary fermentation on the primary fermentation product at normal temperature to obtain a secondary fermentation product within 10-15 days; and D, drying the secondary fermentation product to obtain an organic fertilizer. By using fresh chicken manure as a main fermentation raw material, the organic fertilizer fermentation method disclosed by the invention achieves the purposes of harmless treatment, recycling treatment and reducing treatment.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to an organic fertilizer fermentation process. Background technique [0002] The nutrients that crops need in the process of growth are nitrogen, phosphorus, potassium and other elements, and the soil will experience the problem of nutrient loss during the long-term planting process. Therefore, fertilizing the land means adding nitrogen, phosphorus and potassium to the land, thereby increasing crops. output. In the process of planting, chemical fertilizers play a very important role, but with the frequent and single use of chemical fertilizers, it also brings adverse effects to the soil environment. In the absence of sufficient organic matter, the soil particle structure is difficult to form, the adhesion between soils is difficult to form, and then the water retention capacity of the soil gradually decreases. To solve this problem, organic fertilizers came into bein...
