Method for efficiently treating southern high-water-content cow dung to prepare organic fertilizer

Abstract

The invention belongs to the technical field of fertilizers, and particularly relates to a method for efficiently treating southern high-water-content cow dung to prepare an organic fertilizer. The organic fertilizer is prepared from, by weight, 40-70% of cow dung, 5-20% of rice bran powder, 10-35% of straw powder, 0.1-4% of an EM stock solution, 10-30% of kieselguhr and 1-10% of starch. The method has the advantages that the method is highly targeted, the southern high-water-content cow dung can be used as the raw material, and the efficiency is extremely high; the fermentation time generallylasts for 3-6 days, the fermentation period is short, and large-scaled production can be conducted; screening is not needed, and the yield is high and up to 90% or above; the using amount is low in practical application, if a same fertilization effect is achieved, the using amount can be greatly reduced, and the using amount is about two thirds or below of that of an organic fertilizer which is sold on the market currently.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a method for efficiently treating cow dung with high moisture content in the south to prepare organic fertilizers. Background technique [0002] With the continuous expansion and intensification of my country's cattle breeding industry, the problem of manure treatment in cattle farms has become prominent, mainly in the following areas: (1) Since the farms are mostly distributed in urban-rural areas, there is not enough land to accommodate the quantity Such a huge amount of feces; (2) Due to the high moisture content of the feces, it is not convenient for long-distance transportation, or it is randomly piled up or piled up beside the roadside ditch without any treatment, which not only produces a foul smell, but also breeds flies and pathogenic bacteria , but also pollute air, soil and water, etc., bringing serious environmental problems. [0003] Since most of the ...

Problems solved by technology

But this will also bring new problems to the actual composting production: (1) increase the processing equipment and produce higher energy consumption and processing costs, making it difficult to maintain the composting enterprises that have huge investment and cannot make ends meet; desiccant, resulting in a decline in the fertilizer efficiency of organic fertilizers, increasing the cost of use for growers, resulting in a decline in quality

[0006] Therefore, if one can design a method that can not only take into account the advantages of the common organic fertilizer preparation process, but also avoid the high cost caused by the drying and deodorization process, and avoid environmental pollution accidents, realize the healthy growth of crops and effectively treat high-energy fertilizers. The problem of moisture content cow dung; this has a great role in promoting the scientific improvement of cow dung processing capacity, further protection of water resources, land resources, air resources, and saving agricultural production costs
