Problems solved by technology

Existing organic fertilizers are basically made through simple processing and simple fermentation of raw materials (mainly in the form of aerobic fermentation). The fertilizers are mixed, and the fertilizer efficiency is difficult to guarantee. Some even have harmful colonies, which can be used directly and harmfully.

Embodiment 1

[0049] For fermentation in a greenhouse, add the collected wet cow dung to anaerobic fermentation bacteria, mix well, and pile up multiple ridges with a width of 4 meters, a length of 50 meters and a height of 1.5 meters in the greenhouse, and cover them with polyethylene film for sealing , Turn over once every 10 days, and the cow dung will be decomposed in 45 days.

Embodiment 2

[0051] Fermentation in a sealed warehouse, with an area of ​​280 square meters and a height of 3 meters. The warehouse wall is thickened, and the warehouse wall and roof are connected by seamless cement pointing joints (the drainage pipe is reserved under the floor of the warehouse, and the sewage is regularly discharged, and the sewage slot It must have a sealing function), reserve a feed inlet on the wall, after mechanical feeding, seal it outside, and decompose after 15 days.

[0052] Ingredients processing:

[0053] Specific implementation: Use 20 tons of the above-mentioned dry cow dung (moisture ≤ 20%), powdery humic acid (organic matter content 45% humic acid content 35% moisture ≤ 20%) 1 ton, and moisture 17% powdered clay 2 tons, 1 kg of beneficial biological bacteria, fully mixed mechanically in the production workshop, produced according to the process, and finally produced 19.2 tons of finished products. And the main nutrient content of the finished product was in...

Abstract

The invention provides an organic fertilizer prepared by anaerobic fermentation with cow dung as a main material. The preparation method of the efficient and harmless organic fertilizer comprises the steps of: carrying out anaerobic fermentation and dehydration treatment on the cow dung which is used as the main material to prepare dry cow dung; then mixing the following components in parts by weight: 200-250 parts of dry cow dung, 10-15 parts of humic acid and 20-25 parts of clay; adding a proper amount of beneficial microbial strains; fully stirring; and carrying out pelletizing, polishing, drying, checking, metering and packaging and the like to prepare the organic fertilizer with uniform particles. The active nutrients of the organic fertilizer are not damaged, the fertilizer efficiency can be exerted to the maximum extent, and the granular organic fertilizer has rich beneficial microbial strain content, unique mixing raw materials, scientific formulation, high fertilizer efficiency and wide application and is convenient to apply.

Description

technical field [0001] The invention relates to the field of organic fertilizer processing, in particular to an organic fertilizer made from cow dung as the main material through anaerobic fermentation and a preparation method thereof. Background technique [0002] With the development of livestock and poultry breeding industry, the pollution of livestock and poultry manure has become an urgent problem to be solved. On the one hand, livestock and poultry manure is a source of pollution, but also contains a large amount of N, P, K and other substances, and is a source of organic fertilizer rich in nutrients. Existing organic fertilizers are basically produced through simple processing and simple fermentation of raw materials (mainly in the form of aerobic fermentation). The fertilizers are mixed, and the fertilizer efficiency is difficult to guarantee. Some even have harmful colonies, which can be used directly and harmfully. Treating livestock and poultry manure with anaer...
