Fermentation method of poultry manure mixed biochar and organic fertilizer product thereof

Abstract

The invention discloses a fermentation method of poultry manure mixed biochar, which comprises the following steps: S1, obtaining a segment-shaped material: rolling biochar entrained by double-layer paper for multiple layers, and cutting the rolled biochar into segments along the axial direction, wherein the segment-shaped material at least comprises a large material and a small material, and thevolume ratio of the large material to the small material is (2-4):1; and S2, mixing the raw materials: mixing 100-200 parts by mass of poultry manure, 10-15 parts by mass of the segmented material, 5-10 parts by mass of charcoal and 2-5 parts by mass of a microbial agent, and performing uniform stirring. According to the method, various volumes of segmented materials and biochar are mixed into thefermentation raw materials, and at least three-stage pore adjustment is formed in the thick-slurry poultry manure, so that the air circulation degree is improved, the available oxygen amount is increased, the degradation of organic matters is promoted, the degradation process is shortened, and the effective yield is increased; moreover, the segmented material structure is slowly decomposed, a support can also be formed in the fertilizer, a certain pore structure is generated, the air permeability and permeability of the fertilizer are improved, and the physical and chemical properties of soilare improved.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a fermentation method of poultry manure mixed with biochar and an organic fertilizer product thereof. Background technique [0002] With the construction of new countryside, poultry breeding is gradually industrialized, and the number of large-scale farms is increasing year by year. However, the utilization rate of poultry manure produced in large quantities is low, difficult to deal with, and serious pollution. Poultry manure is the traditional raw material of farmyard manure, which has high organic matter content and rich nutrition, but the effective yield of traditional direct manure composting is low, so farmers are not motivated to deal with it. [0003] my country is still a large agricultural country, and a large amount of straw is produced in agricultural production. Among them, the straw of corn, rice, wheat and other staple crops is as high as 700 million tons per y...

Problems solved by technology

However, poultry manure is generally in the form of thick slurry, and the accumulation and extrusion during composting further cause the internal pores to shrink, resulting in insufficient internal oxygen, and the conversion to anaerobic fermentation, resulting in a decrease in effective yield
