Problems solved by technology

[0004] 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 reduces the effective yield, which takes a long time

Embodiment 1

[0044] A method for composting poultry manure, comprising the steps of:

[0045] S1 gets stuffing:

[0046] a. First-level packing: the first-level packing is obtained by cutting the double-layer paper entrained with mud and curling multiple layers along the axial direction. The first-level packing includes at least large packing and small packing. The volume of the large packing and the small packing is The ratio is 2:1;

[0047] b. Secondary filler: calcining part of the primary filler at 500°C for 60 minutes to obtain the secondary filler.

[0048] The first-level filler and the second-level filler realize soft and hard support structures, which provide better pore structure support during the entire fermentation process, and the second-level filler is calcined from the first-level filler, and its slurry is calcined to form curls The structure and surface microporous structure can embed part of the fertilizer to slow down the release of fertilizer effect, so that the crop...

Embodiment 2

[0064] S1 gets stuffing:

[0065] a. First-level packing: the first-level packing is obtained by cutting the double-layer paper entrained with mud into sections in the axial direction after curling multiple layers. The first-level packing includes at least large packing and small packing, and in this embodiment, the large packing and The volume ratio of the small filler is enlarged to 3:1;

[0066] b. Secondary filler: calcining part of the primary filler at 550° C. for 40 minutes to obtain the secondary filler.

[0067] S2 Mixing of raw materials: Mix 300 parts by mass of poultry manure, 6.5 parts by mass of primary filler, 7 parts by mass of secondary filler and 7 parts by mass of microbial agent, and stir evenly.

[0068] Other steps are the same.

Embodiment 3

[0070] S1 gets stuffing:

[0071] a. First-level packing: the first-level packing is obtained by cutting the double-layer paper entrained with mud and curling multiple layers along the axial direction. The first-level packing includes at least large packing and small packing. The volume of the large packing and the small packing is The ratio is 2:1;

[0072] b. Secondary filler: calcining part of the primary filler at 650° C. for 40 minutes to obtain the secondary filler.

[0073] S2 Mixing of raw materials: Mix 400 parts by mass of poultry manure, 8 parts by mass of primary filler, 8 parts by mass of secondary filler and 7 parts by mass of microbial agent, and stir evenly.

[0074] Other steps are the same.

Abstract

The invention discloses a poultry manure composting method which comprises the following steps: S1, acquiring fillers: a, primary fillers: rolling double-layer paper with slurry for multiple layers, and cutting the rolled paper into sections in the axial direction to obtain the primary fillers which at least comprise large fillers and small fillers, and the volume ratio of the large fillers to thesmall fillers is (2-4):1; b, secondary fillers: calcining part of the primary fillers at the temperature of 500-800 DEG C for 30-60 min to obtain the secondary fillers; S2, raw material mixing: mixing 250-500 parts by mass of poultry manure, 5-10 parts by mass of the primary fillers, 5-10 parts by mass of the secondary fillers and 6-8 parts by mass of a microbial agent, and uniformly stirring; and S3, fermentation: putting the mixture into a fermentation tank for fermentation, and thus obtaining a fermented material when the pH value is measured to be 7-7.8. According to the method, the poultry manure is high in fermentation degree, quick in decomposition and free of stink, the utilization rate of waste resources is increased, the production cost is reduced, the physical and chemical properties of soil can be improved, the proportion of beneficial microorganisms in rhizosphere soil is adjusted, and chemical pesticides and chemical fertilizers can be completely replaced.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a poultry manure composting method 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, it is difficult to deal with a large number of poultry manure produced in a centralized manner, and it is difficult to achieve harmless treatment, resulting in serious pollution to the surrounding environment, and Cause a large amount of waste of resources again, be difficult to effectively utilize poultry manure. However, poultry manure is the traditional raw material of farmyard manure, which has high organic content and rich nutrition. However, the traditional direct manure composting takes a long time, the effective yield is low, and at the same time, it will cause new environmental pollution. Therefore, far...
