Problems solved by technology

The biggest obstacle to the direct use of fresh chicken manure as fertilizer is that the viscosity of chicken manure itself is high, the water is heavy, and there are disadvantages such as not easy to disperse, not easy to be absorbed, and easy to soak seeds, etc.

Embodiment 1

[0015] Embodiment 1, a kind of method utilizing sweet potato dregs to prepare chicken manure, comprises the following steps:

[0016] a. Utilize the pulping machine to make the sweet potato dregs into pulp, then use a solid-liquid separator to separate the solid and liquid to obtain the sweet potato dregs; then dry it and make it into sweet potato dregs powder with a fineness of 100 mesh;

[0017] B, get the following components by weight: sweet potato slag powder 500kg, chicken manure 500kg, the two are fully stirred into pellets by a mixer;

[0018] c. Add high-temperature aerobic fermentation bacteria to the granular material obtained in b and fully stir to obtain a mixture; wherein, the weight ratio of the granular material to the high-temperature aerobic fermentation bacteria is 8: 1.2; high temperature is better in this embodiment. The oxygen fermentation strain is Bacillus subtilis, Bacillus licheniformis, Bacillus macerans, Trichoderma reesei or Paenibacillus, and its ...

Embodiment 2

[0020] Embodiment 2, a kind of method utilizing sweet potato dregs to prepare chicken manure, comprises the following steps:

[0021] a. Utilize the pulping machine to make the sweet potato dregs into pulp, then use a solid-liquid separator to separate the solid and liquid to obtain the sweet potato dregs; then dry it and make it into sweet potato dregs powder with a fineness of 200 mesh;

[0023] c. Add high-temperature aerobic fermentation bacteria to the granular material obtained in b and fully stir to obtain a mixture; wherein, the weight ratio of the granular material to the high-temperature aerobic fermentation bacteria is 8: 1; high temperature is better in this embodiment. The oxygen fermentation strain is a mixture of Bacillus subtilis, Bacillus licheniformis and Paenibacillus, and the quality of the mixed strain...

Embodiment 3

[0025] Embodiment 3, a kind of method utilizing sweet potato dregs to prepare chicken manure, comprises the following steps:

[0026] a, the sweet potato dregs are made into pulp by a pulper, and then solid-liquid separation is carried out to it with a solid-liquid separator to obtain sweet potato dregs; then it is dried and made into sweet potato dregs powder with a fineness of 160 mesh;

[0027] B, take the following components by weight: sweet potato slag powder 65, chicken manure 35, the two are fully stirred into pellets by a mixer;

[0028] c. Add high-temperature aerobic fermentation bacteria to the granular material obtained in b and fully stir to obtain a mixture; wherein, the weight ratio of the granular material to the high-temperature aerobic fermentation bacteria is 10:1; high temperature is better in this embodiment. The oxygen fermentation strain adopts the mixture of Bacillus subtilis and Paenibacillus, specifically 100kg;

[0029] d. Put the mixture in c into...

Abstract

The invention discloses a method for preparing chicken manure fertilizer by sweet potato residues. The method utilizes the sweet potato residues and chicken manure as raw materials to prepare fertilizer with high nutritional value through a fermentation process so as to greatly improve the use value of the sweet potato residues and chicken manure. According to the invention, two types of waste which are difficult to treat are ingeniously combined and used so that the waste is changed into valuable thing, the environmental problems are solved, simultaneously, after the sweet potato residues are fermented by high-temperature aerobic fermentation strains, nutrition and microelement are provided for plants to supply physiological and physical environment such as glycoprotein, organic acid, cellulose, nucleic acid and the like for microbial reproduction; simultaneously the fertilizer contains various nutrition such as amylase, glucoamylase, protease, cellulose and the like required by plants, and nutritional value is very high; and decomposed cellulose and nucleic acid have the effect of degrading heavy metals in chicken manure through absorption and flocculation, so that soil hardening and virose virosis can be reduced.

Description

technical field [0001] The invention relates to a method for recycling sweet potato dregs, in particular to a method for preparing chicken manure from sweet potato dregs. Background technique [0002] As one of the main raw materials of starch production plants, sweet potato consumes a lot. In the process of utilizing sweet potatoes to produce starch, in order to ensure the quality and color of starch, sweet potato dregs must be removed. It is very difficult to deal with a large amount of sweet potato dregs produced by starch factories. One of the existing treatment methods is to directly bury it, which not only occupies the field, but also rots and smells, polluting the environment. Another treatment method is to clean it and use it as a feed raw material, but as a feed raw material, not only the nutritional content does not meet the standard, but also the processing cost is relatively high. [0003] As we all know, because the chicken manure is directly discharged from ...
