Livestock and poultry manure composite phosphate furfural residue organic fertilizer and preparation method thereof

Abstract

The invention belongs to the technical field of organic fertilizer preparation, and discloses a livestock and poultry manure composite phosphate furfural residue organic fertilizer and a preparation method thereof. The livestock and poultry manure composite phosphate furfural residue organic fertilizer is composed of chicken manure, composite phosphate, furfural residue, acidophilic microorganisms, composite bacillus and a mould bacterial liquid. The preparation method comprises the following steps: disinfecting and drying selected livestock and poultry manure; uniformly stirring chicken manure, composite phosphate, furfural residues, acidophilic microorganisms and composite bacillus, and putting the mixture into a fermentation tank for sealed fermentation; adding mould liquid in the laterperiod of fermentation; when the material is black brown, completing the fermentation; and sequentially granulating and bagging the fermented organic fertilizer. The chicken manure composite phosphate furfural residue organic fertilizer prepared by the method is easily absorbed and utilized by plants; deodorization and sterilization are conducted through a one-step method, the deodorization efficiency reaches 85% or above, and the escherichia coli killing rate exceeds 99.9%; under the action of composite acid microorganisms, the utilization rate of phosphate is increased; and the air qualitycan be improved and environmental pollution sources can be eliminated by utilizing the adsorption effect of the acidic furfural residues.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer preparation, in particular to a livestock and poultry manure composite phosphate furfural slag organic fertilizer and a preparation method thereof. Background technique [0002] At present, chicken manure is a relatively high-quality organic fertilizer, which contains about 1.63%, 1.54%, and 0.085% of pure nitrogen, phosphorus (P2O5), and potassium (K2O). Chicken manure must be decomposed by a decomposing agent before application. The parasites and their eggs in chicken manure, as well as some infectious bacteria are inactivated and deodorized through the process of decomposing. Chicken manure organic fertilizer contains medium and trace elements required by plants, beneficial biologically active bacteria and various Enzymes, the life activities of these microorganisms in the soil, can fix nitrogen in the air, loosen the soil, decompose the phosphorus and potassium minerals in the soil ...

AI Technical Summary

Problems solved by technology

[0003] However, livestock manure is prone to produce NH 3 , the current chicken manure organic fertilizer is easy to produce odor under the action of endogenous and exogenous microorganisms during the production process, resulting in unpleasant smell of chicken manure organic fertilizer produced

At the same time, the existing chicken manure organic fertilizer is not fully fermented, and it takes at least two months of fermentation time before it is granulated and packaged for production, which greatly reduces the production efficiency of chicken manure organic fertilizer, and cannot achieve fast and efficient treatment. Fermentation and preparation of chicken manure can not achieve the purpose of saving the production time of chicken manure organic fertilizer, which brings great inconvenience to the production of chicken manure organic fertilizer

[0004] In summary, the problems in the prior art are: (1) livestock manure easily produces NH 3 Various irritating and unpleasant smells, the current chicken manure organic fertilizer is easy to ignore deodorization during the production process, resulting in the production of chicken manure organic fertilizer with an unpleasant smell

[0005] (2) The existing chicken manure organic fertilizer is not fully fermented, the fermentation time is long, and the production efficiency is low. It cannot be fermented and prepared quickly and efficiently chicken manure, which brings great inconvenience to the production of chicken manure organic fertilizer

[0006] (3) Direct use of chicken manure to make organic fertilizers will easily lead to low nutrients, low organic matter content, slow maturation of beneficial microorganisms in the soil, and failure to reflect the efficacy of organic fertilizers in time

It can be said that fundamentally, the generation of odor cannot be suppressed, and secondly, excessive exogenous equipment and substances need to be added, which increases the production cost of the enterprise
