Description
Technical Field
The invention belongs to the technical field of biological organic fertilizers, and particularly relates to a preparation method of a biological organic fertilizer by mixed fermentation of chicken manure and slaughter wastes.
Background
At present: with the rapid development of the large-scale livestock and poultry breeding industry, the livestock and poultry breeding industry is changed from scattered farmer breeding to intensive and industrialized breeding, so that the yield of livestock and poultry manure is increased rapidly. The livestock and poultry manure contains rich organic matters, nitrogen, phosphorus, potassium and other nutrients required by crops, and is a good organic fertilizer; however, the livestock and poultry manure is not suitable to be directly used as an organic fertilizer to be applied to the farmland, otherwise secondary fermentation is caused, oxygen in soil at the root of crops is consumed, high temperature is generated to burn the root systems of the crops, harmful substances with low molecular weight are generated, various pathogenic bacteria are introduced, the environment pollution of the farmland is caused, and even the water pollution is influenced, so that the livestock and poultry manure is required to be decomposed and ripened in the process of applying the livestock and poultry manure as the organic fertilizer. The chicken manure is one of the livestock and poultry manure, and due to the fact that undigested components and harmful flora contained in the chicken manure are high in the livestock and poultry manure, the chicken manure is directly fertilized in soil as an organic fertilizer, the harm caused by the high-concentration organic fertilizer is far higher than that caused by livestock and poultry manure such as pig manure, cow manure and duck manure, and the chicken manure is decomposed when being used as an organic fertilizer raw material.
At present, the rotten treatment of the chicken manure is mostly performed by stacking fermentation or fermentation treatment in a fermentation tank. During the stacking or fermentation process, microorganisms with strong antibacterial activity are formed, and the microorganisms with the antibacterial activity can kill plant pathogenic microorganisms. On the basis, in the process of preparing the organic fertilizer by taking the chicken manure as the organic fertilizer raw material, the organic fertilizer is mostly required to be stacked or subjected to secondary fermentation treatment in a fermentation tank, so that the chicken manure is decomposed and then used as the organic fertilizer for fertilization. However, with the continuous development of agricultural production technology, the living standard of people is continuously improved, the quality requirement of organic fertilizers adopted in the agricultural production process is higher and higher, so that the organic fertilizers with diversified functions are rapidly developed, and researchers adopt slaughter wastes as raw materials to be mixed with chicken manure to prepare the organic fertilizers. However, the livestock and poultry slaughtering waste is generally subjected to simple solid-liquid separation treatment, wherein the solid is buried or incinerated; the liquid after solid-liquid separation is directly discharged into a sewer. The hidden danger is obvious, the landfill is pollution to soil, and if the soil permeates into deep underground, the quality of underground water is endangered; or incineration is extremely serious in atmospheric pollution. The liquid is directly discharged into a sewer, so that the hidden danger is more serious, the liquid is not processed deeply, the oil or blood stain in the liquid can cause the blockage of the sewer, and the peculiar smell is difficult to endure in summer. More importantly, the livestock and poultry slaughter waste belongs to available resources, so that the utilization method of the livestock and poultry slaughter waste is produced.
Through the above analysis, the problems and defects of the prior art are as follows: slaughter waste is generally subjected to simple solid-liquid separation treatment, wherein the solid is buried or burnt; the liquid after solid-liquid separation is directly discharged into a sewer. The hidden danger is obvious, the landfill is pollution to soil, and if the soil permeates into deep underground, the quality of underground water is endangered; or incineration is extremely serious in atmospheric pollution. The liquid is directly discharged into a sewer, so that the hidden danger is more serious, the liquid is not processed deeply, the oil or blood stain in the liquid can cause the blockage of the sewer, and the peculiar smell is difficult to endure in summer.
