Production method of bovine bone amino acid organic fertilizer

Abstract

The invention discloses a production method of a bovine bone amino acid organic fertilizer, which comprises the following steps: S1, pouring a bovine bone raw material into a cooking container, addinga certain amount of water, pressurizing the container to achieve a pressure of 0.1 MPa, and cooking for 2-5 h; and S2, carrying out percolation type separation on the cooked material, and carrying out solid-liquid separation. According to the method, the raw material is subjected to high-temperature pressurized sterilization, different raw material components are separated after cooking and are correspondingly decomposed and utilized, and livestock bone slaughter waste such as bovine bones is rapidly, efficiently and harmlessly treated. Amino acid in sclerotin is decomposed by an enzymolysismethod, organic calcium and other trace elements are separated, and the decomposed amino acid can be directly put into agricultural production for use. The treated waste residues are subjected to composting treatment, residual organic substances are further decomposed and become an excellent carrier of a microbial agent by virtue of a loose cavity structure of the waste residues, and meanwhile, the waste residues are used as an organic fertilizer granulation hardening agent and a propping agent to immobilize soil nutrients, so that the purpose of slowly releasing the nutrients is achieved, andresource utilization is realized to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of bovine bone treatment, in particular to a method for producing bovine bone amino acid organic fertilizer. Background technique [0002] my country is a large animal husbandry country. The total production and consumption of livestock and poultry are in the forefront of the world. The resources of livestock and poultry bones are very rich, but the comprehensive utilization rate is low, of which the proportion of deep processing, high value and resource utilization is less than 3%. Resources are discarded at will, resulting in waste of resources and environmental pollution. Beef bones account for about 20% to 40% of the body weight of beef cattle. The protein content of fresh beef bone raw materials is about 14.27%, fat 28.55%, calcium 14.01%, water 20.9%, protein, calcium, phosphorus, vitamins, trace elements and other substances. [0003] Among them, bovine bone is more difficult to handle than other bone...
