Liquid amino acid fertilizer produced from animal protein and preparation method thereof

Abstract

The invention discloses a liquid amino acid fertilizer produced from animal protein and a preparation method of the liquid amino acid fertilizer. The preparation method comprises the following steps:1) crushing animals and / or animal leftovers to be treated so as to obtain a crushed material; (2) heating, stirring and mixing the crushed animals and / or animal leftovers with alkali liquor at 50-90 DEG C to enable a pH value to be 13 or above, conducting standing for layering after hydrolysis, and taking out a hydrolysate for later use; and 3) regulating the pH value of the hydrolysate to 8-9, regulating a temperature to 60-90 DEG C, and keeping the temperature for 12-72 hours to obtain the amino acid fertilizer. Harmless treatment of animals and / or animal leftovers is achieved in the invention, waste resources are fully utilized, and the virtuous cycle of ecological agriculture is completed while economic benefits are obtained. In the process of preparing the liquid amino acid fertilizer, a leavening agent does not need to be added additionally, and the effects of killing viruses and harmful bacteria and eliminating odor are achieved by adjusting the pH value and temperature in the decomposition process.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a liquid amino acid fertilizer produced from animal protein and a preparation method thereof. Background technique [0002] During the breeding process, some animals die due to climate and environmental factors or infectious diseases. The resulting animal carcasses or the discarded viscera, skin, bones or hooves from slaughtering need to be followed up to avoid impact on the environment or animals. . Existing animal carcass treatment includes deep burial, incineration and high temperature system. Deep burial has problems such as difficulty in choosing a location, contamination of groundwater by landfill fluid, and high cost; residues and non-combustible substances produced by incineration need to be treated separately, and the gas discharged from incineration must comply with environmental protection regulations, otherwise it will easily cause secondary pollution.

Problems solved by technology

However, common bio-organic fertilizers still have some defects: for example, the temperature of composting is low, and harmful bacteria and viruses cannot be completely killed, especially poultry and livestock excrement. Livestock excrement contains a large amount of urine enzymes, which can cause seedling burning. Bacteria and viruses that cannot be completely killed will pollute the environment and spread diseases. Long-term use may even lead to an increase in soil diseases and insect pests, which will seriously affect agricultural production.
