A kind of chicken manure biological organic fertilizer and preparation method thereof

Abstract

The invention belongs to the field of biotechnology, and relates to a chicken manure bio-organic fertilizer and a preparation method thereof. Compost raw materials include fresh chicken manure, dried distiller's grains, straw and compound composting bacteria; the compound composting bacteria are obtained from fermentation medium cultured with dried distiller's grains enzymatic hydrolyzate; Dried distiller's grains solution is obtained; the amount of dried distiller's grains is 5% to 15% of the mass of fresh chicken manure. The preparation of chicken manure bio-organic fertilizer is as follows: fresh chicken manure, dried distiller's grains and straw are mixed, the C / N is adjusted to 20-24, the moisture content is 50%-60%, and the composting bacteria are mixed according to 0.1%-0.5% of the total mass of the pile. After preparation, compost and ferment for 6-20 days. The invention uses dried distiller's grains as nutrients, on the one hand, releases a large amount of amino acids as nutrient components of the medium, and on the other hand, as compost auxiliary materials, effectively reducing the difference in nutritional environment, simple production process, short production cycle, and higher quality bio-organic fertilizer .

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a chicken manure biological organic fertilizer and a preparation method thereof. Background technique [0002] With the intensive and large-scale development of my country's chicken industry, a large amount of manure will be formed. Nitrogen, phosphorus, heavy metal elements, residual antibiotics, pathogenic microorganisms and insect eggs in chicken manure will directly enter the farmland soil water body without treatment. , which not only seriously pollutes the environment, but also wastes nutrient resources, which is not conducive to the sustainable development of industrial economy and environment. In fact, the use of livestock and poultry manure composting and fermentation to produce organic fertilizer is one of the important ways to realize the harmless utilization and resource utilization of chicken manure. The organic matter in chicken manure is degraded by function...
