Preparing and using methods of composting fermentation strain

Abstract

The invention relates to a preparing method of a composting fermentation strain. Preparing and using methods comprise the following steps: collecting microorganisms in an environment; inoculating a selective medium, which takes a rice leachate, sugar, milk, inorganic salt, bran, rice husks, composting raw material chippings as major ingredients, with the microorganisms, and implementing directional screening and propagation, so that the compound strain which is applicable to composting is obtained; forming a trapezoid material pile by virtue of such composting raw materials as crop straws, vegetable leavings, excrements of livestock, kitchen waste and the like; regulating the trapezoid material pile to a proper water content; uniformly inoculating the trapezoid material pile with the composting fermentation strain; turning the pile for several times and implementing aerobic fermentation until composting raw materials become soft, the volume of the composting raw materials is diminished, the morphology of the raw materials cannot be observed obviously, and the composting raw materials are neutral or faintly alkaline and free from odor, so that composting is completed. With the application of the methods, composting time can be obviously shortened, the thorough decomposition of the composting raw materials can be accelerated and a more thorough fermentation reaction can be guaranteed.

Description

technical field [0001] The invention relates to the field of composting fermentation, in particular to a method for making and using composting fermentation strains. Background technique [0002] my country is a large agricultural country, and the amount and variety of wastes such as crop stalks, vegetable tails, and livestock and poultry manure produced in the process of agricultural production are huge. In addition to being rich in carbohydrates, these wastes also contain essential or beneficial elements for plant growth such as nitrogen, phosphorus, potassium, calcium, magnesium, and silicon. Utilizing it as fertilizer and returning it to farmland can not only improve the soil and increase soil nutrients, but also reduce environmental pollution, which is an important technical way to promote clean agricultural production. [0003] The fertilization and utilization of agricultural waste mainly includes returning compost to the field, returning to the field with in-situ bi...

Problems solved by technology

[0004] Traditional soil method composting mainly relies on the microorganisms carried in natural materials such as manure bottom, humus and silt of old compost for fermentation. The biomass of the initial inoculation of the bacteria is insufficient, and the ability to decompose organic matter is not strong, and the composting time is long Produce a large amount of NH 3 、H 2 Volatile substances such as S, amines, and aldehydes have a large loss of fertilizer efficiency, and the risk of secondary pollution caused by waste gas, sewage, and residues is high
