Aerobic-fermentation efficient organic fertilizer and preparation method thereof

Abstract

Solid wastes discharged by some large culturing farms at present have threatened the surrounding environment, solid organic wastes are resources, inappropriate treatment causes the environmental pollution, and the low-cost conversion of the wastes to organic fertilizers for the fertility betterment and nutrition provision of mulch through an economic means solves the environmental pollution problem, provides a good product raw material for the saline-alkali soil improvement, the organic agriculture and the green agriculture, and generates a good economic benefit. The method provides a method for preparing an efficient organic fertilizer through the aerobic fermentation of organic solid wastes comprising domestic fungus dregs, animal night soil and the like. The preparation method comprises the steps of raw material blending, composite inoculant addition, aerobic fermentation and organic fertilizer preparation. The preparation method is characterized in that the preparation method concretely comprises the following steps: uniformly mixing pig manure, chicken manure, domestic fungus dregs, coconut chuff and crushed straws according to a certain ratio, adding an aerobic-fermentation composite inoculant selected through optimization test to the above obtained mixture, and carrying out aerobic fermentation to prepare the organic fertilizer.

Description

Technical field [0001] The invention relates to the field of fertilizer production and solid waste treatment. Background technique [0002] In recent years, the state has actively supported policies and financial resources to build a large number of large and medium-sized livestock and poultry farms to replace small-scale free-range breeding with intensive breeding. This not only ensures a sufficient supply of livestock and poultry products in our country, but also effectively improves the living environment of our new socialist countryside. However, the pollution of the aquaculture industry in my country has changed from "non-point source pollution" to "point source pollution". "Point source pollution" seems easier to monitor, but the current average daily waste discharge of large farms around modern cities is huge , Which far exceeds the absorption and carrying capacity of the surrounding environment, posing a serious threat to the safety of the surrounding environment, causing...
