Method for preparing organic fertilizer by aerobic fermentation of microorganisms

Abstract

The invention discloses an organic fertilizer prepared by aerobic fermentation of microorganisms. A preparation method comprises steps: collecting fresh crop straws, and further crushing the collectedcrop straws into a crop straw suspension; adding peracetic acid into the crop straw suspension, and fully stirring; and carrying out aerobic fermentation by using enzyme microorganisms, adding functional zymophyte, and carrying out facultative fermentation for 2-5 days. The method can fully realize cyclic utilization of data, use microorganisms for aerobic fermentation, can rapidly catalyze and decompose straws, decompose the straws into nutritional ingredients for plants and beneficial organisms in a short time, reduce the use amount of pesticides and chemical fertilizers, develop natural ecological agriculture, and reduce environmental pollution.

Description

Technical field [0001] The invention relates to the field of fertilizer production, in particular to a method for preparing organic fertilizer by aerobic fermentation of microorganisms. Background technique [0002] Almost all beneficial bacteria in agriculture are saprophytic organisms, especially aerobic microorganisms. Among them, aerobic bacteria, actinomycetes, and fungi are beneficial to agriculture. The aerobic fermentation straw compost organic fertilizer is used for Promote the reproduction of beneficial microorganisms in the soil. Beneficial microorganisms can improve the soil ecological environment, inhibit the reproduction and harm of harmful microorganisms, decompose harmful chemical substances (including pesticide residues, chemical pollution), and provide necessary nutrients for crop growth. In the long-term application of chemical fertilizers and pesticides, no organic fertilizers, soils with extremely poor biological properties, applying biological fertilizers t...

[0008] (3) The fermented organic fertilizer is acidic, which generates acidic humus in the soil, lowers the ground temperature, and deteriorates the soil ecosystem. At the same time, the nutrients contained in it are better utilized except for nitrogen and potassium, and other elements such as phosphorus and magnesium are significantly reduced. Fertilizer effect, the overall effect of soil improvement is not great

[0009] (4) Long-term use will acidify the soil, resulting in the release of heavy metals in the soil, polluting the soil and agricultural products
