Problems solved by technology

[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

Embodiment 1

[0038] (1) Harvest the crop stalks within 10 days after the crops are harvested, collect 500 kg of fresh crop stalks, and use an agricultural crop cutter to initially chop the crop stalks so that the length of the chopped straw particles is within 5 cm. Add 50 kg of pure straw to the straw particles. The water is further pulverized with a mixer to form a suspension of crop stalks. The finer the pulverized ground is, the more favorable it is for fermentation. The fiber of crop stalks can reach the degree of breaking the wall.

[0039] (2) Slowly add 0.75 kg of peracetic acid to the crop straw suspension, stirring while adding, so that the peroxyacetic acid and the crop straw suspension are fully mixed.

[0040] (3) Add 3.75kg of urea to the above fermentation system as the nitrogen source for fermentation. When 1.5k sodium percarbonate is added, during the fermentation process, the sodium percarbonate gradually decomposes to generate hydrogen peroxide and sodium carbonate. The role ...

Embodiment 2

[0044] (1) Harvest the crop stalks within 10 days after the crops are harvested, collect 500kg of fresh crop stalks, and use an agricultural crop cutter to initially chop the crop stalks so that the length of the chopped straw particles is within 5cm. Add 100kg of pure straw to the straw particles. The water is further pulverized with a mixer to form a suspension of crop stalks. The finer the pulverized ground is, the more favorable it is for fermentation. The fiber of crop stalks can reach the degree of breaking the wall.

[0045] (2) Slowly add 1.2 kg of peracetic acid to the crop straw suspension, stirring while adding, so that the peroxyacetic acid and the crop straw suspension are fully mixed.

[0046] (3) Add 4.25kg of urea to the above fermentation system as the nitrogen source for fermentation, and add 1.8k sodium percarbonate;

[0047] (4) The mixture obtained in step (3) is driven into a 10m 3 In the fermenter, add 1.5kg of enzyme bacteria, adjust the pH to 7.0~7.5, and the...

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...
