preparation example Construction

[0037] The present invention also provides the preparation method of above-mentioned biological organic fertilizer, comprises the following steps:

[0038] (1) choose amino acid fermentation waste liquid, nitrogenous fertilizer, potassium sulfate, monoammonium sulfate, lime powder, ammonium phosphate and humic acid by above-mentioned percentage by weight, and sodium hydroxide regulates pH to be 5.5, makes organic matter content 20%-40%, total The nutrient content is 5%-18%, and it is produced by spray granulation to make fertilizer granules;

[0039] (2) Put the organic fertilizer granules prepared in step (1) into the coating bucket, cool down to 30-60°C, then spray the anti-hardening oil evenly on the surface of the fertilizer granules through the nozzle, and then put the anti-hardening powder and compound microbial bacteria The agent is sprayed on the surface of fertilizer granules through a cage stirring machine to obtain bio-organic fertilizer products.

[0040] In the a...

Embodiment 1

[0043] S1, select 60 parts of amino acid fermentation waste liquid, 15 parts of monoammonium sulfate, 9 parts of potassium sulfate, 5 parts of humic acid, 10 parts of lime powder, adjust pH to 5.5, make organic matter content 30%-35%, total nutrient content 15 %-18%, fertilizer granules are produced by spray granulation;

[0044] S2, put the fertilizer prepared in step S1 into the coating barrel, cool down to about 40°C, then spray 0.5 part of palm oil evenly on the surface of the fertilizer particles through the nozzle, then add 0.2 part of talcum powder and Bacillus subtilis bacterial liquid (200 billion / ml) and 0.1 part of Bacillus megaterium bacteria solution (20 billion / ml) are sprayed on the surface of fertilizer particles to obtain bio-organic fertilizer products.

Embodiment 2

[0046] S1, choose 55 parts of amino acid fermentation waste liquid, 2 parts of urea, 15 parts of monoammonium sulfate, 5 parts of potassium sulfate, 2 parts of ammonium phosphate, 10 parts of humic acid, 10 parts of lime powder, adjust pH to be 5.5, make organic matter content 35 %-40%, the total nutrient content is about 10%-15%, and it is produced by spray granulation to make fertilizer granules;

[0047] S2, the fertilizer that step S1 is made is put into coated barrel, cools down to about 40 ℃, then sprays 0.2 part of palm oil evenly on the surface of fertilizer particles through the nozzle, then 0.5 part of talcum powder and Bacillus subtilis bacterial liquid (200 0.1 part of Bacillus megaterium liquid (20 billion / ml) and 0.1 part of Bacillus jelly-like liquid (10 billion / ml) are sprayed on the surface of fertilizer granules to obtain bio-organic fertilizer products.

Abstract

The invention provides biological organic fertilizer. The biological organic fertilizer comprises 40-60% of amino acid fermentation waste liquid, 0-5% of nitrogen fertilizer, 15-25% of monoammonium sulfate, 5-15% of potassium sulfate, 0-5% of ammonium phosphate, 0.1-0.3% of compound microbial additive, 5-15% of humic acid, 10-20% of lime powder, 0.4-1.0% of hardening preventer. A preparation method of the biological organic fertilizer includes the steps of firstly, selecting the amino acid fermentation waste liquid, the nitrogen fertilizer, the potassium sulfate, the monoammonium sulfate, the lime powder, the ammonium phosphate and the humic acid, regulating pH to 5.5, and performing granulation; secondly placing prepared organic fertilizer granules into a coating barrel, cooling to 30-60 DEG C, spraying hardening-preventing oil on the surfaces of the granules, and spraying hardening-preventing powder and the compound microbial additive onto the surfaces of the fertilizer granules to obtain the biological organic fertilizer. The biological organic fertilizer has the advantages that the fertilizer uses the amino acid fermentation waste liquid as the raw material and is low in organic matter loss, high in strain survival rate and capable of avoiding hardening after being applied. The invention further provides application of the biological organic fertilizer to crops.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a bio-organic fertilizer, a preparation method and the application of the bio-organic fertilizer in crops. Background technique [0002] Bio-organic fertilizer is a new, efficient and safe microbial-organic compound fertilizer formed by combining a variety of beneficial microbial flora and organic fertilizer. It combines the advantages of organic fertilizers and compound microbial fertilizers, can effectively improve fertilizer utilization, regulate plant metabolism, and enhance root activity and nutrient absorption capacity. Therefore, the research, development and rational application of bio-organic fertilizers are not only one of the important measures to obtain high-quality and high-yield crops and improve soil fertility, but also an inevitable trend to protect the ecological environment and promote sustainable agricultural development. [0003] There are man...
