Problems solved by technology

[0003] Okra meal is a by-product after ripe okra seeds are oil-pressed, with an organic matter content of about 20%, less than 30%, which does not meet the requirements of the organic fertilizer industry standard (NY525-2002), and is difficult to directly use as a commercial organic fertilizer
[0004] The sour velvet produced after acid removal of cotton seeds has a high organic matter content (generally more than 60%), but the acidity is relatively large (pH<2), and the effective nutrient content of nitrogen, phosphorus and potassium is low (about 1%), and it is difficult to directly use it as an organic fertilizer. use
At present, it is mainly thrown away as garbage, causing serious pollution to the environment

Embodiment 1

[0035] (1) Ammonification: Get 50kg of okra meal and 50kg of sour velvet, mix well; dissolve 10kg of ammonium bicarbonate in 10kg of water, prepare a 50wt% ammonium bicarbonate solution, and evenly spray okra meal and sour velvet On the mixture, seal it with a plastic film for ammoniation after solidification; in summer, the ammoniation time is 7 days;

[0036] (2) Decomposition: 0.4kg of fertile soil microbial bacterial agent mixed with 40kg of water is mixed with 1% solution, for subsequent use; Get 100kg of the ammoniated compound of step (1), add biochar 10kg and mix evenly, then the mixture is tiled on the ground, every Spray 1 layer of fertile soil microbial agent solution at a thickness of 15 cm; pile up to 10 layers, seal with plastic film after stacking, and decompose in summer, and the decomposing time is 20 days;

[0037] (3) neutralization: the material after step (2) is decomposed, add its quality 10% alkaline fertilizer AF (37% of nitrogen, phosphorus and potassi...

Embodiment 2

[0054] (1) Ammonification: Take 50kg of okra meal and 50kg of sour velvet and mix them evenly; dissolve 9.5kg of ammonium bicarbonate in 10kg of water to prepare an ammonium bicarbonate solution, and spray it evenly on the mixture of okra meal and sour velvet. Finally, it is sealed with a plastic film for ammoniation; the length of ammoniation depends on the ambient temperature, and the ammoniation time in winter is 40 days;

[0055] (2) Decomposition: 0.35kg of fertile soil microbial bacterial agent mixed with water 35kg is mixed with 1% solution, for subsequent use; Get 100kg of the ammoniated compound of step (1), add biochar 9.5kg and mix evenly, then the mixture is tiled on the ground, Spray fertile soil microbial agent solution once every 15 cm thick as 1 layer; pile up to 10 layers, seal with plastic film after stacking and decompose, decompose in winter, and decompose for 90 days;

[0056] (3) neutralization: the material after step (2) is decomposed, add its quality 9...

Embodiment 3

[0063] (1) Ammonification: Take 50kg of okra meal and 50kg of sour velvet and mix them evenly; dissolve 10.5kg of ammonium bicarbonate in 10kg of water to make ammonium bicarbonate solution, and spray it evenly on the mixture of okra meal and sour velvet, Finally, it is sealed with a plastic film for ammoniation; for spring ammoniation, the ammoniation time is 21 days;

[0064] (2) Decomposition: 0.4kg of fertile soil microbial bacterial agent mixed with 50kg of water is mixed with 1% solution, for subsequent use; Get 100kg of the ammoniated compound of step (1), add biochar 10.5kg and mix evenly, then the mixture is tiled on the ground, Spray fertile soil microbial agent solution once every 15 cm thick as 1 layer; accumulate to 10 layers, seal with plastic film after stacking and decompose, and decompose in spring for 40 days;

[0065] (3) Neutralization: the material after step (2) is decomposed is added with 10.5% of its quality alkaline fertilizer AF (37% of nitrogen, phos...

Abstract

The invention discloses a method for producing an organic fertilizer by using gumbo meal and acid velvet. The method comprises the following steps: dissolving ammonium hydrogen carbonate in water, then uniformly spraying to a mixture of gumbo meal and acid velvet, stepping compactly, and then sealing with a plastic covering film to perform ammoniation; adding the amide into biological carbon, mixing uniformly, then flatly paving the mixture on the ground surface, and spraying a fertile soil microbial agent solution on each layer once; after multiple layers are stacked, sealing with the plastic covering film to perform decomposition; and adding the decomposed material into an alkaline fertilizer AF and clay, mixing uniformly, then performing granulation, drying, cooling and sieving, and performing measurement packing. The method overcomes outstanding problems of low organic matter content of the gumbo meal and high acidity and low nutrient of the acid velvet, and the produced organic fertilizer can reach a national required organic fertilizer industry standard, contains multiple beneficial bacteria and biological carbons at the same time, and has the functions of improving the utilization ratio of a nitrogen fertilizer, activating soil, bettering soil fertility, enhancing crop disease resistance and promoting plant growth.

Description

technical field [0001] The invention relates to a method for producing organic fertilizer, in particular to a method for producing organic fertilizer by using okra meal and sour velvet, and belongs to the field of fertilizer technology. Background technique [0002] Both okra and cotton belong to Malvaceae crops, and are currently the main economic crops grown in Shandong Province. Converting agricultural wastes into organic fertilizers for fertilizing soil is an effective way to achieve double reduction of pesticides and fertilizers. Organic fertilizer is based on various animal wastes (including animal manure, animal processing waste) and plant residues (cake fertilizer, crop straw, fallen leaves, dead branches, peat, etc.), using physical, chemical, biological or a combination of the three It is formed through certain processing technology (including but not limited to composting, high temperature, anaerobic, etc.) to eliminate harmful substances (pathogens, pest eggs, w...
