Embodiment 1

[0036] 1. Take 200Kg of pig manure and dehydrate until the water content is 70%, mix 400Kg of cow manure, 200Kg of chicken manure with 195Kg of furfural slag, adjust the water content of the mixture to 60% after mixing, then add it to the fermentation tank, add 5Kg of organic materials to decompose The agent is turned over and forwarded by the trough-type turning machine, and the material is forced to be aerated and ventilated through the blower system. Fast decomposing, about 28 days to get aerobic fermentation and decomposing organic raw materials;

[0037] 2. Send the decomposed organic raw materials from the belt conveyor to the double-helix mixer for mixing, and then transport them to the flat belt conveyor for material distribution. The materials are scraped into the feeding bin through the material distributor, granulated by the granulator, and then After being polished into spherical particles by a polishing machine, the particles are transported to the primary dryer, ...

Embodiment 2

[0039] 1. Take 100Kg of pig manure and dehydrate until the water content is 70%, mix 450Kg of cow manure, 150Kg of chicken manure with 130Kg of furfural slag and 20Kg of sawdust, adjust the water content of the mixture to 60% after mixing, then add it to the fermentation tank, add 6Kg Organic material decomposing agent, the material is turned and pushed forward by the trough-type turning machine, forced aeration and ventilation through the blower system, the ceiling adopts a sun shed, the light transmittance of the light-transmitting tile is ≥75%, and the pH is controlled at 7.5-8.5. The mixed material is quickly decomposed, and the aerobic fermentation and decomposed organic raw material can be obtained in about 28 days;

[0040] 2. Stir the decomposed organic raw materials evenly through a mixer, and pass through a 50-100 mesh sieve through a sieving machine. The materials that have not been sieved are returned to the batching system after being crushed, continue to be stirre...

Embodiment 3

[0042] 1. Take 300Kg of pig manure and dehydrate until the water content is 75%, mix 350Kg of cow manure, 100Kg of chicken manure with 200Kg of furfural slag, and 40Kg of rice bran. After mixing, adjust the water content of the mixture to 65%, then add it to the fermentation tank, add 8Kg organic material decomposing agent, through the trough type turning and throwing machine, throwing and pushing the material forward, forced aeration and ventilation through the blower system, the ceiling adopts a sun shed, the light transmittance of the light-transmitting tile is ≥75%, and the pH is controlled at 7.5-8.5 , so that the mixed material is quickly decomposed, and the organic raw material that is aerobically fermented and decomposed is obtained in about 28 days;

[0043] 2. Send the decomposed organic raw materials from the belt conveyor to the double-helix mixer for mixing, and then transport them to the flat belt conveyor for material distribution. The materials are scraped into ...

Abstract

The invention provides a biological organic fertilizer and a preparation method thereof. A biological aerobic composting technology is adopted, a carbon nitrogen ratio, moisture, particle size and other material parameters are adjusted, an organic material decomposition agent is added, and oxygen is supplied in a forced mode, so that the organic materials are fully decomposed, and easily absorbed total nutrition is provided for crops. After functional microbes are added, the utilization rate of the chemical fertilizer is greatly improved, the amount of the chemical fertilizer is reduced by 50 percent, and output reduction is avoided. The content of organic matters of the soil can be improved due to continuous utilization, and the water and fertilizer retaining capacity is improved. The biological organic fertilizer is greatly popularized, the amount of the chemical fertilizer can be greatly reduced, the content of nitrogen, phosphorus and potassium in the soil is increased, and the amount of the chemical fertilizer flowing into the water body is reduced, so that the problem that nitrate in underground water exceeds standard is fundamentally solved. According to the biological organic fertilizer, the problems such as soil hardening and reduction of fertility utilization can be solved, the problem of water and soil pollution caused by application of the chemical fertilizers in a large scale is relieved, and the quality of agricultural products can be improved due to large-area application.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a bio-organic fertilizer and a preparation method thereof. Background technique [0002] China feeds 22% of the world's population with 9% of the world's arable land, and the use of chemical fertilizers is indispensable. But after 30 years of continuous large-scale application, some researchers believe that it will have a negative impact on China's food security. Due to excessive fertilization in some greenhouses and land, the phenomenon of "dead shed" and "jedi" has appeared. At present, the disadvantages caused by the loss of up to 70% of the chemical fertilizers in the soil have been seriously manifested: the eutrophication of the water body has intensified, causing blue-green algae and red tides in rivers, lakes and offshore waters, and the water body is smelly. Improper use of chemical fertilizers is an important cause of water pollution. Many farmers have...
