preparation example Construction

[0024] The preparation method of the water-soluble biological organic fertilizer of the embodiment of the present invention, the preparation method of this water-soluble biological organic fertilizer comprises the following steps:

[0025] Step 1, adding microbial agent and chlorine-free water to chicken manure, the weight ratio is: chicken manure: microbial agent: chlorine-free water=100:0.4~0.6:300~500;

[0026] Step 2, placing the mixed chicken manure, microbial agent and chlorine-free water in a closed container, and adjusting the internal temperature to maintain at 30-40°C, and fermenting for 7-10 days;

[0027] Step 3, heating the fermentation product to dissolve the organic components in water and kill harmful pathogenic bacteria and insect eggs at the same time;

[0028] Step 4, ultrasonically treating the mixed fermentation product for 6-8 hours to dissolve a large amount of organic matter, centrifuging the mixed fermentation product with a centrifuge, and taking the ...

Embodiment 1

[0053] Take 1000kg of fresh chicken manure with a water content less than 30% in a chicken farm in the suburbs of Nanjing City, Jiangsu Province, add 4000kg of water and 4kg of EM microbial bacterial agent produced by Aimule Environmental Biotechnology (Nanjing) Co., Ltd., stir well, and place it outside Set the jacketed storage tank, then close the opening, adjust the water temperature in the jacket, keep the temperature in the tank at 35-40°C, ferment for 7 days, heat the above fermentation product, and maintain the temperature at 60-65°C for 2 hours , ultrasonic treatment of the above mixture containing more water for 6 hours to dissolve a large amount of organic matter, centrifuge the above mixture with a centrifuge, take the supernatant, and filter the supernatant through sand to obtain 3000-3500kg of yellowish-brown liquid. bottle.

Embodiment 2

[0055] Take 1000kg of fresh chicken manure with a water content less than 30% in a chicken farm in the suburbs of Nanjing City, Jiangsu Province, add 5000kg of water and 5kg of EM microbial bacterial agent produced by Aimule Environmental Biotechnology (Nanjing) Co., Ltd., stir thoroughly, and place outside Set the jacketed storage tank, then close the opening, adjust the water temperature in the jacket, keep the temperature in the tank at 30-35°C, ferment for 10 days, heat the above-mentioned fermentation product, and maintain the temperature at 55-60°C for 3 Hours, ultrasonically treat the above-mentioned mixture containing more water for 8 hours to dissolve a large amount of organic matter, centrifuge the above-mentioned mixture with a centrifuge, take the supernatant, and filter the supernatant through sand to obtain 4000-4500kg of yellow-brown liquid , bottling.

Abstract

The invention discloses a preparation method of a water-soluble biological organic fertilizer. The preparation method comprises steps of: adding a microbial agent and chlorine-free water into chicken manure in a weight ratio of the chicken manure, the microbial agent to the chlorine-free water of 100:0.4-0.6:300-500; adding the mixture of the chicken manure, the microbial agent and the chlorine-free water in a closed container, adjusting the temperature inside to maintain the temperature at 30-40 DEG C, and fermenting for 7-10 days; heating the fermentation product to dissolve organic components in water and to kill pathogenic bacteria and worm eggs; treating the fermentation product by using ultrasonic wave for 6-8 h to dissolve a large amount of organic materials, and subjecting the fermentation mixture to centrifuge separation by a centrifugal machine and taking the supernate; and subjecting the supernate to sand filtration to obtain the water-soluble biological organic liquid fertilizer. In addition, the preparation method is simple and the operation is convenient. The preparation method of the pollution-free water-soluble biological organic fertilizer with low energy consumption is provided.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer preparation, in particular to a preparation method of water-soluble bio-organic fertilizer. Background technique [0002] With the continuous improvement of the intensification of poultry industry in our country, the scale of breeding is increasing day by day, the ensuing negative impact is the increase of poultry manure year by year, improper management of poultry manure stacking and manure flushing, a large amount of pollutants entering the water body, and affecting the rural ecological environment. cause serious impact. [0003] After proper treatment, poultry manure can become a high-quality and efficient bio-organic fertilizer. Its rational use is of great significance and role in reducing the amount of chemical fertilizers and developing organic agriculture. Farmers in our country often collect poultry manure and treat it separately or mix it with forage. Natural composting is ca...
