Embodiment 1

[0018] Embodiment 1: A method for preparing an organic fertilizer based on livestock and poultry manure and stalks, comprising the following steps: (1) cutting the corn stalks into small sections with a length of 1 cm to 1.5 cm, and putting the above-mentioned cut corn stalks under anaerobic conditions Pyrolysis at 650°C for 1 hour to obtain the pyrolyzate. After natural cooling, the pyrolyzate was soaked in 30% hydrogen peroxide aqueous solution and incubated at 28°C for 20 days. The pyrolyzate and 30% hydrogen peroxide aqueous solution Incubate according to the mass ratio of 1:15. During the incubation period of the pyrolyzate, replace the 30% hydrogen peroxide aqueous solution every 5 days. After the incubation, rinse the pyrolyzate with deionized water, and grind the pyrolyzate after natural drying. Obtain biochar component A; (2) Grind naturally air-dried chicken manure, pyrolyze the above pulverized chicken manure at 600°C for 1 hour under anaerobic conditions, cool natur...

[0026]Embodiment 2: A method for preparing an organic fertilizer based on livestock and poultry manure and straw, comprising the following steps: (1) cutting the corn straw into small sections with a length of 1 cm to 1.5 cm, and putting the above cut corn straw under anaerobic conditions Pyrolysis at 650°C for 1 hour to obtain the pyrolyzate. After natural cooling, the pyrolyzate was soaked in 30% hydrogen peroxide aqueous solution and incubated at 28°C for 20 days. The pyrolyzate and 30% hydrogen peroxide aqueous solution Incubate according to the mass ratio of 1:20. During the incubation period of the pyrolyzate, replace the 30% hydrogen peroxide aqueous solution every 5 days. After the incubation, rinse the pyrolyzate with deionized water. After the pyrolyzate is naturally dried, grind it Obtain biochar component A; (2) Grind naturally air-dried chicken manure, pyrolyze the above pulverized chicken manure at 600°C for 1 hour under anaerobic conditions, cool naturally, and g...

Embodiment 3

[0034] Embodiment 3: A method for preparing organic fertilizer based on livestock and poultry manure and stalks, comprising the following steps: (1) cutting corn stalks into small sections with a length of 1 cm to 1.5 cm, and putting the above-mentioned cut corn stalks under anaerobic conditions Pyrolysis at 650°C for 1 hour to obtain the pyrolyzate. After natural cooling, the pyrolyzate was soaked in 30% hydrogen peroxide aqueous solution and incubated at 28°C for 20 days. The pyrolyzate and 30% hydrogen peroxide aqueous solution Incubate according to the mass ratio of 1:17. During the incubation period of the pyrolyzate, replace the 30% hydrogen peroxide aqueous solution every 5 days. After the incubation, rinse the pyrolyzate with deionized water, and grind the pyrolyzate after natural drying. Obtain biochar component A; (2) Grind naturally air-dried chicken manure, pyrolyze the above pulverized chicken manure at 600°C for 1 hour under anaerobic conditions, cool naturally, a...

Abstract

The invention belongs to the technical field of organic fertilizers, and particularly relates to a preparation method of an organic fertilizer based on livestock and poultry manure and straw. The preparation method comprises the following steps: preparing a biochar component from corn straw and chicken manure, mixing the biochar component with livestock and poultry manure and straw, and conducting composting to obtain the organic fertilizer based on livestock and poultry manure and straw. The raw materials are easy to obtain, the preparation technology is stable, and the prepared organic fertilizer based on the livestock and poultry manure and the straw can meet the agricultural production requirement and is suitable for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, in particular to a method for preparing organic fertilizers based on livestock manure and straw. Background technique [0002] Organic fertilizers generally refer to organic solid wastes, such as livestock and poultry manure, straw, cakes, agricultural by-products and solid wastes from food processing, which are fermented and completely decomposed by microorganisms. In actual operation, most of the organic fertilizers are prepared with livestock and poultry manure and straw as the main materials. Due to the huge scale of my country's aquaculture industry, the annual production of livestock and poultry manure in my country is also very alarming. The annual production of pig manure alone in my country has reached more than 500 million tons; the production of crop straw in my country is also very high. Traditional crop straw The main treatment method is incineration, which will cause ser...
