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...
Embodiment 2
[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...
