Embodiment 1

[0052] Step ①, material mixing

[0053] The zeolite is crushed into zeolite powder with a particle size of 0.5mm, and the litter broiler manure (moisture content is 45%), breeder manure (moisture content is 75%) and zeolite powder are mixed evenly according to the weight ratio of 60:35:4, The pH of the mixture was 5.5, and the moisture content of the mixture was 60%.

[0054]Step ②, aerobic fermentation

[0055] The mixture and the microbial agent are piled up (stacks with a height of 1.2m and a width of 2m). After fermentation for 2 to 3 days, when the temperature of the pile rises to 65°C, turn the pile with a turning machine. When the temperature of the pile drops to 30 ℃, the aerobic fermentation ends, and the aerobic fermentation time is 9 to 12 days.

[0056] The weight of the microbial agent is 0.5% of the mixture. The colony-forming unit ratio of Aspergillus oryzae, high-temperature-resistant Bacillus subtilis and yeast in the microbial agent is 1:1:2, and the bacter...

[0062] Step ①, material mixing

[0063] The zeolite is crushed into zeolite powder with a particle size of 0.8mm, and the litter broiler manure (moisture content is 42%), breeder and laying hen manure (moisture content is 70%) and zeolite powder are in a weight ratio of 65:30:5.5 Mix well, the pH of the mixture is 6.5, and the moisture content of the mixture is 55%.

[0064] Step ②, aerobic fermentation

[0065] The mixture and the microbial agent are piled up (stacks with a height of 1.4m and a width of 2.5m). At 40°C, the aerobic fermentation ends, and the aerobic fermentation time is 9 to 12 days.

[0066] The weight of the microbial agent is 0.5% of the mixture. The colony-forming unit ratio of Aspergillus oryzae, high-temperature-resistant Bacillus subtilis and yeast in the microbial agent is 1:1:2, and the bacterial content in the microbial agent is greater than 0.5×10 6 pcs / g.

Embodiment 3

[0072] Step ①, material mixing

[0073] The zeolite is crushed into zeolite powder with a particle size of 1.2mm, and the litter broiler manure (moisture content is 42%), laying hen manure (moisture content is 70%) and zeolite powder are mixed evenly according to the weight ratio of 70:25:7, The pH of the mixture was 7.0, and the moisture content of the mixture was 50%.

[0074] Step ②, aerobic fermentation

[0075] The mixture and the microbial agent are piled up (stacks with a height of 1.5m and a width of 2.2m). At 35°C, the aerobic fermentation ends, and the aerobic fermentation time is 9 to 12 days.

Abstract

The invention relates to an organic fertilizer and a production method of the organic fertilizer, in particular to a method for utilizing chicken manure to produce the organic fertilizer. The method comprises the following steps: uniformly mixing padding, broiler chicken excrement, breeding hen and/or laying hen excrement and zeolite to obtain a mixture; inoculating a microbial agent which is used for sufficiently curing the manure to the mixture, carrying out aerobic fermentation under the intermittent turning condition, wherein the microbial agent at least comprises aspergillus oryzae, high temperature resistant bacillus subtilis and saccharomycetes; piling and ageing the material after aerobic fermentation. The method aims at the characteristics of excrement of laying hen and breeding chicken, and flatly raised broiler chicken excrement, mixes the two kinds of chicken manure with different properties to meet requirements of the fermented material to carbon nitrogen ratio and moisture, and reduces the production cost. The chicken manure which possibly pollutes the environment can be converted to the organic fertilizer with large processing amount, so that the pollution problem of the chicken manure is solved. The produced organic fertilizer can be widely applied to organic crop planting, obviously improve the quality of agricultural products, and effectively improve the soil structure.

Description

[0001] technical field [0002] The invention relates to an organic fertilizer and a production method thereof, in particular to a method for producing organic fertilizer by utilizing chicken manure. Background technique [0003] The rapid development of my country's large-scale chicken industry has brought a surprising amount of chicken manure. If chicken manure can't be used as a harmless resource, it will seriously pollute the ecological environment, which will seriously affect the healthy development of the breeding industry. Chicken intestines are short and feed digestibility is low, so chicken manure is rich in organic matter and high in N, P, K and trace elements. It is a good fertilizer raw material, but chicken manure needs to be thoroughly decomposed before it can be applied. Otherwise, the phenomenon of burning seedlings will occur when it is applied in the field. [0004] The methods of harmlessly treating chicken manure to produce organic fertilizer mainly inc...
