Problems solved by technology

[0002] Organic fertilizers are generally processed from animal and plant wastes and plant residues to eliminate toxic and harmful substances and contain a lot of beneficial materials. However, the production process of organic fertilizers is relatively simple now, and the efficacy of organic fertilizers is poor, and it is difficult for crops to absorb them.
The poor efficacy of pure organic fertilizers is the general nature of organic fertilizers. The nutrient content is low, the fertilizer effect is slow but the fertilizer effect is long, and more advanced technologies cannot fundamentally change this state.
At present, organic fertilizer processing is greatly affected by the natural environment, the fermentation cycle is long, the output is relatively low, the degree of automation is low, and the amount of manual work is large.

Embodiment 1

[0014] A kind of method utilizing pig manure to produce organic fertilizer, comprises the steps:

[0015] (1) Mixing: the pig manure with a water content of 80% is mixed with the bran, the proportion is 120 parts by weight of pig manure, 15 parts by weight of bran, and the C / N ratio of pig manure composting is set to 30, Add a fermenting agent, add 1 part by weight of a fermenting agent for every 6000 parts by weight of pig manure, the fermenting agent is an EM mixed agent, then add plant ash and mix evenly to adjust the water content, so that the water content of the mixture is 60%;

[0016] (2) Primary fermentation: transport the mixed material obtained in step (1) to the fermentation workshop to pile up into strips, each strip has a width of 2.2m and a height of 1.6m, and carries out aerobic fermentation, wherein the summer fermentation time is 20 days, turning once every 3 days; winter fermentation time is 30 days, turning once every 4 days;

[0017] (3) secondary ferment...

Embodiment 2

[0021] A kind of method utilizing pig manure to produce organic fertilizer, comprises the steps:

[0022] (1) Mixing: the pig manure with a water content of 85% is mixed with the bran, the proportion is 140 parts by weight of pig manure, 18 parts by weight of bran, and the C / N ratio of pig manure compost is set to 30, Add fermenting agent, add 1 part by weight of fermenting agent for every 6000 parts by weight of pig manure, said fermenting agent is EM mixed agent, then add plant ash and mix evenly to adjust the water content, so that the water content of the mixture is 65%;

[0023] (2) Primary fermentation: transport the mixed material obtained in step (1) to the fermentation workshop and pile it up into strips. The width of each strip is 2.2m, and the height is 1.8m for aerobic fermentation. The summer fermentation time is 24 days, turning once every 3 days; winter fermentation time is 35 days, turning once every 6 days;

[0024] (3) secondary fermentation: pile up the pro...

Abstract

The invention discloses a method for producing an organic fertilizer from pig manure. The method comprises the following steps: (1) mixing; (2) primary fermentation; (3) secondary fermentation; (4) moisture adjustment; and (5) crushing and sieving. The pig manure undergoes dry-wet separation and microbial dynamic continuous high-temperature fermentation, microbes are used to quickly decompose andconvert substances which can be easily decomposed and easily generate odor in raw materials in the fermentation process, and a high temperature generated in the decomposition process can kill pathogens, eliminate the odor, reduce the water content, reduce the volume and the weight and increase the content of rapidly available nutrients.
