Abstract

An organic fertilizer production method is characterized by comprising the steps of: (1) preparation: mixing the following raw materials in parts by weight on the basis of per ton: 5 parts of cow dung, 3 parts of baked duck, and 2 parts of mushroom dreg; (2) piling: piling the raw materials obtained from step (1), wherein each pile is 1m-3m in width and 0.8m-1.2m in height; (3) addition of microbial inoculums: evenly mixing the microbial inoculums with mushroom dreg according to the proportion of 1:4, and then distributing the mixture on the surfaces of the piles; (4) fermentation: covering coverage on the piles, fermenting the interior of the piles through the microbial inoculums, automatically raising the temperature to 60 DEG C for 15 days; (5) sieving: sieving the organic fertilizer obtained from step (4); (6) pelletizing: pelletizing the organic fertilizer obtained from step (5); and (7) drying, cooling and packaging: drying the particles until the standard of the organic fertilizer achieves 20% below, cooling and packing the dried fertilizer particles. The raw materials can be fully fermented by controlling the temperature and humidity of the raw materials and the size of the microbial inoculums so as to improve the fertility of the organic fertilizer.

Description

The organic fertilizer production method

Technical field

The present invention relates to the chemical fertilizers production field.

Background technology

At present in the organic fertilizer production to temperature, humidity and the improper use of microbial inoculum consumption size of raw material, raw material is fully fermented or the microbial inoculum consumption is excessive makes it waste.

Summary of the invention

For raw material fully being fermented and reducing bacterium Liu's waste.

Purpose of the present invention is come specific implementation by the following technical programs:

A kind of organic fertilizer production method is characterized in that, comprising:

1) proportioning, raw material per ton mixes with the ratio of 5 parts of cow dungs, 3 parts of duck bakings, 2 parts of bacterium slags;

2) bar heap, the raw material that step 1) is obtained carries out the bar heap, and bar is piled wide 1m-3m, high 0.8m-1.2m;

3) add microbial inoculum, microbial inoculum to mix with the ratio of bacterium slag ratio example 1:4, is distributed in bar with mixture after mixing and piles the surface;

4) fermentation covers coverture at the bar heap, is heated up voluntarily by bacteria fermentation in bar heap inside, and temperature kept 15 days after being raised to 60 degree;

5) sub-sieve, the fertilizer that step 4) is obtained carries out sub-sieve;

6) granulation, the fertilizer granulation that step 5) is obtained;

7) oven dry, cooling, packing dry the particle of making to fertilizer standard below 20%, and the granular organic fertilizer of oven dry is packed through after cooling.

Further, the described temperature of step 4) is turned over the bar heap 3-4 time after being raised to 60 degree.

Further, humidity remained on 70%-80% after the described temperature of step 4) was raised to 60 degree.

Further, the described sub-sieve of step 5) is selected 70-80 purpose screen cloth.

The present invention passes through the control of the temperature humidity of raw material and the size of microbial inoculum amount, raw material is fully fermented improve the fertility of fertilizer.

Embodiment

The described a kind of organic fertilizer production method of the embodiment of the invention is characterized in that, comprising:

2) bar heap, the raw material that step 1) is obtained carries out the bar heap, and bar is piled wide 2m, high 1m;

4) fermentation covers coverture at the bar heap, is heated up voluntarily by bacteria fermentation in bar heap inside, and humidity remained on 70% after temperature was raised to 60 degree, kept 15 days, turned over the bar heap 3 times;

5) sub-sieve, the fertilizer that step 4) is obtained carries out sub-sieve with 80 purpose screen clothes;

6) granulation, the fertilizer granulation that step 5) is obtained;

Claims

1. an organic fertilizer production method is characterized in that, comprising:

5) sub-sieve, the fertilizer that step 4) is obtained carries out sub-sieve;
