Embodiment 1

[0023] A preparation method for fermenting and decomposing organic fertilizer by microbial bacterial agent, comprising the steps of:

[0024] S1. After cutting / cutting the residues of traditional Chinese medicine and / garden waste, put them in the steam explosion tank, first feed nitrogen gas until the pressure in the steam explosion tank is 1 MPa, and blast for 15 minutes; then quickly inject steam into the steam explosion tank The internal pressure is 2.5MPa, steam explosion treatment for 5min, and drying to obtain a powder with a particle size of about 200 mesh. After drying at a high temperature at 300°C until the water content is less than 1%, the obtained chicken and duck manure powder (particle size at 100 mesh or so) adjust the carbon-nitrogen ratio to 20:1, the water content is 60%, and the mixture is obtained;

[0025] S2. Preparation of fermented bacterial liquid with compound bacterial agent, fructooligosaccharide, wheat bran powder, and water as raw materials; wher...

Embodiment 2

[0029] A preparation method for fermenting and decomposing organic fertilizer by microbial bacterial agent, comprising the steps of:

[0030] S1. After cutting / cutting the Chinese medicine residue and / garden waste into pieces, put them in the steam explosion tank, first pass nitrogen into the steam explosion tank until the pressure in the steam explosion tank is 2.5MPa, and blast for 10 minutes; then quickly inject steam into the steam explosion tank The internal pressure is 3.5 MPa, steam explosion treatment for 3 minutes, and drying to obtain a powder with a particle size of about 200 mesh. After drying at a high temperature at 300°C until the water content is less than 1%, the obtained chicken and duck manure powder is ground (with a particle size of About 100 mesh) adjust the carbon-nitrogen ratio to 30:1, the water content is 50%%, and the mixture is obtained;

Abstract

The invention relates to the field of organic fertilizers, in particular to a preparation method of a microbial agent fermented and decomposed organic fertilizer, which comprises the following steps: S1, respectively crushing traditional Chinese medicine residues and / or garden wastes to 200 meshes, and regulating the carbon nitrogen ratio to 20: 1-30: 1 and the water content to 50-60% by using chicken and duck manure to obtain a mixture; s2, preparing a zymophyte solution by taking a complex microbial inoculant, fructo-oligosaccharide, wheat bran powder and water as raw materials; s3, uniformly mixing and stirring the mixture particles and a zymophyte solution, and granulating to obtain fermented particles; and S4, spreading the fermented particles on the ground, covering a film, and fermenting for about 25 days to obtain the organic fertilizer particles. According to the invention, the decomposition speed of compost can be accelerated, sufficient decomposition of the organic fertilizer can be realized in 25 days, and the obtained organic fertilizer can provide efficient and lasting fertility for crops and can also improve the soil environment.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a preparation method for fermenting decomposed organic fertilizers with microbial agents. Background technique [0002] At present, the fertilizers on the market are divided into inorganic fertilizers, organic fertilizers and biological fertilizers in terms of nature. Among them, organic fertilizer is a type of fertilizer rich in nutrients fermented from agricultural waste, poultry manure, and urban domestic waste. It is not only non-polluting to the soil, but also has relatively complete nutrients. The soil has a certain improvement effect. However, the current organic fertilizers also have the disadvantages of low nutrient content, not easy to decompose, and cannot meet the requirements of high crop yield in time. Contents of the invention [0003] In order to solve the above problems, the present invention provides a preparation method of fermented and decomposed organic...
