A straw decomposing agent and its production method

A technology of straw decomposing agent and production method, which is applied in the direction of organic fertilizers, etc., and can solve the problem of not fully considering the ability of bacteria to produce enzymes. The bacteria have symbiosis, mutualism, and antagonistic effects on each other. Reasonable, poor stability of decomposing effect, etc., to achieve the effect of extending product shelf life, good promotion and use value, and easy promotion

Problems solved by technology

However, among the currently produced decomposing agent products, there is almost no decomposing agent developed for the condition of returning straw to the field.
Most decomposing agent products are bacterial agent products developed and produced for decomposing livestock and poultry manure or its mixed materials with straw under stacking conditions. There are low bacterial counts and too small enzyme activities in the product, which are difficult to meet the actual market application. At the same time, the strains and strain combinations selected for decomposing agent products are not reasonable, and the enzyme production ability of the strains themselves and the symbiotic, mutualistic, and antagonistic effects of the strains on the product have not been fully considered.
In particular, there are few types of fungi, and the stability of the decomposing effect of straw returning to the field in use is poor

Embodiment 1

[0098] Embodiment 1: A straw decomposing agent, characterized in that: the straw decomposing agent is prepared by mixing Bacillus subtilis, Saccharomyces cerevisiae, Aspergillus oryzae and Aspergillus niger, specifically as follows:

[0099] Step 1), preparing Bacillus subtilis:

[0100] A. Transfer the freeze-dried Bacillus subtilis strains to the pre-prepared test tube slope in a sterile environment, control the temperature at 30-32°C, cultivate for 36-40 hours, and then transfer to the eggplant bottle for 30- After 36 hours, after checking and confirming that there is no miscellaneous bacteria, it is used for fermenter inoculation;

[0101] B, preparation of culture medium material: the culture medium material in the fermenter needs to be proportioned according to the ratio of 0.5g of slag sugar, 0.5g of beef extract, 0.5g of protein jelly and 0.5g of sodium chloride per liter of water, mix and dissolve in water together, transported to the fermenter;

[0102] C. Steriliz...

Embodiment 2

[0130] Embodiment 2: other steps are identical with embodiment 1,

[0131] Step 5) Combine the raw Bacillus subtilis powder, cerevisiae parent powder, Aspergillus oryzae raw powder and Aspergillus niger raw powder obtained in the above steps: mix the raw Bacillus subtilis prepared in the above steps according to the number of grams 3 kilograms of powder, 2 kilograms of Saccharomyces cerevisiae powder, 2 kilograms of Aspergillus oryzae powder and 2 kilograms of Aspergillus niger powder were mixed uniformly to obtain the straw decomposing agent.

Embodiment 3

[0132] Embodiment 3: other steps are identical with embodiment 1,

[0133] Step 5) Combine the raw Bacillus subtilis powder, cerevisiae parent powder, Aspergillus oryzae raw powder and Aspergillus niger raw powder obtained in the above steps: mix the raw Bacillus subtilis prepared in the above steps according to the number of grams 3 kilograms of powder, 3 kilograms of Saccharomyces cerevisiae powder, 1 kilogram of Aspergillus oryzae powder and 2 kilograms of Aspergillus niger powder were uniformly mixed to obtain the straw decomposing agent.

Abstract

The invention relates to a straw decomposing agent produced from raw materials of bacteria and fungi, and a production method thereof. Bacillus subtilis, saccharomyces cerevisiae, Aspergillus oryzae and aspergillus niger are assembled as composite bacteria and are individually cultured through steps of preparation of medium, control of an inoculation amount, a fermentation temperature and a fermentation time, and adjusting of a PH value parameter, concentration and drying. The bacteria are blended and proportioned to prepare into a decomposing agent capable of returning crop straws into field on the spot. The decomposing agent has advantages of strong pertinence, good decomposing effect and stable quality and performance.

Description

technical field [0001] The invention relates to a straw decomposing agent using bacteria and fungi as raw materials and a production method thereof. Bacillus subtilis, S. The temperature and fermentation time are used for separate cultivation, then concentrated and dried, and blended and proportioned to make a decomposing agent product that can return crop straw to the field on the spot. Background technique [0002] The annual output of various straws in our country is as high as more than 50 million tons. In order to deal with these remaining straws, many farmers directly burn the straws produced in the current season in the fields. Straw burning not only destroys the physical and chemical properties of soil, but also seriously wastes resources, pollutes the environment, and destroys ecology. In order to fundamentally solve this contradiction, my country has carried out research on "returning crop straws to the field to increase the content of soil organic matter". Improv...
