Embodiment 1

[0026] A kind of organic fertilizer with high content of humic acid prepared by utilizing sulfite process sugar factory filter mud, comprising the following steps:

[0027] Step A: Screening of fermentation strains, select Bacillus subtilis (No. ACCC11060), Bacillus megaterium (No. ACCC10010) and jelly-like Bacillus (also known as silicate bacteria) (Bacillus mucilaeinosus, No. ACCC11103 ) mixed as fermentation strains, these three strains were purchased from the National Culture Collection Center, and the mass ratio of the three was 1:1:1, that is, each accounted for one-third.

[0028] Step B: Use the screened fermentation strains for the production of koji, operate under sterile conditions, inoculate and cultivate the purified strains, and the obtained strains are first-class seeds; shaker amplification, the obtained first-class seeds Inoculate into a triangular flask, cultivate and amplify the number of bacteria, and cultivate for 3-5 days. The cultured strain is the secon...

Embodiment 2

[0035] On the basis of embodiment 1, the bacterium koji of this example is made up of Bacillus subtilis, gigantic bacillus and jelly-like bacillus, and the amount of bacterium koji is 3.0 kilograms of bacterium koji per ton of sulfite sugar factory filter mud, to obtain organic Fat B.

[0036] Contrast test adopts the general fungus koji on the market, and general bacterium koji consumption is 5.0 kilograms of bacterium koji per ton of sulphite sugar factory filter mud, obtains conventional organic fertilizer; Described general bacterium koji is made of yeast and Bacillus subtilis (Bacillus subtilis, No. ACCC11068) composition.

[0037] The organic fertilizer B was compared with the conventional organic fertilizer, and the results are shown in Table 2. From the comparison of the data in Table 2, it can be seen that the humic acid content of organic fertilizer B is 30.1%, and the conventional organic fertilizer is only 16.8%. Organic fertilizer B is 13.3% higher than conventio...

Embodiment 3

[0041] On the basis of Example 1, the amount of bacterium koji used in this example is 4.5 kilograms of bacterium koji for every ton of sulfitation sugar factory filter mud to obtain organic fertilizer C.

[0042] Contrast test adopts the general fungus koji on the market, and general bacterium koji consumption is 5.0 kilograms of bacterium koji per ton of sulphite sugar factory filter mud, obtains conventional organic fertilizer; Described general bacterium koji is made of yeast and Bacillus subtilis (Bacillus subtilis, No. ACCC11068) composition.

[0043]The organic fertilizer C was compared with the conventional organic fertilizer, and the results are shown in Table 3. From the comparison of the data in Table 3, it can be seen that the humic acid content of organic fertilizer C is 31.2%, and that of conventional organic fertilizer is only 16.8%. Organic fertilizer C is 14.4% higher than conventional organic fertilizer, and has a higher humic acid conversion rate .

Abstract

The invention provides an organic fertilizer with high humic acid content and a preparation method thereof. The organic fertilizer with high humic acid content is prepared by the following method: prepare fermentation strains, and the fermentation strains include Bacillus subtilis, Bacillus megaterium and bacillus jelly-like; making koji from the fermented strains; mixing the sulphite sugar factory filter mud with the koji, and fermenting to obtain an organic fertilizer with high humic acid content. Compared with traditional organic fertilizers, the organic fertilizer obtained by the technical scheme of the present invention has a higher humic acid conversion rate, and the humic acid content of the organic fertilizer is higher; The resource utilization of the sugar industry has solved the environmental pollution problem of the sulfite sugar factory filter mud that has been plagued by the sugar factory, turning waste into wealth, fertilizing the soil, increasing production and sugar, realizing clean production, protecting the environment, and promoting sugar production. The industry continues to develop.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to an organic fertilizer with high humic acid content and a preparation method thereof. Background technique [0002] Guangxi is the largest sugar industry base in my country, and its cane sugar production accounts for about 70% of the country's total. The sugar cane industry is an important economic pillar in Guangxi. Each ton of sugar cane produces about 3% of filter mud during the sugar extraction process. Sulfurized sugar-sulfurous acid clarification technology is a typical cleaning and decolorization method of cane juice and syrup in the white granulated sugar production industry. Since this method has the characteristics of less equipment, relatively simple process flow, and convenient management, this clarification Technology has been widely used in my country's sugar industry. However, due to various reasons, the filter mud of sulphite sugar factory has been discharged randomly for ...
