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 (Bacillus subtilis, number ACCC11060), Bacillus megaterium (Bacillus megaterium, number ACCC10010) and jelly-like Bacillus (also known as silicate bacteria) (Bacillus mucilaeinosus, number ACCC11103) mixed as Fermentation strains, these three strains are purchased from the National Culture Collection Center, and the mass ratio of the three is 1:1:1, that is, each accounts 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 f...

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 bacterium koji on the market, and general bacterium koji dosage is 5.0 kilograms of bacterium koji per ton of sulfitation sugar factory filter mud, obtains conventional organic fertilizer; 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 conventional organic fertilizer, and has a higher humic acid conversion rate .

[0038] Table 2 Compar...

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 used for per ton of sulfitic sugar factory filter mud to obtain organic fertilizer C.

[0042] Contrast test adopts the general bacterium koji on the market, and general bacterium koji dosage is 5.0 kilograms of bacterium koji per ton of sulfitation sugar factory filter mud, obtains conventional organic fertilizer; 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 .

[0044] Table 3 Comparison table of humic acid content between organic fertilizer C and conventional ...

Abstract

The invention provides an organic fertilizer with high humic acid content and a preparation method thereof. The preparation method of the organic fertilizer with high humic acid content includes the following steps: preparing fermentative bacteria, wherein the fermentative bacteria include bacillus subtilis, bacillus megaterium and bacillus mucilaginosus; making the fermentative bacteria into fermentation microbial agent; filtering mud in a sugarhouse through a sulfurous method, and mixing with the fermentation microbial agent for fermentation to obtain the organic fertilizer with high humic acid content. Compared with the conventional organic fertilizer, the organic fertilizer obtained through the technical scheme provided by the invention is higher in humic acid conversion rate and humic acid content; the sulfurous method is fully utilized to filter mud in the sugarhouse, and resource utilization is realized in the cane sugar industry, and the problem of environment pollution troubling the sugarhouse, caused by the mud filtration with the sulfurous method in the sugarhouse is solved; wastes are turned to treasures, soil productivity is increased, the sugar yield is increased, cleaner production is realized, the environment is protected, and the sustainable development of the sugar industry is promoted.

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 ...
