Problems solved by technology

An authoritative department estimates that in the next five years, the annual demand for microbial fertilizers will reach 30% of the amount of chemical fertilizers, and the market capacity will reach 42 million tons. However, the current annual production of microbial fertilizers in my country is less than 3 million tons, which is far from being able to meet market needs
Since the compound microbial fertilizer contains live bacteria, the drying during the granulation process has a great impact on the number of live bacteria, and because peat and humic acid are mineral organic raw materials, it is more difficult to dissolve after granulation, and the granulation affects the quality of the product. and effects
However, arable land in many places in the north belongs to machine sowing, and powder products cannot be used, so they are not granulated, which directly affects the mass use and promotion of products
[0006] 3. The granulation rate of disc and drum granulation is low, the particles are irregular, and the surface is not smooth, which affects the appearance quality of the product

Embodiment 1

[0042] 1. Spray and granulate the waste amino acid liquid in the MSG production process into organic granules. The properties of the organic granules are shown in Table 2.

[0043] Table 2: Basic properties of amino acid organic granules

[0044]

[0045] Preparation of liquid inoculum: Bacillus subtilis, Bacillus megaterium and Bacillus mucilagimosus krassilm are separately fermented using fermentation equipment, and the three single bacterial liquids are produced according to 2:1 :1 ratio is mixed, so that the total number of effective viable bacteria of the liquid composite microbial inoculant mixed with the three bacteria liquid after mixing reaches 45.2×10 8 Pcs / g.

[0046] 2. Turn on the mixer, slowly and uniformly add organic granules to make the material flow continuously and uniformly. In the rotating mixer, use a plunger pump to spray the bacteria liquid on the surface of the organic granules at a ratio of 0.6% by weight. Spray 0.6 kg of bacterial liquid into 100 kg of org...

Embodiment 2

[0049] The amino acid waste liquid in the MSG production process is sprayed and granulated, and monoammonium phosphate, borax and humic acid are added in the granulation process.

[0050] 1. Preparation of liquid bacterial agents: Bacillus subtilis and Bacillus megaterium are separately fermented and produced by fermentation equipment, and the two single bacterial liquids are mixed at a ratio of 1:1 to make the two mixed bacteria The total number of effective viable bacteria of the mixed liquid compound microbial inoculants reaches 47.6×10 8 Pcs / g.

[0051] 2. Turn on the mixer, slowly and uniformly add organic granules to make the material flow continuously and uniformly. In the rotating mixer, use a plunger pump to evenly spray the bacteria liquid on the surface of the organic granules at a weight ratio of 0.8% (ie 100 kg Spray 0.8 kg of bacterial liquid in the organic granules).

[0054] The amino acid waste liquid in the MSG production process is sprayed and granulated, and urea, potassium sulfate and ferrous sulfate are added during the granulation process.

[0055] 1. Preparation of liquid bacterial agents: Bacillus subtilis and Bacillus mucilagimosus krassilm are separately fermented using fermentation equipment, and the two single bacterial liquids are mixed in a ratio of 2:1 to make the mixture The total number of effective live bacteria of the liquid composite microbial inoculum mixed with the latter two bacteria liquids reaches 41.6×10 8 Pcs / g.

[0056] 2. Turn on the mixer, slowly and uniformly add organic granules to make the material flow continuously and uniformly. In the rotating mixer, use a plunger pump to evenly spray the bacteria liquid on the surface of the organic granules at a weight ratio of 0.8% (ie 100 kg Spray 0.8 kg of bacterial liquid in the organic granules).

Abstract

The invention provides a method for producing compound microbial fertilizer from amino acid organic granules, in particular to a method for producing compound microbial fertilizer by adopting slurry spraying and granulating processes, comprising the following steps: preparing liquid microbial agent, granulating waste amino acid solution into organic granules, and compounding the organic granules with the liquid compound microbial agent, wherein the liquid compound microbial agent is uniformly absorbed on the surfaces of the amino acid organic granules, and fermentation liquid accounts for 0.5-1.5wt% of the finished product of the compound microbial fertilizer. According to the invention, the normal method for producing the compound microbial fertilizer is improved, a novel method for producing the granular compound microbial fertilizer by two steps of granulating waste amino acid solution into organic granules and absorbing the liquid compound microbial agent by the amino acid organic granules is provided, and the number of viable bacteria in the compound microbial fertilizer is ensured. The production of the compound microbial fertilizer by the slurry spraying and granulating processes breaks through the production of the powdery compound microbial fertilizer by the disc and roller granulating process, thus a good foundation is laid for improving the commodity value, effectiveness and large-area popularization of the compound microbial fertilizer.

Description

Technical field [0001] The invention relates to a method for producing a novel granular compound microbial fertilizer, in particular to a method of using glutamic acid or monosodium glutamate (glutamic acid is the main raw material for producing monosodium glutamate) in the production process of amino acid mother liquor through spray granulation The production method and application of the later amino acid organic granules to produce high-efficiency environment-friendly granular compound microbial fertilizer. Background technique [0002] Due to the application of a large amount of chemical fertilizers, soil compaction, water quality decline, and serious pollution of agricultural products, the entire farmland ecological environment and people's living environment are affected. How to maintain the sustainable development of agriculture in my country has attracted great attention from governments at all levels. Especially after my country’s accession to the WTO, my country’s agricu...
