Example Embodiment

[0039] Example 1

[0040] Fermented filter cake is used to produce compound microbial fertilizer for aquaculture.

[0041] 1. Sampling: The fermentation filter cake produced during the production of glutamic acid was taken from Henan Lianhua Monosodium Glutamate Co., Ltd.

[0042] 2. Adjust the pH: mix the hydrolyzed filter cake with a moisture content of 40-50% and slaked lime with a moisture content of less than 6% in a ratio of 83:17, and then stack them for 15-20 hours.

[0043] 3. Crushing: When the stacking temperature is less than 35℃, the second crushing is carried out, the fineness of crushing is 40-60 mesh, and the fermented filter cake after crushing is measured. The basic properties are shown in Table 3, and the heavy metals are far lower than the compound microorganisms. The industry standard for fertilizers has not been tested.

[0051] Example 2

[0052] Except for the following process, the others are the same as in Example 1.

[0053] The mixing ratio of fermented filter cake and slaked lime is 4:1.

[0054] Red nonsulfur bacteria (Purple nonsulfur bacteria), Bacillus subtilis (Bacillus subtilis) and Bacillus mucilaginosus (Bacillus mucilaginosus) separately fermented and produced the bacteria liquid according to the ratio of bacterial liquid: rice husk powder = 1:4. The adsorbed single bacterial agent is mixed and crushed according to the ratio of 2.5:1.8:1.

[0055] In the batching step, the added amount of the fermentation filter cake is 150kg, the compound microbial inoculum is 20kg, the urea is 50kg, and the monoammonium phosphate is 30kg.

[0056] Example 3

[0057] Except for the following process, the others are the same as in Example 1.

[0058] The mixing ratio of fermented filter cake and slaked lime is 6:1.

[0059] Purple nonsulfur bacteria (Purple nonsulfur bacteria), Bacillus subtilis (Bacillus subtilis) and Bacillus mucilaginosus (Bacillus mucilaginosus) separately fermented and produced the bacteria liquid according to the ratio of bacterial liquid: rice husk powder = 1:5. The adsorbed single bacterial agent is mixed and crushed according to the ratio of 1.5:2.5:1.

[0060] In the batching step, the added amount of the fermented filter cake is 200kg, the composite microbial inoculum is 30kg, the urea is 15kg, and the monoammonium phosphate is 5kg.

Abstract

The invention provides a production method of compound microbial fertilizer for aquiculture and fertilizer thereof. In the method, a fermentation filter cake in the monosodium glutamate production process serves as raw material; the fermentation filter cake is mixed with hydrated lime and pulverized; then, powdered rice hulls are used for respectively absorbing fermented purple nonsulfur bacteria, bacillus subtilis and Bacillus mucilagimosus krassilm to form single microbial inoculums; the absorbed signal microbial inoculums are mixed according to the ratio of 1.5-2.5:1.5-2.5;1; 5-15% of the mixed microbial inoculums is added into the fermentation filter cake raw materials, inorganic fertilizer is also added, and the mixed microbial inoculum is mixed with the inorganic fertilizer to obtain the compound microbial fertilizer for aquiculture. The effective bacteria number of the compound microbial fertilizer is equal to or more than 2*10/g, total nutrient (N+P2O5+K2O) is 6-25%, and organic matter content is 15%-30%.The production method of the invention has simple technology, and the produced compound microbial fertilizer can effectively improve the quality and the quantity of aquiculture.

Description

technical field [0001] The invention relates to a production method of a compound microbial fertilizer and the compound microbial fertilizer, in particular to a method for producing a compound microbial fertilizer for aquaculture by utilizing a multifunctional microbial compound bacterial agent and a fermentation filter cake for producing glutamic acid The production method and the obtained compound microbial fertilizer. Background technique [0002] With the development of the aquaculture industry and the sharp increase in the price of feed materials, the cost of aquaculture has risen sharply, and the benefits have decreased year by year. In my country, animal protein resources are relatively scarce, and the nutritional requirements of fish for food depend not only on the quantity of protein, but also on its quality, that is, the content and proportion of various amino acids. In aquaculture, although common feed provides certain nutrients for fish growth, it still cannot f...
