Problems solved by technology

[0006] Glutamic acid is mainly used to produce monosodium glutamate. Glutamic acid is made from rice and wheat starch through microbial fermentation, extraction and refining. The solid culture material produced in the fermentation process of glutamic acid production is filtered and obtained by fermentation. Due to its strong acidity, the cake cannot be effectively used, resulting in a large backlog. If it is lost with water or discarded in the soil, it will cause water quality and soil acidification and cause pollution. The country strictly prohibits its discharge

Embodiment 1

[0040] Production of complex microbial fertilizers for aquaculture from fermented filter cakes.

[0041] 1. Sampling: The fermentation filter cake produced in the glutamic acid production process was taken from Henan Lianhua MSG Co., Ltd.

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

[0043] 3. Crushing: When the stacking temperature is less than 35°C, carry out the second crushing, the crushing fineness is 40-60 mesh, and measure the fermented filter cake after crushing. The basic properties are shown in Table 3, and the heavy metals are far lower than those of compound microorganisms. Industry standard for fertilizers, no determination was performed.

Embodiment 2

[0052] Except following technology, other is with embodiment 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 gum peptone-like Bacillus (Bacillus mucilaginosus) produced by separate fermentation are adsorbed according to the ratio of bacteria liquid: rice husk powder = 1:4. The single bacterial agent after adsorption was mixed and pulverized according to the ratio of 2.5:1.8:1.

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

Embodiment 3

[0057] Except following technology, other is with embodiment 1.

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

[0059] Red nonsulfur bacteria (Purple nonsulfur bacteria), Bacillus subtilis (Bacillus subtilis) and gum peptone-like Bacillus (Bacillus mucilaginosus) produced by separate fermentation are adsorbed according to the ratio of bacteria liquid: rice husk powder = 1:5. The single bacterial agent after adsorption was mixed and pulverized according to the ratio of 1.5:2.5:1.

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

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...
