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

[0042] Production of compound microbial fertilizers from fermented filter cakes.

[0043] 1. Sampling: The fermentation filter cake produced in the glutamic acid production process was taken from Henan Lianhua MSG Co., Ltd.

[0044] 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.

[0045] 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

[0054] Except following technology, other is with embodiment 1.

[0055] The mixing ratio of fermented filter cake and slaked lime is 4:1.

[0056] The bacterial liquid produced by separate fermentation of Purple nonsulfur bacteria, Bacillus subtilis and Bacillus mucilaginosus is adsorbed at the ratio of bacterial liquid: peat = 1:4. The single bacterial agent after adsorption was mixed and pulverized according to the ratio of 2.5:1.8:1.

[0057] 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

[0059] Except following technology, other is with embodiment 1.

[0060] The mixing ratio of fermented filter cake and slaked lime is 6:1.

[0061] Bacillus liquid produced by separate fermentation of Purple nonsulfur bacteria, Bacillus subtilis and Bacillus mucilaginosus is adsorbed at the ratio of bacterial liquid:peat=1:5. The single bacterial agent after adsorption was mixed and pulverized according to the ratio of 1.5:2.5:1.

[0062] 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 composite microbial fertilizer using fermented filter cakes as a medium and a production method thereof. In the method, fermented filter cakes from the production of gourmet powder are used as raw materials and are mixed with slaked lime, the mixture is ground, the fermenting photosynthetic bacteria, bacillus subtilis and bacillus mucilagimosus krassilm are absorbed by turf respectively, the separately absorbed single bacteria are mixed in a ratio of 1.5-2.5:1.5-2.5:1, the mixed bacterial are added into the fermented filter cake raw material in a ratio of 5 to 15 percent, an inorganic fertilizer is added, the mixture is mixed, and thus, the composite microbial fertilizer is obtained. The composite microbial fertilizer can be used for fertilizing farm lands as well as aquiculture and can improve the yield and quality of aquiculture effectively.

Description

technical field [0001] The invention relates to a compound microbial fertilizer and a production method thereof, in particular to a compound microbial fertilizer produced by using a multifunctional microbial compound bacterial agent and a glutamic acid-producing fermentation filter cake and a production method thereof. 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 fully meet the growth requirements of fish. Reasonable fertilization can promote the growth of plankton i...
