Problems solved by technology

[0004] At present, the bio-organic fertilizers on the market are mainly made of livestock and poultry manure and plant stalks, which are fermented and decomposed. The bio-organic fertilizers produced from these raw materials are slow to ferment and decompose, cause heavy air pollution, occupy a large area, and are labor-intensive and time-consuming. Carry out large-scale batch production, after being applied to the soil, if it is not completely decomposed, it will cause burnt seedlings, and because the livestock and poultry manure contains a large number of harmful bacteria such as E. increase in soil diseases

Embodiment 1-1

[0039] 1. Sampling: The hydrolyzed slag was taken from Henan Lianhua Monosodium Glutamate Co., Ltd.

[0040]2. pH adjustment: crush large pieces of hydrolyzed slag into powder or small particles, mix with powdered lime according to hydrolyzed slag: lime = 4:1, crush to 60 mesh with a chain crusher, and stack for 8 hours to allow it to fully react .

[0041] 3. Turn over: Use a forklift or manually turn over the pile, let the temperature of the reacted material cool down to normal temperature.

[0042] 4. Pulverization: The hydrolyzed slag cooled to normal temperature is measured, and the basic properties are shown in Table 3. The heavy metal content is far below the industry standard of bio-organic fertilizer (see Table 1), and is not measured.

Embodiment 1-2

[0050] Except following process, other is as embodiment 1-1.

[0051] The mixing ratio of hydrolyzed slag and powdered lime is hydrolyzed slag:lime=5:1. After mixing, crush to 70 mesh and stack for 10 hours. After cooling to normal temperature, the pH of the hydrolyzed slag is measured to be 5.5.

[0052] Bacillus subtilis (Bacillus subtilis), Bacillus megaterium (Bacillus megaterium) and Bacillus mucilaginosus (Bacillus mucilaginosus) are produced by separate fermentation, and the fermented bacterial liquid is prepared by using 100 mesh rice husk powder as bacterial liquid: rice husk powder=1 : 3 ratio adsorption, the three adsorbed single bacterial agents were mixed and pulverized to 70 mesh according to the ratio of 1:0.8:2.5, so that the total number of viable bacteria of the three strains after mixing reached 7.2×10 8 more than one per gram, and the water content is kept at 28%.

Embodiment 1-3

[0055] Except following process, other is as embodiment 1-1.

[0056] The mixing ratio of hydrolyzed slag and powdered lime is hydrolyzed slag:lime=4.5:1. After mixing, crush to 80 mesh and stack for 11 hours. After cooling to normal temperature, the pH of hydrolyzed slag is measured to be 7.1.

[0057] Bacillus subtilis (Bacillus subtilis), Bacillus megaterium (Bacillus megaterium) and gelatinous bacillus (Bacillus mucilaginosus) are fermented and produced separately, and the bacterial liquid after fermentation is pressed with 120 mesh rice husk powder according to bacterial liquid: rice husk powder=1 : 3 ratio adsorption, the three adsorbed single bacterial agents were mixed and pulverized to 80 mesh according to the ratio of 1: 1.2: 1.5, so that the total number of viable bacteria of the three strains after mixing reached 7.5×10 8 More than one per gram, the water content is kept at 29%

[0058] Ingredients: 217.5kg of powdery hydrolysis slag, 15kg of compound microbial ag...

Abstract

The invention provides a method for preparing multifunctional biological organic fertilizer and the technical scheme of the invention comprises fermenting bacillus subtilis, bacillus megaterium and bacillus mucilagimosus individually. The fermented bacterial liquid is adsorbed by rice husk separately. Three adsorbed single microbial inoculum is blended and grinded according to the proportion of 1:0.8-1.2:1.5-2.5 to obtain the compound microbial inoculum. The hydrolytic slag which is obtained in the production procedure of gourment powder after treatment is charged by trace element raw material and 4%-7% compound microbial inoculum with relative to total weight to obtain the needed compound microbe fertilizer. The method is simple in production technique, which facilitates to do batch production.

Description

technical field [0001] The invention relates to a production method of bio-organic fertilizer, in particular to a production method of producing multifunctional bio-organic fertilizer by using hydrolyzed slag produced in monosodium glutamate production. Background technique [0002] Soil is composed of minerals, organic matter and soil microorganisms. The transformation of mineral nutrients in minerals and organic nutrients in organic matter is mainly completed by microorganisms in the soil. Microorganisms are active factors in soil development. The life activities of microorganisms in the soil are based on soil organic matter, transforming soil nutrients, improving soil fertility, and providing effective ingredients for plant growth and development. Conversely, with the continuous maturation of the soil and the improvement of the fertilizer knife, the reproduction and growth of microorganisms are promoted, thus forming a benign ecological balance of the soil. However, du...
