Embodiment 1

[0055] The present embodiment relates to a kind of preparation method of multifunctional Bacillus subtilis bacterial agent, it comprises the following steps:

[0056] 1), prepare bacterial classification, be about to add 10 Kirschner flask seeds and aseptic water to make bacterial suspension, inoculate in the large tank under aseptic condition;

[0057] 2) Fermentation medium, namely yeast powder with a content of 2.2w / v% and a fineness ≥ 80 meshes, industrial-grade cornstarch with a content of 1.5w / v%, industrial-grade calcium carbonate with a content of 0.5w / v%, The volume of industrial grade potassium dihydrogen phosphate with a content of 0.24w / v%, industrial grade ammonium sulfate with a content of 0.6w / v%, and industrial grade defoamer with a content of 0.055w / v% after sterilization is the fermenter In a tank with 65% volume, the pH before sterilization is 7.15~7.7; then keep the ventilation volume at 1:0.5 during the period of 0~8h, and keep the ventilation volume at 1:...

Embodiment 2

[0071] 1. Raw material pretreatment:

[0072] Dried the Ningnan bacteria residue, crushed it, and sieved it with a 40-mesh sieve; the peat soil was broken and sieved through a sieve hole of 0.4-4cm by a turning machine;

[0073] 2. Mixing:

[0074] (1) Use a forklift to put 8t of coal gangue, 6t of pig manure, 55t of peat soil, 20t of rice husk powder, 12t of fungus residue, 80kg of multifunctional Bacillus subtilis, and 2t of zeolite powder into the above raw materials in sequence from the bottom to the top. Spread evenly in the middle of the fermentation tank, use a manual throwing machine to turn the above mixed materials back and forth until all the materials are mixed evenly;

[0075] (2) Mix the materials and make them level. The height of the entire fermented materials is not higher than 80 cm. At this time, use an automatic throwing machine to overturn, add water to the materials while overturning, and calculate the added moisture according to the rate of 3t / h. It is...

Embodiment 3

[0078] The bean cake is dried, crushed, and sieved through a 40-mesh sieve; the peat soil is broken and sieved through a 0.4-4cm sieve hole by a turning machine;

[0079] 2. Mixing:

[0080] (1) Use a forklift to mix 18t of coal gangue, 8t of chicken manure, 120t of peat soil, 28t of corn stalks, 18t of bean cake, 130kg of multifunctional Bacillus subtilis, and 4t of zeolite powder in order from the bottom to the top. Lay it in the middle of the fermentation tank, use a manual turning machine to turn the above mixed materials back and forth until all the materials are mixed evenly;

[0081] (2) Mix the materials and make them level. The height of the entire fermented materials is not higher than 80 cm. At this time, use an automatic throwing machine to overturn, add water to the materials while overturning, and calculate the added moisture according to the rate of 3t / h. It is advisable to control the time at 10-12h, so that the relative moisture of the whole fermentation mate...

Abstract

The invention relates to a biological organic fertilizer and a preparation method thereof. The biological organic fertilizer is mainly prepared from, by weight, 8-35 parts of gangue, 10-20 parts of animal dung, 55-180 parts of turfy soil, 20-50 parts of rice hull powder and / or straw, 8-35 parts of cake fertilizer, 1-5 parts of zeolite powder and 0.25-0.7 part of bacillus subtilis fungicide. The bacillus subtilis fungicide is solid fungicide, and in the solid fungicide, the number of viable organisms and / or viable spores is larger than or equal to 10,000,000,000 per g. The fertilizer can provide whole nutrition for crops and improve the fertilizer efficiency, and has good ecological benefits, energy can be reasonably recycled, the rural ecological environment is protected, and a good agricultural ecological system is created. In addition, due to the adoption of the bacillus subtilis strain screened by the applicant, the biological organic fertilizer further has the effect of preventingand controlling multiple fungal and bacterial diseases.

Description

technical field [0001] The invention relates to the field of microbial fertilizers, in particular to a biological organic fertilizer and a preparation method thereof. Background technique [0002] At present, in order to increase the yield of crops, people use various chemical fertilizers or seedling strengthening agents. Seedling strengthening agents are a new type of disinfectant, chemical control agent, and nutrient that are developed according to the physiological and ecological characteristics of rice seedlings and the physical and chemical properties of soil. Seedling bed soil conditioner. [0003] Inorganic fertilizers have high nutrient content, fast fertilizer efficiency, small size, light weight, and are easy to apply. At the same time, the effect of increasing production is obvious, and they are highly praised by farmers. However, with the large-scale application of chemical seedling-strengthening agents, the soil pollution has increased year by year, which chang...
