Organic fertilizer production technology and leavening agent

this series of products are compounded with scientific formulas according to the difference of rich natural nutrients in different raw materials such as livestock manure, crop straw, domestic waste, sludge, sugar sludge, etc. After use, biological bacteria can rapidly colonize, decompose and release nutrients, activate insoluble mineral elements, improve crop nutrition, promote crop growth and enhance disease resistance. The long-term use of this product can greatly improve the soil fertility and water retention performance, improve soil fertility, optimize crop nutritional conditions, improve fertilizer utilization rate, and increase production and income

I. product ingredients: bacillus, photosynthetic bacteria, lactic acid bacteria, filamentous bacteria, yeast, fungi, bacteria, related enzymes and a small amount of functional bacteria such as nitrogen fixing bacteria, phosphate dissolving bacteria, potassium dissolving bacteria and antibiotic bacteria, which are compounded by different numbers of strains according to different raw materials, mainly aerobic fermentation

II. Function and function: it has a strong ability to decompose protein. At the same time, it can heat up, deodorize, eliminate diseases and pests, kill weed seeds in raw materials, and enrich nutrients. Nitrogen fixing bacteria can fix nitrogen independently in soil, have strong nitrogen fixing ability, and can secrete auxin to promote plant growth and fruit development. Phosphorus and potassium solubilizing bacteria can convert the invalid potassium and phosphorus in the soil that are not absorbed by crops into available potassium and available phosphorus that can be absorbed and utilized by crops. At the same time, they can release silicon, manganese, zinc, molybdenum and other elements in the soil and improve the nutritional level; Potassium and phosphorus dissolving bacteria produce gibberellin, cytokinin, indoleacetic acid and other bioactive substances in life activities, which can effectively stimulate the growth and development of crops. The antibiotics can rapidly colonize in the soil. The antibiotics produced by them can effectively inhibit more than 30 common soil borne diseases in the soil, have a unique role in disease prevention and seedling protection for crop growth, and can secrete a large number of plant growth regulating substances, which can increase production and income, improve crop quality, and effectively reduce the continuous cropping obstacles of crops when used on continuous crops. Perennial use can effectively improve soil structure and micro ecological environment

III. operation method

1 Preparatory work

(1) raw materials: this type of starter is mainly made of fresh chicken manure, sheep manure, pig manure and other materials with relatively high nutrition, and the water content is usually about 70%

(2) excipients: excipients with water content not greater than 10% (such as straw powder, rice bran, cake powder, peanut shell powder, etc.) must be crushed for better effect. They are mainly used to adjust the air permeability of raw materials during fermentation. If the air permeability of raw materials is good, they can not be added

(3) expansion of fermentation broth: use the weighed broth and auxiliary materials to mix evenly in the ratio of 1:10 (the purpose is only to expand the volume of the broth, so that some improvement measures can be taken to spread evenly on the original material), and then weigh and add the required broth and the treated raw materials at the rate of 10 tons per kilogram

(1) (2) raw materials and main materials can be used in reverse according to local actual conditions; Generally, the water content of livestock manure is large while that of straw is small. As long as the weight ratio is 3:1 or the c/n ratio is 25:1-30:1, there is no problem. See the following fermentation points for details

2. Production process

(1) if the moisture content of the raw material is more than 70%, it can be mixed with the auxiliary material in the weight ratio of 3:1, and then the expanded volume of bacterial agent can be added to the fermentation product (raw material), stirred and stacked evenly

(2) the water content of the mixed fermented product should be controlled at about 60% (hold it in a ball by hand, and it can be split when it is loosened. At least, it should be ensured that the water will not drop from the fingers when it is held hard by hand)

(3) stack the mixed fermentation products, with a height of about 1.2m, a width of about 2m and an unlimited length

(4) after 24-48 hours of fermentation, the temperature can exceed 55 ℃, and the deodorization effect can be achieved three days after heating

(5) it can be used as biological organic fertilizer after stacking and fermentation

3. Quality inspection:

it is (gray and black) brown, with slight ammonia smell and no odor. A large number of hyphae (powdery spores) may appear inside the stack

IV. key points of fermentation

a. precautions:

1. Poor permeability: in the strict fermentation process, the good or bad permeability directly affects the reproduction of anaerobic or aerobic bacteria. You can use the jack in the stack to bury the bound straw bundle in the stack, and use bamboo or wood sticks to hold up the bottom to increase its air permeability. Do not make it solid. In the stack stacking or fermentation tank type fermentation, pay attention to the proportion is the weight ratio, not the volume ratio

2. Water content: when fermenting with biological bacteria, the unspecified water content is about 60% (i.e. the hands form a mass and can be split when loosened). If the moisture content is too large, the temperature rise time will be delayed; otherwise, the temperature rise will be faster, but the temperature drop will be faster, and the decomposition will not be complete; Only proper moisture content can keep the fermentation material at a temperature of more than 50 ℃

3. Stir evenly: no matter whether the white plastic bags and yellow packing boxes are piled in the field to be put in the invisible forest, or the strip fermentation or tank fermentation, especially when the amount is large, it will be done manually, resulting in uneven temperatures. If the fermentation materials are not well mixed or the bacteria and fermentation materials are not well mixed, the deodorization effect is not ideal, which directly affects the quality of organic fertilizer

4. Use 100g of bacteria to ferment a ton of raw materials, and use about 1kg of straw powder to expand the volume unless otherwise specified

b. solutions to common temperature rise problems in the fermentation process:

1. Slow fermentation temperature rise is a problem of water regulation. First, check whether the water content is greater than 60%. If so, add equivalent auxiliary materials to adjust to 60% and mix well. If less than 40%, add water or fresh fecal water to adjust to 60% and mix well

2. C/n ratio is out of balance, and c/n is less than 12. Longitudinal retraction rate: gb/t 6671 ⑵ 001 determination of longitudinal retraction rate of thermoplastic pipes 20:1 will cause the temperature not to rise at degrees or the high temperature does not drop after the internal temperature rise of raw materials with c/n greater than 35. Generally, the c/n ratio is: 1; It can be adjusted by adding equivalent materials or inorganic elements

3. High or low pH may cause no temperature rise or keep the temperature below 50 ℃ for a long time, Adjust the pH value of fermentation products. Common products are salty. To reduce the pH value, add one of the following:

h3po4 (phosphoric acid) KH2PO4 (potassium dihydrogen phosphate) FeCl3 (ferric chloride) FeSO4 · 7H2O (black alum)

common products are acidic. To increase the pH value, add one of the following:

cao (quicklime) NaOH (caustic soda) K2HPO4 (potassium hydrogen phosphate)

addition method: spray after dissolving in water

4. Poor air permeability, straw powder can be added or supported at the bottom, and the pile can be turned over again; The temperature varies from high to low. If the mixing is uneven, it can be fully mixed

5. Pile body: 1.5m-2m wide and 0.8m-1.5m high. The weight should be about one ton. It can deodorize 3 days after the temperature rises

6. During production in open or mountainous areas, pay attention to wind protection, especially in winter and spring. When there is wind, cover the surrounding with film, but do not seal it tightly

c. the reason why the temperature will not rise within 5 days below 0 ℃ (see the above reasons for exclusion):

1. The stack body is small, the width should be more than 1.8m, and the height should be more than 1.5m. Otherwise, the external temperature is too low, and the surface layer is frozen, causing anaerobic and unable to rise

2. If the water content is large, the water content should be about 50%. If the water content is too small, the fermentation effect will be poor. If the water content is too large, the temperature will not rise or the temperature will start to drop after the temperature rises to degrees, or even will drop below zero

3. The mixing is uneven. When the mixing volume is large, it will be done manually, which will cause uneven temperature

normal phenomenon during fermentation: maggots and small flying insects are produced on the surface layer, white hyphae are produced below the surface layer, the color is brown, ammonia smell is released, and the stack volume may be reduced by about one third

when the temperature reaches 55 ℃, the stack is turned every other day on average, so that the upper, middle and lower parts of raw materials are fully decomposed and decomposed. Ordinary materials can be used as base fertilizer every day. The fermentation days of straw with more fiber should be controlled within days. It is more scientific to determine the fermentation cycle according to the different properties of raw materials and the crushing fineness of raw materials
