The Mechanism And Effect of Bio-Organic Fertilizer-Organic Fertilizer Production Line
Bio-organic fertilizer is very effective
Bio-organic fertilizer is organic solid waste (including organic waste, straw, livestock and poultry manure, cake, agricultural and sideline products, and solid waste from food processing) that is processed by biological fertilizer strains after fermentation, deodorization and complete decomposing. . It can regulate the soil, activate the activity rate of microorganisms in the soil, overcome soil compaction, and increase soil air permeability. Bio-organic fertilizer can also improve the fertility of the soil and greatly increase the production of food crops, cash crops, vegetables, and fruits.
The process of making bio-organic fertilizer
The production of bio-organic fertilizer for animal manure can be divided into two methods: static processing and dynamic processing. Generally, the method used by households to make organic fertilizer is static processing, which is simple in method, easy to operate, low investment, and suitable for small-scale farming specialized households to operate.
- Preparation of raw materials and auxiliary materials
Choose a piece of land with a flat ground and no water accumulation, and stack the livestock and poultry manure and auxiliary materials separately. Generally, granular or powdered wheat bran, peanut shell powder, etc. are used as main auxiliary materials. If you use corn stalks, cotton stalks, etc. as auxiliary materials, you must first cut them into lengths of 5-10 cm. Too long will make mixing inconvenient. The purpose of adding auxiliary materials is to adjust the water content and carbon-nitrogen ratio of chicken manure and increase the air permeability of the fermented product.
- Operation steps
Sprinkle the bacteria evenly on the prepared chicken manure and stir evenly. During the mixing process, the moisture content of livestock and poultry manure should be adjusted to about 60%. If the water content is too high, it is necessary to sprinkle auxiliary materials such as wheat bran and corn stalks on the livestock and poultry manure to reduce the water content of the raw materials. If the water content is too low, you should add fresh raw materials or sprinkle some water. Stack the mixed materials on the fermentation platform in a stack, at this time, the height is about 1-1.2 meters.
- Management of fermentation process
During the fermentation process, the control of temperature is very important. The temperature is too low to reach the maturity standard. When the temperature is too high, the nutrients in the compost are easily lost. Turn the pile properly when the temperature reaches about 60 degrees.
Requirements for fermentation temperature and time:
After composting, the raw materials enter the first fermentation stage. It will automatically heat up to above 55°C and maintain it for 5 to 7 days. At this time, most of the parasite eggs and harmful bacteria can be eliminated, reaching the harmless treatment standard. Turn the pile once in about 2 to 3 days, which is conducive to ventilation, heat dissipation, and even decomposing. After 7-10 days of fermentation, the temperature in the compost drops below 40°C, and the color of the bio-organic fertilizer changes to dark brown or yellow-brown. The organic fertilizer inside the compost has a large amount of white mycelium attached to the surface, which is odorless and has a slight ammonia smell, which has reached the maturity standard, and can be directly used as a base fertilizer or top dressing in the field.
- Matters needing attention in the fermentation process
In the process of manufacturing bio-organic fertilizer by static method, attention should be paid to:
Covering the surface of the fermented material with a layer of about 10 cm of finely chopped straw or sprinkling a layer of calcium persulfate can reduce the evaporation of ammonia and avoid the loss of nutrients. In case of strong wind during the fermentation process, the top should be covered with breathable materials such as straw to reduce the evaporation of water and the loss of temperature. Livestock manure is stored for too long or there are more straws and weeds in the manure, and there is less manure. You can add some rapeseed meal, urea or fresh livestock manure to increase the nitrogen content, increase the carbon-nitrogen ratio, and speed up the fermentation speed. , Improve the quality of fertilizer. The pH value of the compost should be controlled at 5.5-8.5. If the pH value of the compost is lower than 5.5, it is too acidic and can be adjusted by adding quicklime appropriately. It is necessary to avoid making bio-organic fertilizer in the open air during the rainy season to prevent the moisture from being too high. If there is high moisture content and poor air permeability during the, a few straws can be inserted in the middle of the fermentation pile to help air permeability.
