First, add the incompetent microbial agent. Muscular inoculants are microbial living preparations that can accelerate decomposition and decomposition of various organic materials (including crop stalks, animal manure, domestic waste, and municipal sludge, etc.). Muscular inoculants have a high content of viable bacteria, a low dosage, and adapt to a variety of different compost substrates; they have a rapid temperature rise and a short compost cycle.
Second, add the fungus. Bacterial fertilizer not only provides organic nutrients, inhibits and kills harmful microorganisms in the rhizosphere, but also increases the granule structure of the soil, relieves the nutrient elements that are solidified in the soil, has strong adsorption and decomposition and transformation and utilization capacity, and enhances the water retention and protection of the soil. Fertility. The microorganisms in the bacterial fertilizer are mainly aerobic bacteria. The microbiological process of aerobic composting can be broadly divided into three phases (heat production phase, high temperature phase, and maturity phase), and each phase has its own unique microbial group.
Fertilizer use method and dosage:
1. Usage: Add 1 to 3 bags per cubic meter of farmyard fertilizer. The best fermentation period is spring, summer and autumn. The temperature in winter is too low. The bacteria in the fungicide are mostly in dormant state, and the fungus exerts poor function and long fermentation time.
2. Dosage: According to the difference of environment temperature and fermentation materials, the amount of bacteria added: 1 to 3 bags/cubic meter (40 kilograms per bag), 2 to 3 bags/cubic meter for early spring, late autumn and winter, late spring, In summer and early autumn, add 1 to 2 bags/cubic meter of fungus.
3. Mixing: Evenly spread the bacterial fertilizer into the material, and control the moisture content of the material at 50% to 70%, that is, grasping the material out of the water but not flowing water. Mixing and then stacking and waiting for fermentation. At the beginning of composting, this stage is the heat production stage, which takes about 5 to 15 days, and the temperature is in the range of room temperature and 50 degrees.
4. Turning over: Measure the temperature inside the reactor. When the temperature rises above 50°C from the stage of heat production, it will enter the high temperature stage. In the 60 °C ~ 80 °C high temperature stage, keep it for more than 3 hours, turning rake, and add a small amount of water to make up for the loss of moisture during the tumbling and accumulation process, turn around 1 or 3 times a week. Twisting requirements fully uniform, to achieve the role of ventilation and cooling. This phase lasts about 10 to 30 days.
5. Decomposition: When the temperature of the stockpiles drops below 50°C, the mesophilic microorganisms will once again predominate, and the organic substances that are more difficult to decompose will be further decomposed, and the humus will increase and tend to stabilize. At this time, the compost will enter the decomposed stage until When the temperature drops below 40°C, the fermentation is over. This stage takes about 7 to 14 days. As the temperature drops, the oxygen demand decreases and the fat heap space increases. At this time, only natural ventilation is needed, and the humidity is kept as low as 10% to 15%. The fermented farmyard manure is piled on a place with less light and covered with a film, which can slow down the farmer's fat.
