1. Add rotten fungicide. The decomposing fungicide refers to a microbial living preparation that can accelerate the decomposition of various organic materials (including crop straws, livestock and poultry manure, domestic waste, and urban sludge, etc.). The fungicide has a high content of live bacteria, a low dosage, and is suitable for a variety of different compost substrates; it has a fast rise temperature and a short compost cycle.
2. Add bacterial fertilizer. Bacterial fertilizer can not only provide organic nutrients, inhibit and kill harmful microorganisms in the rhizosphere, but also increase the soil's aggregate structure, remove the nutrient elements solidified by the soil, have strong adsorption, decomposition, transformation and utilization capabilities, and enhance soil water retention Fat capacity. The microorganisms in the fertilizer are mainly aerobic bacteria. The microbiological process of aerobic composting can be roughly divided into 3 stages (thermogenesis stage, high temperature stage, and maturation stage), and each stage has its own unique microbial group.
Method and dosage of bacterial fertilizer:
1. Method of use: Add 1 to 3 bags of fertilizer per cubic farm. The best fermentation period is spring, summer, and autumn. The temperature is too low in winter. Most of the bacteria in the bacterial fertilizer are in a dormant state. The bacterial fertilizer does not work well and the fermentation time is long.
2. Dosage: According to the difference in ambient temperature and fermentation materials, the amount of bacterial fertilizer added: 1-3 bags / cubic meter (40 kg per bag), 2-3 bags / cubic meter of bacterial fertilizer in early spring, late autumn, and winter, late spring, In summer and early autumn, add 1-2 bags of bacterial fertilizer / m3.
3. Mixing: Sprinkle the bacterial fertilizer evenly into the material, and control the moisture content of the material to 50% to 70%, that is, hold the material out of the water tightly by hand, and then store it until fermentation. In the early stage of composting, this stage is a heat-generating stage, which takes about 5 to 15 days, and the temperature is in the range of room temperature and 50 degrees.
4. Tumble: Measure the temperature inside the reactor. When the temperature rises from the heat generation stage to more than 50 ℃, it will enter the high temperature stage. In the high temperature stage of 60 ℃ ~ 80 ℃, keep it for more than 3 hours, carry out tamping, and add a small amount of water to make up for the loss of water during the tamping and accumulation process, tamping 1 to 3 times a week. The tumbling needs to be sufficiently uniform to achieve the effect of ventilation and cooling. This phase lasts about 10-30 days.
5. Maturation: When the temperature of the stockpile falls below 50 ° C, mesophilic microorganisms will dominate again, and the remaining difficult to decompose organic matter will be further decomposed, and the humus will continue to increase and tend to stabilize. When the temperature drops below 40 ° C, the fermentation is completed. This stage takes about 7 to 14 days. Due to the decrease in temperature, the oxygen demand is reduced, and the gap between the fertilizer piles is increased. At this time, only natural ventilation is required, and the humidity is kept as low as 10% to 15%. The fermented farmhouse manure is piled up in a place with little light, and covered with a film, which can slow down the farmhouse manure.
