Second, add water to promote maturity. Dry in winter, large amount of evaporation, if the water is insufficient, the microbial activity is inhibited, and the straw inside the compost is not easy to rot. In the process of stacking, water manure or sewage is often added to make the material in the pile swell and promote microbial activity. Fermented and decomposed. It is more appropriate to use the bottom of the pile to produce moisture when composting and adding water.
Third, turn piles to promote uniformity. Winter composting needs to be turned 2-3 times during the stacking period, and each time of turning over the pile should be mastered within a few days after the high temperature in the pile. And add manure, sewage, human and animal waste. When turning over, turn the piles on the top and the surrounding into the pile, and turn the piles in the original pile out of the surrounding and cover the upper layer, so that all the compost materials are evenly rotted.
Fourth, the application method. The completely composted compost is generally brown. All the materials have been rotted and stinky. They are rich in organic matter, high in fertility and long in fertilizer. In the coming spring, they can be used as base fertilizer. The application method can be applied as a strip or acupoint, and the dosage is 2000-2500 kg. It can also be spread evenly on the ground before tilling, then turned into the soil, and then evenly spread through the hoe or the field to make fertilizer and soil. Integration, reducing the loss of fertilizer, improving soil fertility, and laying a good foundation for the harvest of crops.
