In winter, the temperature is low and the farmyard manure produced is not easy to ferment. However, if the following issues are noticed, the compost will be decomposed faster and the quality will be improved: The location of the manure accumulation at the compost site should be closer to the manure source, leeward and convenient to transport. The manure heap area of ​​the manure heap is preferably round in shape. The height of the manure pile is generally more than 1.5 meters, otherwise it is not easy to keep warm. Combine and mix the various farmhouse manures. Increasing the proportion of hot fertilisers Winter plots of farmyard fertilisers should be appropriately increased with large livestock manure and other hot fertilizers. This will not only speed up the fermentation of the fertilizer, but also provide good quality. In addition, the amount of water and soil should be appropriately reduced to increase the temperature of the dung heap and speed up the fermentation. After the composting method determines the bottom of the excrement pile, we must first spread a layer of weeds, and stack the mixed farmhouse fertilizers one by one until they reach the required height. Increase the temperature of dunghills in winter. If the dunghills are too small, they are easily frozen and cannot be fermented, affecting quality. After increasing the dunghill, the heat is distributed slowly, which is conducive to fermentation. Sealing mud insulation In order to maintain the temperature of the dunghill and prevent nutrient loss, it can be covered with corn leaves or weeds around the dunghill to form a 30-50cm insulation layer. The old sorghum stalks are then coded on the outside and then the mud is closed. . After adding the insulation layer, the organic matter content of the manure heap can be increased by 1.96%, and the available nitrogen and available phosphorus are also greatly improved.
