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. Select a good place for composting, first select the source closer to the manure, leeward sunny and convenient transportation. Plan the landfill area of ​​manure piles. The shape of the manure pile is preferably circular. The height of the manure pile is generally more than 1.5 meters, otherwise it is difficult to keep warm. Combine and mix the various farmhouse manures. To increase the proportion of hot fertilisers, winter plots of farmyard manure 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 also be 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, a layer of yellow excrement or various grasses is spread first, and the various farmhouse fertilizers are then piled up and stacked one by one until the required height is reached. Pay attention to the fact that the excrement piles are cold in winter. If the excrement piles are too small, they can easily be frozen and cannot be fermented, affecting the quality. After increasing the dunghill, the heat is distributed slowly, which is conducive to fermentation. It is best to use sealed mud insulation in order to maintain the temperature of the dunghill and prevent loss of nutrients. It can be covered with corn leaves or wild grass around the dunghill to form a 30-50cm insulation layer, and then the old sorghum stalks are coded on the periphery. Then Clay closed. Compared with no insulation layer, the content of organic matter increased by 1.96%, and the available nitrogen and available phosphorus also greatly improved. Speed ​​up frozen manure fermentation Plane a pit in a dunghill (two large poops can be planed), piling up grass in the pit, and then ignite fumes and slowly smoke nausea. However, it should be noted that the ignition fumes are not fire burning, so as to avoid overheating and failure of manure. In addition, in order to prevent the cold wave from invading, a layer of thin soil or grass shall be placed on the dunghill. Conditional should also cover old plastic sheets. After the dung has been defrosted, it has been dug for more than 10 days. China Agricultural Network Editor
