Winter stacking farmyard should pay attention to what?

In winter, there are fewer agricultural activities and relatively abundant labor. This is a good time for stacking farmyard manure. Piles of decomposed farmyard fertilizers are available for spring use. However, in the winter, farmyard manure is piled up. Due to the low temperature, it is difficult for farmers to heat up after being piled on the heap and it is difficult to ferment and ripen. To solve this problem, pay attention to the following points in the specific operation: First, select the appropriate location. Should choose to be closer to the fat source, flat terrain, sunny leeward, convenient transportation as a stacking site. Second, increase the thermal fertilizer. In the stack of farmyard manure, the proportion of hot manure such as cow dung is increased, which is beneficial to the warming of fermentation. Third, add chemicals. If the stacking material is mainly manure, adding some of the superphosphate can not only accelerate the composting of the manure, prevent the loss of nitrogen in the manure, but also increase the content of organic phosphorus in the fertilizer and increase the efficiency of the phosphate fertilizer. If stacking materials are mainly crop straws and leaves, the addition of 0.5% to 1% of ammonium bicarbonate and appropriate amount of human waste will make it possible to adjust the ratio of carbon to nitrogen, promote the decomposition of straw, and at the same time improve the content of fertilizer. Nitrogen, improve fertilizer efficiency. If the proportion of human fecal urine in the stacking material is relatively large, the addition of 0.5% ferrous sulfate will allow the ammonium carbonate in human urine to be converted into stable ammonium sulfate, which acts as a nutrient and deodorizer to prevent the release of nitrogen. Fourth, control the humidity of compost. All kinds of stacking materials are mixed evenly, and at the same time, the humidity is adjusted so that they can be held in groups and scattered to the ground to prevent the humidity from being too high, and the air permeability after piled up is poor, and it is difficult to heat up and ferment. Fifth, increase the dung heap properly. The dunghill height requirement is more than 1.5 meters. The shape is preferably round. The outside of the dunghill is covered with dry straw, and then the mud cover film is closed to facilitate warming and heat preservation. Dung heap is too small, not easy to heat up, affecting the quality of compost. Six, the implementation of smoke warming. When the temperature is too low, a pit can be shaved in the dunghill and filled with inflammables such as hay. After the dunghill is built, it can be ignited. By slowly smoking, the temperature of the heap can be increased, and the compost can be rapidly warmed and fermented.
