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:
Choose the suitable place should choose to be closer to the fat source, and the terrain is flat, leeward, convenient transportation as a place for stacking.
Increasing the amount of thermal fertilizer in the stack of farmyard manure increases the proportion of hot manure such as horse dung and sheep manure, which is beneficial to warming fermentation.
Adding chemical substances 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.
Control the moisture content of the compost and mix the various stacking materials. At the same time, adjust the humidity so that it can be held in groups and scattered to the ground to prevent the humidity from being too high. After the stack, the air permeability is poor and the temperature rise and fermentation are difficult.
Appropriately increase the height of the manure pile stack is 1.5 meters or more. The shape is preferably round. The outside of the waste pile is then covered with dry straw, and 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.
When the temperature of the smoke warming is too low, a pit may be shaved in the dunghill and filled with inflammables such as hay. After the dunghill is built, it will be ignited, and the temperature of the heap will be increased by slow smoking to promote rapid temperature rise and fermentation of the compost. .
