How to build quality farmyard fertilizer in winter

Less farm work in winter is a good time to build farmyard fertilizers. However, because of the low temperature, the man-made farmyard fertilizers are not easy to ferment. Therefore, it is necessary to grasp the following four links when composting:

First, the site selection should be closer to the fat source, leeward and convenient transportation.

Second, the heap of manure dumps is preferably round in shape and has a height of more than 1 meter to facilitate thermal insulation. After determining the bottom of the manure pile, first coat a layer of culvert or grass, and stack the mixed manure evenly. When composting, it is necessary to pay attention to increase the proportion of hot manure and other fertilizers and reduce the amount of water and soil. This will not only result in fast fermentation but also good quality.

Third, antifreeze winter dunghills are easily frozen and affect the quality, and increase the dunghills, slow heat distribution, is conducive to fermentation. In addition, in order to speed up the freezing of the manure fermentation, a pit (a large pile of poop can be planed for two) can be shaved in the dunghill, the weeds can be piled in the pit, and then the raw smoke can be ignited and smoked slowly, but care should be taken not to burn the grass. .

Fourth, seal around the dung heap first with grass cover, so that it forms a 30 to 50 cm thick insulation layer, and then mud closed, conditional can also cover the waste plastic film insulation.
