Main materials: corn straw, bran, superphosphate, lime, urea, fine soil, etc.
Method: 3% bran, 1% calcium superphosphate, 2% lime, 0.2% urea and mix well. Choose fresh and mold-free corn straw and dry it. Depending on the water content of the corn straw, add water. The ratio is 1: (1 - 1.8). Take a piece of plastic film, depending on the height of the corn straw, the length depends on the amount of material. Spread the plastic sheet on the ground, place the corn straw on the end of the plastic sheet, the thickness is 20 cm, then spread the auxiliary material evenly on the corn straw, flip it slightly with your hand, and mix the auxiliary material with the corn straw. Then put a layer of corn straw and then spread the auxiliary. By analogy, after pushing 5-7 layers of corn straw, fold the plastic sheet and surround the fermentation. When the temperature reaches 65 °C, start to turn the corn straw, turn it over to the bottom, and turn it underneath. Above, then cover it again, and the pile is completed when the temperature reaches 65 °C.
