Straw manure composition and manure operation method

Abstract

The invention relates to a straw manure composition and a manure operation method. The straw manure composition comprises the following components: 100 to 120 kg of crop straw, 0.5 to 0.7 kg of urea, 2 to 3 kg of 12 percent of calcium superphosphate, 100 to 200 kg of fresh soil, and a proper amount of water. The manure operation method comprises the following steps of: A, digging a pit with the depth of 0.5 to 0.8 meter on the edge of the field; B, uniformly and fully mixing the crop straw with other materials except the water, stacking the materials in the pit to form a stack of 2 to 2.5 meters higher than the ground, covering the outer surface of the stack by using soil, and forming a concave pit in the middle of the top of the stack; C, filling the concave pit with water to ensure that the concave pit conveniently receives natural rainfall in future; D, when the stack collapses and the volume shrinks after a period of time, covering the exposed straw on the stack by using a proper amount of soil so as to accelerate the thorough decomposition; and E, after the crop straw is thoroughly decomposed for 3 to 6 months, obtaining the straw manure. By using soil water absorbability and rich microbes, the problem that the wheat straw containing a non-absorbent waxy layer does not absorb water and the problem of manure strain are solved, and the wheat straw is changed to a high-quality organic fertilizer resource from waste.

Description

technical field [0001] The invention belongs to a method for making waste into organic fertilizer, in particular to a method for composting straw returning to the field. Background technique [0002] Compared with developed countries, there is still a huge gap in the organic matter content of my country's cultivated land. The average organic matter content is more than 30% lower than the world average and more than 50% lower than that of Europe. Increasing the organic matter content of cultivated land soil has always been a difficult point in my country's agriculture. One of the important reasons is that the abundant and renewable straw resources have not been well utilized. Mature, unstable effect on crop yield. There are many and in-depth studies on the positive effects of straw returning on improving soil, improving soil fertility, protecting the ecological environment balance of farmland, and preventing air pollution. However, how to return to the field will achieve bet...
