Embodiment 1

[0037] Select the corner of the field, dig a "Tiantou cellar" with a depth of about 0.8 meters, a width of about 1.5 meters, and a length of about 2 meters, and pile part of the soil dug out of the cellar around the cellar, and step on it as a cellar ridge. , and the other part is piled aside, and the straw is piled up to cover the straw. Stack the wheat straws in layers and step on them. The first layer is 40-50 cm (thickness after being stepped on), the second layer is 30-40 cm, the third layer is 20-30 cm, and the fourth layer is 20 cm. After each layer is stepped on, 1 kg of straw decomposing agent and 2 kg of urea are used to spread evenly. After the straw is piled up, cover it with soil evenly on the top of the pile. The soil is covered with a thickness of 5 cm, and the field water and rainwater are used to infiltrate. If it deepens, the straw will turn black and brittle after one month, and the straw will be easily broken. After three months, the straw will gradually r...

Embodiment 2

[0040]Select the corner of the field, dig a "Tiantou cellar" with a depth of about 0.8 meters, a width of about 1.5 meters, and a length of about 2 meters. The soil dug out of the cellar is placed around the cellar, and it is used as a cellar ridge. Stack the rape straws in layers and step on them firmly. The first layer is 40-50 cm (thickness after stepping), the second layer is 30-40 cm, the third layer is 20-30 cm, and the fourth layer is about 20 cm. After each layer is stepped on, about 1 kg of straw decomposing agent and about 2 kg of urea are evenly spread on each mu. After the straw is piled up, cover the top of the pile with rapeseed husks to a thickness of 5 cm. After using the field water and rainwater to infiltrate the straw pile to rot, about 10 days after encountering water, the pile body sinks, the straw becomes soft, and the color deepens. After one month, the straw becomes black and brittle, and the straw is easy to break. Stinking; the straw below is whitish...

Abstract

The invention provides a method for composting and returning crop straws to a field. The method comprises the following steps: digging a pit in suitable size at a corner of the field; stacking the straws in the pit in a layering way and treading down the straws; spreading a right amount of straw ageing agents and urea in each layer; after finishing stacking the straws, uniformly covering the top of the stack with the soil dug from the pit; after composting for several months, digging out the rotten straws from the pit and returning the straws to the field after harvesting crops in next season; and uniformly spreading the rotten straws in the field and using the rotten straws as base fertilizers, wherein organic matters got after the straws are rotten become clean green fertilizers. Under the condition of using the fertilizers, the hardened land becomes soft and loose, the fertilizer cost of peasants for farming is saved, and the environmental pollution problem caused by burning the straws is relieved.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of crop straws, in particular to a method for returning crop straws by composting. Background technique [0002] my country is a big agricultural country, with large crop output and a large amount of crop straw. In addition to being used for animal feed, field fertilizer, industrial raw materials, etc., there are more than 300 million tons of surplus every year. With the development of agriculture, the output of crops increases, and the output of straw continues to increase. However, in some relatively developed areas of our country, with the development of rural economy and the increase of farmers' income, the energy consumption structure of farmers' residents is undergoing obvious changes. Commodity energy sources such as coal, oil, gas, and electricity have become more and more widely used; crop straw, which has long been the main fuel, has become waste, or occupies certain farmland fo...
