Embodiment 1

[0029] This embodiment is a method of returning corn stalks to the field under the ridge platform. The process of this method is as follows: figure 1 shown, including the following specific steps:

[0030] Step 1: Straw crushing. After the corn is harvested, it is taken away from the farmland together with the straw. Use a straw grinder and other tools to crush the straw, and the length of the crushed straw should be less than 15cm.

[0031] Step 2: Deep Loosening Ditch. Perform deep loosening and ditching operations at equal intervals in the farmland, and place the excavated soil on both sides of the ditch, such as figure 2 As shown, 1 is the deep loosening ditch, the ditch depth is 25-35cm, the ditch width is 30-45cm, and the distance between adjacent ditches is 60-75cm; tools such as deep loosening shovels can be used for operation.

[0032] Step 3: Fill the straw into the deep loose ditch. Fill the crushed corn stalks into the deep loose ditch.

[0033] Step 4: Appl...

Embodiment 2

[0046] This embodiment is a method for returning corn stalks to the field under the ridge platform, including the following steps:

[0047] (1) After the corn is mature, it is harvested by a combine harvester. When harvesting, the corn stalks can be chopped into small pieces of <13cm by the harvester, and distributed in strips on the soil surface.

[0048] (2) After the corn is harvested, the corn stubble cutter is used to remove the stubble of the corn.

[0049](3) Sprinkle 30kg / ha of microbial agent to promote straw decomposition and 100kg / ha of urea (combined with pure nitrogen 46kg / ha) to corn stalks.

[0050] (4) Use a subsoiling shovel to deeply loosen the furrows on the farmland. The depth of the ditch is 35-40 cm, the width of the ditch is 30-40 cm, and the distance between adjacent ditches is 60-75 cm. While ditching, put the straw mixed with microbial agent and nitrogen fertilizer into the deep loosening ditch, then backfill the ditch with soil, and mix well with it...

Abstract

The invention relates to a method for returning corn straw under ridges. The method includes the steps that firstly, the corn straw is smashed; secondly, deep scarification and ditching are conducted in farmland to form deep scarification ditches; thirdly, the deep scarification ditches are filled with the smashed corn straw; fourthly, soil is gathered in the deep scarification ditches, and ridges are formed on the deep scarification ditches filled with the corn straw. Further, when the deep scarification ditches are filled with the smashed corn straw, a straw decomposition agent can be used, a proper quantity of nitrogen fertilizer is applied, and the straw decomposition agent, the nitrogen fertilizer, the straw and soil are evenly mixed. A thick soil layer without the straw covers the ridges after ridging, and the crop emergence rate is ensured; small wavy slopes can be formed on the surface of the farmland, the surface area of the soil is increased, and the solar radiation temperature increase function is remarkable; the heat preservation and moisture conservation effects of soil under the ridges are remarkable. The method can promote quick decomposition of the corn straw, the period for converting the corn straw into soil organic matter is shortened, the fertility level of the farmland can be quickly improved, and the crop yield is ensured.

Description

technical field [0001] The invention relates to the field of farmland cultivation and crop cultivation, in particular to a method for returning corn stalks to the field under a ridge. Background technique [0002] In the process of corn planting and production, a large amount of straw will be produced. The traditional way of straw disposal is to feed livestock or burning, incineration, the latter will bring serious environmental pollution. Due to the rapid development of my country's economy in recent years, the changes in planting and breeding structures, and the improvement of agricultural mechanization, great changes have taken place in straw treatment methods, and the general trend is to change to the direction of environmentally friendly comprehensive utilization of straw. As one of the main utilization methods, straw returning to the field can not only improve the physical and chemical properties of the soil, increase the content of soil organic matter, but also save ...
