Description

A kind of machine for ridge-growing corn stalks under the ridge

technical field

The utility model belongs to the technical field of agricultural tillage machinery, in particular to an agricultural machinery for returning corn stalks to the field under the ridge platform.

Background technique

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 resources and energy, and reduce environmental pollution. It has received more and more attention worldwide.

After the corn is harvested, the traditional method of returning the straw to the field is to crush the straw first, and then mix or turn the straw into the plow layer soil with agricultural machinery such as a rotary tiller or a plow. With traditional farming methods, the thickness of the soil plow layer in most farmlands in my country is only 10-15cm. As a large biomass crop, corn produces a large amount of stalks per season; crushing corn stalks and returning them to the plow layer soil will greatly reduce the surface soil bulk density, increase soil air permeability, and keep water and fertilizer in the plow layer soil. Severe decline in sex, resulting in lower crop emergence and reduced yield. The most important thing is: the traditional straw returning requires multiple machines to complete the corresponding steps respectively, which is difficult to operate and causes serious waste of resources, so it is difficult to be widely used or promoted.

In practice, to solve the above problems, design a machine that can bury the straw in the deep soil, and add solid nitrogen fertilizer decomposing agent and other substances to help the straw decompose. The surface soil is ridged, and normal farming can still be carried out. One-time Returning to the field of agricultural machinery is particularly important.

The beneficial effects of the utility model are:

Compared with the existing technology, the above-mentioned ridge-growing corn stalk returning machine under the ridge can dig a deep pit at one time, inject a large amount of straw into it, and simultaneously apply solid nitrogen fertilizer and liquid decomposing agent to promote the rapid decomposition of corn stalks. It decomposes and releases nutrients for crops to absorb and utilize, shortens the cycle of its transformation into soil organic matter, and rapidly improves farmland fertility. The surrounding surface soil is also loosened, and at the same time, the surface soil is covered on the straw surface to form a ridge. After the farmland is ridged, a wavy small "slope" will be formed to increase the soil surface area. The solar radiation will increase the temperature of the returning straw and the soil, and the heat preservation effect will be obvious without affecting the follow-up operations. It saves a lot of manpower and material resources, so that farmers can more conveniently complete the arduous work of returning straw to the field at one time. And does not affect the subsequent cultivation.
