Use a rotary tiller to spin the land year after year so that crops can grow well.

Rotary tiller is also a new operation mode with the popularization of agricultural production mechanization in our country in recent years. It is certain whether rotary tiller operation is helpful to agricultural production, but rotary tiller operation also brings a lot of problems. The working depth of the rotary tiller is insufficient, and the ability to break the bottom of the plow is insufficient. But this is not absolute, rotary tiller can also do deep ploughing, but the depth is still a little shallow, and this will also give rise to a series of problems, the following for you to introduce.

Trigger soil consolidation

This is a hidden danger caused by the typical rotary tiller operation. Usually the ploughing depth can reach 30 cm or more, while the working depth of the rotary tiller is basically 20 cm. Of course, this is not to say that the rotary tiller can not work deeper, but it is also possible. At present, agriculture is basically a small-scale peasant economy, directly looking for machine owners with rotary tillers at the time of cultivated land, this kind of cultivated land will not be further adjusted for the sake of cost. Causing the plough layer to become shallower directly. Therefore, the gradual shallowness of the plough layer also leads to the deterioration and hardening of the surface fertile soil.

It is not conducive to further release of farm manure.

The application of farm manure in agricultural production is a common measure, but if the plough layer is too shallow, it will affect the further maturity of farm manure, especially the straw returning technology implemented in agricultural production, because the straw can not be deeply rotten, fertility is difficult to play.

Cause soil-borne diseases and insect pests

One of the reasons for advocating deep ploughing in production is that we hope to reduce the harm to crop roots, germs and bacteria through deep ploughing, but the rotary tiller is not deep enough to eliminate these hidden dangers.

At present, many areas promote the technology of deep loosening tillage of agricultural machinery, and provide subsidies of 20-50 yuan per mu for agriculture with deep loosening machinery and operations, hoping to increase farmers' use of subsoiling tillage to improve soil by means of subsidies. to achieve sustainable agricultural production of cultivated land in China.

Here is science to promote agriculture, welcome to follow, take you to grow knowledge.
