How much is a new imported machine to return to the field? How much is the specific offer?

Straw returning to the field is an important measure to increase soil fertility in the world, which can not only put an end to the air pollution caused by straw burning, but also increase fertilizer and yield. However, if the method is improper, there may be all kinds of problems, first of all, it will hinder the emergence of main stubble wheat and strong seedlings; if the measures of soil moisture conservation in farmland can no longer keep up, it will also accelerate the loss of "green water" in topsoil, which is disadvantageous to the high yield of winter wheat. It can be said that the problem of uneven emergence and yellow seedling in the wheat field with straw returning is caused by the poor sowing quality of wheat caused by the non-standard operation of straw returning.

Therefore, in recent years, a new type of imported returning machine has been introduced in China, which has greatly improved the quality and efficiency of straw returning. Mechanized straw returning includes many forms, such as straw crushing, stubble crushing, whole rod burying, whole rod knitting and pressing, and so on. It has the advantages of convenience, speed, low cost and large area fertility improvement, and it is a more mature technology.

The main feature of mechanized straw returning to the field is the use of machinery to crush and bury the harvested crop straw or to bury the whole straw or to return the whole straw to the field. More than one working procedure can be completed at one time. Compared with manual operation, the work efficiency is increased by 40,120 times, which not only competes for agricultural time, but also reduces environmental pollution, enhances soil fertility, increases grain output, and has good social and economic benefits.

Its core technology is to use all kinds of straw returning machinery to return straw directly to the field, so as to decompose straw into organic fertilizer in the soil, so as to improve soil aggregate structure and physical and chemical properties such as water retention, water absorption, adhesion, air permeability, heat preservation and so on. increase soil fertility and organic matter content, so that a large number of abandoned straw directly turn waste into treasure.

The technical system includes wheat straw returning to the field: mechanical harvesting of wheat, mechanical crushing of straw, no-tillage sowing mechanical sowing corn or supplementary application of nitrogen and phosphorus fertilizer, deep ploughing and burying with high-column plough, sowing other crops after soil preparation or planting rice after soaking in water. The scope of popularization is suitable for wheat production areas in the north and wheat and rice production areas in the south.

After corn stalks were returned to the field to harvest corn ears manually, corn stalks were mechanically crushed, or mechanically combined harvested, and stalks were crushed at the same time, deeply ploughed and buried after N and P fertilizer application, and wheat was sown after soil preparation. This technique is suitable for the north and south corn producing areas. After the corn ears are harvested manually, the high column plough directly buries the whole corn straw, and it is suitable for the single season corn production areas in the northern dry farming areas.

After corn stubble is returned to the field and corn is harvested, corn straw is used for processing feed or living fuel. The corn stubble standing upright on the ridge was crushed by a stubble grinder and evenly mixed in a 10 cm plough layer. This technique is suitable for the application of rotational tillage in the northeast ridge farming area in the year without ploughing.

The rice straw is returned to the field to harvest rice, the straw is mechanically crushed and scattered in the field, and nitrogen fertilizer is applied after soaking the field, and then the whole machine for burying grass in paddy field such as reverse rotary tillage stubble machine or paddy field rotary tillage machine or paddy field driven rake is used to bury grass and prepare the ground. This technique is suitable for double-cropping rice or multi-cropping rice producing areas.

So how much can you buy this new type of imported machinery returning machine? How much is the specific offer? According to relevant agricultural data, medium-sized straw shredding machines start at 5500 yuan, small corn, rice straw and wheat straw machines start at 3650 yuan, and cotton straw machines generally start at 2500 yuan.
