Straw comprehensive utilization mechanization technology

At present, there are more than 10 advanced mechanization technologies for solving crop straw in China, which mainly include straw returning, silage, ammoniation, briquetting, bundling, plate making, gasification and so on.

1 Straw returning mechanization technology

Mechanized returning to the field can reduce the amount of chemical fertilizer applied, help to improve the soil, fertilize the soil, and also help protect the environment. The suitable straw returning mechanization technology is to install a straw crushing and dispersing device on the combine harvester, crush the straw after threshing, evenly spread it in the field, and then bury it into the soil. Second, use the 1GF series reverse smashing machine to smash the wheat stalk or The rice bran is crushed and buried in the soil.

2 Straw silage mechanization technology

The silage straw is isolated from the air and subjected to anaerobic fermentation, which can effectively preserve the fresh and nutritious components of the green straw and improve the feeding value. It is an ideal method for preserving green and green feed. Mechanized silage is made by crushing the harvested corn stover with 9Z series silage mower or directly into the silage of silage tower, silage silo, silage pile and silage bag with MB-220 corn silage machine; 9KYQ series round bale can also be applied. The strapping machine and the 9BM series laminating machine are made into bale silage. At present, corn stalks and sweet potato vines are most suitable for silage. The promotion of this technology is of great significance to the development of animal husbandry.

3 Straw ammoniation mechanization technology

Wheat straw is mechanically chopped, chemically and biologically treated, and is a good feed for livestock. When the ammoniated wheat straw feed is used, the straw is smashed with a 9Z series mower or a 9R series reeling machine, and then placed in a storage tank. The prepared urea solution is sprayed in proportion to each 30 cm, and evenly mixed with the wheat straw and compacted. . If the 9SA-600 straw ammoniating machine is used, the prepared urea solution is first added to the medicine box. After the start-up, the chopped wheat straw can be evenly mixed with the solution, and directly sprayed into the storage tank, and each shop is spread 20 to 30 cm. Level one time. When the treated wheat straw exceeds the mouth into a parabola, it is fully pressed with a practical plastic film to be capped, and finally pressed with wet soil.

4 Straw compaction mechanization technology

Mechanized straw briquettes are made of 9YK series straw feed briquetting machine to add crop feed additives (with or without additives) to high-quality and high-pressure roughage products under high temperature and high pressure. The product has the characteristics of small feeding loss, large volume compression ratio, convenient storage and transportation. Suitable for feeding cattle and sheep.

5 Straw baling mechanization technology

Wheat straw can be used as raw material in the paper industry, but it is difficult to transport loose grass, low efficiency and high cost. To this end, it is a good way to put the harvested wheat straw into a square bale and then send it to paper companies everywhere. The wheat baling machine can automatically complete a series of operations such as picking, baling, baling and bundling of wheat straw. The main models are SWB and 9KF series square balers. It is also possible to use the YD-220 fixed hydraulic baler to establish a straw processing plant, and to sell the wheat straw in the local area for sale, with good economic benefits.
