Description

Small-size cotton field broad film double-ditch residual film recovery device

Technical Field

The utility model relates to an agricultural equipment technical field especially relates to a incomplete membrane recovery unit of small-size cotton field broad film double flute.

Background

The plastic film mulching technology was invented by Japanese scientists in the 50 th 20 th century, and was introduced into China in the end of the 70 th century, and has been popularized and applied to various crops in the 80 th. The mulching can remarkably improve the crop yield and the water utilization efficiency, can keep a good soil structure, can inhibit soil salt return, reduce the spread of diseases along with water, inhibit weeds and plant diseases and insect pests, and save the input of pesticides, fertilizers, irrigation water and labor; it can also increase temperature and preserve soil moisture, adjust the seeding and growth period of fruits and vegetables, realize out-of-season production, improve canopy illumination and improve the quality of fruits and vegetables.

After the plastic film mulching technology is introduced into China, the water resource utilization rate and the crop production capacity of arid and semiarid regions are effectively improved, and the crop yield and the farmer income of the regions are increased; plays an important role in guaranteeing national food safety, generates great economic benefit and is known as 'white revolution'. However, with the increase of the amount and the expansion of the application range, the problem of residual film pollution of farmlands also becomes more serious and becomes a main source of 'white pollution' in rural areas. The common polyethylene mulching film (PE mulching film) is a macromolecular compound and is difficult to degrade under natural conditions. Because the residual film is difficult to recover and has high labor intensity, most farmers use a rake to pick up the mulching film simply and then directly turn small residual films to the underground, the residual film in plough layer soil is accumulated more and more along with the increase of service life, and serious residual pollution is formed in partial areas, thus leading to a series of production and environmental problems.

Aiming at the problem of residual mulching films, agricultural machinery researchers develop various residual mulching film recycling machines, but the residual mulching film recycling machines are large-scale machines, are suitable for large-area operation, and lack special agricultural tools for cleaning residual mulching films in field test cells of one-film double-ditch cotton fields. The technology for cultivating cotton in saline-alkali dry land by one film and two ditches is a new agricultural technology, has the advantages of collecting rain, inhibiting salt, protecting seedling, increasing yield and the like, has very obvious effects of inhibiting salt and increasing yield, creates a new way for obtaining stable and high yield of cotton planting in the saline-alkali dry farming agricultural area, and has the advantages of expanding the model popularization area year by year in recent years. Patent of invention obtained by the technology, patent number: 201510400595.4, the mating seeder has obtained the utility model patent, patent number: 201520927773.4. in the implementation of the one-film double-furrow cotton cultivation technology in the saline-alkali dry land, small ridges with the height of 8-10cm are required to be formed under the film, and the conventional residual film recycling device is difficult to be matched with.
