Agricultural mulching film of reinforced composite structure

Abstract

The invention belongs to agricultural mulching film structure innovations and particularly relates to an agricultural mulching film of a reinforced composite structure. Film edge reinforced areas are arranged on two sides of a mulching film basal body respectively, sowing row areas and middle reinforced areas are distributed on a mulching film between the two film edge reinforced areas uniformly and alternately, composite mulching films in the film edge reinforced areas and the middle reinforced areas are reinforced mulching films, the mulching film basal body and mulching films in the sowing row areas are common mulching films, and the spacing among the sowing row areas corresponds to the sowing row spacing in a field. The agricultural mulching film of the reinforced composite structure is high in integral strength and wind resistance, less prone to breakage, long in service life, low in production cost and good in light-transmitting and heat-insulation performance, and mulching film laying and waste mulching film recovery can be achieved mechanically.

Problems solved by technology

[0002] It has been many years since the development and application of plastic mulch to cover crops on the ground. Now this technology is indispensable in agricultural production. Further stretching in the longitudinal direction makes the film thinner and the physical strength is not enough

Unreasonable use methods, such as over-recovering soil on the mulch to resist wind disasters

The quality of mulch film is generally poor. If the service life is short, the effective use period of the mulch film is set to be shorter when the mulch film is produced. The mulch film has lost its original physical and chemical properties or original The retention rate of the physical and chemical properties of the material is already very low

These factors lead to the poor ability of the ordinary mulch film in use to resist wind disaster damage during use, the surface of the seed bed film has a lot of compound soil, the lighting surface is relatively small, and the mulch film is difficult to recycle, resulting in serious pollution of the farmland column film, which has a great impact on the agricultural ecological environment. Great harm, affecting agricultural production

Due to the imperfection of the technical process, the currently developed dry-type compound reinforcement mulch has high production costs and low production capacity.
