Problems solved by technology

After the crops are harvested, the plastic film left in the soil after a certain period of time is exposed to the wind and the sun. It is difficult to completely recycle the plastic film, and it is impossible to realize the mechanization of plastic film recycling, resulting in huge white pollution. After many years of continuous cultivation, the soil is hardened due to the residue of the plastic film , has caused great land pollution and environmental pollution

Embodiment 1

[0025] Embodiment one: if figure 1 As shown, the mulch film that is easy to recycle includes a mulch film body 1, and the mulch film body 1 is provided with opening slits 2 corresponding to the covered crop planting rows 4 along the length direction.

[0026] Such as figure 2 As shown, the opening slits 2 in this embodiment are elliptical holes arranged at intervals along a straight line. Of course, as ordinary engineers and technicians in the field, according to the technical inspiration of the present invention, it can be deduced without doubt that the opening seam 2 can also be a round hole, a tear line or a tear mark. The lines are slits arranged at intervals, and the tear marks are cuts or indentations that do not go through the mulch. The opening slit 2 is required to be able to meet the horizontal tensile force in the film width direction during the film covering process, and to ensure that the film will not be broken by the wind after film covering. The special fi...

Embodiment 2

[0028] Embodiment two: if Figure 4 As shown, the plastic film of this embodiment is wound on the plastic film roller 3, and the plastic film can be uniformly made with two opening slits 2 along the longitudinal direction in the film making or film covering process according to the planting density of the crops. Of course, it can also be Make multiple opening seams 2 as required. In this embodiment, the opening seam 2 has tear lines arranged at a certain interval, and the tear lines are required to be able to meet the horizontal tension in the film width direction during the film covering process, and to ensure that they are not damaged by wind after film covering. blow out. The mulching film in this embodiment can be applied to crops covered by double rows, such as peanuts, garlic and other crops that need to be covered with a film to preserve moisture.

[0029] According to the technical inspiration of the above embodiments, the opening seam 2 of the present invention can ...

Abstract

The invention discloses a mulching film convenient to recover. The mulching film comprises a mulching film body, wherein opening seams which correspond to covered crop planting rows are arranged along the length direction of the mulching film body. The mulching film has the advantages that the film can be separated along plant rhizomes easily and is easy to recover; the film is separated through the opening seams during film recovering and plants are not damaged; the film-picking operation is not required to be conducted for seeds which are planted along the opening seams, seeds can sprout and are out of the film and the labor is saved; the mechanical film recovery is facilitated, the efficiency is improved, and the cost is reduced; the mulching film can be recovered completely and no residue exists; and the problem that the soil is hardened due to the residual mulching film is solved, the agriculture can develop efficiently and sustainably and the white pollution is solved completely.

Description

technical field [0001] The invention relates to a field covering film, in particular to a field covering film used for the early growth of crops. Background technique [0002] Film mulching cultivation technology can improve the temperature and moisture status of the soil and near the ground, increase soil temperature, maintain soil moisture, improve soil properties, improve soil nutrient supply and fertilizer utilization rate, improve light conditions, and reduce weeds and pests. hazards etc. The vigorous development of mulching technology has enabled China, a traditional agricultural country, to embark on a road of high and stable agricultural production, and has made a significant contribution to China's economic development. [0003] Such as Figure 7 As shown, the basic method of plastic film covering is to cover the film along the length of the ridge. During the film covering process, the plastic film should be tightened, and the two sides of the plastic film should b...
