High-efficiency recycling mulching film with controllable full-biodegradation strips on two sides

Abstract

The invention discloses high-efficiency recycling mulching film with controllable full-biodegradation strips on the two sides. The high-efficiency recycling mulching film with the controllable full-biodegradation strips on the two sides is composed of the two controllable full-biodegradation strips and a polyethylene strip in an alternate mode, wherein the controllable full-biodegradation strips are arranged on the two sides respectively, and the polyethylene strip is arranged in the middle. According to the high-efficiency recycling mulching film with the controllable full-biodegradation strips on the two sides, due to the facts that the middle portion can be easily recycled, and the portions embedded into the ground can be completely biodegraded in a controllable mode, the recycling rate of the mulching film is improved, and pollution caused by residual film is reduced; in addition, moisture infiltration in the later growth period of crops can be improved, influence caused by the high temperature is reduced, the requirements of the crop for different temperatures and different levels of moisture in different growth periods can be met, and thus the yield and quality of the crop can be improved.

Description

technical field [0001] The invention relates to the field of materials, in particular to a fully biodegradable plastic film with both sides controllable and efficient recovery. Background technique [0002] Ordinary polyethylene mulch degrades very slowly. Long-term use will not only cause soil pollution and environmental pollution, but also a large amount of residual film will remain in the soil and affect the growth of seedlings and root systems, which is detrimental to crop growth and yield. In order to reduce the adverse effects of ordinary polyethylene film residues on the soil and the environment, people began to pay attention to the recycling and reuse of ordinary polyethylene film. However, in the recycling process, the part buried in the soil is difficult to recover, or only a small part can be recovered. If both sides are degradable, the recovery rate of polyethylene mulch can be improved and the pollution of residual film can be reduced. Contents of the inventi...
