A kind of degradable mulch film adapting to different environments and its manufacturing method

Abstract

The invention discloses a degradable plastic film adapted to different environments, comprising a rapidly degradable plastic film layer, a soil treatment layer and a slowly degradable plastic film layer. It is arranged between the rapidly degradable mulch layer and the slowly degradable mulch layer to form an interlayer, and relates to the technical field of mulch. The degradable mulch film and its production method adapted to different environments achieve the degradable effect of the mulch film. After the crops mature, there is no need to manually recycle the mulch film. The mulch film can be covered with the ground by a tiller, and the mulch film will decompose itself without affecting the next time. The planting of crops does not damage the soil and achieves an environmental protection effect. At the same time, after the film is laid, the film layer will be degraded quickly, so that the soil treatment particles in the soil treatment layer enter the soil, which can improve the acidity and alkalinity of the soil. It makes the soil more suitable for plant growth, and at the same time provides certain fertilizer for plants.

Description

technical field [0001] The invention relates to the field of mulch technology, in particular to a degradable mulch adaptable to different environments and a manufacturing method thereof. Background technique [0002] Mulching films can be divided into two categories: ordinary mulching films and special mulching films according to their functions and uses. Ordinary mulch film includes broad-spectrum mulch film and thin mulch film; special mulch film includes black mulch film, black and white double-sided mulch film, silver-black double-sided mulch film, green mulch film, microporous mulch film, incision mulch film, silver gray (aphid avoidance) mulch film, (chemical) weeding mulch film, color-matched mulch film , Controllable degradation of plastic film, floating film, etc. [0003] Plastic film is often used in agriculture, but it is very difficult to recycle the existing plastic film. After the crops are harvested, the plastic film is often damaged and unusable, but it can...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a degradable plastic film adaptable to different environments and its production method, which solves the difficulty in recycling the existing plastic film, which causes land pollution, is not suitable for re-cultivation of crops, and causes irreversible damage. At the same time, the existing degradable plastic film cannot improve the soil environment, and the problem of poor practicability
