Abstract

The invention discloses a multicolor mulching film which comprises two double-color mulching films and a light-colored mulching film. The light-colored mulching film is arranged between the two double-color mulching films and is connected with the two double-color mulching films, and the double-color mulching films are composite films comprising silver grey mulching film layers and black mulching film layers. The invention further provides a method for preparing the multicolor mulching film. The multicolor mulching film and the method have the advantages that the multicolor mulching film has merits of the double-color composite mulching films and the light-colored mulching film, accordingly, effects of preserving moisture of soil and inhibiting growth of weeds can be realized by the double-color composite mulching films for crops in cultivation procedures, effects of increasing the temperatures and preserving moisture can be realized by the light-colored mulching film for the crops in the cultivation procedures, the multicolor mulching film is favorable for optimal growth of the crops, the crops can be ripen in advance, and the yield can be increased; the multicolor mulching film is high in ageing resistance and long in service life and is easy to clean and recycle after being completely used, accordingly, land pollution can be abated, and the multicolor mulching film and the method are economical and environmentally friendly.

Description

Technical field [0001] The invention relates to the technical field of agricultural plastic products, in particular to a multicolor mulch film and a preparation method thereof. Background technique [0002] Mulch is a ground cover film used for ground cover to increase soil temperature, maintain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, and promote plant growth. [0003] At present, the mulching film has developed from ordinary mulching film to a variety of monochromatic mulching film (such as black mulching film, white mulching film, single colored mulching film), black and white mulching film and composite mulching film (such as silver-gray black composite mulching film). [0004] Among them, the black mulch film has a low light transmittance and heat is not easily transferred to the soil, so it has a relatively strong performance in preventing soil water evaporation and can significantly inhibit the gr...
