▎ 摘　　要

NOVELTY - The cloth has a bottom layer (1), a surface layer (2) and a graphene electric heating film (3) that is located between the bottom layer and the surface layer. The wires (4) are connected to the graphene electric heating film. A controller is configured for controlling the power-on and power-off of the graphene electric heating film. The graphene electric heating film includes a metal current-carrying strip, a conductive ink containing graphene and an insulating polyester film, where the bottom layer and the surface layer have a convex structure in regions where the bottom layer and the surface layer do not correspond to the graphene electric heating film. The bottom layer is calcium-magnesium acupuncture fiber membrane. The polypropylene grass-proof cloth is woven from multiple polypropylene flat yarns. USE - Gardening ground cloth. ADVANTAGE - The graphene electric heating film is electrified to generate heat to supply heat for the crops in the shed when there is no need to supply heat. The graphene electric heating film is controlled to power off to achieve controllable temperature in the shed. The graphene electric heating film has low power consumption, saves energy, and graphene electric heating film can release far infrared ray to promote the growth of crops. The bottom layer and the surface layer are distributed with convex structure in the area where is not corresponding to the graphene electric heating film, thus enhancing air flow property of the horticultural ground cloth, so as to enhance ventilation property. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a gardening ground cloth. Bottom layer (1) Surface layer (2) Graphene electric heating film (3) Wire (4)
