▎ 摘　　要

NOVELTY - The sheet has a first insulating layer (2) and a second insulating layer (3) arranged integrally to form a cavity (6) that accommodates a graphene heating layer (1), where distance between the peripheral edge of the graphene heating layer and corresponding peripheral edge of the cavity is bout 2-4 cm. The graphite heating layer is provided with two electrodes (7) for connecting the positive and negative electrode of an external power supply. A first negative Oxygen ion layer (4) and a second negative Oxygen ion layer (5) are fixed with a base layer. A PU layer is connected with a negative Oxygen ion layer. USE - Graphene far infrared negative oxygen ion heating sheet. ADVANTAGE - The sheet has better insulation performance, can release far infrared ray and negative oxygen ion, and improves air quality in greenhouse so as to promote growth of plant root and reduce usage amount of occurrence and pesticide of plant diseases and insect pests, thus improving quality and yield of vegetables. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene far infrared negative oxygen ion heating sheet manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a partial sectional view of a graphene far infrared negative oxygen ion heating sheet. Graphene heating layer (1) Insulating layers (2,3) Negative Oxygen ion layers (4,5) Cavity (6) Two electrodes (7)
