▎ 摘　　要

NOVELTY - The seedling bed comprises a supporting mechanism (3). A thermometer (1) is installed on the sidewall of the supporting mechanism. Multiple seedling raising mechanisms (4) are slidably connected to the inside of the supporting mechanism. A heating mechanism is fixed to the inside of the supporting mechanism. The heating mechanism includes a fixed tube, a cylinder, a graphene heating film, a compression rod, a rubber pad, a spring, and a limit rod. Multiple cylinders are installed inside the support mechanism, and the fixed pipes are symmetrically installed at the bottom of the cylinders. The inside of the rubber pad is slidably connected to the limit rod, and the sidewall of the limit rod is sleeved with the spring. The drive mechanism (2) is installed inside the support mechanism, and the sidewall of the drive mechanism is installed with the compression rod. USE - Seedling bed based on graphene heating. ADVANTAGE - The seedling bed keeps the dendrobium growing in winter and reduces the seedling time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for raising seedlings based on graphene heating involves putting multiple seedling raising plates into the support column. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the seedling bed.
