▎ 摘　　要

NOVELTY - Preparing accelerating agent based on graphene, comprises (a) using water as a solvent, adding graphene oxide for ultrasonic treatment, allowing to stand for processing to obtain upper layer solution, and drying and ultrasonically treating to obtain graphene oxide; and (b) dissolving the ultrasonically treated graphene oxide in water, stirring uniformly, adding aminated nano-silver, and reacting at 50-60℃. USE - The accelerating agent based on graphene is useful in promoting the germination of Codonopsis pilosula seeds (claimed). ADVANTAGE - The accelerating agent effectively promotes the germination and growth of Codonopsis pilosulaseeds. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: accelerating agent based on graphene, prepared as mentioned above; and promoting seed germination of Codonopsis pilosula, comprising dispersing the graphene-based Codonopsis seed germination accelerating agent in water and stirring evenly, adding Codonopsis seeds and soaking at room temperature for 3-4 hours.
