Camellia oleifera tree top grafting and crown changing moisturizing structure

The utility model discloses a camellia oleifera tree top grafting crown-changing moisturizing structure which comprises a bud ear piece and a thin film block, the bud ear piece is bound to a camellia oleifera tree crown-changing grafting position through a binding belt, the thin film block wraps the periphery of the bud ear piece to form a sealing structure, and the moisturizing structure further comprises an inflation portion which inflates air into the sealing structure defined by the thin film block. Compared with the prior art, an electric adhesive tape is adopted, so that the sealing effect is better, a sealing structure in the prior art leaks air quickly, and the sealing structure can be seriously deformed and leaks air after being inflated for 3-5 days at most; after the structure is adopted for inflation, air leakage can be kept for 20-30 days. Water vapor in the sealing structure is more sufficient, high humidity can be kept for a long time, the sealing structure is good in sealing performance and su
