Protector for plantation grafting of agricultural commercial fruit trees

The invention discloses a protector for plantation grafting of agricultural commercial fruit trees. The protector comprises a protection plate, the top and bottom of the back of the protection plate are glued to rubber gasket blocks respectively, the two end surfaces of the back of the protector are bonded to sealing gasket blocks respectively, fixed bands are symmetrically installed in one side surface of the protection plate, and integrating blocks are arranged in the back end surface of the fixed bands at equidistance. The protector is scientific and reasonable in structure and safe and convenient to use, the protection plate covers the grafting position in a trunk of a fruit tree in vivo, and thus protects the grafting branches and buds against interference and loss of activity, the rubber gasket blocks and sealing gasket blocks realize simple sealing, the outside air flow is avoided from entering a space covered by the protection plate, the internal temperature of the space is avoided form influence of t
