Detailed Explanation of the Bark Grafting Method and Key Operation Points

For bark grafting, cut off the rootstock at 10 to 20 cm above the ground, remove the branches, and select and keep a straight, flat branch surface of 3 to 4 cm. On the side with thicker bark, make a vertical cut 3 to 4 cm long from top to bottom, reaching deep into the xylem. Cut the upper end of the scion flat at 0.5 cm above a bud eye or fruiting spur, and at the lower end, on the side opposite the bud eye or fruiting spur, make a downward slanting cut into a straight, flat, horseshoe-shaped grafting surface 2.5 to 4 cm long. Then shave off the bark 3 to 4 mm on the back side of the scion tip. Press the horseshoe-shaped cut surface of the scion against the xylem of the rootstock incision, align the tip with the rootstock slit, insert the scion and fit it squarely, leaving 1 to 2 mm of the upper part of the scion cut surface exposed. Bind and wrap tightly with grafting film.
