Grafting method of subcutaneous grafting

Subcutaneously cut off the rootstock 10 to 20 centimeters above the ground, remove the branches, and leave a straight branch surface of 3 to 4 centimeters. On the thick side of the cortex, the interface is cut 3 to 4 centimeters from top to bottom to reach the xylem. The upper end of the scion is trimmed 0.5 cm above the bud or jujube, and the lower end is obliquely cut downward into a Maltese-shaped straight interface on the back of the bud or jujube, 2.5 to 4 cm long. Then cut off the 3 to 4 mm cortex on the back of the scion, stick the Maltese-shaped cutting surface of the scion to the xylem of the interface of the rootstock, insert the cutting seam of the rootstock into the scion and fit it properly, and the upper part of the cutting surface of the scion is exposed 1 to 2 mm. Wrap it tightly with a film.
