Detailed Explanation of the Cut-Grafting Method and Operation Steps

The cut-grafting method is used for own-rootstock and wild jujube rootstock; its survival rate is not as good as that of the whip-and-tongue grafting method. Used on Chinese hackberry (Celtis sinensis) rootstock, the survival rate is very high, and the method is relatively simple. When cut-grafting, cut the rootstock at 10 cm above the ground, then make a vertical downward cut on one side of the cut surface, with length and width roughly close to the cut surface of the scion. On the scion, at the underside of the bud eye or the fruit spur, make a downward slanting cut into a smooth 3 to 4 cm long graft surface, with the tip of the graft surface reaching the pith. Then, on the back side of the tip of the graft surface, make a short slanting cut at an angle of about 30 degrees, about 1 cm long. When joining the rootstock and scion, the cambium layers of the rootstock and scion must be aligned evenly, with the upper part exposed by 2 mm, and wrapped and bound tightly.
