(1) For T-shaped bud grafting, first make a cross cut 0.5-0.7 cm above the bud, deep into the xylem, then make an oblique cut 1 cm below the bud to the cross-cut edge, and remove the bud piece . When removing the buds, be careful not to tear off the vascular bundles inside the buds. Make a crosswise cut on the smooth part of the rootstock 5 to 7 cm away from the ground. Use the tip of the knife to make a small slit downward in the middle of the horizontal cut. Pry open the bark, insert the shaved buds into the cut, and push down. Align the upper transverse incisions, and finally wrap them tightly with plastic cloth strips, leaving only the petiole bud eyes exposed on the outside. Since the back side of apricot buds is often affected by the small wooden hooks of the vascular bundle, it is difficult to remove all the cambium layer when removing the buds. In addition, after the apricot buds are removed, a recess is often formed on the back of the buds. After being inserted into the interface, only the periphery of the buds are in contact with the stock, while the middle of the bud is difficult to adhere to the stock and forms a "cavity", which will inevitably affect the survival of bud grafting. Rate. (2) Bud grafting with xylem In order to improve the survival rate of bud grafting and carry out grafting while the scion and rootstock are not peeling off, the bud grafting with xylem method can be used. This method is: when cutting the buds, hold the scion upside down, cut it diagonally downward 0.5 cm above the bud, the depth of the knife edge reaches 0.2 cm below the bud, and the length is about 1 cm longer than the bud body, and then cut it diagonally below the bud. The knife reaches as deep as the first shaved surface, so that a bud piece with xylem can be removed. Cut the rootstock 5 to 7 centimeters away from the ground at a downward angle. The shaved surface should be the same length as the shaved surface of the bud piece with xylem. Make another downward and transverse cut at 1/3 to 1/2 of the edge of the knife, and remove the piece of tape. The anvil of the xylem. Insert the shaved bud pieces under the peeled rootstock skin, aligning the upper and lower edges with the rootstock incision. If there is a difference in the size of the scion and rootstock incisions, just align the upper and lower parts and tie them tightly with plastic cloth. Like T-shaped bud grafting, the petiole bud eyes should be exposed when tying the plastic sheet so that the survival rate can be checked 20 days after grafting. Move the petiole with your hand. If it falls off as soon as you touch it, it means that the graft has survived; if it does not fall off when you touch it and the bud turns black, it means that it has not survived.

Budding with xylem can be done not only in summer and autumn, but also in early spring. In other words, bud grafting with xylem is not restricted by season during the growth period. (3) Splicing is usually done in spring. Using the wax-sealed scion, cut a knife along both sides about 3 cm from the base of the scion. After the shaved surface is finished, the shaved scion should be thin on the inside and thick on the outside, wide at the top and narrow at the bottom, forming a wedge shape. The shaved surface should be smooth. Cut off the rootstock 5 to 7 centimeters from the ground (for large trees, you can cut off the branches anywhere on the trunk), and then use a knife to make an incision from the center of the cross section to a depth of about 4 centimeters. Finally, insert the shaved scion into the incision, aligning the skin with the skin of the rootstock. Regardless of the thickness of the scion and rootstock, as long as one side has the cambium aligned. When the scion is inserted into the cut of the stock, 0.2 to 0.3 cm of shaved surface should be left outside the stock to facilitate rapid healing of the joint, which is called "whitening" by the masses. After the scion is inserted, tie the joint tightly with plastic cloth to prevent water loss from the joint.

Cleft grafting can be used in both annual nurseries and large trees. (4) Cutting method The cutting method should also use wax-sealed scions. Cut the base of the scion into two corresponding chamfered surfaces, one chamfered surface about 3 cm, and the other chamfered surface about 1 cm. Cut off the rootstock 5 to 7 cm above the ground (cutting of large trees can be done at any part of the branch), and trim the cross section. Make a straight cut downward along the edge of the xylem, with the length and width of the cut corresponding to the long side of the scion. Insert the scion into the cut and align the cambium. Then wrap the bark of the rootstock cut around the scion, and finally tie it tightly with plastic strips.

The above four methods are simple and easy to implement and are widely used in production. In addition, apricot tree grafting also includes skin grafting (also known as subcutaneous grafting), joint grafting, ventral grafting, tongue grafting, root grafting, etc. Readers can choose to use them according to the actual situation.
