Splitting method

It is mainly carried out in spring when the buds are sprouting and before germination. When grafting, first cut the rootstock at the grafting site, then cut the damaged surface, and then cut a vertical cut in the middle. When cutting scions, select a section with about 2-4 buds, cut a 3-4cm long cutting surface on both sides of the lower part, and cut from a place about 1cm away from the lower bud to avoid damage to the lower bud. The cutting surface should be slightly thicker on the outside and slightly thinner on the inside. After cutting, the outer side is the thick side, and the thin side is facing inward. Insert the scion into the cutting edge of the rootstock. The formation layers of the scion and the rootstock must be aligned. At the same time, pay attention not to insert all the cut surfaces, but about half a centimeter should be reserved, which is conducive to the healing of the wound. According to the thickness of rootstock, 1-2 scions can be inserted. Finally, wrap the interface with plastic strips to reduce the evaporation of water

T-shaped budding method

T-shaped budding is generally carried out in autumn. The grafting process is as follows: firstly, select the smooth and scar free part on the windward side of the rootstock in spring at the position about 5cm above the ground, first cut a "t" shaped incision, and then cut the bud on the scion. When cutting the bud, first cut the xylem from the lower part of the bud about 1.5cm with a knife, with a longitudinal cutting length of about 2.5cm, then cross cut from the upper part of the bud about 1cm, and then hold the bud with your hand and break off the bud piece. When inserting buds, first open the "t" shaped interface with the bud connecting knife handle, gently insert the bud piece from top to bottom, align the "t" shaped incision above the bud piece, and finally bind it with a plastic strip with a width of about 0.5-1 cm from bottom to top

Skin joint

This method is also called subcutaneous connection. First, at the grafting site, select a smooth place without wound to saw off the upper part of the rootstock, and use a knife to flatten the damaged surface, and then select the scion, which is suitable for a section with 2-4 buds. With the scion in one hand and the knife in the other hand, cut a cut surface with a length of about 3-5cm at the lower part of the other side of the top bud, then cut a short cut surface with a length of about 0.6cm at the tip behind the long cut surface, and then cut a vertical cut of about 2cm at the insertion position on the rootstock, and then insert the cut scion so that the long cut surface is inserted inward, paying attention to appropriate blank. Finally, tie it tightly with plastic strips

Bud embedding grafting

It is also called budding with wood. This method is convenient and simple, has high survival rate, and can be grafted in four seasons. The specific operation methods are as follows:
