What are the methods of branch grafting
Today, I will explain in detail the methods of branch grafting and the introduction of three types of family branch grafting methods for green plants and flowers. The following editor will give you a detailed explanation.
Splice grafting: Select one-year-old branches 5-7cm long, retain 2-3 buds on the branches, cut into oblique surfaces, cut the rootstock 5cm from the ground and cut longitudinally, align the cambium layers, and wrap the wound with plastic wrap.
Cleft grafting: Suitable for thicker rootstocks, scions are 5-7cm long with 2-4 buds, the lower end is cut into a wedge-shaped oblique surface, the rootstock is retained for 3cm and cut longitudinally in the middle, then insert the scion into the rootstock.
Abdominal grafting: Retain the branches on the rootstock, cut the bark at the grafting site, insert the scion into the rootstock, and wrap the incision.
I. Branch grafting
Branch grafting is a grafting method using branches as scion material, including splice grafting, cleft grafting, and abdominal grafting. Branch grafting uses a section of a branch from the mother tree, and the branch must have 1-3 buds. The base of the branch is cut to fit closely with the cut surface of the rootstock, and then the scion is inserted into the cut of the rootstock. It is important to align the cambium layers and tie the plastic bag well.
II. Branch grafting methods
Splice grafting: One-year-old branches should be selected for splice grafting, with a length of 5-7cm, and 2-3 buds should be retained on each section of the branch, and the lower end should be cut into an oblique surface. When dealing with the rootstock, it should be cut 5cm from the ground and then cut longitudinally, the size of the cut should be the same as that of the scion's cut, ensuring that the cut surface is smooth enough, align the scion cut surface with the cambium layer of the rootstock, and wrap it with plastic wrap to prevent the wound from contacting moisture and to keep it moisturized. This method is commonly used for plum blossoms and peaches.
Cleft grafting: Cleft grafting is a common method, suitable for relatively thick rootstocks, often used for magnolias and dragon-claw sophoras. The scion length is 5-7cm, with 2-4 buds on top, the lower end of the branch is cut into a wedge-shaped oblique surface, the lower part of the scion is cut to retain about 3cm high, and the middle position is cut vertically, the length of the cut should be longer than the scion cut surface, and then insert it into the rootstock, aligning the cambium layers.
Abdominal grafting: Abdominal grafting is mainly applicable to the grafting propagation of five-needle pines, dragon cypresses, and true cypresses. When grafting, the upper branches of the rootstock can be retained without removal, the bark at the grafting site is cut open with a sharp knife, the scion is inserted into the bark of the rootstock, and the incision is tied up.
