The age of longan trees with low grafting can be long or short, but it is best to choose young and middle-aged trees under 10 years old from the point of view of easy operation.

3. Rootstock selection

For young and middle-aged longan trees under 10 years old, grade 1 or 2 oblique backbone branches can be selected as grafting rootstocks, and the branch diameter can be about 3 ~ 10 cm. Usually, 3 ~ 5 rootstocks are selected for 3 ~ 5-year-old trees, 5 for 6-year-old trees and 3 for 9-year-old trees.

4. Grafting method

① grafting incision: use a branch knife to cut a 1.5 cm cut parallel to the rootstock on both sides of the saw blade of the rootstock, reaching to the xylem, twisting the knife edge slightly toward the xylem, and then quickly loosening the grafting knife, that is, the grafting interface.

② cut the scion: the scion length should be 5cm / 6cm, the upper end should have 1 / 2 full axillary buds, the lower end should be cut into a 45-degree fracture with the scion, and the lower fracture surface should be cut into a long cutting surface similar to the cut length of the rootstock, reaching to the xylem, and the fracture and cutting surface should be smooth.

③ insert interface: put the fracture under the scion toward the rootstock, face the interface, and insert gently along the interface, its long cutting surface is close to the bark and pressed by hand at the same time.

④ interface fastening: first tie the interface with a special plastic film for grafting, and then wrap the rootstock and scion, and the axillary buds of the scion should be covered with single-layer film.

⑤ spraying against insects: sprinkle insecticidal and clear powder on the interface and the saw of the rootstock to prevent insects and ants from biting through the film.
