Grafting technique points of apple tree in autumn

1. Branching objects and time: Branches with less perennial results and less prone to drooping afterwards, and those with strong lignified woody branches or strong fruit buds. It can be diverted throughout the growing season. Strictly speaking, it is divided into three times, ie before and after budding, mid-May to mid-June and mid-August to mid-September.
2. Branching position and angle: In addition to the branching of 30 to 50 centimeters for each branch, generally, as long as the branching is adopted at the strong and weak junctions, the ideal branching effect can be obtained when the branches are divided into branches. In general, by turning the strong twigs 180 degrees, the surface of the blade can be turned into a subsurface.
3. Diversion method: Turn to the branch from the base, which side has space, turn to which side; for upright or side branch too thick branches, can live from the base of all sides, and then use the left thumb to follow the branches up Grab the outside of the diverted branches, and hold the other four fingers at the base, about 1 foot from the base. Use your right thumb to move down the branch and hold it against the left thumb, and hold the other finger to transfer it. The waist, both hands at the same time force, rotate in the same direction, while pressing down firmly clockwise rotation, the pressure angle is 90 ~ 120 degrees, the rotation angle is 180 degrees, you can turn straight branches into a half Pendular. If the right hand is down, turn it counterclockwise until it is half sagged. From the base to the branch, it is necessary to achieve the continuous effect of splitting the base. In the course of the transfer, when the sound of a light and brittle gong was heard and a 3 to 5 cm shear crack appeared at the base, the branching effect was achieved.
4. For oblique branch, from 15 to 25 centimeters from the base, once every 15 to 20 centimeters for a branch, turn to semi-sided or semi-pendulous; for the former strong after the weak branch, you can from strong Weak transfer at the transfer branch, turn to the position of the yin and yang can be exchanged.
