Pulling wire shaping is to correct the opening angle and position of the main branch by mechanical method: if the angle of the main branch is small, tie it with plastic tape or hemp rope, or support a small stick between the two branches to make the angle larger; Individual branches with large angles are hoisted with plastic belts or twine; If several main branches are inclined to one side of the crown, pull them apart and make them evenly distributed. The angle of branches should be extended to 45 degrees with the trunk. The time of pulling the wire is when the new buds germinate for the first time after planting. At this time, the branches grow thicker and faster, and the branches are shaped faster after being pulled. The pulling time should not be too late, at the latest when the new tip is 5 cm long, otherwise it will bend the new tip. Generally, the angle can be above 45 when pulling, and when the new bud is mature, it will loosen and make the branch return to 45. (2) Pruning in the young tree period.

Mainly light cutting. After selecting the extension branches of each main branch and auxiliary main branch, moderate to severe pruning is carried out, and the growth potential balance between main branches is adjusted in the pruning direction. Cut the remaining branches lightly to avoid excessive thinning and re-cutting. In addition to properly thinning the dense branches, the inner cavity of the crown and the middle and lower branches should generally be retained. At the same time, cut off the long branches that are not positioned, so as not to interfere with the crown.
