2. Pull the branch object. Suitable branch stage index: the suitable branch stage of medium density garden is above branch length 1m and base thickness 1cm, which should not be too early. Pulling it out too early will easily cause the tree to weaken and form a "small old tree".
3. Angle of branch pulling. For orchards with medium density, the types of branches must be distinguished when pulling branches. For the backbone branches that need to be permanently preserved, the bottom angle can be drawn to 85-90, and the backbone branches are inserted every 20cm and selected to be kept in a spiral arrangement, and 15-20 four-year-old trees can be selected to be kept.
4. direction of branch pulling. We should not only pull down vertically, but also consider the space near the tree body, adjust the branch angle, especially the direction of the main branch. The upper and lower branches should be evenly arranged, and the arrangement should be reasonable, not overlapping and crossing, and staggered and wavy.
