1, about 40 ~ 50 cm in the first year.

2. In the second year, three new shoots with strong growth and suitable direction were selected as main branches. The base angle is 50 ~ 60, and it is evenly distributed in the direction of about 90 ~120. Each main branch leaves 3 ~ 4 lateral branches on the anticline side, and more branchlets are left on the lateral branches of the main branch. The distance between the main branches of this tree is reasonable, and the crown coverage rate is about 80%. The canopy is ventilated and transparent, with few long branches and three-dimensional fruit hanging. From June to July, after the new branches are lignified, use brown rope or hemp rope to pull the branches (plastic rope is elastic and ineffective, so it is best not to use it) to ensure the bottom angle of 60 ~ 70.

3. In the third year, the main branch extends outward, and lateral branches are cultivated at a position 40-50 cm away from the base of the main branch, and 3-4 lateral branches are cultivated for each main branch, and the lateral branches are staggered on both sides of the main branch.

4. In the fourth year, the trees are cultivated, and all the ropes for pulling branches are hoisted to form fruiting branches.

5. Pruning time is 65438+ from February to February and from May to August every year. Pruning in winter is mainly based on thinning branches, focusing on thinning pests, competitive branches, drooping branches and cross branches.
