1, coring. In summer, if the selected secondary branches grow excessively, they can be picked when the secondary branches are not lignified to promote branching and cultivate fruiting branches.

2. Shortcuts. Cutting developing branches without removing core can effectively increase branches, speed up the shaping process or the culture process of fruiting branches, but the number of new shoots should not be too much, and the parts should be staggered, otherwise the branches will easily overlap.

3, thin branches and long branches. When the growth position of long branches is unreasonable and the growth potential is different from that of adjacent main branches and lateral branches in the same direction, they should be drained from the base, or kept properly according to their spacing, and cut short and cored in summer to cultivate fruit branches.

4. release. For new shoots with moderate growth, it is not advisable to pick the top or lightly cut the top. The lighter the pruning, the more fruit branches and the less secondary branches.

5. Pull the branches. Timely branch pulling can open the opening angle of walnut trunk branches, make full use of crown space, promote flowering and improve fruit setting rate.

6. Pick up branches and take branches. Soften and shape the branches, then tie ropes to pull the branches or hang bags, bottles and bricks to press the branches, change the angles of the branches, and put the branches in proper positions.
