Chestnut balance stunt trimming skills

The author has repeatedly told chestnut farmers about chestnut management techniques, and found that many chestnut gardens have many problems, especially the uneven distribution of main and lateral branches and various branches and groups, which can not maximize the use of space, resulting in stronger and stronger branches. Oblique crown closure is severe, and weak branches are getting weaker and weaker. There is no space available and production is seriously hindered. In response to this problem, the author adopted a pruning method that balances the tree potential and achieved good results.

1. Main branch balance (take three main happy shapes as an example). The main branch is the main skeleton that supports each branch. Before trimming, first look carefully at the position and growth of the three main branches, so that you can make adjustments in your mind. For the strong branch (brightness ratio) of the main branch, strong pull a large angle, but also the side branch to replace the main branch extension head, combined with peeling, appropriate more fruit, fruit pressure crown; for a strong main branch, appropriate opening angle , Appropriate leave fruit; For the weaker main branch, dredging weeping branches, raising the angle, leaving little fruit, at the same time, but also the main branch at the base of the cortical injure, properly prevent the transfer of nutrients to other strong branches, make Rejuvenate.

2. Collateral balance. Lateral branches are the limbs that support the resulting branch and the use of space on the main branch. The robust growth of a tree, the balance of the lateral branches is also very important. Similarly, for the side branches that compete with the main branch, it is necessary to pull the branches downwards and keep more fruits; for the weak side branches, they should be retracted in time to allow them to rejuvenate.

3. Results Branches balance. The balance of the branch is the key to good fruit and yield. For weak branches, we must go weak and stay strong. Weaknesses must be promptly retracted to good branches. No good branches should be returned to the buds, and branches should be promoted. After many times in the summer, the hearts will be re-cultivated. Result sticks. For strong fruiting branches, we must maintain a consistent group of mean trees, go to the strongest and weakest branches, and cut short some Zhuangzhi groups as a result of the leap year. In this way, the nutrient supply is balanced, the distribution is reasonable, the results are even, the quality is good, and the yield is high.
