1. The saplings in the garden: the upright main branch and the leggy branch of the prosperous branch of the main branch and the main branches of the main branch are removed from the trunk and the branches and branches on the main branch are opened. Mainly. The main branch opening angle of 60-70 degrees is appropriate, the side branch opening angle of 70-80 degrees is appropriate, pull the stick to pull into a line, avoid drawing into a bow.
The sprouting is generally performed before the sprouting of the bud in the middle or late March. For the purpose of triggering the lateral branching on the main branch, the two sides of the bud are carved at a certain distance, and the depth of the budding is greater; for the purpose of promoting the flower on the lateral branch, it is necessary to Both sides of the bud are engraved and the depth can be lighter.
2. The early fruit tree (4-7 years old): It is necessary to adjust the structure of the tree, the cultivation of the result branch on the main branch, and the results at the same time. First, gradually eliminate excessively low and dense main branches, so that each main branch does not affect each other; second, appropriate retraction of main branch extension branches without branches (lateral branches) to promote branching. The third is to retreat or rejuvenate the weak side branches, to open the perspective of excessive prosperity, ease growth and promote flowering.
3, full fruit period tree: adjust the structure of the tree, improve the scenery conditions within the crown, rejuvenate the growth of the backbone, maintain and rejuvenate the results of the results of the results of the Zhizu group, prolong the full fruit period.
(1) Adjustment of tree structure: For large branches that seriously affect the light and auxiliary branches that are ineffective, extra erection branches, dense branches, overlapped branches, cross branches, etc. in the crown must be drowned out, and the layers should be opened to avoid disturbances. Tree shape, consume nutrition. The tree was over-high and promptly fell to be happy. The weak branches took the lead and controlled the height of the tree crown.
(2) Pruning of backbone branches: Light and short cuts can be made on the main branch extension branches that thrive. For the main branch extension of the golden mean, if the annual growth does not exceed 20 cm, it does not need to be short. Those who are weak and incompetent should be moderately shrunk. For those who have had prosperous and erect perennial branches and broomsticks on their backs, they should be removed from the base in a timely manner.
(3) Results Pruning of branches: In the canopy of branches, flower clusters, and weakly growing short fruit branches, measures are taken to retreat from weakness, stay strong, cut more and less, raise the angle, and strengthen the branches to take the lead. Rejuvenate. For the result of the strong ramifications, it is necessary to stay strong and weak, to stay straight, to gently cut and slow down, to ease the trend. For the Zhongyong branch group, there must be a cut-off, so that the Zhizu group will always maintain its strong and healthy growth.
