Description

Technical Field

[0001] The invention relates to the technical field of cherry tree planting, and in particular to a method for shaping a cherry tree into an inverted umbrella shape. Background Art

[0002] Cherry trees (especially sweet cherries) are species that require a lot of sunlight. They have dense crowns and fast-growing branches, which can easily cause canopy shading, affect light distribution, and thus affect tree growth and fruit development. In order to ensure light and ventilation, certain pruning measures need to be taken.

[0003] Common traditional cherry tree pruning methods mostly use natural tree shape or trunk pruning. Although this method is simple, the tree shape is not easy to control and it is easy to cause the crown to be too dense, affecting ventilation and light transmission, and thus affecting the quality and yield of the fruit; there is also a hedge-shaped shaping method. The above methods are all flat tree shaping methods. The tree shape is a single-sided structure, which is easy to become strong and difficult to flower and bear fruit. The side branches extend in a single axis, and the fruiting part is easy to move outward, causing space waste. It is not suitable for varieties with strong upright main branches and can only be used for varieties with larger natural opening angles. Therefore, the present application provides a cherry tree drooping umbrella shape shaping method to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the invention is to provide a method for shaping a cherry tree into an inverted umbrella shape to solve the existing problems.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A method for shaping a cherry tree into an inverted umbrella shape comprises the following steps:

[0007] S1. Select healthy plants that have grown for one year after grafting and plant them in the field. Cut the trunk to a height of 90-100 cm from the ground, retain two full buds under the cut, manage water and fertilizer normally for one year, and cultivate two strong main branches.

[0008] S2. Before budding in the spring of the second year, the two main branches were pulled and fixed with steel wires at a height of 2.2-2.3m, extending to both sides, and the buds on the back were erased. The bud activation technology was applied to the buds on the back and both sides;

[0009] S3. Pull down and fix the newly grown side branches on the two main branches to both sides of the main branches, so that the angle between them and the ground is greater than 70°, the spacing between the side branches is 10-15cm, and 10-15 side branches are retained on one side of the main branch, and water and fertilizer management is strengthened;

[0010] S4. In the spring of the third year, all secondary side branches are pruned back. The side branches should be pruned to a uniform length to keep the tree balanced.

[0011] S5. After the new buds sprout, the newly sprouted branches of the lateral branches are cultivated into lateral leading trunks. The length of the secondary lateral branches produced on the lateral branches should be controlled to promote flowering and fruiting;

[0012] S6. After the tree shape is initially established, strengthen water and fertilizer management, so that flower buds will form in the same year and a certain yield can be achieved in the fourth year after planting.

[0013] In some examples, the S5 further includes:

[0014] S51. After the tree is initially formed, regularly prune the overgrown branches, crossed branches, and overlapping branches inside the tree to maintain the transparency and layering inside the crown;

[0015] S52. Prune the top branches that grow too strong every year to encourage them to grow outwards and avoid the formation of a structure that affects light by forming an overly high crown.

[0016] S53. Bend the branches in the middle of the crown appropriately so that they face outward and droop, forming an inverted umbrella shape. When pruning, focus on pruning strong branches and keep weak branches as much as possible to balance the nutrient distribution of the tree.

[0017] In some examples, this also includes:

[0018] S7. Prune regularly in spring and autumn every year to remove dead branches, diseased branches, weak branches and crossed branches. For strong branches, bend or shorten them appropriately to promote the stability of the overall shape of the tree.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] In the above scheme, the 2D structure of the hedge is improved to an inverted umbrella-shaped three-dimensional structure, which makes the tree grow more evenly, increases the light-receiving area on both sides, improves photosynthesis, and accumulates more nutrients. It not only has good ventilation and light transmission capabilities, but also can effectively protect the root position under the tree, making the soil moisture more stable, reducing the damage to the roots caused by temperature and humidity fluctuations, making the tree stronger, and the fruit quality better. The increase in yield and quality greatly improves the economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] S2. Before budding in the spring of the second year, the two main branches were pulled and fixed with steel wires at a height of 2.2m, extending 1.5m to both sides, and the buds on the back were erased. The bud activation technology was applied to the buds on the back and both sides;

[0032] S3. Pull down and fix the newly grown side branches on the two main branches to both sides of the main branches, so that the angle between them and the ground is 75°, the spacing between the side branches is 10 cm, and 10 side branches are retained on one side of the main branch, and water and fertilizer management is strengthened;

[0033] S4. In the spring of the third year, all secondary side branches are pruned back. The side branches should be pruned to a uniform length to keep the tree balanced.

[0034] S5. After the new buds sprout, the newly sprouted branches of the lateral branches are cultivated into lateral leading trunks. The length of the secondary lateral branches produced on the lateral branches should be controlled to promote flowering and fruiting;

[0035] S51. After the tree is initially formed, regularly prune the overgrown branches, crossed branches, and overlapping branches inside the tree to maintain the transparency and layering inside the crown;

[0036] S52. Prune the top branches that grow too strong every year to encourage them to grow outwards and avoid the formation of a structure that affects light by forming an overly high crown.

[0037] S53. Bend the branches in the middle of the crown appropriately, so that they face outward and droop, forming an inverted umbrella shape. When pruning, focus on pruning strong branches and keep weak branches as much as possible to balance the nutrient distribution of the tree.
