Description

Technical Field

[0001] This invention belongs to the field of tree shaping and cultivation technology, and more specifically, it relates to a method for cultivating aerial tree shapes. Background Technology

[0002] In the field of landscaping, tree shaping is one of the core means to create distinctive landscapes and enhance their aesthetic value. There are many existing tree shaping forms, including three-dimensional, two-dimensional, interlocking, and combined intertwined forms, but they all follow the traditional design form of solid at the bottom and open at the top, resulting in severe homogenization of structural forms and a lack of innovative visual effects.

[0003] Meanwhile, the cultivation of large-scale garden trees takes too long. The cultivation period for woven vase-shaped trees in the south and structural tree chairs and pavilions in the north is generally more than 10 or 20 years, and some shapes even take as long as 30 or 40 years. The large amount of manpower and material resources invested in the cultivation process are seriously mismatched with the final landscape benefits, resulting in an imbalance between input and output. The excessive time cost makes it difficult to promote such shapes on a large scale.

[0004] While cliff-style bonsai displays offer a visually suspended effect, this technique relies on the pot and cliff face, making it impossible to cultivate large, suspended trees on flat ground. Furthermore, current tree-shaping techniques fail to integrate traditional craftsmanship with grafting onto living trees, resulting in insufficient cultural depth and a lack of adherence to traditional aesthetic principles. Therefore, there is an urgent need for a method to cultivate large, suspended trees on flat ground that features a short cultivation cycle, innovative styling concepts, and both artistic beauty and cultural significance, thereby addressing the numerous shortcomings of existing techniques. Summary of the Invention

[0005] The purpose of this application is to provide a method for cultivating aerial tree shapes, in order to solve the technical problems of existing technologies such as monotonous tree shapes, excessively long cultivation cycles, low input-output ratios, inability to cultivate large aerial tree shapes on flat ground, and insufficient cultural and aesthetic connotations.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A method for cultivating a suspended tree shape is provided, including the following steps: S1. Cut off the main trunk of the tree with multiple branches; graft the roots of the same tree species onto the lower end of the main trunk; S2. Construct a double-layered rooting facility adapted to the main trunk, plant the main trunk on the upper side of the double-layered rooting facility, and allow the tree roots to grow in the double-layered rooting facility and form the main shape root system; S3. After the new shoots of the branch trunk reach the preset thickness, multiple extension trunks of the same tree species are grafted in series at the end of the branch trunk to form a multi-layer structure around the main trunk. S4. Construct a secondary rooting facility below the center point of each of the extended stems, and perform rooting treatment below the center point of each of the extended stems, so that the extended stems take root in the secondary rooting facility and form a secondary shaped root system; S5. After the main root system has grown to the preset thickness and penetrated below the ground, the interlayer rooting facility under the main trunk is gradually removed according to the growth cycle. S6. After the secondary root system has grown to the preset thickness and penetrated below the ground, the secondary rooting facility is removed.

[0007] In one possible implementation, in step S5, while gradually removing the interlayer rooting facilities below the main trunk according to the growth cycle, shaped branches are grafted onto the branch trunks and the extension trunk, and the shaped branches are pruned and controlled.

[0008] In one possible implementation, step S2, the sandwich rooting facility adapted to the trunk includes: The inner lining is a brick conical structure, with the outer diameter of the inner lining gradually increasing from top to bottom; The first outer wall, a brick-built cylindrical structure, is located on the outer periphery of the inner lining; and The first filler is filled in the interlayer between the inner lining and the first outer wall; the first filler is a mixture of sand, organic fertilizer and stones, so that the main root system bends when it encounters stones, forming a variety of shapes.

[0009] In one possible implementation, the outer diameter of the liner is smaller than the outer diameter of the main trunk.

[0010] In one possible implementation, step S4, the secondary rooting facility constructed below the center point of each of the extended stems, includes: The second outer wall is a brick-built cylindrical structure, and its diameter is larger than the connection area between the branch trunk and the extension trunk; and The second filler is filled within the space enclosed by the second outer wall; the second filler is sand and gravel to promote the growth of the root system of the sub-shape.

[0011] In one possible implementation, the height of the second outer wall is greater than the height of the extension trunk, so that the second filler covers the rooting location of the extension trunk.

[0012] In one possible implementation, step S1, specifically the grafting of the same tree root at the lower end of the trunk, is performed as follows: First, the bark layer at the lower edge of the trunk is trimmed; then, roots of the same species with the required diameter are selected; finally, multiple roots are grafted along the circumference of the trunk at the lower end using the bark grafting method.

[0013] In one possible implementation, after the root grafting is completed, each root is fixed with nails, a tree healing agent is applied to the grafting interface, and a rooting agent is applied to the end face of the root.

[0014] In one possible implementation, step S2, specifically the routine maintenance of the main trunk, involves the following steps: Spray water on the main trunk daily to keep it moist, and promptly remove any new buds sprouting from the main trunk; pinch off the tips of any new buds on the branches that are close to the main trunk to maintain the growth dominance of the upper part of the branches.

[0015] In one possible implementation, step S3, specifically the grafting of the extension trunk of the same tree species to the end of the branch trunk, is as follows: Select branches of the same tree species with a diameter that is basically the same as that of the branch trunk as the extension trunk; First, remove the regenerated branches on the branch trunk, peel off the bark symmetrically on both sides at the end of the branch trunk to form double ear bark, and peel the bark on the extension trunk at the position relative to the double ear bark; Then, half mortises are made at the joint ends of the branch trunk and the extension trunk, and corresponding tenons are made of hardwood. Finally, insert the tenon into the mortise, and after the joint ends of the branch trunk and the extension trunk are aligned, fix the double ear skin to the peeled position on the extension trunk with nails, and wrap it with plastic wrap to keep it moist.

[0016] The method for cultivating a suspended tree shape provided in this application embodiment, compared with the prior art, can achieve a unique and stable suspended tree shape, combining ornamental and practical value. The lower end of the main trunk is grafted with roots of the same tree species, and a layered rooting system is used. The high compatibility of grafting with the same tree species ensures a high survival rate, and the main root system provides core support. Branches are grafted with extension trunks using a mortise and tenon double-ear grafting method, which can be connected multiple times to form a multi-layered structure, enhancing the plasticity of the shape. Each extension trunk is equipped with a secondary rooting system, forming a secondary root system that shares the weight of the main trunk and prevents branch breakage. Gradually removing the rooting system protects root development, reduces the cultivation failure rate, and ultimately forms a unique suspended shape with a hollow base and a solid top, integrating artistic appeal and structural stability.

[0023] Please refer to the following: Figures 1 to 3 The cultivation method for the aerial tree shape provided in this application is now described. The cultivation method for the aerial tree shape includes the following steps: S1. Select the tree to be cultivated, and cut off the main trunk 1 of the tree with multiple branches 2; graft the root 11 of the same tree species to the lower end of the main trunk 1.

[0024] S2. Construct a double-layered rooting facility 4 adapted to the main trunk 1, plant the main trunk 1 on the upper side of the double-layered rooting facility 4, and perform daily maintenance on the main trunk 1 so that the tree roots 11 grow in the double-layered rooting facility 4 and form the main shape root system 6.

[0025] S3. After the new shoots of the branch trunk 2 reach the preset thickness, the extension trunk 3 of the same tree species is grafted to the end of the branch trunk 2 using the tenon and mortise double ear grafting method, and multiple series grafting can be carried out to form a multi-layer structure around the main trunk 1.

[0026] S4. Construct a secondary rooting facility 5 below the center point of each of the extended trunks 3, and perform rooting treatment below the center point of each of the extended trunks 3, so that the extended trunks 3 take root in the secondary rooting facility 5 and form a secondary shaped root system 7.

[0027] S5. After the main shaped root system 6 grows to the preset thickness and penetrates below the ground, the interlayer rooting facility 4 below the main trunk 1 is gradually removed according to the growth cycle. During the removal process, the removal rhythm is adjusted according to the growth of the main shaped root system 6.

[0028] S6. After the secondary root system 7 has grown to the preset thickness and penetrated below the ground, the secondary rooting facility 5 is removed.

[0029] After the interlayer rooting facility 4 and the secondary rooting facility 5 are completely removed, a tree shape with a hollow bottom and a solid top is formed.

[0030] Prioritize tree species that are easy to root, such as banyan, willow, fast-growing poplar, mulberry, and black locust. With the help of rooting agents, they can be used with most landscaping tree species.

[0031] The main trunk 1 should preferably be about 50 cm in diameter, with no less than 3 branches 2 and the angle between the branches 2 and the main trunk 1 should be less than or equal to 120 degrees. The main trunk 1 should be 1 meter high, and the branches 2 should be 20 to 30 cm in diameter and 2.5 to 3.0 meters long. Only the branches should be cut off and the original main trunk should be retained, so as not to damage the natural environment.

[0032] The specifications of the main trunk 1 and branch trunk 2 can be adjusted according to the needs of the garden landscape to suit small, medium and large aerial sculpting; grafting tools such as electric saws and professional grafting knives can be used to improve operating efficiency; precast concrete parts can be used to replace bricks for rooting facilities to shorten the construction period; and it can be combined with an intelligent drip irrigation system to achieve automated root maintenance, moisturizing and fertilization.

[0033] The aerial tree shaping method provided in this application, compared with existing technologies, can achieve a unique and stable aerial tree shape, combining ornamental and practical value. The lower end of the main trunk 1 is grafted with roots 11 of the same tree species, along with a layered rooting device 4. The high compatibility of grafting with the same tree species ensures a high survival rate, and the main shaped root system 6 provides core support. The branch trunks 2 are grafted with extension trunks 3 using a mortise and tenon double-ear grafting method, which can be connected multiple times to form a multi-layered structure, enhancing the plasticity of the shape. Each extension trunk 3 is equipped with a secondary rooting device 5, forming a secondary shaped root system 7, which shares the weight of the main trunk 1 and prevents branch breakage. The gradual removal of the rooting devices protects root development, reduces the cultivation failure rate, and ultimately forms a unique aerial shape with a hollow bottom and a solid top, integrating artistic appeal and structural stability.

[0034] The factors that embody being in mid-air are: First, the difference in weight, thickness, and size between the lower root system and the main trunk, branches, and extension trunk of the tree creates a soaring momentum with the lower part being lighter and the upper part heavier.

[0035] Second, in addition to maintaining the apical dominance of the last extension trunk during the growth process, branches will also grow on the branching trunks and extension trunks. Based on the characteristics of the trunk, dragon-shaped branches can be grafted, and wind-blown branches and forest branches can be cultivated by pruning. The lower part is a fixed object, and the upper part is a tender shoot. When the wind blows, it creates a feeling of upward movement.

[0036] Further, please refer to Figures 1 to 3 As a specific implementation of the cultivation method for the aerial tree shape provided by the present invention, in step S5, while gradually removing the interlayer rooting facility 4 below the main trunk 1 according to the growth cycle, shaping branches 8 are grafted onto the branch trunk 2 and the extension trunk 3, and the shaping branches 8 are pruned and controlled.

[0037] For shaping branch 8, tree species without dragon-shaped trunks, such as willow, mulberry, Chinese locust, and banyan, can be used. Pruning and control should follow the principle of retaining the top and strictly controlling the remaining branches. Except for the last level extension trunk 3, which retains the growth advantage at the top, branches with a diameter of 5 cm or more on the other branches should be cut off from the base to promote the re-budding and formation of tender branches.

[0038] According to the needs of landscape design, the 8-shaped branches can be grafted in combination, such as combining dragon-shaped branches with forest branches; formulate a periodic pruning plan, lightly prune and shape the 8-shaped branches every quarter to maintain their airy posture; after pruning, apply tree healing agent to the cut to prevent bacterial infection.

[0039] By adopting the above technical solutions, the visual layers of the upper part of the tree are enriched by grafting the shaping branch 8, making the upper part present a light and floating posture, forming a strong visual contrast with the heavy central trunk, and enhancing the effect of being suspended in the air; pruning and control ensure that the tree's nutrients are concentrated in the shaping branch 8, maintaining the stability of the suspended shape; the curved shape of the shaping branch 8 fully reflects the traditional aesthetic principle that straight lines have no scenery and curves are beautiful, enhancing the artistic value of the shape.

[0040] Further, please refer to Figures 1 to 3 As a specific implementation of the cultivation method for the aerial tree shape provided by the present invention, in step S2, the sandwich rooting facility 4 adapted to the trunk 1 includes an inner lining 41, a first outer wall 42 and a first filler 43.

[0041] The inner lining 41 is a brick-built conical structure. The outer diameter of the inner lining 41 gradually increases from top to bottom, and the outer diameter of the top of the inner lining 41 is smaller than the outer diameter of the main trunk 1.

[0042] The first outer wall 42 is a brick-built cylindrical structure located on the outer periphery of the inner lining 41.

[0043] The first filler 43 is filled in the interlayer between the inner lining 41 and the first outer wall 42; the first filler 43 is a mixture of sand, organic fertilizer and stones, so that the main shaped root system 6 bends when it encounters stones, forming a state of varied shapes.

[0044] The inner lining 41 is a brick conical structure, 2 meters high, with a bottom diameter of about 2 meters. The top diameter is determined according to the specifications of the main trunk 1, and is thinner at the top and thicker at the bottom. It is not smoothed after being built.

[0045] The first outer wall 42 is a brick-built cylindrical structure located 50 to 100 centimeters from the outer perimeter of the inner lining 41, with a wall height of 3 meters and a thickness of 30 centimeters.

[0046] The first filler 43 is a mixture of sand, fermented organic fertilizer, stones and rubble, with stones and rubble accounting for about a quarter. It is filled to 20 to 30 centimeters below the top of the inner lining 41, guiding the main shape's root system 6 to bend around the stones and form a curved shape.

[0047] The proportion of the first filling material 43 can be adjusted according to the root growth characteristics of the cultivated tree species. For example, for tree species with fleshy roots, the proportion of stones can be reduced and the aeration of sandy soil can be increased. Drainage gaps can be reserved between the inner lining 41 and the first outer wall 42 to prevent water accumulation and root rot. A small amount of slow-release fertilizer can be mixed into the filling material to continuously provide nutrients for root growth.

[0048] By adopting the above technical solutions, the upper and lower coarse structure of the inner lining 41 provides guidance for the downward growth of the root system, and the first outer wall 42 ensures the overall stability of the facility; the composite ratio of the first filling material 43 simulates the structure of natural soil, which not only provides sufficient nutrients for the growth of the root system, but also shapes the main root system 6 with various shapes through stones and rubble, thus achieving a combination of aesthetics and growth; the sandwich structure creates an independent space for the growth of the root system, which is convenient for the control of the root system shape in the later stage.

[0049] Further, please refer to Figures 1 to 3 As a specific embodiment of the cultivation method for the aerial tree shape provided by the present invention, the outer diameter of the inner lining 41 is smaller than the outer diameter of the trunk 1.

[0050] The outer diameter of the top of the inner lining 41 is smaller than the outer diameter of the main trunk 1. Specifically, the diameter of the lower part of the main trunk 1 is 5 to 10 centimeters larger than the diameter of the top of the inner lining 41. The main trunk 1 is placed directly on the top of the inner lining 41, and the branches 2 are fixed with bamboo or wooden poles.

[0051] A non-slip rubber pad can be laid on the top of the inner liner 41 to increase the contact friction between the main stem 1 and the inner liner 41 and improve the planting stability; a fixing hole can be reserved at the top of the inner liner 41 to help fix the main stem 1 with ropes to prevent it from falling over.

[0052] By adopting the above technical solution, the stability of the main trunk 1 planted at the top of the inner lining 41 is ensured, and the main trunk 1 is prevented from falling over due to the shift of the center of gravity. The gap between the main trunk 1 and the inner lining 41 provides a channel for the roots to grow into the interlayer, promoting the even distribution of the main shape roots 6 in the interlayer. This lays the foundation for the roots to grow into a figure-eight support structure in the later stage, and enhances the overall support of the tree.

[0053] Further, please refer to Figures 1 to 3 As a specific embodiment of the cultivation method for the aerial tree shape provided by the present invention, in step S4, the secondary rooting facility 5 built below the center point of each of the extended trunks 3 includes a second outer wall 51 and a second filler 52.

[0054] The second outer wall 51 is a brick-built cylindrical structure, and the diameter of the second outer wall 51 is larger than the connection area between the branch trunk 2 and the extension trunk 3.

[0055] The second filler 52 is filled in the space enclosed by the second outer wall 51; the second filler 52 is sand and gravel soil to promote the growth of the sub-shaped root system 7.

[0056] The second outer wall 51 is a brick-built cylindrical structure with a diameter of 2 meters, which is larger than the connection area between the branch trunk 2 and the extension trunk 3, so as to avoid the grafting end being squeezed by the facility; the second filling material 52 is sandy soil with good air permeability and water permeability, which is filled in the space enclosed by the second outer wall 51 and completely covers the rooting position of the extension trunk 3.

[0057] Drainage holes can be opened at the bottom of the second outer wall 51 to prevent water accumulation from causing the roots of the extension trunk 3 to rot; the diameter of the second outer wall 51 can be adjusted according to the thickness of the extension trunk 3, and the diameter of the thicker trunk can be appropriately increased to leave enough space for the growth of the secondary root system 7; a small amount of humus can be mixed into the sandy soil to increase the nutrient content of the second filler 52 and promote the rapid growth of the secondary root system.

[0058] By adopting the above technical solution, the second outer wall 51 creates an independent and closed environment for the extension trunk 3 to grow roots and form a secondary root system 7, avoiding external factors from interfering with the rooting process; the air permeability and water permeability of the sandy soil are suitable for the environmental needs of tree rooting, effectively improving the rooting survival rate of the extension trunk 3; the diameter of the second outer wall 51 is larger than the connection area, protecting the grafting end from compression and ensuring the healing effect of the tenon and mortise double ear grafting joint.

[0059] Further, please refer to Figures 1 to 3 As a specific embodiment of the cultivation method for the aerial tree shape provided by the present invention, the height of the second outer wall 51 is greater than the height of the extension trunk 3, so that the second filler 52 wraps the rooting position of the extension trunk 3.

[0060] The second outer wall 51 is built at a height higher than the extension trunk 3, specifically about 20 cm higher than the extension trunk 3, so that the second filler 52 completely covers the rooting position of the extension trunk 3 and maintains the humidity of the rooting environment.

[0061] Adjust the height of the second outer wall 51 according to the rooting position of the extended trunk 3. When the rooting position is high, increase the height of the second outer wall 51 appropriately. A retaining edge can be made at the top of the second outer wall 51 to prevent rainwater from washing away the second filler 52. Geotextile can be laid on the inside of the second outer wall 51 to prevent the filler from being lost from the brick joints.

[0062] By adopting the above technical solution, the rooting position of the extension trunk 3 can be completely wrapped, ensuring the humidity of the rooting environment is stable and providing continuous moisture conditions for the growth of the secondary shape root system 7; preventing external factors such as rain and wind from eroding the rooting position and improving the growth quality of the secondary shape root system 7; the height advantage of the second outer wall 51 allows the second filler 52 to form a slight fixing effect on the extension trunk 3, helping to maintain the horizontal posture of the extension trunk 3, which is conducive to the formation of a multi-layered surrounding structure.

[0063] Further, please refer to Figures 1 to 3 As a specific embodiment of the cultivation method for the aerial tree shape provided by the present invention, the specific operation of grafting the root 11 of the same tree species to the lower end of the trunk 1 in step S1 is as follows: First, the bark layer at the lower edge of the trunk 1 is trimmed; then, the same type of tree root 11 with a diameter that meets the requirements is selected; finally, multiple tree roots 11 are grafted along the circumference of the trunk 1 at the lower end of the trunk 1 using the bark grafting method.

[0064] Before grafting, use a sharp knife to smooth the bark layer at the lower edge of the main trunk 1 to ensure a flat grafting surface; select a healthy root 11 of the same tree species with a diameter of 0.5 to 1 cm and a length of 20 to 30 cm as a scion; graft no less than two roots 11 around the main trunk 1 using the bark grafting method, with the scions spaced 5 to 10 cm apart, so that a uniform ring of grafted roots is formed at the lower end of the main trunk 1.

[0065] Before grafting, disinfect the grafting surface of the main trunk 1 and the scion root 11 with alcohol to prevent bacterial infection; adjust the number of grafted roots 11 according to the diameter of the main trunk 1, the larger the diameter of the main trunk 1, the more grafts are needed; during grafting, rooting agent can be applied to the grafting surface to improve the healing and survival rate of the grafted roots.

[0066] By adopting the above technical solution, the bark grafting method is simple to operate, has a high healing survival rate, and is suitable for the grafting needs of the main trunk 1 of a living tree; the root 11 is evenly grafted around the circumference of the main trunk 1, which can form a ring of main roots at the lower end of the main trunk 1, ensuring the support and balance of the tree; the selection of thin and strong root 11 as scion reduces the damage to the rootstock main trunk 1, and at the same time facilitates rapid healing and rooting.

[0067] Further, please refer to Figures 1 to 3 As a specific embodiment of the cultivation method for the aerial tree shape provided by the present invention, after the grafting of the tree roots 11 is completed, each tree root 11 is fixed with a nail, a tree healing agent is applied to the grafting interface, and a rooting agent is applied to the end face of the tree root 11.

[0068] After grafting, use nails to fix each grafted root to the bark of the main stem to prevent the scion from falling off; apply tree-specific healing agent evenly to the grafting interface to completely seal the grafting interface; apply naphthaleneacetic acid-based rooting agent to the end face of the grafted root to promote full rooting of the end face of the main stem.

[0069] After fixing with nails, wrap the graft union with waterproof tape to enhance the fixing effect and improve the sealing. A small amount of bactericide can be mixed into the healing agent to further prevent the graft union from rotting. The rooting agent should be applied by diluting it with water to avoid burning the roots with too high a concentration.

[0070] By adopting the above technical solutions, the nail fixing ensures the stability of the connection between the grafted root and the main trunk 1, prevents the scion from falling off before rooting, and improves the grafting survival rate; the tree healing agent seals the grafting interface, isolates air, pathogens and moisture, prevents the grafting interface from rotting, and promotes the formation of healing tissue; the rooting agent promotes the full rooting of the end face of the main trunk 1 and the grafted root, quickly forms the main shape root system 6, and shortens the root cultivation cycle.

[0071] Further, please refer to Figures 1 to 3 As a specific implementation of the cultivation method for the aerial tree shape provided by the present invention, the specific operation of daily maintenance of the main trunk 1 in step S2 is as follows: Spray water on the main trunk 1 daily to keep it moist, and remove any new buds that sprout from the main trunk 1 in a timely manner; pinch off the tips of any new buds on the branch trunk 2 that are close to the main trunk 1 to maintain the growth advantage of the upper part of the branch trunk 2.

[0072] Spray water on the main trunk 1 stump about 3 times a day to keep the bark moist; remove any new buds that sprout from the main trunk 1 as soon as they are discovered to avoid wasting nutrients; pinch off the tops of new buds on the branch 2 that are close to the main trunk 1 when they grow to 20 to 30 centimeters to preserve the growth advantage of the upper part of the branch 2.

[0073] During hot and dry seasons, increase the frequency of watering and wrap the tree stump with moisturizing cotton to enhance the moisturizing effect; after removing the new buds of the main trunk 1, lightly prune the bud openings to prevent the new buds from sprouting again; the topping operation can be replaced by shortening the branch trunk 2 according to its growth condition, and the growth height of the branch trunk 2 can be flexibly controlled.

[0074] By adopting the above technical solutions, continuous water spraying ensures the water supply of the tree stump before rooting, prevents the bark from drying and cracking, and greatly improves the survival rate of planting; removing new buds of the main trunk 1 prevents nutrients from being concentrated in the ineffective growth of the main trunk 1, and ensures that all nutrients are transported to the branch trunk 2 and the grafting root; the topping operation maintains the growth advantage of the upper part of the branch trunk 2, so that the branch trunk 2 thickens rapidly, laying the foundation for nutrient transport for the subsequent grafting extension trunk 3.

[0075] Further, please refer to Figures 1 to 3 As a specific implementation of the cultivation method for the aerial tree shape provided by the present invention, in step S3, the specific operation of grafting the extension trunk 3 of the same tree species onto the end of the branch trunk 2 using the mortise and tenon double-ear grafting method is as follows: Select a branch of the same tree species with a diameter that is basically the same as that of the branch trunk 2 as the extension trunk 3.

[0076] First, remove the regenerated branches on the branch trunk 2, peel off the bark symmetrically on both sides at the end of the branch trunk 2 to form double ear bark 91, and peel the bark on the extension trunk 3 at the position relative to the double ear bark 91.

[0077] Then, half mortises are made at the joint ends of the branch trunk 2 and the extension trunk 3, and corresponding tenons 92 are made of hardwood.

[0078] Finally, insert the tenon 92 into the mortise. After the joint ends of the branch trunk 2 and the extension trunk 3 are aligned, fix the double ear skin 91 to the peeled position on the extension trunk 3 with nails and wrap it with plastic wrap to keep it moist.

[0079] Select a robust branch of the same species as branch 2, with an upward curve at the small end and a length of 2 to 3 meters, as the extension trunk 3. Remove the regenerated branches on branch 2, saw out a fresh joint surface, peel off the bark symmetrically on both sides, 10 cm wide and 20 cm long, to form double ear bark 91, and remove the same area of ​​bark at the corresponding position on the extension trunk 3.

[0080] Half mortises are made at the joints of branch trunk 2 and extension trunk 3, with a small end width of 5 cm, a large end width of 10 cm, and a length of 8 cm. Tenons 92, made of hardwood, are made to match the half mortises, with a length of 16 cm, a waist width of 5 cm, and a width of 10 cm at both ends. Tenons 92 are wedged into the half mortises to make the joints flush. After the double-ear skin 91 is aligned with the peeled position of extension trunk 3, it is fixed with nails. Finally, the joint area is wrapped tightly with plastic wrap and tape to keep it moist.

[0081] After the hardwood tenon is made, it is treated with anti-corrosion to prevent it from rotting before the tree heals; when wrapping and moisturizing, a three-layer structure of moisturizing cotton, plastic wrap and waterproof tape is used to improve the moisturizing effect; after the tenon and mortise are joined, a tree healing agent can be applied to the joint to promote rapid healing of the bark.

[0082] By adopting the above technical solutions, the double-ear bark 91 structure increases the contact area between the bark of the branch trunk 2 and the extension trunk 3, which greatly improves the grafting survival rate; the mortise and tenon structure realizes the mechanical fixation of the grafting of living trees, ensuring that the docking end is stable and does not loosen, and solves the problems of easy falling and slow healing in traditional grafting; the small head of the extension trunk 3 bends upward, laying the foundation for the upward soaring posture of the later aerial shape.

[0083] Specific implementation method 1: Cultivating a suspended tree shape using banyan trees This implementation method uses banyan trees as the cultivation species. Banyan trees are easy to root and are evergreen. They do not have natural dragon-shaped branches, so they are suitable for the combination of wind-blown branches and forest branches to create a light and floating effect. The overall cultivation cycle is 7 years.

[0084] S1: Cut off the main trunk 1 and graft root 11 Select a healthy banyan tree growing in nature, and cut only the fork of the tree to cultivate the main trunk 1. The main trunk 1 is 50 cm in diameter and has 4 branch trunks 2. The main trunk 1 is 1 meter high and the branch trunks 2 are 25 cm in diameter and 2.8 meters long. The original main trunk is retained without digging up the roots, so that it can continue to grow.

[0085] Grafting should be carried out when the banyan tree shoots sprout new buds in spring: use a sharp knife to smooth the bark layer at the lower edge of the main trunk 1, select 114 healthy banyan tree roots with a diameter of 0.8 cm and a length of 25 cm, and graft them along the circumference of the main trunk 1 at 8 cm intervals using the bark grafting method; after grafting, fix each graft with a decorative nail, apply tree healing agent to seal the graft union, and apply diluted naphthaleneacetic acid rooting agent to the remaining ends of the main trunk 1 and the ends of the grafted roots.

Ensure that the diameter of the main trunk 1 is larger than the top diameter of the inner lining 41 around its perimeter. Do not smooth the surface after construction. The first outer wall 42 is a brick cylinder, located 80 centimeters from the outer perimeter of the inner lining 41. The wall is 3 meters high and 30 centimeters thick. Fill the sandwich between the inner lining 41 and the first outer wall 42 with the first filler material 43. The ratio of sand, organic fertilizer and pebbles in the first filler material 43 is 3:2:1. Fill the material up to 25 centimeters below the top of the inner lining 41.

[0087] Place the grafted banyan tree trunk 1 at the top of the inner lining 41, and use bamboo poles to help fix the branches 2. Fill the facility with sterilized sand up to 50 cm above the trunk 1 and water it thoroughly. After the soil settles, add more soil and water it in time.

[0088] Daily maintenance: Spray water on the main trunk 1 every morning, noon and evening to keep it moist. Remove any new buds that sprout on the main trunk 1 immediately. When the new buds of the branch trunk 2 near the main trunk 1 grow to 25 cm, pinch off the top. Continue to maintain for 1.5 years. A ring of main shape root system 6 will form at the lower end of the main trunk 1, and the new branches of the branch trunk 2 will reach a thickness of 3 to 5 cm.

[0089] S3: Mortise and tenon double-ear grafting extension trunk 3 Select a robust banyan branch with a diameter approximately the same as that of branch 2, an upward curve at the small end, and a length of 2.5 meters as the extension trunk 3; remove the regenerated branches on branch 2, saw out a fresh joint surface, peel off the bark symmetrically on both sides with a width of 10 cm and a length of 20 cm to form double ear bark 91, and remove the same area of ​​bark at the corresponding position on extension trunk 3; make a half mortise at the joint end (5 cm at the small end, 10 cm at the large end, and 8 cm in length), and make a tenon 92 out of hardwood (16 cm in length, 5 cm at the waist of tenon 92, and 10 cm at both ends), wed the tenon 92 into the half mortise to make the joint end flush, align the double ear bark 91 with the peeled position of extension trunk 3, fix it with nails, and wrap it tightly with plastic wrap and tape to keep it moist.

[0090] The extension trunk 3, which was grafted for the first time, was grafted a second time in series to form a two-layer extension trunk 3 structure, which forms a double-layer ring layout around the main trunk 1.

[0092] After one year of continuous maintenance, roots will sprout from the cut site on the trunk, forming a secondary root system within the secondary rooting facility.

[0093] S5: Gradually remove the interlayer rooting facilities 4 and graft shaped branches 8 In the fourth year after planting, the root system of the main structure was inspected: there were 6 main roots on the main stem, with a root diameter of 10 cm, and the roots were deep below the ground, meeting the criteria for removal.

[0094] Starting from the bottom of the inner lining 41 and the first outer wall 42, bricks are removed year by year. During the removal process, the root support is checked in real time. If the tree body becomes loose, the removal is temporarily suspended. At the same time, wind-blown branches are made on the branch trunk 2 and the extension trunk 3. Jungle branches are cultivated from the base of the trunk as shaping branches 8. The shaping branches 8 are pruned and controlled. Except for the top of the last level extension trunk 3, branches with a diameter greater than 5 cm on the other branches are cut off from the base.

[0095] S6: Remove secondary rooting facilities 5 In the 5.5 years after planting, the diameter of the secondary root system 7 reaches 12 cm and extends deep into the ground, providing stable support for the extension trunk 3. The second outer wall 51 of all secondary rooting facilities 5 is removed, and the double-layered root system 7 forms a surrounding support structure.

[0096] S7: Creates a tree-like shape suspended in mid-air. Seven years after planting, the interlayer rooting facility 4 was completely removed, and the banyan tree formed a complete aerial shape: the main shaped root system 6 is distributed in a figure-eight shape, the double-layered shaped root system 7 surrounds the main trunk 1 to form a stable support, and a hollow space with a diameter of 2 meters is formed below the main trunk 1; the upper wind-blown branches and forest branches sway lightly, forming a strong visual contrast with the heavy central trunk, and the whole presents an aerial posture of a drone flying, which can be used as a unique garden photo spot.

[0097] Specific Implementation Method 2: Cultivating aerial tree shapes using willow trees This implementation method uses willow as the cultivation species.
