Description

Technical Field

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

[0002] With the development of the landscape architecture industry, plant shaping techniques are constantly innovating, and various tree shapes such as tree hedges, tree gates, tree benches, tree bridges, and tree pavilions are emerging, enriching the expressive forms of landscape architecture. However, most existing tree shapes are small or medium-sized structures, with heights generally within the range of ten meters, belonging to niche landscape applications. The technology for shaping ultra-large trees is still in its infancy.

[0003] Tower structures are a classic tall landscape design. Most existing well-known tower structures are made of inanimate civil engineering or steel structures. However, there is currently no mature cultivation technology for tree towers created using living trees. Existing tree-shaping techniques face several technical challenges when cultivating ultra-large tower structures: First, structural stability is difficult to guarantee. Tall living tree towers need to withstand natural loads such as wind loads over a long period of time. Existing shaping techniques cannot effectively combine the stable design of structural mechanics with the growth characteristics of trees, making it difficult to achieve safe cultivation and long-term stability of tree towers tens of meters high.

[0004] Secondly, the combination of multiple trees is difficult to form. Super-large tree towers require the combination and cultivation of multiple trees. Existing technologies mostly use the grafting method to connect trees, which not only has the problems of strong trees eating weak trees and uneven growth, but also cannot achieve a unified connection of three or more trees. This easily leads to problems such as loose shape and local necrosis, resulting in a very low yield rate, and it cannot be adapted to the combination and cultivation of different tree species.

[0005] Third, the cultivation process affects the normal growth of trees. The cultivation of tall trees requires the construction of an operation platform. Current technology often uses external scaffolding, which severely blocks the trees from sunlight, directly affecting their normal growth and even causing them to weaken or die, resulting in the failure of the cultivation process. Fourth, existing styling techniques violate the growth characteristics of trees. In some attempts to styling extra-large trees, the excessive use of long-distance horizontal branches seriously violates the natural tendency of trees to grow upwards. At the same time, the use of branching styling methods can easily lead to problems such as imbalance in nutrient regulation and the death of local branches, making it impossible to achieve long-term stable growth of the tree tower.

[0006] In summary, there is currently no mature technology for cultivating ultra-large living tree towers, which makes it impossible to achieve standardized and high-success-rate cultivation of tall tree towers, thus restricting the large-scale development of the arboretum industry and the construction of arboretum parks. Summary of the Invention

[0007] The purpose of this application is to solve the above-mentioned problems in the prior art and provide a method for cultivating tree towers that can achieve standardized cultivation of ultra-large living tree towers, effectively improve the long-term stability and cultivation success rate of tree tower structures, and at the same time take into account the natural growth characteristics of trees to ensure the healthy growth of trees during the cultivation process.

[0008] To achieve the above objectives, the technical solution adopted in this application is as follows: A method for cultivating tree towers is provided, comprising the following steps: S1. Based on the growth characteristics and structural stability of trees, design the overall shape of the tree tower, determine the layered shrinking tower structure with a larger bottom and a smaller top, and plan the planting points of seedlings, the growth path of branches and trunks, and the layered connection nodes. S2. Construct a built-in hollow operating frame at the center of the tree tower cultivation location, and create a shape mold that matches the design of the tree tower based on the planned branch growth path and layered connection nodes. S3. Plant tree seedlings in groups at the preset planting points, and provide water and fertilizer after planting to promote rooting, survival and healthy growth of the seedlings. S4. After the seedlings reach the shaping and cultivation standards, the main trunk of the seedlings is directionally bent and fixed along the growth path preset by the shaping mold. In a progressive ring-forming method, the main trunks of multiple seedlings are connected in a closed loop at each layer connection node to form a stable tower-shaped skeleton structure layer by layer. S5. During the cultivation of the tree tower, the seedlings are continuously maintained and managed. After the main trunk of the tree tower has grown to a certain shape and the structure is stable, the shaping mold and the hollow operation frame are gradually removed to complete the live cultivation of the tree tower.

[0009] In one possible implementation, in step S1, the overall shape of the tree tower is designed to incorporate a triangular stabilizing structure, a hollow ventilation structure, and a circular closed-loop structure to improve the overall wind resistance and structural stability of the tree tower.

[0010] In one possible implementation, in step S2, the hollow operating frame is a vertically arranged hollow columnar structure fixed at the center of the tree tower. The hollow operating frame is equipped with a climbing ladder, and the outer side of the hollow operating frame is fixed to the ground by an oblique support, serving as both an operating platform and a central stable support.

[0011] In one possible implementation, step S2, which involves creating a mold that matches the tree tower design, includes: A basic vertical mold, set on the outside of the hollow operating frame, is used to guide the vertical growth of the seedling base and the initial closed-loop connection. The basic vertical mold is made of three iron wires, with the upper ends of the three wires connected in a progressively looping manner. The lower ends of the three wires are all attached to the wooden pole, and the upper ends of the three wires are flush with the upper end of the wooden pole. The segmented mold is set on the outside of the hollow operation frame and on the upper side of the basic vertical mold. It is set in segments along the vertical direction, corresponding to the growth path and connection node of each layer of the tree tower. The segmented mold is also equipped with a path guide structure and point markings that match the main trunk of the seedling.

[0012] In one possible implementation, the segmented mold adopts a double-layer structure design, including: The outer tower body is located outside the hollow operating frame and above the vertical mold of the foundation; the diameter of the outer tower body gradually decreases upwards; and The inner lining is located between the outer tower body and the hollow operating frame, and is divided into five sections from bottom to top; each section of the inner lining adopts a conical structure, and the section of the inner lining at the bottom is defined as the first section; The first inner lining section has its large-diameter end located on the lower side and connected to the outer tower body; the second inner lining section has its small-diameter end located on the lower side and connected to the small-diameter end of the first inner lining section, and its large-diameter end is connected to the outer tower body; the third inner lining section has its large-diameter end located on the lower side and connected to the large-diameter end of the second inner lining section; the fourth inner lining section has its small-diameter end located on the lower side and connected to the small-diameter end of the third inner lining section, and its large-diameter end is connected to the outer tower body; the fifth inner lining section has its large-diameter end connected to the top of the outer tower body, and its small-diameter end is located on the upper side of the outer tower body.

[0013] In one possible implementation, a support ring is provided at the connection between the large-diameter end of each inner lining segment and the outer tower body, and each support ring is fixedly connected to the hollow operating frame; the support ring is marked with the connection positioning point of the corresponding seedling trunk.

[0014] In one possible implementation, multiple triangular ribs are provided between the support ring and the hollow operating frame to improve the stability of the support ring.

[0015] In one possible implementation, step S3, specifically the operation of planting tree seedlings in groups at preset planting points, is as follows: The number of seedlings planted is 30, divided into 10 groups of 3. The 10 groups of seedlings are planted in a circular pattern with equal intervals. The 3 seedlings in each group are planted in an equilateral triangle, with one seedling facing the center of the circle and the other two on the edge of the circle.

[0016] In one possible implementation, step S4 specifically involves the following operations: By bending the main trunks of two or more saplings in the same plane in sequence along the same direction, the front end of the main trunk of the next sapling passes through the bend of the main trunk of the previous sapling and bends upward, and so on, a closed loop structure is formed, so that the main trunks of multiple independent saplings are connected to form a stable integrated structure.

[0017] In one possible implementation, in step S4, the main trunk of the seedling is connected in a closed loop using the progressive circular method at the base of the tree tower, each layer connection node, and the top closing position; for non-closed loop branch intersection nodes, they are fixedly connected by hooking or intertwining.

[0018] The tree tower cultivation method provided in this application has the following advantages compared with the prior art: 1. Solved the structural stability problem of super-large tree towers: The shrinking structure with a larger bottom and a smaller top, the triangular stable structure, the inner and outer double-layer structure, and the hollow ventilation structure are deeply integrated with the growth characteristics of trees. At the same time, the central built-in operating frame provides central stability support, ensuring the structural stability and resistance to natural disasters of tree towers tens of meters high from multiple dimensions, and realizing the safe cultivation of super-large living tree towers.

[0019] 2. The innovative progressive ring connection method breaks through the technical bottleneck of multi-tree combination shaping: Through this connection method, the main trunks of two or more trees can be connected in an integrated closed loop. This not only solves the problem of looseness at the beginning, middle and top of the multi-tree shaping, making multiple independent seedlings form a stable overall structure, but also avoids the problems of strong trees eating weak trees and uneven growth caused by traditional grafting methods. This greatly improves the success rate of shaping and can be adapted to the combination cultivation of different tree species, expanding the scope of application of the technology.

[0020] 3. The built-in hollow operating frame design takes into account both the needs of cultivation operations and tree growth: The hollow operating frame is set in the center of the tree tower, replacing the traditional external scaffolding. This completely avoids the operation facilities blocking the light of the trees, ensuring the normal growth of the trees during the cultivation process. At the same time, the hollow operating frame can also serve as a support structure for the shaping mold and a central stabilizing structure for the tree tower, achieving multiple uses and simplifying the construction of cultivation facilities.

[0021] 4. Fully aligning with tree growth characteristics to ensure long-term robust growth of the tree tower: The single-trunk, single-sapling shaping method avoids the problem of nutrient imbalance in branching shaping; the length of horizontal branches is strictly controlled in the shaping design, prioritizing near-vertical growth paths, and keeping the bending angle of branches within the range suitable for tree growth, fully conforming to the tree's natural upward growth tendency, and ensuring the long-term stability and robustness of the tree tower; at the same time, the accompanying root-nourishing and seedling-strengthening, phased shaping, and dormant growth rest programs further improve the survival rate of seedlings and the success rate of shaping.

[0022] 5. It fills the technological gap in ultra-large tree tower-shaped designs and provides core support for the development of the tree landscape industry: it realizes the standardized cultivation of living tree towers, and the height and specifications of the tree towers can be flexibly adjusted by replicating layered structural units to adapt to different landscape application scenarios; as the core landmark landscape of tree parks, the tree tower improves the product system of tree styling, lays a solid technical foundation for the large-scale construction of tree parks, and promotes the innovative development of the tree landscape industry.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] Please refer to the following: Figures 1 to 10 The method for cultivating the tree tower provided in this application is now described. The method for cultivating the tree tower includes the following steps: S1. Based on the growth characteristics and structural stability of trees, design the overall shape of the tree tower, determine the layered shrinking tower structure with a larger bottom and a smaller top, and plan the planting points of seedlings, the growth path of branches and trunks, and the layered connection nodes.

[0031] Tall trees such as elm, Chinese scholar tree, and mulberry are selected as cultivation targets. Combining their upward growth and branch flexibility, and adhering to the principle of structural mechanical stability, a layered, tapering tower shape (mainly circular) with a larger bottom and smaller top is designed. The plan includes 4 equidistant planting points at the bottom of the tree tower, a branch inclined growth path (angle controlled between 50° and 70°), and multi-level layered connection nodes. At the same time, long-distance horizontal branch design is avoided to conform to the natural growth characteristics of trees.

[0032] S2. Construct an internal hollow operating frame 1 at the center of the tree tower cultivation location. Based on the planned branch growth path and layered connection nodes, create a shape mold that matches the tree tower design. Fix the shape mold to the hollow operating frame 1 as a whole. Lay wire 22 to match the growth path of the branches.

[0033] S3. Plant tree seedlings in groups of 4 at the preset planting points. After planting, water thoroughly and carry out root care for at least one growth cycle. Only perform routine water and fertilizer and pest and disease control, without shaping operations, to promote the healthy root system of the seedlings and the main trunk to reach the preset thickness and height.

[0034] S4. After the seedlings reach the shaping and cultivation standards, the main trunk of the seedlings is directionally bent and fixed along the growth path preset by the shaping mold. Using a progressive ring-forming method, the main trunks of multiple seedlings are connected in a closed loop at each layer connection node to form a stable tower-shaped skeleton structure layer by layer.

[0035] After the seedlings reach the required standard, during the budding stage, the trunk is cut back to retain strong branches. The main trunk is then bent in a directional manner along the mold path and tied and fixed (this is done at noon or in the afternoon when the branches are more flexible). At each layer connection node, multiple main trunks are connected in a closed loop using a progressive circular method, building a tower-shaped framework layer by layer. The shaping is stopped during the hot summer period, allowing the seedlings to grow naturally and accumulate nutrients.

[0036] S5. During the cultivation of tree tower shapes, the seedlings are continuously maintained and managed. After the main trunk of the tree tower has grown to a certain shape and the structure is stable, the shaping mold and the hollow operation frame 1 are gradually removed to complete the live cultivation of the tree tower.

[0037] During the shaping and cultivation process, continuous water and fertilizer maintenance, bud removal, and branch reinforcement are carried out. After the main trunk of the tree tower has grown, integrated, and stabilized, the lower shaping mold is removed first. After the tree trunk wraps around the steel bars, the hollow operation frame 1 is removed in sections, and the cultivation of the living tree tower is finally completed.

[0038] Suitable for both North and South China: In the South, tall trees such as camphor, sycamore, and goldenrain tree are selected, and the bending angle of the branches is adjusted to 60-70° (to suit the high temperature and humidity growth environment in the South). The operating frame is treated with anti-corrosion (brushed with anti-rust paint), and the mold is made of corrosion-resistant stainless steel wire.

[0039] Small tree towers: Small tree towers (within 10 meters in height) suitable for courtyard landscaping. The simplified layered shrinkage structure is divided into 3 sections. The number of seedlings planted is adjusted to 12 in 4 groups. The operating frame is made of lightweight aluminum alloy. The mold is made of 22mm thin iron wire, shortening the cultivation cycle to 3-5 years.

[0040] Polygonal Tower Type: The overall shape of the tree tower is designed as a regular hexagon. Planting points 4 are set at equal intervals around the circumference of the regular hexagon. The layered connecting nodes are adjusted to adapt to the hexagonal structure. The progressive closed-loop shape is changed to a regular hexagon. The rest of the cultivation steps remain unchanged.

[0041] The tree tower cultivation method provided in this application has the following advantages compared with the prior art: 1. Solved the structural stability problem of super-large tree towers: The shrinking structure with a larger bottom and a smaller top, the triangular stable structure, the inner and outer double-layer structure, and the hollow ventilation structure are deeply integrated with the growth characteristics of trees. At the same time, the central built-in operating frame provides central stability support, ensuring the structural stability and resistance to natural disasters of tree towers tens of meters high from multiple dimensions, and realizing the safe cultivation of super-large living tree towers.

[0042] 2. The innovative progressive ring connection method breaks through the technical bottleneck of multi-tree combination shaping: Through this connection method, the main trunks of two or more trees can be connected in an integrated closed loop. This not only solves the problem of looseness at the beginning, middle and top of the multi-tree shaping, making multiple independent seedlings form a stable overall structure, but also avoids the problems of strong trees eating weak trees and uneven growth caused by traditional grafting methods. This greatly improves the success rate of shaping and can be adapted to the combination cultivation of different tree species, expanding the scope of application of the technology.

[0043] 3. The built-in hollow operating frame 1 design takes into account both the needs of cultivation operation and tree growth: The hollow operating frame 1 is set in the center of the tree tower, replacing the traditional external scaffolding, completely avoiding the obstruction of light to the trees by the operating facilities, ensuring the normal growth of the trees during the cultivation process. At the same time, the hollow operating frame 1 can also serve as a supporting structure for the shaping mold and a central stabilizing structure for the tree tower, realizing multiple uses and simplifying the construction of cultivation facilities.

[0044] 4. Fully aligning with tree growth characteristics to ensure long-term robust growth of the tree tower: The single-trunk, single-sapling shaping method avoids the problem of nutrient imbalance in branching shaping; the length of horizontal branches is strictly controlled in the shaping design, prioritizing near-vertical growth paths, and keeping the bending angle of branches within the range suitable for tree growth, fully conforming to the tree's natural upward growth tendency, and ensuring the long-term stability and robustness of the tree tower; at the same time, the accompanying root-nourishing and seedling-strengthening, phased shaping, and dormant growth rest programs further improve the survival rate of seedlings and the success rate of shaping.

[0045] 5. It fills the technological gap in ultra-large tree tower-shaped designs and provides core support for the development of the tree landscape industry: it realizes the standardized cultivation of living tree towers, and the height and specifications of the tree towers can be flexibly adjusted by replicating layered structural units to adapt to different landscape application scenarios; as the core landmark landscape of tree parks, the tree tower improves the product system of tree styling, lays a solid technical foundation for the large-scale construction of tree parks, and promotes the innovative development of the tree landscape industry.

[0046] Further, please refer to Figures 1 to 10 As a specific implementation of the tree tower cultivation method provided by the present invention, in step S1, the overall shape of the tree tower is designed to incorporate a triangular stable structure, a hollow ventilation structure and a circular closed-loop structure to improve the overall wind resistance and structural stability of the tree tower.

[0047] During the overall design phase of the S1 tree tower, three types of stable structures were integrated into the entire design and construction process: Triangular stable structure: Three seedlings in each group are planted in an equilateral triangle. The main trunks of the seedlings at the layered connection nodes are combined to form a triangular support. Triangular ribs 14 are welded between the support ring 13 and the operating frame to improve the local and overall structural strength by utilizing the mechanical stability of the triangle.

[0048] Hollowed-out ventilation structure: Ventilation gaps are reserved in the design of the tower-shaped frame. Both the mold and the operating frame adopt a hollowed-out design, allowing wind to pass through the gaps, reducing the windward surface of the tree tower and reducing the impact of wind load on the tree tower.

[0049] Circular closed-loop structure: The tree tower has a circular outline. The four seedling planting points are set at equal intervals along the circumference. The connecting nodes of each layer adopt a progressive circular method to form a circular closed loop, so that the tower body is evenly stressed and avoids local stress concentration.

[0050] A rhombus-shaped structural stability design can be incorporated into the triangular stable structure. At the intersection of branches in a non-closed loop, the four main trunks are combined into a rhombus, and then connected in the top, bottom, left, and right to form a circular closed loop, further offsetting the instability of the quadrilateral.

[0051] By adopting the above technical solutions, the wind resistance and stability issues of ultra-large tree towers can be addressed from the source of the design, deeply integrating structural mechanics principles with the cultivation of living tree towers, thus enhancing the tree towers' ability to withstand natural disasters (strong winds, heavy rain). The hollow ventilation structure effectively reduces the windward surface, preventing the tree tower from breaking branches or tilting due to excessive wind load, while ensuring ventilation and lighting for the seedlings inside the tower, promoting uniform growth. The circular closed-loop structure ensures uniform stress distribution throughout the tower, combined with triangular local supports, forming a stable system with uniform overall stress and localized reinforced support, significantly improving the long-term structural stability of the tree tower.

[0052] Further, please refer to Figures 1 to 10 As a specific embodiment of the tree tower cultivation method provided by the present invention, in step S2, the hollow operation frame 1 is a vertically arranged hollow column structure, fixed at the center of the tree tower. A climbing ladder 12 is provided on the hollow operation frame 1, and the outer side of the hollow operation frame 1 is fixed to the ground by an inclined support member 11, which serves as both an operation platform and a central stable support.

[0053] Operating frame construction: 16mm steel bars are used as uprights (4 main ones) and 12mm steel bars are used as ring connectors, which are welded into a vertical hollow column structure. The ring connectors are arranged at 1-meter intervals. 14mm horizontal steel bars are welded every 30cm along the height direction on the inner side of the uprights to make climbing ladders 12.

[0054] Fixing method: The operating frame is vertically fixed at the center of the tree tower cultivation. Ten 16mm steel bars (3-4m long) are arranged at equal intervals as diagonal support members 11. One end is inserted into the ground 1m deep, and the other end is welded to the operating frame column to form a diagonal support. Functional reuse: The operating frame serves as both an operating platform for personnel to climb and create the structure, as a fixed support foundation for the molding mold, and provides central stability support for the tree tower, counteracting the outward tension of the tower body.

[0055] By adopting the above technical solution, a pioneering built-in central operating frame design was created, replacing the traditional external scaffolding. This completely avoids the operating facilities obstructing the trees' light and ventilation, ensuring normal growth during seedling cultivation and resolving the conflict between operation and growth in the shaping and cultivation of tall trees. The hollow columnar structure balances operating space and structural strength, and the climbing ladder 12 allows personnel to easily reach each level for shaping operations, improving the convenience and safety of cultivation operations. The method of fixing the inclined support 11 to the ground makes the operating frame a stable central support for the tree tower, effectively counteracting the outward tension of the tower-shaped frame and improving the overall structural stability of the tree tower.

[0056] Further, please refer to Figures 1 to 10 As a specific implementation of the tree tower cultivation method provided by the present invention, in step S2, the modeling mold that matches the tree tower design includes a basic vertical mold 2 and a segmented mold 3.

[0057] The basic vertical mold 2 is set on the outside of the hollow operation frame 1 to guide the vertical growth of the base of the seedling and the initial closed loop connection. The basic vertical mold 2 is made of three iron wires 22. The upper ends of the three iron wires 22 are connected in a progressive loop. The lower ends of the three iron wires 22 are all attached to the wooden pole 21, and the upper ends of the three iron wires 22 are level with the upper end of the wooden pole 21.

[0058] The segmented mold 3 is set on the outside of the hollow operation frame 1 and on the upper side of the basic vertical mold 2. It is set in segments along the vertical direction, corresponding to the growth path and connection node of each layer of the tree tower. The segmented mold 3 is also equipped with a path guide structure and point markings that match the main trunk of the seedling.

[0059] Construction of the basic vertical mold 2: Select three 70cm long No. 10 iron wires 22, leaving 10cm of each wire protruding. Connect the upper ends of the three iron wires 22 in a progressive loop to form a triangle. The parallel section is 30cm long and the lower end is 30cm long. Secure the corners with tie wire. Place the mold onto the wooden pole 21 at the planting point (10cm in diameter, 50cm buried in the soil). The parallel section of the iron wire 22 should be level with the upper end of the wooden pole 21, and the lower end should be attached to the wooden pole 21 and secured with tie wire. Two points of the triangle should face outward and one point should face inward.

[0060] Segmented mold 3 fabrication: On the upper side of the basic vertical mold 2, segments are set along the height of the tree tower according to the layered shrinkage requirements. Each segment mold is fixed to the built-in hollow operating frame 1. On the segmented mold 3, a growth path guiding structure matching the main trunk of the seedling is laid with iron wire 22. Clear point marks are set at each layer connection node and branch intersection. The iron wire 22 is tied and fixed to the support ring 13 to ensure the accuracy of the path guidance.

[0061] The molds are used in combination: the basic vertical mold 2 guides the vertical growth of the base of the seedling to the initial closed loop connection, and the segmented mold 3 guides the oblique growth of branches above 2m and the layered connection. The two are connected to form a complete tree tower shaping guidance system.

[0062] By adopting the above technical solution, the shaping mold is divided into a basic vertical mold 2 and a segmented mold 3, achieving precise shaping of the base and layered guidance. This conforms to the layered shrinking structure of the tree tower, which is wider at the bottom and narrower at the top, solving the problem of existing molds having a single shape and being unable to adapt to tall tower shapes. The basic vertical mold 2, through its progressively ringing initial connection, ensures the stable shaping of the seedling base, laying a solid foundation for the subsequent construction of the tower framework and preventing the overall shape from failing due to a loose base. The path guidance structure and point markings of the segmented mold 3 allow the seedling trunk to grow precisely along a preset path, significantly improving the regularity and accuracy of the tree tower shape. At the same time, the segmented setting facilitates step-by-step shaping and subsequent segment dismantling.

[0063] Further, please refer to Figures 1 to 10 As a specific embodiment of the tree tower cultivation method provided by the present invention, the segmented mold 3 adopts a double-layer structure design, including an outer tower body 31 and an inner lining 32.

[0064] The outer tower body 31 is located on the outside of the hollow operating frame 1 and on the upper side of the foundation vertical mold 2; the diameter of the outer tower body 31 gradually decreases upward.

[0065] The inner lining 32 is located between the outer tower body 31 and the hollow operating frame 1, and is divided into five sections from bottom to top; each section of the inner lining 32 adopts a conical structure, and the section of the inner lining 32 at the bottom is defined as the first section.

[0066] The first inner lining section 32 has its large-diameter end located on the lower side and connected to the outer tower body 31; the second inner lining section 32 has its small-diameter end located on the lower side and connected to the small-diameter end of the first inner lining section 32, and its large-diameter end is connected to the outer tower body 31; the third inner lining section 32 has its large-diameter end located on the lower side and connected to the large-diameter end of the second inner lining section 32; the fourth inner lining section 32 has its small-diameter end located on the lower side and connected to the small-diameter end of the third inner lining section 32, and its large-diameter end is connected to the outer tower body 31; the fifth inner lining section 32 has its large-diameter end connected to the top of the outer tower body 31, and its small-diameter end is located on the upper side of the outer tower body 31.

[0067] Outer tower body 31 fabrication: On the upper side of the foundation vertical mold 2, the outer tower body 31 mold is laid out along the layered shrinkage path of the tree tower using wire 22. The diameter of the outer tower body 31 gradually and uniformly decreases from bottom to top. The whole is fixed to the support ring 13 of the hollow operation frame 1, which is adapted to the overall shape of the tree tower, which is larger at the bottom and smaller at the top.

[0068] Inner Liner 32 Fabrication: An inner lining 32 is installed between the outer tower body 31 and the hollow operating frame 1. It adopts a conical structure and is divided into five sections from bottom to top. It is fixed to the hollow operating frame 1 and the outer tower body 31 with iron wire 22. The connection method of each section strictly follows: First section: The larger diameter end is at the bottom and connects to the lower part of the outer tower body 31, while the smaller diameter end is at the top; The second section has the smaller diameter end at the bottom, connecting to the smaller diameter end of the first section, and the larger diameter end at the top, connecting to the corresponding position of the outer tower body 31. The third segment: the larger diameter end is at the bottom, connecting with the larger diameter end of the second segment, and the smaller diameter end is at the top; The fourth section has the smaller diameter end at the bottom, connecting to the smaller diameter end of the third section, and the larger diameter end at the top, connecting to the corresponding position of the outer tower body 31. Fifth section: The larger diameter end is at the bottom and connects to the top of the outer tower body 31, while the smaller diameter end is at the top and extends out of the outer tower body 31, serving as the closing structure at the top of the tree tower.

[0069] The double-layer structure works together: the inner lining 32 provides internal support for the outer tower 31, and the outer tower 31 provides external shaping guidance for the main trunk of the seedling. The two form a double-layer mold structure, which together shape the layered shrinkage skeleton of the tree tower.

[0070] By adopting the above technical solution, a novel double-layered segmented mold structure 3 is created. The inner lining 32 provides internal support for the outer tower body 31, solving the problem of single-layer molds being prone to deformation and unable to support tall tower shapes. This improves the overall structural stability of the mold and ensures the regularity of the tree tower shape. The inner lining 32 adopts a five-segment conical structure with alternating large and small diameter ends, perfectly adapting to the layered shrinkage characteristics of the tree tower, which is larger at the bottom and smaller at the top. At the same time, the five-segment design conforms to the growth rhythm of trees, facilitating step-by-step shaping and cultivation, and reducing the difficulty of shaping tall tree towers.

[0071] The double-layer structure allows the main trunk of the seedling to grow in two separate inner and outer layers, which are then connected at each node to form a double-layered tower-shaped skeleton. This significantly improves the overall structural strength and wind resistance of the tree tower, allowing the living tree tower to withstand greater natural loads.

[0072] Further, please refer to Figures 1 to 10 As a specific embodiment of the tree tower cultivation method provided by the present invention, each inner lining 32 is provided with a support ring 13 at the connection between the large diameter end and the outer tower body 31, and each support ring 13 is fixedly connected to the hollow operation frame 1; the support ring 13 is marked with the connection positioning point of the corresponding seedling trunk.

[0073] Fabrication and installation of support ring 13: 20cm below the connection between the large diameter end of each section of the inner lining 32 and the outer tower body 31, a support ring 13 with a diameter matching the connection is made using 14mm steel bars. The diameter of the support ring 13 gradually decreases with the height of the tree tower, consistent with the shrinkage ratio of the tree tower layers.

[0074] Support ring 13 fixing: Each support ring 13 is welded and fixed to the corresponding position of the hollow operating frame 1 with 16mm horizontal steel bars to ensure the integration of the support ring 13 and the operating frame.

[0075] Positioning point marking: On the circumference of each support ring 13, according to the location of the seedling planting group and layer connection node, the seedling trunk connection positioning point is clearly marked with paint. The number and position of the positioning point correspond one-to-one with the preset number of seedling trunks and connection position.

[0076] Radial steel bars are welded to the inner side of the support ring 13 to form a spoke-type support ring 13, which improves the load-bearing capacity of the support ring 13 and is suitable for mold support of ultra-large tree towers (over 40 meters).

[0077] By adopting the above technical solution, the support ring 13 provides rigid support at the connection between the inner lining 32 and the outer tower body 31, preventing the mold from deforming or shifting due to the growth tension of the seedling trunk and external wind load, thus ensuring the stability and accuracy of the mold shape. The support ring 13 is welded and fixed to the hollow operating frame 1, forming an integrated structure between the shaping mold and the hollow operating frame 1, further improving the stability of the entire mold system and preventing the seedling growth path from shifting due to mold loosening.

[0078] The connection and positioning points on the support ring 13 provide precise positioning for the progressive ring connection of the main trunk of the seedling, allowing operators to quickly complete the connection of branches according to the marked points, improving the efficiency and accuracy of the shaping operation, and avoiding loose shaping due to positioning deviation.

[0079] Further, please refer to Figures 1 to 10 As a specific embodiment of the tree tower cultivation method provided by the present invention, a plurality of triangular ribs 14 are provided between the support ring 13 and the hollow operation frame 1 to improve the stability of the support ring 13.

[0080] Select 14mm steel bars with a length of 1-1.5m as triangular reinforcement 14. Weld one end to the midpoint of the horizontal steel bar connecting the support ring 13, and weld the other end to the column of the operating frame, forming a triangular structure with the column of the operating frame, the horizontal steel bar and the triangular reinforcement 14 as the three sides.

[0081] Each support ring 13 is reinforced with 4-6 triangular ribs 14 at equal intervals, evenly distributed around the circumference of the support ring 13 to ensure consistent reinforcement at all locations. Furthermore, the triangular ribs 14 are welded below the horizontal reinforcing bars to avoid obstructing the growth of the sapling's main trunk and to facilitate shaping.

[0082] By adopting the above technical solution, the mechanical stability of the triangle is utilized, and the connection between the support ring 13 and the operating frame is strengthened and reinforced by the triangular rib 14, which effectively improves the load-bearing capacity and wind resistance and deformation resistance of the support ring 13, and prevents the support ring 13 from sagging or shifting due to the weight of the mold and the tension of the seedling.

[0083] Further, please refer to Figures 1 to 10 As a specific embodiment of the tree tower cultivation method provided by the present invention, the specific operation of planting tree seedlings in groups at the preset planting points 4 in step S3 is as follows: The number of seedlings planted is 30, divided into 10 groups of 3. The 10 groups of seedlings are planted in a circular pattern with equal intervals. The 3 seedlings in each group are planted in an equilateral triangle, with one seedling facing the center of the circle and the other two on the edge of the circle.

[0084] Planting quantity and grouping: Select 10 elm trees, 10 Chinese scholar trees and 10 mulberry trees, and divide them into 10 groups of 3 trees each (one elm tree, one Chinese scholar tree and one mulberry tree). Each group is an independent structural unit, which is adapted to the layered shrinkage structure of the tree tower and 10 equidistant planting points.

[0085] Planting site planning: Use the cross method to determine the tree tower cultivation center, draw a circular planting circle with the center as the center, and determine 10 planting groups on the circumference according to the principle of equal distance. Each group is an independent planting area.

[0086] Planting method within the group: In each group, dig 3 planting pits arranged in an equilateral triangle (50cm apart), plant 3 seedlings in the pits respectively, and adjust the orientation of the seedlings: 1 seedling faces the center of the tree tower circle (fitting the inner lining 32), and the other 2 seedlings face the outside of the circular planting circle (fitting the outer tower body 31). After planting, water thoroughly to ensure that the seedling roots are in close contact with the soil.

[0087] By adopting the above technical solution, the planting quantity of 3 trees in 10 groups is precisely matched with the five-section double-layer mold and 10 layered connection nodes of the tree tower, forming a tower-shaped skeleton with one unit per group and ten groups as a whole, so that the tree tower is subjected to uniform stress and the overall structural stability is improved.

[0088] The equilateral triangle planting method within the group utilizes the stability of triangles to allow each group of seedlings to form an independent and stable structural unit, preventing individual groups of seedlings from tilting due to growth tension, while also providing a convenient foundation for the branch positions to be connected in subsequent progressive circles.

[0089] The design of one tree facing the center and two trees facing outwards precisely matches the inner and outer double-layer structure of the segmented mold 3, allowing the main trunk of the seedling facing the center to grow into the inner lining 32, and the main trunk of the seedling facing outwards to grow into the outer tower body 31. This eliminates the need for significant adjustments to the orientation of the branches later, reducing the difficulty of shaping and improving the accuracy of the shaping.

[0090] Further, please refer to Figures 1 to 10 As a specific embodiment of the tree tower cultivation method provided by the present invention, the specific operation of the progressive ring-forming method in step S4 is as follows: By bending the main trunks of two or more saplings in the same plane in sequence along the same direction, the front end of the main trunk of the next sapling passes through the bend of the main trunk of the previous sapling and bends upward, and so on, a closed loop structure is formed, so that the main trunks of multiple independent saplings are connected to form a stable integrated structure.

[0091] At the junctions of the tree tower layers, the base, and the top, where multiple sapling trunks need to be connected in a closed loop, a progressive circular approach is used. The steps are as follows: 1. Select the main trunks of two or more seedlings that need to be connected, and adjust them to the same plane to ensure that the branches are of similar thickness and growth, and avoid the stronger plant from eating the weaker one.

[0092] 2. Perform directional bending on the main trunk, with the bending angle controlled at 80-90° to ensure the flexibility of the branches and trunk without breaking them.

[0093] 3. In the same clockwise or counterclockwise direction, bend and interlace the main trunk of the seedling in sequence: the front end of the main trunk of the next seedling passes through the bend of the main trunk of the previous seedling, and after passing through, bend upwards at 80-90°, keeping it parallel to the main trunk of the previous seedling. 4. Following this rule, the front end of the trunk of the last seedling passes through the bend of the first seedling to form a closed circle structure. Use wire to tie and fix the intersection and bend, so that the trunks of multiple independent seedlings are connected to form a stable integrated structure.

[0094] By adopting the above technical solution, a pioneering progressive ring-connection method has been developed, solving the industry pain points of difficulty in closing the joints and loose structure in existing multi-tree combination designs. This method achieves a unified closed-loop connection of the main trunks of three or more seedlings, allowing individual seedlings to form a stable overall structure. The progressive ring-interlacing and bending method replaces the traditional approach grafting method, avoiding the problems of strong plants overpowering weaker plants and uneven growth that occur during the approach grafting process. This significantly improves the success rate of multi-tree combination designs and is adaptable to combinations of different tree species, expanding the applicability of the technology.

[0095] The progressively encircling circular closed-loop structure allows the stress at the connecting nodes to be evenly distributed to the trunk of each sapling, avoiding branch breakage caused by localized stress concentration, improving the structural stability of the nodes, and providing a solid node foundation for the construction of the tower-shaped framework.

[0096] Further, please refer to Figures 1 to 10 As a specific embodiment of the tree tower cultivation method provided by the present invention, in step S4, the main trunk of the seedling is connected in a closed loop by progressively forming circles at the base of the tree tower, each layer connection node and the top closing position; for non-closed loop branch intersection nodes, they are fixedly connected by hooking or intertwining.

[0097] Application of progressive ring formation: At the base of the tree tower (at the vertical mold 2), at each layer connection node (at the positioning point of support ring 13), and at the top closing position, the progressive ring formation method is used to form a closed loop connection of the main trunk of the seedling, forming a stable closed node and ensuring the overall stability of the tower-shaped frame.

[0098] Application locations for hooking or entanglement: Differentiated connections are used at non-closed loop branch intersections in the tree tower skeleton (such as the oblique intersection of branches of the outer tower body 31, and the intersection of branches of the inner lining 32 and the outer tower body 31).

[0099] Hooking: Hook the two intersecting main trunks of the seedlings together to form a natural hooking structure, and gently tie them with flexible straps to avoid damaging the bark.

[0100] Intertwining: Twist the two intersecting main trunks of the seedlings together 1-2 times in the same direction to form an intertwined structure. Secure the intertwined parts with wire to ensure the connection strength and not affect the thickening and growth of the branches.

[0101] Reinforcement after connection: After all connection points are completed, check them in a timely manner according to the growth status of the seedlings, and reinforce any loose connection points by binding them again to prevent wind breakage.

[0102] By adopting the above technical solutions, the differentiated connection methods can accurately match the structural requirements of different nodes in the tree tower. Closed nodes are guaranteed to be stable by progressively forming loops, while non-closed-loop intersection nodes are simplified by hooking or wrapping. This achieves the connection principle of prioritizing stability and convenient adaptation, thereby improving the efficiency and quality of tree tower cultivation.

[0103] The progressive ring structure applied to the base, nodes, and closure ensures that the key load-bearing nodes of the tree tower form a stable closed-loop structure, guaranteeing the overall stability of the tower frame and preventing the overall shape from failing due to loosening of key nodes.

[0104] The hooking or wrapping connection method is easy to operate and causes little damage to the seedlings. It is suitable for the connection needs of non-closed loop intersection nodes. At the same time, the flexible binding method can adapt to the thickening growth of the seedling trunk, avoid the connection point from being strangled or broken due to the growth of the trunk, and ensure the long-term healthy growth of the seedlings.

[0105] The combination of the two connection methods enables all nodes of the tree tower skeleton to be effectively connected, forming an integrated structure with strong support at closed nodes and flexible connection at intersecting nodes, which greatly improves the overall structural stability and resistance to natural disasters of the tree tower.

[0106] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
