Description

Technical Field

[0001] This invention belongs to the field of plant grafting and shaping technology, specifically relating to a method for grafting living plants with two rootstocks and one scion, which can be used in garden landscape engineering, courtyard landscaping and various bonsai shaping and cultivation. Background Technology

[0002] Currently, existing techniques for creating arched shapes with living plants mostly rely on external supports to stabilize the plants. These supports, exposed to the outdoor environment for extended periods, are prone to aging, corrosion, and structural damage, directly leading to poor overall structural stability. This necessitates frequent support replacements and maintenance, resulting in high overall maintenance costs. Furthermore, existing techniques easily cause irreversible damage such as splitting, tearing, and breaking of the main stem when bending it, leading to poor healing at grafting points and generally low survival rates in these shaped plants.

[0003] Traditional bonsai styling techniques often involve pruning and wiring individual woody plants for shaping. This not only results in limited styling options and difficulty in creating stable, uniform, integrated arched structures, but also easily damages the phloem of the plant due to prolonged wiring, leading to problems such as branch shrinkage and death. Consequently, the success rate and aesthetic appeal are significantly limited. Current techniques struggle to simultaneously achieve styling stability, cultivation survival rate, scene adaptability, and aesthetic value, exhibiting clear technical shortcomings. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a method for grafting living plants with two rootstocks and one scion.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this invention is a method for grafting living plants using two rootstocks and one scion, comprising the following steps: 1) Material selection steps: Select robust, disease-free, and mechanically undamaged solid woody plants as rootstocks; 2) Planting steps: Plant the two rootstocks symmetrically in the field or in pots according to the desired shape requirements; 3) Bending process: Make a wedge-shaped decompression cut on the outside of the bending position of the main stem of the rootstock, bend the main stem of the rootstock inward and temporarily fix it; 4) Inlay grafting step: The main stems of the two rootstocks are joined at the intersection, and the xylem and bark of the two rootstocks at the joint are cut to make the cambium of the two rootstocks closely aligned and attached. 5) Fixation and maintenance steps: Use grafting film and ties to seal and bind the grafting interface of the main trunk of the two rootstocks, and manage the water and fertilizer of the two rootstocks in a unified manner to promote the healing of the grafting interface. 6) Grafting and trimming steps: Use scions of the same or closely related varieties as the rootstock to graft into the missing or irregular parts of the shape, and trim the outline of the plant. 7) Shaping and unbinding steps: After the grafting interface has completely healed and the xylem of the main stems of the two rootstocks has fused into a unified stress structure, the temporary fixation is removed to form a self-supporting living shape without a support frame.

[0006] As an improvement, the diameter of the main stem of the rootstock can be as small as 0.1 cm. A grafting method for shaping living plants using two rootstocks and one scion is suitable for the cultivation of miniature bonsai.

[0007] As an improvement, the angle of the wedge-shaped decompression incision is 20° to 60°, and the depth of the wedge-shaped decompression incision is 1 / 4 to 1 / 2 of the thickness of the xylem of the rootstock.

[0008] As an improvement, the angle at which the trunk of the rootstock bends inward is 60° to 150°.

[0009] As an improvement, the diameter of the rootstock trunk used for large living arches is ≥3cm, and the height of the rootstock trunk used for large living arches is ≥2.0m.

[0010] As an improvement, the maintenance period is: 3 to 6 months for miniature bonsai cultivation and 10 to 12 months for large living arch construction.

[0011] As an improvement, each of the two rootstocks retains its complete root system, forming a fused structure where both root systems provide nourishment.

[0012] The advantages of this invention compared to existing technologies are as follows: First, it has a wide range of applicable scenarios. The solid woody rootstocks used in this method have a trunk diameter as small as 0.1 cm, which can fully adapt to different scale applications such as miniature bonsai cultivation, medium-sized courtyard landscaping, and large-scale living garden arch construction. Second, it has a high survival rate. By making a wedge-shaped decompression incision on the outside of the bending position on the rootstock's main stem, bending stress can be effectively released, preventing splitting and breakage damage when the rootstock's main stem bends. This provides a stable foundation for the healing of the grafting interface and significantly improves the survival rate of the shaping cultivation. Third, the formed structure is stable and reliable. After grafting and maintenance, the xylem of the two rootstocks fuses into a unified stress-bearing structure, achieving self-support without a support frame. This completely solves the pain points of aging instability and high maintenance costs caused by the reliance on external supports in traditional living shaping. Fourth, the plant exhibits superior growth and maintenance advantages. Both rootstocks retain their complete root systems, forming a fusion structure where both root systems provide nourishment, significantly enhancing plant growth and resilience while reducing overall maintenance costs. Fifth, the finished product boasts high ornamental value. Shaping and refining can be achieved through grafting scions of the same or closely related varieties as the rootstock, ensuring a neat and complete shape and enhancing the ornamental effect and commercial value of the finished product.

[0027] Example 3: Application of a live plant grafting method using two rootstocks and one scion in the construction of medium-sized courtyard arches: This embodiment employs a live plant grafting method using two rootstocks and one scion. The specific implementation steps are as follows: 1) Material selection steps: Select two healthy, disease-free, and mechanically undamaged solid woody Osmanthus plants as rootstocks. The diameter of the main trunk of the rootstock is 1.5cm and the height of the main trunk is 1.8m. 2) Planting steps: Plant the two rootstocks symmetrically at a spacing of 2m according to the target shape requirements of a medium-sized courtyard archway; 3) Bending process: Make a wedge-shaped decompression cut on the outside of the rootstock at a height of 1.2m. The angle of the wedge-shaped decompression cut is 50° and the depth of the wedge-shaped decompression cut is 2 / 5 of the thickness of the xylem of the rootstock.

[0028] In all the above embodiments, each of the two rootstocks retains its complete root system, forming a fused structure with dual root systems providing nourishment throughout the process, ensuring the growth vigor of the rootstocks and the healing efficiency of the grafting interface. In practical applications, the variety and specifications of the rootstocks, the planting spacing, the parameters of the wedge-shaped decompression incision, the bending angle of the rootstock trunk, and the maintenance cycle can be adjusted according to the specifications required for the target shape, all without departing from the core logic of the technical solution of this invention.

[0029] Beneficial effects: A novel grafting method for shaping living plants using two rootstocks and one scion has a wide range of applications, comprehensively covering various scales and types of living plant shaping applications. The solid woody rootstocks selected for this method have a trunk diameter as small as 0.1 cm, making them suitable for indoor and desktop horticulture cultivation of miniature, small, and medium-sized bonsai, as well as for landscaping projects such as medium-sized courtyard living arches and large outdoor living arches. This method fully meets the needs of various living plant shaping applications, including home gardening, private courtyard landscaping, municipal garden construction, and cultural tourism landscape creation.

[0030] A novel grafting method using two rootstocks and one scion for shaping living plants significantly reduces the risk of plant damage during handling and greatly improves the survival rate of bending and grafting healing. This method involves making a wedge-shaped decompression incision on the outer side of the bending point on the main stem of the rootstock. This effectively releases the bending stress generated during the inward bending of the rootstock's main stem, preventing splitting, tearing, and breakage during the bending process. It also reduces irreversible damage to the xylem and phloem of the rootstock's main stem, providing a stable physiological basis for the subsequent healing of the graft union between the two rootstocks and significantly improving the survival rate throughout the entire shaping process.

[0031] A novel grafting method using two rootstocks and one scion for shaping living plants results in a stable and reliable plant structure that achieves self-support without external supports, completely eliminating reliance on external structures. This method involves joining the main stems of two rootstocks at their intersection, cutting the corresponding xylem and bark to ensure close alignment and adhesion of the cambium layers of the two rootstock stems. After maintenance, the grafting interface heals completely, and the xylem of the two rootstock stems fuses into a unified load-bearing structure, forming a unified living plant model. This method achieves long-term stable self-support without the need for external supports, fundamentally solving the industry pain points of traditional living plant shaping methods that rely on external supports, such as aging, corrosion, structural instability, and high maintenance and replacement costs.

[0032] A novel grafting method using two rootstocks and one scion produces plants with vigorous growth, strong resistance to adverse conditions, and low maintenance costs throughout their entire life cycle. In this method, each rootstock retains its complete root system, forming a fused structure with dual root systems providing shared nutrition. Compared to traditional single-plant grafting, this dual root system provides more abundant nutrients and water, significantly enhancing the plant's overall growth, environmental resistance, and tolerance to pests and diseases. After shaping, no complex periodic reshaping or support maintenance is required, greatly reducing the difficulty and cost of maintaining the plant throughout its life cycle.

[0033] A grafting method using two rootstocks and one scion to cultivate live plant ornamental plants with high ornamental value, good shape regularity, and integrity. This method includes a dedicated re-grafting and trimming step, using scions of the same or closely related varieties as the rootstocks to fill in gaps or irregularities in the shape, while simultaneously refining the plant's outline. This ensures the final live plant ornamentation has a complete and regular shape. Furthermore, pruning and wiring techniques can be used to further enrich the shaping details, comprehensively enhancing the overall ornamental effect and commercial value of the plant.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
