Description

Technical Field

[0001] This utility model belongs to the field of horticultural tool technology, and in particular relates to a bagging and fixing device for plant grafting. Background Technology

[0002] Plant grafting is a crucial technique in horticulture and agricultural production, and its survival rate directly affects the efficiency and economic benefits of seedling propagation. After grafting, the scion is extremely fragile before callus tissue forms and new vascular connections are established, making it highly susceptible to drying out and dying due to water transpiration. Therefore, creating and maintaining a high-humidity, undisturbed local microenvironment is a key step in ensuring successful grafting.

[0003] Currently, the most common maintenance method is the simple bagging method, which involves covering the scion with a small plastic bag or a special grafting bag and securing the bag opening to the rootstock with rope or tape. Alternatively, an elastic grafting film can be used to tightly wrap the graft union.

[0004] However, existing technologies have the following drawbacks: Insufficient space can easily cause physical damage: Simple bagging relies entirely on the rootstock or scion for support, and the bag is extremely prone to collapsing due to wind, rain, or condensation, directly contacting the scion's tender buds or callus tissue. This not only interferes with its growth, but more seriously, under sunlight, the temperature of the tightly adhered plastic film rises sharply, directly scorching or burning the scion tissue, leading to grafting failure.

[0005] The microenvironment control is crude, and the hardening-off process is abrupt: existing bagging methods typically leave the scions in either a completely sealed or completely open state. When it is necessary to harden off the scions, operators can only ventilate by tearing off the tape, poking holes in the bag, or removing the bag directly. This method causes drastic changes in humidity and temperature, making it difficult for the scions to adapt to the sudden exposure to dry, strong light, which can easily lead to bud drop and wilting, thus compromising the survival rate of the hardened-off seedlings.

[0006] The securing method is rudimentary and lacks stability: relying on rope binding makes it difficult to control the seal and easily damages the bark of the rootstock. The bag as a whole lacks independent support, has weak wind resistance, and is easily blown off.

[0007] Inconvenient to operate and difficult to reuse: The process of bagging, binding, punching holes and removing plastic bags is cumbersome, and plastic bags are easily damaged and usually cannot be reused, which increases material consumption and operating costs.

[0008] In summary, existing grafting and maintenance tools have significant shortcomings in terms of the reliability of physical protection and the precise controllability of microenvironment transition, and there is an urgent need for a device that can solve the above problems. Utility Model Content

[0009] In view of the technical problems existing in the background art, this utility model provides a bagging and fixing device for plant grafting.

[0010] To achieve the above objectives, the technical solution provided by this utility model is as follows: A plant grafting bag fixer, comprising, The supporting frame is a ring-shaped frame formed by bending a tough material, used to provide support space for the bag; A bag is fitted over the outside of the supporting frame; A closing adjustment mechanism is provided at the bottom of the support frame to tighten and fix the support frame and the bottom side of the bag to the outer wall of the rootstock. The support fixture includes a connecting component and an insertion fixing component, wherein the connecting component is detachably connected to the support frame; and the insertion fixing component is used to insert into the cultivation substrate to fix the entire bagging fixture to the potted container.

[0011] Optionally, the bottom side of the support frame is provided with an annular hook, and the closing adjustment mechanism is a pull rope inserted inside several hooks for tightening the support frame.

[0012] Optionally, the connecting assembly includes a first horizontal insertion part, a first vertical adjustment part, a bending part, a second vertical adjustment part, a diagonal brace part, and a second horizontal insertion part connected in sequence; the bending part is located on the upper side of the first horizontal insertion part, and a connecting rod extends horizontally from one side of the hook head, the connecting rod being inserted into the inner hole of the first horizontal insertion part; a buckle is detachably provided on the bending part, the buckle pressing the bag tightly onto the support frame.

[0013] Optionally, the first vertical adjustment part, the bending part, and the second vertical adjustment part are connected in sequence to form a U-shaped clamp, with the bottom ends of the first vertical adjustment part and the second vertical adjustment part close to each other; the first horizontal insertion part extends horizontally outward from the first vertical adjustment part; when the first horizontal insertion part is pulled horizontally, the U-shaped clamp undergoes elastic deformation, causing the lower parts of the first vertical adjustment part and the second vertical adjustment part to move away from each other; after the pulling force is removed, the U-shaped clamp returns to its original shape under its own elastic action.

[0014] Optionally, the diagonal brace extends obliquely to the bottom from the second vertical adjustment part, and the second horizontal insertion part extends horizontally outward from the diagonal brace.

[0015] Optionally, the insertion and fixing assembly includes a pressure ring and a plug rod slidably disposed inside the pressure ring, wherein the second horizontal insertion part is inserted into the inner hole of the pressure ring, and the plug rod is used to be inserted into the cultivation substrate for fixing.

[0016] Optionally, a sleeve is provided on the upper end face of the pressure ring, and the insertion rod is disposed inside the sleeve.

[0017] Optionally, the upper ends of some of the support frames are connected to the mounting block.

[0018] Optionally, the bag is provided with a plurality of ventilation holes, and the ventilation holes are detachably provided with sealing parts to realize the closure or opening of the ventilation holes.

[0019] Optionally, the ventilation holes include a first ventilation hole disposed at the top of the bag and a plurality of second ventilation holes disposed around the circumference of the bag.

[0020] This utility model has the following advantages and beneficial effects: 1. Excellent physical isolation effect, preventing contact damage. The rigid combination of a support skeleton made of tough materials (such as PVC-coated steel wire) and support fasteners provides a stable, three-dimensional support framework for the bagging. This framework ensures that the bag maintains a safe distance from the scion and grafting interface under any circumstances (such as wind, rain, or internal condensation), fundamentally eliminating scion burns, adhesions, and physical friction damage caused by collapse and contact in traditional bagging, thus creating an undisturbed growth space for callus tissue.

[0021] 2. The microenvironment transition is stable and controllable, significantly improving the survival rate of seedlings after hardening off. This method involves finely and gradually controlling the microenvironment (humidity, temperature, and ventilation) inside the bag by tightening and adjusting mechanisms (such as ring hooks and pull ropes). Users can continuously or in stages adjust the size of the opening at the bottom of the bag according to the growth stage of the grafted seedlings and weather conditions, achieving a smooth and controllable transition from "high humidity and airtightness" to "ventilated and dryness." This greatly alleviates the physiological stress on the scions caused by sudden environmental changes during the hardening-off period, effectively preventing bud drop and wilting, thereby significantly improving the success rate and safety of the hardening-off process in the later stages of grafting.

[0022] 3. Stable and convenient installation, with wide applicability. The support and fixing component can be directly and securely inserted into the cultivation substrate through its insertion and fixing part. Combined with the adjustable bottom tightening mechanism, it forms a stable "top support and bottom fixation" system. This fixing method does not rely on tightly binding the rootstock branches, avoiding damage to them, and significantly enhancing wind resistance. At the same time, its modular design allows it to easily adapt to different sizes of potted plants, seedbeds, or ground planting environments, making it highly versatile and practical.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Example like Figures 1-10 As shown, a plant grafting bag fixer includes a support frame 2, a bag 3, an opening adjustment mechanism, and support fixing components.

[0028] The support frame 2 is a ring frame formed by bending a tough material. Several support frames 2 are provided to provide support space for the bag 3. The bag 3 is fitted onto the outside of the support frame 2 to achieve shaping installation.

[0029] The closing adjustment mechanism is located at the bottom of the support frame 2 and is used to tighten and fix the bottom sides of the support frame 2 and the bag 3 to the outer wall of the rootstock 12. The closing adjustment mechanism can adjust the opening on the bottom side of the bag 3, thereby adjusting the size of the opening between the rootstock 12 and the bag 3. Immediately after grafting, the closing adjustment mechanism completely tightens the bag 3 against the outer wall of the rootstock 12 and seals it. As the grafting time increases, the closing adjustment mechanism is gradually loosened, allowing the bottom side of the bag 3 to move away from the rootstock 12, opening a gap, and achieving a smooth and controllable transition from "high humidity and sealing" to "ventilation and drying".

[0030] The support fixture includes a connecting component 4 and an insertion fixing component. The connecting component 4 is detachably connected to the support frame 2. The insertion fixing component is used to insert into the cultivation substrate 11 to fix the entire bagging fixture to the potted container 1.

[0031] This invention provides a stable and three-dimensional support frame for the bag 3 through the rigid cooperation between the support skeleton 2, made of a tough material (such as plastic-coated steel wire), and the support fixing component. This frame ensures that the bag maintains a safe distance from the scion 13 and grafting interface under any circumstances (such as wind, rain, or internal condensation), fundamentally eliminating the burns, adhesions, and physical friction damage to the scion 13 caused by the collapse and contact of traditional bags 3, thus creating an undisturbed growth space for callus tissue.

[0032] This invention utilizes a tightening and adjusting mechanism (such as the annular hook 21 and the pull rope 5) to precisely and gradually control the internal microenvironment (humidity and temperature) of the bag 3. Users can continuously or segmentally adjust the size of the opening at the bottom of the bag according to the growth stage of the grafted seedling and weather conditions, achieving a smooth and controllable transition from "high humidity and airtightness" to "ventilated and dryness." This greatly alleviates the physiological stress caused by sudden environmental changes during the hardening-off period of the scion 13, effectively preventing bud drop and wilting, thereby significantly improving the success rate and safety of the hardening-off process in the later stages of grafting.

[0033] like Figures 1-10As shown, the bottom side of the support frame 2 is provided with annular hooks 21. The support frame 2 is located inside the bag 3 on the upper side to support the bag 3, while the hooks 21 extend to the outside of the bag 3 on the lower side for easy threading of ropes. The annular frame formed by the support frame 2 has a structure that is wider at the top and narrower at the bottom, with the opening closed at the bottom. The closing adjustment mechanism is a pull rope 5 threaded inside several hooks 21 to tighten the support frame 2. By pulling the rope 5, all the support frames 2 can be tightened or loosened on the lower side to achieve the closing operation.

[0034] like Figures 1-10 As shown, the connecting component 4 includes a first horizontal insertion part 45, a first vertical adjustment part 44, a bending part 43, a second vertical adjustment part 42, a diagonal brace part 41, and a second horizontal insertion part 46 connected in sequence. The first horizontal insertion part 45, the first vertical adjustment part 44, the bending part 43, the second vertical adjustment part 42, the diagonal brace part 41, and the second horizontal insertion part 46 are made of a tough material (such as plastic-coated steel wire) by multiple bending in one piece.

[0035] like Figures 1-10 As shown, the bent portion 43 is located above the first horizontal insertion portion 45. A connecting rod 22 extends horizontally from one side of the hook head 21. The connecting rod 22 is inserted into the inner hole at the end of the first horizontal insertion portion 45 to connect the connecting component 4 and the hook head 21. A buckle 7 is detachably provided on the bent portion 43. Two slots 71 are symmetrically provided on the buckle 7. The buckle 7 is connected to the bent portion 43 and the support frame 2 through the slots 71, and the buckle 7 presses the bag 3 tightly onto the support frame 2. This design, with the bottom hook head 21 connected to the first horizontal insertion portion 45 and the upper bent portion 43 connected to the support frame 2, provides double-layer fixation, further increasing the overall support stability of the support frame 2.

[0036] like Figures 1-10 As shown, the first vertical adjustment part 44, the bending part 43, and the second vertical adjustment part 42 are connected in sequence to form a U-shaped clamp, with the bottom ends of the first vertical adjustment part 44 and the second vertical adjustment part 42 close to each other; the first horizontal insertion part 45 extends horizontally outward from the first vertical adjustment part 44; when the first horizontal insertion part 45 is pulled horizontally, the U-shaped clamp undergoes elastic deformation, causing the lower parts of the first vertical adjustment part 44 and the second vertical adjustment part 42 to move away from each other; after the pulling force is removed, the U-shaped clamp returns to its original shape under its own elastic action.

[0037] Furthermore, the inclined support 41 extends obliquely to the bottom from the second vertical adjustment part 42, and the second horizontal insertion part 46 extends horizontally outward from the inclined support 41. The inclined support 41 extends to the bottom, which facilitates the suspension and support of the entire support frame 2, thereby reducing the volume of the bag 3 and avoiding the situation where the traditional bag 3 needs to completely cover the rootstock 12, scion 13 and container 1, resulting in the bag 3 being too large and wasteful.

[0038] Furthermore, the insertion fixing component includes a pressure ring 6 and a plug 61 slidably disposed inside the pressure ring 6. The second horizontal insertion part 46 is inserted into the inner hole on the side of the pressure ring 6. The plug 61 is used to insert into the cultivation substrate 11 for fixing and to press the pressure ring 6 onto the cultivation substrate 11, thereby achieving stable fixing of the entire fixing device.

[0039] Furthermore, a sleeve 62 is provided on the upper end face of the pressure ring 6, and the insertion rod 61 is disposed inside the sleeve 62.

[0040] Furthermore, the upper ends of several of the support frames 2 are connected to the mounting block 23 to enhance the overall strength of the support frame 2.

[0041] In this utility model, the bag 3 is provided with a plurality of ventilation holes 31, and the ventilation holes 31 are detachably provided with sealing parts to realize the closure or opening of the ventilation holes 31.

[0042] Furthermore, the vent 31 includes one vent 31 disposed at the top of the bag 3 and several vent 31 disposed around the circumference of the bag 3. The sealing member includes a first sealing member 33 and a second sealing member 32. The first sealing member 33 is detachably disposed in the vent 31 at the top, and the second sealing member 32 is detachably disposed in the vent 31 on the side.

[0043] In this invention, the sealing element uses Velcro. Specifically, a hook-and-loop fastener is fixed to one side of the vent 31, and a textured fastener is fixed to the corresponding side. By bonding the hook-and-loop fastener and the textured fastener together, the vent 31 can be completely sealed.

[0044] During the grafting process, the tightening and tightening mechanism and the opening of the corresponding ventilation holes 31 are adjusted according to the grafting conditions to achieve precise and gradual control of the internal microenvironment (humidity, temperature, and ventilation) of the bag 3. Users can continuously or in stages adjust the number of openings at the bottom of the bag and the side ventilation holes 31 according to the growth stage of the grafted seedlings and the weather conditions to achieve a smooth and controllable transition from "high humidity and airtightness" to "ventilated and dryness".

[0045] This design ensures that the entire fixture can be installed quickly and easily, and safely without contact with the grafted rootstock 12 and scion 13.

[0046] The operating steps are as follows: Before installing the fixing device inside the container 1, first install the bag 3 on the outside of the support frame 2 to complete the initial installation. Then, insert the connecting rod 22 into the inner hole of the first horizontal insertion part 45 to fix the bottom side of the support frame 2. At this time, the upper buckle 7 is not installed. Align the entire fixing device with the top of the scion 13 and place it vertically downward. Place the rootstock 12 and scion 13 inside the fixing device (support frame 2 and bag 3) until the second horizontal insertion part 46 on the bottom side of the fixing device is in close contact with the upper side of the cultivation substrate 11 to achieve the initial support of the entire fixing device.

[0047] Then, tighten the rope 5 to secure the bottom of the support frame 2 and the bag 3 to the outer wall of the rootstock 12. During the tightening of the support frame 2, the first horizontal insertion part 45 is pulled horizontally, causing the lower parts of the first vertical adjustment part 44 and the second vertical adjustment part 42 to move away from each other, allowing for adaptive deformation. After the bottom of the support frame 2 and the bag 3 is fully tightened, the upper buckle 7 is fastened to the support frame 2 for complete fixation. Then, install the pressure ring 6, connect it to the second horizontal insertion part 46, and press the insertion rod 61 to insert it into the cultivation substrate 11 to achieve complete fixation of the device.

[0048] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
