[0027] like Figures 1-3As shown, the multifunctional tobacco seedling grafting clip provided in this embodiment includes: a left arc-shaped clip 1 and a right arc-shaped clip 2 arranged opposite to each other. The interior of the left arc-shaped clip 1 and the right arc-shaped clip 2 are both hollow structures. The left arc-shaped clip 1 and the right arc-shaped clip 2 are arranged in a circle with a cavity 4 in the middle. The two opposite ends of the left arc-shaped clip 1 and the right arc-shaped clip 2 are the outer end and the inner end, respectively. A left holding plate 6 and a right holding plate 7 are respectively provided on the outer side of the inner end of the left arc-shaped clip 1 and the right arc-shaped clip 2. The top of the left arc-shaped clip 1 and the right arc-shaped clip 2 are detachably provided with a top cover. Each top cover is provided with an injection hole 3. The injection hole 3 is used to inject disinfectant and / or plant hormone solution. The inner wall of the cavity 4 is provided with a plurality of ventilation holes 9.

[0028] The plant hormone solution injected through the injection hole 3 includes indoleacetic acid (IAA) or gibberellin (GA). Indoleacetic acid (IAA) promotes wound healing, vascular bundle establishment, and xylem redevelopment during grafting; gibberellin (GA) is important for wound healing during cell expansion; it can enhance scion vigor and promote grafted plant growth by regulating the transport balance between cytokinin (CTK) and abscisic acid (ABA). This invention injects plant hormone solution or disinfectant through the injection hole 3, which then enters the graft union of the tobacco seedling through the ventilation hole 9, improving grafting wound healing, plant survival rate, and promoting early and rapid growth. It should be noted that this invention does not specifically limit the type of disinfectant and plant hormone solution injected through the injection hole 3. In one embodiment, disinfectant can be injected alone; in another embodiment, one plant hormone solution can be injected alone or two or more plant hormone solutions can be injected simultaneously; in yet another embodiment, disinfectant and one or more plant hormone solutions can be injected simultaneously. This invention does not specifically limit the specific types of plant hormone solutions injected through the injection hole 3.

[0029] Furthermore, each of the injection holes 3 is provided with a cap, which can prevent dust, impurities and other contaminants from entering the injection hole 3 and affecting the growth of tobacco seedlings.

[0030] Furthermore, the hollow structures of the left arc-shaped clip 1 and the right arc-shaped clip 2 are replaceably equipped with absorbent material. This absorbent material can absorb disinfectant and plant hormone solution, ensuring that the disinfectant and plant hormone solution seep out evenly and slowly into the grafting interface of the tobacco seedlings, avoiding waste. In a specific implementation, after the absorbent material in the left arc-shaped clip 1 or the right arc-shaped clip 2 becomes saturated, the top cover of the current arc-shaped clip is opened, the absorbent material is removed, and new absorbent material is placed in. In one embodiment of this invention, the absorbent material is a sterile sponge. It should be noted that this invention does not specifically limit the type of absorbent material.

[0031] Furthermore, the inner walls of the left arc-shaped clip 1 and the right arc-shaped clip 2 are provided with sealing sleeves, and each sealing sleeve is respectively fitted to the left arc-shaped clip 1 and the right arc-shaped clip 2. The sealing sleeves prevent disinfectant and plant hormone solutions from corroding the left arc-shaped clip 1 and the right arc-shaped clip 2, thus avoiding affecting their service life. In one embodiment of this utility model, the sealing sleeves are made of rubber material. It should be noted that this utility model does not specifically limit the material and thickness of the sealing sleeves.

[0032] During the process, hold the left holding plate 6 and the right holding plate 7 inwards to open the outer ends of the left arc-shaped clamp 1 and the right arc-shaped clamp 2, and clamp them onto the grafting interface of the tobacco seedling. This method is suitable for fixing tobacco seedlings of different diameters. Plant hormone solution or disinfectant is injected through the injection hole 3 and then enters the grafting interface of the tobacco seedling through the ventilation hole 9. This can effectively reduce pathogen infection, improve the healing of grafting wounds and the survival rate of plants, and promote the healthy development and growth of tobacco plants. At the same time, the ventilation hole 9 can also maintain air circulation, ensure good air permeability of the grafting interface, and maintain tightness.

[0033] Furthermore, a first spring 5 is provided between the left holding plate 6 and the right holding plate 7; the first spring 5 is circular in shape. It should be noted that the shape of the first spring 5, the included angle between the left arc-shaped clamp 1 and the right arc-shaped clamp 2, and the relative position of the first spring 5 between the left holding plate 6 and the right holding plate 7 are not specifically limited in this utility model.

[0034] Furthermore, the angle between the left holding plate 6 and the left arc-shaped clamp 1 is an acute angle, and the angle between the right holding plate 7 and the right arc-shaped clamp 2 is an acute angle. The angle between the left arc-shaped clamp 1 and the right arc-shaped clamp 2 is 30°-60°, for example, 45°.

[0035] Furthermore, the vent holes 9 on the inner wall of the cavity 4 corresponding to the left arc-shaped clamp 1 and the right arc-shaped clamp 2 are evenly distributed in a matrix. The vent holes 9 are circular in shape, and the diameter of the vent holes 9 is 3mm-7mm, for example, 5mm. It should be noted that this utility model does not specifically limit the number, distribution, or diameter of the vent holes 9.

[0036] Furthermore, the outer ends of the left arc-shaped clamp 1 and the right arc-shaped clamp 2 are respectively provided with a small plate 11 and a second spring 10 mounted on the small plate 11, wherein the small plate 11 is located on the inner side of the outer end, and the second spring 10 is located on the outer side of the outer end. The small plate 11 and the second spring 10 ensure both sufficient buffer space and that the connection between the outer ends of the left arc-shaped clamp 1 and the right arc-shaped clamp 2 is closed inwards, ensuring both breathability and moisture retention. In one embodiment of this utility model, the small plate 11 is an iron plate, and the small plate 11 and the second spring 10 corresponding to the left arc-shaped clamp 1 and the right arc-shaped clamp 2 are staggered on the outer ends. It should be noted that this utility model does not specifically limit the material of the small plate 11, the method of fixing the second spring 10 to the small plate 11, or the relative positions of the small plate 11 and the second spring 10 on the outer ends.

[0037] The multifunctional tobacco seedling grafting clip provided in this embodiment of the invention has a simple structure and is easy to use. It not only has the basic functions of a grafting clip, but can also add disinfectant and plant hormone solution, thereby effectively reducing pathogen infection, improving the healing ability of grafting wounds and the survival rate of plants, and promoting the healthy development and growth of tobacco plants.
