Description

Technical Field

[0001] This utility model relates to the field of fruit tree cultivation technology, specifically to a seedling tray that facilitates grafting of apple seedlings. Background Technology

[0002] Existing apple seedling grafting trays lack targeted structural design. After grafting, there is no effective means to fix the rootstock and scion, which is prone to misalignment due to external forces such as handling and watering, resulting in callus tissue breakage and reducing the grafting success rate. In addition, the grafting site is fragile and unprotected, and is easily damaged by substrate friction and bumps. At the same time, without a stable support structure, the grafted seedling is prone to falling over, affecting growth.

[0003] Therefore, this utility model provides a seedling tray that facilitates apple seedling grafting. The grafting point is fixed by a fixed semi-cylindrical buckle to prevent displacement and form a protective barrier. A triangular support is formed by a support rod, a displacement block, and the tray frame to prevent lodging. The displacement block can be adjusted along the sliding groove to adapt to seedlings of different sizes. This improves the shortcomings of existing seedling trays, such as poor fixation, lack of protection, and easy lodging, and meets the urgent needs of the fruit tree cultivation industry for the protective and lodging-resistant functions of apple seedling grafting trays. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a seedling tray for easy grafting of apple seedlings, comprising: a tray frame, a soil-holding box fixedly connected to the bottom outer wall of the tray frame, sliding grooves symmetrically opened on the outer wall of the soil-holding box, and displacement blocks slidably connected to the inner wall of the sliding grooves; a support rod rotatably connected to the outer wall of the displacement block, and a fixing half-cylinder rotatably connected to the outer wall of the end of the support rod away from the displacement block, and locking wedges and female buckles symmetrically fixedly connected to the outer wall of the fixing half-cylinder. In use, this seedling tray, with the tray frame as the overall support framework, has a soil-holding box fixedly connected to its bottom outer wall for containing seedling substrate and fixing rootstock roots. The symmetrically opened sliding grooves on the outer wall of the soil-holding box provide a horizontal sliding track for the displacement blocks. Limiting holes opened on the outer walls of both the tray frame and the displacement blocks, in conjunction with slidably insertable limiting wedges, can lock the position of the displacement blocks, preventing them from sliding arbitrarily during seedling cultivation, thus laying the foundation for the stability of the subsequent support structure.

[0005] Preferably, both the tray frame and the displacement block have limiting holes on their outer walls. Limiting wedges are slidably connected to the outer walls of these limiting holes. As a core component designed for the grafting point of apple seedlings, the fixing half-tube extends its function through a rotatable connection with the support rod. The end of the support rod away from the fixing half-tube is rotatably connected to the displacement block, forming a flexible connection structure. The locking wedges symmetrically fixed to the outer walls of the fixing half-tubes can be directly snapped together with the female buckle. In use, the two fixing half-tubes are wrapped around the seedling stem from both sides of the grafting point, and the locking wedges are inserted into the buckle grooves of the female buckle to achieve tightness or looseness. With controllable fixation, covering mainstream grafting scenarios such as budding and branch grafting, the fixation half-tube is not only a fixing component but also a protective barrier for the grafting site. Made of rigid PP plastic, it forms a ring-shaped protective shell after wrapping the grafting site, effectively blocking external damage such as handling collisions, substrate friction, and insect damage during seedling cultivation, preventing the fragile grafting site from breaking. At the same time, the inner wall of the fixation half-tube is smooth and burr-free, so it will not scratch the seedling stem. It can cover a certain range above and below the grafting site, ensuring the protective effect while leaving space for the bud to be exposed, without affecting the normal growth of the scion.

[0006] Preferably, the locking wedge and the outer wall of the female buckle are snapped together. To solve the problem of apple seedlings easily falling over after grafting, the seedling tray uses a fixed half-cylinder, a support rod, and a tray frame to form a triangular support structure. Utilizing the strong mechanical properties of a triangle's stability, it provides reliable support for the grafted seedling. The rotating connection design at both ends of the support rod allows for fine-tuning of the angle, ensuring that the fixed half-cylinder is always perpendicular to the grafted seedling stem. The displacement block slides horizontally along the sliding groove, adjusting the horizontal angle between the support rod and the tray frame according to the seedling height. For example, when the seedling is taller, the displacement block can slide inwards. In terms of improving stability, this seedling tray design for easy apple seedling grafting combines convenience, stability, and versatility. It requires no complicated tools, and a single person can complete the operation by sliding and locking the displacement block and connecting the fixation half-tube with a snap fastener. The triangular support can reduce the lodging rate of grafted seedlings, and the fixation and protection function of the fixation half-tube can promote callus formation. At the same time, it is compatible with different rootstock varieties and grafting methods, which can meet the diverse needs of apple seedling cultivation and effectively solve the problems of difficult fixation, easy damage, and easy lodging of grafted seedlings in existing technologies.

[0007] The beneficial effects of this utility model are as follows: 1. This utility model, by setting a fixing half-cylinder and using a locking wedge and a female buckle to connect, can stably fix the grafting point, avoid misalignment of the rootstock and scion, and ensure callus formation; at the same time, the fixing half-cylinder forms an annular protective shell, which can block external forces such as transportation collisions and matrix friction, and prevent damage to the grafting point.

[0008] 2. This utility model uses a triangular support structure consisting of a fixed half-cylinder, a support rod, and a plate frame. The stability of the triangle prevents the grafted seedlings from falling over. The displacement block can be adjusted along the sliding groove, and the angle of the support rod can be finely adjusted to accommodate grafted seedlings of different heights.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0012] Example: Please see Figure 1 - Figure 5 This utility model provides a technical solution: a seedling tray for easy grafting of apple seedlings, comprising: a tray frame 1, a soil-holding box 2 fixedly connected to the bottom outer wall of the tray frame 1, sliding grooves 3 symmetrically formed on the outer wall of the soil-holding box 2, and displacement blocks 4 slidably connected to the inner wall of the sliding grooves 3; a support rod 7 rotatably connected to the outer wall of the displacement block 4, and a fixing half-cylinder 8 rotatably connected to the outer wall of the end of the support rod 7 away from the displacement block 4; and locking wedges 9 and female buckles 10 symmetrically fixedly connected to the outer wall of the fixing half-cylinder 8, for use as... As a core component designed for the grafting site of apple seedlings, the fixed half-cylinder 8 extends its function through a rotatable connection with the support rod 7. The end of the support rod 7 away from the fixed half-cylinder 8 is rotatably connected to the displacement block 4, forming a flexible connection structure. The locking wedges 9, which are symmetrically fixed on the outer wall of the fixed half-cylinder 8, can be directly snapped together with the female buckle 10. When in use, the two fixed half-cylinders 8 are wrapped around the seedling stem from both sides of the grafting site, and the locking wedges 9 are inserted into the buckle groove of the female buckle 10 to achieve a controllable fixation, covering mainstream grafting scenarios such as bud grafting and branch grafting.

[0013] Both the tray frame 1 and the displacement block 4 have limiting holes 5 on their outer walls. The outer walls of the limiting holes 5 are slidably connected to limiting wedges 6. The fixing half-cylinder 8 is not only a fixing component, but also a protective barrier for the grafting point. It is made of rigid PP plastic and can form a ring-shaped protective shell after wrapping the grafting point. It can effectively block external forces such as collisions during seedling cultivation, substrate friction, and insect damage, and prevent the fragile grafting point from breaking. At the same time, the inner wall of the fixing half-cylinder 8 is smooth and burr-free, so it will not scratch the seedling stem. It can cover a certain range above and below the grafting point. While ensuring the protective effect, it can also leave space for the bud to be exposed, so as not to affect the normal growth of the scion.

[0014] The locking wedge 9 and the female buckle 10 are connected by a snap-fit ​​on the outer wall. To solve the problem of apple seedlings easily falling over after grafting, the seedling tray uses the fixed half-cylinder 8, the support rod 7 and the tray frame 1 to form a triangular support structure. With the strong mechanical properties of the triangle, it provides reliable support for the grafted seedling. The rotating connection design at both ends of the support rod 7 can finely adjust the angle to ensure that the fixed half-cylinder 8 is always perpendicular to the stem of the grafted seedling. The displacement block 4 slides horizontally along the sliding groove 3, which can adjust the horizontal angle between the support rod 7 and the tray frame 1 according to the height of the seedling. For example, when the seedling is tall, the displacement block 4 can be slid inward to further improve stability.

[0015] Working principle: In use, this seedling tray uses the tray frame 1 as the overall support frame. The bottom outer wall of the tray is fixedly connected to the soil box 2, which is used to hold the seedling substrate and fix the rootstock root system. The sliding grooves 3 symmetrically opened on the outer wall of the soil box 2 provide a horizontal sliding track for the displacement block 4. The limiting holes 5 opened on the outer walls of both the tray frame 1 and the displacement block 4, together with the slidable limiting wedges 6, can lock the position of the displacement block 4 and prevent it from sliding at will during the seedling process, laying the foundation for the stability of the subsequent support structure.

[0016] As a core component designed for apple seedling grafting, the fixed half-tube 8 extends its function through a rotatable connection with the support rod 7. The end of the support rod 7 away from the fixed half-tube 8 is rotatably connected to the displacement block 4, forming a flexible connection structure. The locking wedges 9, which are symmetrically fixed on the outer wall of the fixed half-tube 8, can be directly snapped together with the female buckle 10. When in use, the two fixed half-tubes 8 are wrapped around the seedling stem from both sides of the grafting point. The locking wedges 9 are inserted into the buckle groove of the female buckle 10 to achieve a controllable fixation, covering mainstream grafting scenarios such as bud grafting and branch grafting.

[0017] The fixation half-tube 8 is not only a fixing component, but also a protective barrier for the grafting point. It is made of rigid PP plastic and forms a ring-shaped protective shell after wrapping the grafting point. It effectively blocks external forces such as collisions during seedling transportation, substrate friction, and insect damage, preventing the fragile grafting point from breaking. At the same time, the inner wall of the fixation half-tube 8 is smooth and burr-free, so it will not scratch the seedling stem. It can cover a certain area above and below the grafting point. While ensuring the protective effect, it can also leave space for the bud to be exposed, so as not to affect the normal growth of the scion.

[0018] To address the issue of apple seedlings easily lodging after grafting, this seedling tray utilizes a triangular support structure formed by the fixed half-cylinder 8, support rod 7, and tray frame 1. Leveraging the strong stability of a triangle, it provides reliable support for the grafted seedling. The rotating connection design at both ends of the support rod 7 allows for fine-tuning of the angle, ensuring that the fixed half-cylinder 8 remains perpendicular to the seedling stem. The displacement block 4 slides horizontally along the sliding groove 3, adjusting the horizontal angle between the support rod 7 and the tray frame 1 according to the seedling height. For example, when the seedling is taller, the displacement block 4 can slide inwards to further enhance stability.

[0019] Overall, this seedling tray design for easy apple seedling grafting combines convenience, stability, and versatility. It requires no complicated tools, and a single person can complete the operation by sliding and locking the displacement block and connecting the fixation half-tube with a snap fastener. The triangular support can reduce the lodging rate of grafted seedlings, and the fixation and protection functions of the fixation half-tube can promote callus formation. At the same time, it is compatible with different rootstock varieties and grafting methods, which can meet the diverse needs in the apple seedling cultivation process and effectively solve the problems of difficult fixation, easy damage, and easy lodging of grafted seedlings in existing technologies.
