Description

Technical Field

[0001] The invention relates to the technical field of poplar grafting, and in particular to a grafting device and a grafting method which are beneficial to the development of ear and ripening of seeds on short branches of poplars. Background Art

[0002] Poplar grafting is an effective method for breeding and improving poplar varieties. In actual work, flower branches are often collected from large trees in advance, cultivated using indoor hydroponic methods, and then artificially pollinated. However, the maturity and fullness of the seeds are also affected by the development of the fruit, which greatly reduces the seed germination rate. Based on the previous method, we found through practice that the method of grafting short flower branches carrying fruit spikes can be used to improve this work. The main method is to wait for the fruit spikes to be obtained through hybridization, and then graft the fruit spikes together with a small section of flower branches onto young trees (1-2 year old strong young trees, which can ensure that the young trees provide nutrition for the fruit spikes and ensure that there are more plants on a small area of ​​land). Before grafting, the young trees are cut off and the height of about 50cm is retained (it should be adjustable, and we use about this height). It can be seen that these fruit spikes and fruits are obviously growing very well. Practice has proved that the number of seeds and germination rate are also very ideal, which significantly improves the hybridization effect.

[0003] After the short flower branches are grafted onto the young trees, they usually need to be fixed in a winding manner. As the short flower branches grow, they gradually tilt and become heavier, and are affected by wind and other factors, they need to be fixed more tightly and rigidly. However, it is difficult to control the strength of rigid fixation, and there is a risk of short branches or young trees breaking under long-term rigid fixation. Therefore, we propose a grafting device and a grafting method that are beneficial to the development of fruit clusters and seed maturation on short branches of poplars. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a grafting device and a grafting method which are beneficial to the development of ear and seed maturation on short branches of poplar, comprising:

[0005] A connecting long rod, which is used to connectively support and fix the grafting device as a whole;

[0006] A flexible pressing mechanism is used for performing flexible pressing and auxiliary fixation of short branches at the grafting position of saplings to prevent the risk of short branches or saplings being broken due to the difficulty in controlling the strength of rigid fixation for a long time. A long screw is provided on one side of the flexible pressing mechanism;

The bottom of the flexible pressing mechanism is fixedly connected to the top of the connecting long rod, and the bottom of the connecting long rod is fixedly connected to the inner side of the stabilizing mechanism.

[0009] Wherein, the flexible pressing mechanism comprises:

[0010] A square sponge block is used for performing flexible press-attachment auxiliary fixation on the short branches at the grafting position of the sapling. When the square splint continues to move, the square sponge block is squeezed to perform flexible press-attachment auxiliary fixation on the grafting position of the short flower branch on the sapling, so as to prevent the risk of short branches or saplings being broken due to the difficulty in controlling the force of rigid fixation for a long time. A square sponge is provided on one side of the square sponge block;

[0011] One side of the square clamp is fixedly connected to one side of the square sponge block;

[0012] The bottom of the square clamp is fixedly connected to the top of the connecting long rod, and the square clamp is sleeved on the long screw and threadedly connected to the long screw;

[0013] A side-opened circular hole is opened on one side of the square sponge block, and the inner wall of the side-opened circular hole is fixedly connected to a ventilation component, and a corrugated fixing strip is fixedly connected to the top of the square plywood, and the corrugated fixing strip is arranged on the square plywood to stabilize the shape of the corrugated arc piece of auxiliary support, so as to prevent the grafted short flower branches from becoming heavy after gradual growth, causing the corrugated arc piece to be difficult to bear the weight and be pressed down by the flower branches together, and the corrugated arc piece on the square plywood is fixedly connected to the shape of the corrugated arc piece of auxiliary support, so as to prevent the grafted short flower branches from becoming heavy after gradual growth, causing the corrugated arc piece to be difficult to bear the weight and be pressed down by the flower branches together, and the corrugated arc piece on the square plywood surrounds and assists in supporting the grafted short flower branches with the sapling as the center, so as to prevent the short flower branches just grafted on the sapling from being deformed, bent, and broken due to the influence of wind and sand, etc., and affecting their growth. The outer surface of the corrugated arc piece is opened with a corrugated surface concave hole, and the corrugated surface concave hole is arranged on the corrugated surface of the corrugated arc piece to facilitate the passage of air, so as to prevent the air from being difficult to circulate in the area surrounded and covered by the corrugated arc piece and blocking the sunlight, affecting the growth effect of the short branches;

[0014] There are multiple wave-shaped fixing strips, and the multiple wave-shaped fixing strips are distributed on the square clamping plate. There are multiple wave-shaped concave holes, and the multiple wave-shaped concave holes are distributed on the wave-shaped arc sheet.

[0015] Furthermore, the ventilation component includes an annular tube, an outer surface of which is provided with large air holes, and the small air holes provided on the annular push plate cooperate with the slow movement of the annular push plate to fill the air between the annular push plate and the cross sleeve block, while reducing the suction effect of the air inside the square sponge block, thereby preventing the gas entering the square sponge block from being sucked into the annular tube again before it is completely dissipated, making it difficult to achieve the ventilation effect. The inner wall of the annular tube is fixedly connected with a cross sleeve block, and the inner wall of the cross sleeve block is fixedly connected with a two-way electric telescopic rod, and both ends of the two-way electric telescopic rod are fixedly connected with a cross joint plate, and a side joint rod is fixedly connected with a side joint rod on a side of the cross joint plate close to the two-way electric telescopic rod, and an annular push plate is fixedly connected with an end of the side joint rod away from the cross joint plate, and the gas is pushed from the large air holes into the square sponge block through the annular push plate to be dissipated toward the grafting position to ensure air circulation at the grafting position, thereby preventing the short flower branches on the sapling from being sucked in when the flexible press-attached auxiliary fixation is performed on the grafting position. The large-area coverage of the end area of ​​the nutrients leads to poor air permeability, which affects the growth of short branches. The annular push plate scrapes and cleans the inner wall of the annular tube and the surface of the two-way electric telescopic rod when moving outward, so as to prevent excessive dust particles and debris from gradually accumulating in the annular tube after long-term use, which affects the gas circulation and use effect. The outer surface of the annular push plate is provided with small air holes. The effect of air leakage is slowed down by setting the aperture of the small air holes to be much smaller than the aperture of the large air holes and setting the position of the small air holes on the surface of the annular push plate away from the large air holes, so as to prevent the gas from leaking out through the small air holes in large quantities when the annular push plate pushes the gas between the annular tube and the two-way electric telescopic rod and being difficult to be pushed into the square sponge block.

[0016] Furthermore, the stabilizing mechanism comprises an arc-shaped bottom plate, the top of the arc-shaped bottom plate is provided with an arc-shaped top groove, the bottom of the inner wall of the arc-shaped top groove is provided with a circular through hole, the top of the inner wall of the circular through hole is provided with a threaded top hole, the inner wall of the threaded top hole is threadedly connected with a threaded rod, the top of the threaded rod is fixedly connected with a rounded twist block, the bottom of the rounded twist block is fixedly connected with a spiral thorn bar, the spiral thorn bar penetrates into the soil and embeds into the soil when it moves downward in a spiral, so that the arc-shaped bottom plate and the soil are integrally connected and fixed, preventing the arc-shaped bottom plate from being hit by foreign objects and causing the grafting device to topple or shift when the wind force is too strong, and the soil adhered to the outer surface of the spiral thorn bar, which is in contact with the inner wall of the circular through hole, is scraped off together when it moves upward, preventing the spiral thorn bar from gradually accumulating too much clay on the surface after long-term use, affecting the subsequent embedding effect of the spiral thorn bar in the soil. The bottom of the threaded rod is rotatably connected to a trapezoidal round block by a rotating bolt. When the trapezoidal round block moves downward, the space at the bottom of the trapezoidal round block at the circular through hole is gradually reduced to prevent the internal area of ​​the circular through hole from gradually accumulating too much mud after long-term use and filling it up, causing blockage and difficulty in use. The outer surface of the trapezoidal round block is fixedly connected to a corrugated ring piece. When the corrugated ring piece is stretched or contracted, it always wraps and protects the threaded rod to prevent the mud in the circular through hole from seeping into the trapezoidal round block and attaching to the threaded rod to affect its thread fit. The inner side of the arc bottom plate is fixedly connected to the bottom of the connecting long rod, and a plurality of arc top grooves are provided, and a plurality of the arc top grooves are distributed on the top of the arc bottom plate. The top of the corrugated ring piece is fixedly connected to the top of the inner wall of the circular through hole, and the corrugated ring piece is arranged at a position where the outer surface of the trapezoidal round block is located outside the threaded rod.

[0020] S3: Flexible auxiliary fixation of short branches, two flexible pressing mechanisms are placed on both sides of the sapling and the long screw is passed through the two flexible pressing mechanisms in sequence by threaded matching. The long screw is rotated to make the two flexible pressing mechanisms continuously approach the short branches on the sapling and perform flexible pressing auxiliary fixation on them;

[0021] S4: The air at the grafting site of the short branch is unblocked, and the air exchange component in the flexible pressing mechanism is used to continuously ventilate the grafting site of the short branch to maintain air unblocking;

[0022] S5: Ground stable support. After the grafting is completed, the stabilizing mechanism provides stable support for the bottom of the adjusted grafting device by embedding it into the soil.

[0023] The present invention has the beneficial effects:

[0024] 1. When the square splint of the present invention continues to move, the square sponge block is squeezed to perform flexible press-attachment auxiliary fixation on the grafting position of the short flower branch on the sapling, so as to prevent the risk of short branches or saplings being broken due to long-term rigid fixation due to difficulty in controlling the force of rigid fixation. The annular push plate pushes the gas from the large air holes into the square sponge block and releases it to the grafting position to ensure air circulation at the grafting position, so as to prevent the end area of ​​the short flower branch that absorbs nutrients from being covered over a large area when the grafting position of the short flower branch on the sapling is fixed with flexible press-attachment auxiliary fixation, resulting in poor air permeability and affecting the growth of the short branch. When the spiral thorn strips move downward in a spiral, they penetrate into the soil and are embedded in the soil, so that the arc bottom plate is connected and fixed to the soil in an integrated manner, so as to prevent the arc bottom plate from being hit by foreign objects and causing the grafting device to fall or deviate when the wind is too strong.

[0025] 2. The present invention provides a flexible pressing mechanism. When the square plywood continues to move, the square sponge block is squeezed to perform flexible pressing and auxiliary fixation on the grafting position of the short flower branches on the sapling, thereby preventing the risk of short branches or saplings being broken due to long-term rigid fixation caused by the difficulty in controlling the force due to rigid fixation. The corrugated arc pieces on the square plywood surround and assist in supporting the grafted short flower branches with the sapling as the center, thereby preventing the short flower branches just grafted on the sapling from being deformed and bent and broken due to the influence of wind and sand, etc., affecting their growth. Corrugated fixing strips are provided on the square plywood to stabilize the shape of the corrugated arc pieces for auxiliary support, thereby preventing the grafted short flower branches from gradually growing and becoming heavy, thereby preventing the corrugated arc pieces from being difficult to bear the weight and being pressed down by the flower branches. Corrugated surface concave holes are provided on the wave surface of the corrugated arc pieces to facilitate air passage, thereby preventing the air from being difficult to circulate in the area surrounded and covered by the corrugated arc pieces, thereby blocking the sunlight and affecting the growth effect of the short branches.

[0026] 3. The present invention provides a ventilation component, and the annular push plate pushes the gas from the large air holes to the square sponge block to be released to the grafting position to ensure air circulation at the grafting position, so as to prevent the end area of ​​the short flower branch absorbing nutrients from being covered over a large area when the short flower branch on the sapling is fixed by flexible press-attachment auxiliary fixation, resulting in poor ventilation effect and affecting the growth of the short branch. When the annular push plate moves outward, it scrapes and cleans the inner wall of the annular tube and the surface of the two-way electric telescopic rod to prevent excessive dust particles and debris from gradually accumulating in the annular tube after long-term use and affecting the air circulation and use effect. The small air holes are coordinated with the slow movement of the annular push plate to fill the air between the annular push plate and the cross sleeve block, while reducing the suction effect of the air inside the square sponge block, preventing the gas entering the square sponge block from being sucked into the annular tube again before it is completely dissipated, making it difficult to achieve a ventilation effect. The effect of air leakage is slowed down by setting the aperture of the small air holes to be much smaller than the aperture of the large air holes and setting the position on the surface of the annular push plate away from the large air holes, preventing the annular push plate from leaking a large amount of gas through the small air holes when pushing the gas between the annular tube and the two-way electric telescopic rod, making it difficult to be pushed into the square sponge block.

[0027] 4. The present invention provides a stabilizing mechanism, and the spiral barbs penetrate into the soil and embed into the soil when they move downward in a spiral, so that the arc bottom plate is integrally connected and fixed to the soil, preventing the arc bottom plate from being hit by foreign objects and causing the grafting device to tip over or shift when the wind is too strong. When the trapezoidal block moves downward, the space of the circular through hole at the bottom of the trapezoidal block is gradually reduced, preventing the internal area of ​​the circular through hole from gradually accumulating too much soil after long-term use, filling it up and causing blockage and making it difficult to use. When the corrugated ring piece is extended or contracted, the threaded rod is always wrapped and protected, preventing the mud and ash in the circular through hole from seeping into the top of the trapezoidal block and attaching to the threaded rod, affecting its thread fit. When the spiral bar that is always in contact with the inner wall of the circular through hole moves upward, the soil adhered to the outer surface is scraped off together, preventing the spiral bar from gradually accumulating too much clay on the surface after long-term use, affecting the effect of subsequent embedding in the soil.

[0052] The stabilizing mechanism 4 includes an arc-shaped bottom plate 401, an arc-shaped top groove 402 is provided at the top of the arc-shaped bottom plate 401, a circular through hole 403 is provided at the bottom of the inner wall of the arc-shaped top groove 402, a threaded top hole 404 is provided at the top of the inner wall of the circular through hole 403, a threaded rod 405 is threadedly connected to the inner wall of the threaded top hole 404, a rounded twist block 406 is fixedly connected to the top of the threaded rod 405, a spiral barb 407 is fixedly connected to the bottom of the rounded twist block 406, a trapezoidal round block 408 is rotatably connected to the bottom of the threaded rod 405 through a rotating bolt, a corrugated ring piece 409 is fixedly connected to the outer surface of the trapezoidal round block 408, the inner side of the arc-shaped bottom plate 401 is fixedly connected to the bottom of the connecting rod 1, and a plurality of arc-shaped top grooves 402 are provided, and A plurality of arc-shaped top grooves 402 are distributed on the top of the arc-shaped bottom plate 401, and the top of the corrugated ring piece 409 is fixedly connected to the top of the inner wall of the circular through hole 403, and the corrugated ring piece 409 is arranged on the outer surface of the trapezoidal round block 408 at a position outside the threaded rod 405. When in use, when it is necessary to dredge the air at the position where the short branches of the sapling are grafted, the cross-joint plate 2045 is driven to move toward the direction of the annular tube 2041 through the two-way electric telescopic rod 2044, and when the cross-joint plate 2045 moves, the annular push plate 2047 is driven to move together through the side connecting rod 2046, and when the annular push plate 2047 moves to between the inner wall of the annular tube 2041 and the two-way electric telescopic rod 2044, the internal gas is pushed, and the annular tube 2041 and the two-way electric When the gas between the telescopic rods 2044 is pushed, it enters the square sponge block 201 through the large air holes 2042 on the outer surface of the annular tube 2041 and then radiates from the square sponge block 201 to the outside.

When the spiral rod moves downward, it drives the bottom The trapezoidal round block 408 moves down together, and the space of the circular through hole 403 at the bottom of the trapezoidal round block 408 is gradually reduced when the trapezoidal round block 408 moves down. When the trapezoidal round block 408 moves down, it pulls the top corrugated ring piece 409 to stretch, and the spiral bar 407 of the trapezoidal round block 408 is driven to move up together by reversing the threaded rod 405 through the rounded torsion block 406. When the trapezoidal round block 408 moves up, it pushes the top corrugated ring piece 409 to shrink in corrugation. When the corrugated ring piece 409 stretches or shrinks, it always wraps and protects the threaded rod 405. When the spiral bar 407 moves up, the outer side is always in contact with the inner wall of the circular through hole 403. When the spiral bar 407 that is always in contact with the inner wall of the circular through hole 403 moves up, the soil adhering to the outer surface is scraped off together.

[0059] When the present invention is used, before grafting, the trunk of the sapling is first cut and a height of about 50 cm is retained for grafting, and then the short flower branches carrying the fruit ears are grafted onto the sapling and subjected to a winding pre-fixation treatment. After the treatment is completed, two flexible pressing and attaching mechanisms 2 are placed on both sides of the sapling and the long screw 3 is passed through the two flexible pressing and attaching mechanisms 2 in sequence by means of threaded cooperation. The long screw 3 is rotated to make the two flexible pressing and attaching mechanisms 2 constantly approach the short branches on the sapling and perform flexible pressing and attaching auxiliary fixation. The ventilation component 204 in the flexible pressing and attaching mechanism 2 is used to continuously ventilate the grafting position of the short branches to keep the air unobstructed. After the grafting is completed, the stabilizing mechanism 4 is embedded in the soil to provide a stable support to the bottom of the adjusted grafting device. The movable long screw rod 3 drives the two square clamps 202 to approach the grafting position of the short flower branches on the sapling. When the square clamp 202 moves, it drives the square sponge block 201 on one side and the corrugated fixing strip 205 on the top to move together. When the square sponge block 201 gradually approaches the sapling, it contacts the short flower branches on the sapling. When the square clamp 202 continues to move, the square sponge block 201 is squeezed to perform flexible press-attachment auxiliary fixation on the grafting position of the short flower branches on the sapling. The corrugated arc piece 206 on the square clamp 202 surrounds and assists in supporting the grafted short flower branches with the sapling as the center. The corrugated fixing strip 205 is provided on the square clamp 202 to stabilize the shape of the corrugated arc piece 206 for auxiliary support. The concave hole 207 is used to facilitate the passage of air. When it is necessary to dredge the air at the position where the short branches of the sapling are grafted, the cross joint 2045 is driven to move toward the direction of the annular tube 2041 through the two-way electric telescopic rod 2044. When the cross joint 2045 moves, the side connecting rod 2046 drives the annular push plate 2047 to move together. When the annular push plate 2047 moves to between the inner wall of the annular tube 2041 and the two-way electric telescopic rod 2044, the internal gas is pushed. When the gas between the annular tube 2041 and the two-way electric telescopic rod 2044 is pushed, it enters the square sponge block 201 through the large air hole 2042 on the outer surface of the annular tube 2041 and then radiates from the square sponge block 201 to the outside, and the gas is pushed from the large air hole 2042 to the square sponge block 201 through the annular push plate 2047. The air is released from the shaped sponge block 201 to the grafting position to ensure the air circulation at the grafting position. After the air is unblocked, the cross joint 2045 is driven by the two-way electric telescopic rod 2044 to move toward the outside of the annular tube 2041. When the cross joint 2045 moves, it drives the annular push plate 2047 to move together through the side connecting rod 2046. When the annular push plate 2047 moves, the outer side is always in contact with the inner wall of the annular tube 2041, and the inner side is always in contact with the outer surface of the two-way electric telescopic rod 2044. When the annular push plate 2047 moves toward the outside, it scrapes and cleans the inner wall of the annular tube 2041 and the surface of the two-way electric telescopic rod 2044. When the annular push plate 2047 moves toward the outside of the annular tube 2041, its moving speed is controlled very slowly by the two-way electric telescopic rod 2044.At the same time, small air holes 2048 are opened on the annular push plate 2047 to gradually fill the air in the area between the annular push plate 2047 and the cross sleeve block 2043. The small air holes 2048 opened on the annular push plate 2047 cooperate with the slow movement of the annular push plate 2047 to fill the air between the annular push plate 2047 and the cross sleeve block 2043, while reducing the suction effect of the air inside the square sponge block 201. The aperture of the small air hole 2048 is set to be much smaller than the aperture of the large hole 2042 and the position is set at a position on the surface of the annular push plate 2047 away from the large hole 2042 to slow down the leakage effect. After the flexible pressing mechanism 2 is fixed, the rounded twist block 406 is twisted to drive the threaded rod 405 and the spiral barb 407 at the bottom to rotate together. When the threaded rod 405 rotates, it cooperates with the thread of the threaded top hole 404 to rotate downward. At the same time, when the threaded rod 405 rotates downward, the rounded twist block 406 drives the spiral barb When the spiral bar 407 moves downward, it penetrates into the soil and embeds into the soil, so that the arc bottom plate 401 is integrally connected and fixed to the soil. When the spiral rod moves downward, it drives the trapezoidal round block 408 at the bottom to move downward together. When the trapezoidal round block 408 moves downward, the space at the bottom of the circular through hole 403 at the bottom of the trapezoidal round block 408 is gradually reduced. When the trapezoidal round block 408 moves downward, it pulls the corrugated ring piece 409 at the top to stretch, and the rounded torsion block 406 is used to tighten the rounded torsion block 406. The reverse threaded rod 405 drives the trapezoidal round block 408 and the spiral bar 407 to move upward together. When the trapezoidal round block 408 moves upward, it pushes the corrugated ring piece 409 on the top to shrink in corrugated form. When the corrugated ring piece 409 stretches or shrinks, it always wraps and protects the threaded rod 405. When the spiral bar 407 moves upward, the outer side is always in contact with the inner wall of the circular through hole 403. When the spiral bar 407 that is always in contact with the inner wall of the circular through hole 403 moves upward, the dirt adhering to the outer surface is scraped away together.
