Description

Technical Field

[0001] This invention relates to the field of Cornus officinalis cultivation technology. Specifically, it relates to an efficient method for propagating Cornus officinalis by cuttings. Background Technology

[0002] Cuttings are also a common method of plant propagation. Stems, leaves, roots, buds, etc., of a plant can be cut and inserted into soil, sand, or soaked in water. Once roots have developed, they can be planted to become independent new plants. There are various methods of cuttings, including upright cuttings, horizontal cuttings, and oblique cuttings.

[0003] In some cutting propagation methods, after multiple seedlings have grown on the cutting, a cutting tool is used to cut the cutting so that the seedlings can grow into individual plants, thereby achieving efficient propagation. However, the cutting tools in the current technology cannot guarantee that the cut area is minimized. If the cut area is too large, the cut will be difficult to heal, or even rot, which will affect the plant growth. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to provide a method for efficient cutting propagation of Cornus officinalis with minimal cut area.

[0008] Step C: Bend the cutting into an L-shape, keeping the length of section A between 14-18cm; secure the cutting with an elastic rope, tying one end of the rope to section A and the other end to section B, ensuring the distance from the bend point to both ends of the rope is 4-6cm; bury section B horizontally in the seedbed, keeping the depth of insertion 6-8cm, and ensuring section A extends 7-10cm beyond the seedbed, with 2-3 buds on both sections A and B;

[0009] Step D: Tamp down the soil around the cuttings and water the seedbed;

[0010] Step E: After the seedlings grow on the cuttings buried in the soil and extend 20cm out of the soil, use a cutting device to cut the cuttings so that each seedling can grow into a plant.

Detailed Implementation

[0036] The efficient cutting propagation technique for Cornus officinalis described in this embodiment can be found in [reference needed]. Figure 1 This includes the following steps:

[0037] Step A: In mid-May, cut healthy branches with 4-6 tender buds, cut off both ends and apply plant disinfectant to the cut. The plant disinfectant is chlorothalonil, which can reduce the possibility of rotting at the cut. After cutting, the length of the branch should be controlled between 30-36cm.

[0038] Step B: Soak the cuttings in rooting hormone solution for 1-1.5 hours. The rooting hormone solution is an indoleacetic acid solution, which can promote rooting and healing at the cut, thereby improving the survival rate of the cuttings.

[0039] Step C: Bend the cutting into an L-shape, keeping the length of section A between 14-18cm; secure the cutting with an elastic rope, tying one end of the rope to section A and the other end to section B, ensuring the distance from the bend point to both ends of the rope is 4-6cm; bury section B horizontally in the seedbed, keeping the depth of insertion 6-8cm, and ensuring section A extends 7-10cm beyond the seedbed, with 2-3 buds on both sections A and B;

[0040] Step D: Tamp down the soil around the cuttings and water the seedbed;

[0041] Step E: After the seedlings grow from the cuttings buried in the soil and extend 20cm out of the soil, use a cutting device to cut the cuttings so that each seedling can grow into a separate plant, which improves the efficiency of cutting propagation. In March of the following year, the seedlings and cuttings are transplanted to their final location.

[0042] like Figure 2 , Figure 7 and Figure 8 As shown, the cutting device includes a push block 1 that can move horizontally along the surface of the seedbed. A support frame 2 is rotatably connected to the push block 1. Two first cutters 3 are mounted on the bottom of the support frame 2, and a second cutter 4 matching the first cutters 3 is rotatably connected to the support frame 2. A bark-cutting mechanism 5 and a locking mechanism 6 are mounted on the first cutters 3. The drive part of the bark-cutting mechanism 5 is driven to the locking mechanism 6. When it is necessary to cut the cutting, the push block 1 moves horizontally along the surface of the seedbed, driving the first cutters 3 to approach the cutting. One of the first cutters 3 touches the cutting. When the cutting is touched, the support frame 2 rotates, causing the other first cutter 3 to rotate and move forward until it touches the cutting. At this time, the blade of the first cutter 3 is perpendicular to the direction of the cutting, thus minimizing the cut area. During the cutting process of the first cutter 3, the bark-cutting mechanism 5 will first cut off part of the bark of the cutting to avoid the heartwood from separating from the bark in large quantities due to pressure during the cutting process, thereby increasing the wound area. In addition, during the cutting process, the device has a fixed clamping force on the surface of the cutting, reducing the possibility of the bark tearing due to pressure deformation of the cutting, which would increase the wound area.

[0043] like Figure 8 and Figure 9As shown, the peeling mechanism 5 includes a guide rod 501. A mounting groove 509 is provided on the first cutter 3, and a mounting hole is provided on the inner wall of the mounting groove 509. The guide rod 501 is longitudinally positioned within the mounting groove 509, and can be inserted into and rotated within the mounting hole. Two or more mounting shells 502 are slidably connected to the guide rod 501. A sleeve 503 is provided on one side of each mounting shell 502, and hydraulic oil is stored inside the sleeve 503. The mounting shells 502 and the sleeve 503 communicate internally. A first piston 504 is slidably and sealingly fitted inside the sleeve 503. A first rack 505 is provided on the side of the first piston 504 closest to the mounting shell 502, and a first piston 505 is provided on the other side of the first piston 504. The piston rod 506 has a circular cutter 507 fixedly connected to the other end of the sleeve 503. A guide wheel 508 is coaxially rotatably connected to the circular cutter 507. An elastic block 510 is provided between the sleeves 503. An elastic sealing layer 511 is provided in the mounting groove 509. The outer surface of the sleeve 503 is fixedly connected to the elastic sealing layer 511. The elastic sealing layer 511 prevents impurities such as soil and dust from entering the mounting groove 509. As the first cutter 3 approaches the insert, the circular cutter 507 first inserts into the surface of the insert, and the guide wheel 508 presses against the surface of the insert. As the pressure acting on the insert gradually increases, the first piston rod 506 gradually retracts into the sleeve 503.

[0044] like Figure 8 , Figure 9 and Figure 10As shown, the locking mechanism 6 includes a sleeve 601 rotatably connected to the mounting housing 502, a guide rod 501 passing through the sleeve 601 and sliding within the sleeve 601, a gear 602 coaxially connected to the sleeve 601 located within the mounting housing 502, and a first rack 505 meshing with the gear 602; a drainage channel 603 is provided inside the mounting housing 502, the sleeve 503 is in fluid communication with the drainage channel 603, a valve disc 604 is provided on the sleeve 601, the edge of the valve disc 604 is sealed against the inner wall of the drainage channel 603; an elastic bladder 605 is installed inside the mounting housing 502, the input end of the elastic bladder 605 is in fluid communication with the output end of the drainage channel 603; a first positioning key 606 is fixedly connected to the guide rod 501, a first keyway is provided on the inner wall of the sleeve 601, and the outer surface of the first positioning key 606 slides against the inner wall of the first keyway. During the process of the first piston rod 506 retracting into the sleeve 503, the hydraulic oil in the sleeve 503 flows into the elastic bladder 605 through the drain channel 603, and the elastic bladder 605 expands. When one of the first piston rods 506 is fully retracted into the sleeve 503, the first rack 505 triggers the gear 602 to rotate, and the sleeve 601 drives the guide rod 501 to rotate all the sleeves 601 at the same time. The sleeve 601 drives the valve disc 604 to close the drain channel 603, so that the hydraulic oil can no longer flow into the elastic bladder 605. Even if all the first piston rods 506 can no longer be retracted into the sleeve 503, the position of the guide wheel 508 is limited. In conjunction with the elastic block 510, the guide wheel 508 has a certain clamping force on the insert, so that when the insert is cut off, the insert is not deformed or the deformation is small due to the clamping force of multiple guide wheels 508, thereby reducing the wound area.

[0045] like Figure 7 As shown, a piston cylinder 7 is fixedly connected to the support frame 2. A second piston 8 is slidably sealed inside the piston cylinder 7. A second piston rod 9 is provided at the bottom of the second piston 8. The other end of the second piston rod 9 extends out of the piston cylinder 7, and a drive tooth 10 is provided on the second piston rod 9 extending out of the piston cylinder 7. A first spring 13 is installed inside the piston cylinder 7 above the second piston 8. A first air supply pipe 11 is provided at the top of the piston cylinder 7, and a second air supply pipe 12 is provided at the bottom of the piston cylinder 7. A connecting shaft 58 is rotatably connected to the inner wall of the support frame 2. The connecting shaft 58 is fixedly connected to the second cutter 4, and one end of the connecting shaft 58 is coaxially connected to... A drive wheel 14 is connected, and a drive gear 10 meshes with the drive wheel 14. Each of the two second cutters 4 has an arc-shaped protrusion 15 on one side that is close to each other. When air is supplied to the piston cylinder 7 through the second air supply pipe 12, the second piston 8 moves upward with the second piston rod 9. The drive gear 10 drives the drive wheel 14 to rotate, which causes the connecting shaft 58 to drive the second cutter 4 to rotate and approach the first cutter 3, thereby cutting off the insert. The rotation angle of the second cutter 4 is 180 degrees. After the insert is cut off, the arc-shaped protrusion 15 can push out the cut-off section to prevent the cut-off section from not being removed and being reconnected to the insert.

[0046] like Figure 2 and Figure 4 As shown, the cutting device also includes a mounting block 16, on which a first air cylinder 17 and a slide rail 18 are mounted. The first air cylinder 17 and the slide rail 18 are arranged in parallel. A third piston 19 is slidably sealed inside the first air cylinder 17, and a third piston rod 20 is provided on one side of the third piston 19. A locking block is provided on the pushing block 1, which is locked into the slide rail 18 and can slide within the slide rail 18. The slide rail 18 has two or more positioning holes 60. A first sliding groove 21 is provided on the pushing block 1, and a slider 22 is slidably connected within the first sliding groove 21. The other end of the third piston rod 20 extends out of the end of the first air cylinder 17 and is inserted into the pushing block 1. It is fixedly connected to the slider 22. A second spring 23 is installed in the first groove 21 on the side of the slider 22 away from the third piston rod 20. A fourth air supply pipe 29 is provided at the end of the first air cylinder 17 away from the push block 1. A fourth spring 30 is sleeved on the third piston rod 20 located in the first air cylinder 17. A pressure relief valve 31 is provided at the end of the outer surface of the first air cylinder 17 away from the push block 1. The output end of the pressure relief valve 31 is in fluid communication with the input end of the second air supply pipe 12. When air is supplied to the first air cylinder 17 through the fourth air supply pipe 29, the third piston rod 20 extends out of the first air cylinder 17, causing the push block 1 to move laterally.

[0047] like Figure 4 and Figure 5 As shown, the push block 1 has a limiting hole 59 that matches the positioning insertion hole 60. The slider 22 has a guide groove 24, and a fourth piston 25 is slidably and sealingly fitted in the guide groove 24. One side of the fourth piston 25 has a pin 26 that matches the positioning insertion hole 60, and the other end of the pin 26 protrudes from the slider 22. A third spring 27 is fitted on the pin 26 located in the guide groove 24. A third air supply pipe 28 is provided on the side of the slider 22 that protrudes from the push block 1. The input end of the guide groove 24 is in fluid communication with the output end of the third air supply pipe 28. The push block 1 has a circular groove 3. 2. A rotating shaft 33 is provided on the support frame 2. The other end of the rotating shaft 33 is inserted into the circular groove 32, and the rotating shaft 33 can rotate along the axis of the circular groove 32. A spiral spring 34 is installed between the outer surface of the rotating shaft 33 and the inner wall of the circular groove 32. The spiral spring 34 provides the restoring force of the rotating shaft 33. During the movement of the pushing block 1, the first cutter 3 moves closer to the insert. When one of the first cutters 3 touches the insert, the support frame 2 rotates along the rotating shaft 33, causing the other first cutter 3 to rotate and move forward until it touches the insert. At this time, the blade of the first cutter 3 is perpendicular to the direction of the insert. Figure 5As shown, since the first cutter 3 is pressed against the cutting, the first cutter 3 stops moving when the push block 1 continues to move, causing the second spring 23 to be compressed. The slider 22 slides in the first groove 21. When the slider 22 slides until the pin 26 is aligned with the limiting hole 59, the high-pressure gas output from the third gas supply pipe 28 pushes the pin 26. The pin 26 passes through the limiting hole 59 and is inserted into the positioning hole 60, thereby limiting the position of the push block 1 and preventing the push block 1 from continuing to move, which would cause the rootstock on the cutting to detach from the soil or even break the cutting.

[0048] like Figure 2 and Figure 3 As shown, the cutting device also includes two support blocks 35. One support block 35 is fixedly connected to a guide post 36 and a fixing rod 37, with the guide post 36 and the fixing rod 37 arranged parallel to each other. The other end of the guide post 36 passes through the mounting block 16 and the other support block 35 in sequence, and both the mounting block 16 and the support block 35 are slidably connected to the guide post 36. A sixth spring 61 is sleeved on the guide post 36 between the mounting block 16 and the support block 35. A second rack 38 is provided at one end of the fixing rod 37 that passes through the mounting block 16. A second groove 39 is provided on the other support block 35, and the second rack 38 is inserted into the second groove 39 and can slide within the second groove 39. A third groove 40 is provided on one side of the second groove 39 within the support block 35, and a limit block 41 is slidably engaged within the third groove 40. One side of the 1 is set as an inclined surface, and the limiting block 41 is engaged with the tooth groove of the second rack 38; the limiting block 41 is provided with a pull rod 42 on the side away from the second rack 38, and the other end of the pull rod 42 passes through the end of the support block 35 and is fixedly connected to a fixing cap 43. A fifth spring 44 is installed between the support block 35 and the fixing cap 43. The fifth spring 44 is a traction spring; the bottom of the support block 35 is provided with an insert rod 45, and a second air cylinder 46 is slidably fitted on the insert rod 45. A sealing ring 47 is fixedly connected to the insert rod 45 located inside the second air cylinder 46. The inner wall of the second air cylinder 46 is slidably sealed with the edge of the sealing ring 47. Two push-type exhaust valves 62 are installed on the inner bottom wall of the second air cylinder 46. The input ends of the third air supply pipe 28 and the fourth air supply pipe 29 are respectively fluidly connected to the two push-type exhaust valves 62; Figure 2 and Figure 3As shown, pressing the support block 35 causes the insertion rod 45 to be inserted into the soil. During the downward movement of the insertion rod 45, the sealing ring 47 slides downward inside the second air cylinder 46, increasing the gas pressure below the sealing ring 47. When the sealing ring 47 reaches its limit, it presses against the button of the push-button exhaust valve 62, opening the push-button exhaust valve 62 to allow high-pressure gas to flow into the third air supply pipe 28 and the fourth air supply pipe 29. The insertion rod 45 is provided with a second positioning key 48, and the top of the second air cylinder 46 is provided with a second keyway 49. The outer surface of the second positioning key 48 slides in cooperation with the inner wall of the second keyway 49. The bottom end of the second air cylinder 46 is fixedly connected to a pointing rod 50. Adjusting the distance between the two pointing rods 50 and making the two pointing rods 50 point to two adjacent seedlings respectively, through the setting of the sixth spring 61, the mounting block 16 is located in the middle of the two seedlings, that is, the cutting position of the insertion rod is located in the middle of the two seedlings. When adjusting the distance between the two support blocks 35 (in the initial state, the distance between the two support blocks 35 is the largest), as Figure 6 As shown, the second rack 38 slides along the second groove 39, and the teeth of the second rack 38 abut against the inclined surface of the limiting block 41, causing the limiting block 41 to retract into the third groove 40. When the distance adjustment is completed, the fifth spring 44 pulls the fixing cap 43 to cause the limiting block 41 to extend out of the third groove 40, and the limiting block 41 is embedded in the tooth groove of the second rack 38, thereby limiting the position of the second rack 38, that is, limiting the position of the support block 35. After the device is used, the fixing cap 43 is pulled to cause the limiting block 41 to retract into the third groove 40, and the sixth spring 61 releases its force to drive the two support blocks 35 away from each other to reset.

[0049] The working steps of the device in this invention are as follows:

[0050] 1. For example Figure 1 As shown, the positions of the two pointing rods 50 are adjusted according to the positions of two adjacent seedlings, so that the two pointing rods 50 point to the two adjacent seedlings respectively. Through the setting of the sixth spring 61, the mounting block 16 is positioned in the middle of the two seedlings, that is, the first cutter 3 is aligned with the middle of the cutting. Figure 3 As shown, pressing the support block 35 causes the insertion rod 45 to be inserted into the soil layer, the first cutter 3 is inserted into the soil layer, and during the downward movement of the insertion rod 45, the sealing ring 47 moves down and increases the gas pressure below the sealing ring 47. When the sealing ring 47 moves down to the limit, it hits the button of the press-type exhaust valve 62, and the press-type exhaust valve 62 opens to allow high-pressure gas to flow into the third gas pipeline 28 and the fourth gas pipeline 29.

[0051] 2. For example Figure 4 , Figure 5 and Figure 7As shown, when the fourth gas supply pipe 29 supplies gas into the first gas cylinder 17, the third piston rod 20 extends out of the first gas cylinder 17, pushing the block 1 to move the first cutter 3 closer to the insert. When one of the first cutters 3 touches the insert, the support frame 2 rotates along the rotating shaft 33, causing the other first cutter 3 to rotate and advance until it touches the insert. At this time, the blade direction of the first cutter 3 is perpendicular to the direction of the insert; as shown... Figure 4 and Figure 5 As shown, since the first cutter 3 is already against the cutting, the first cutter 3 stops moving when the push block 1 continues to move, causing the second spring 23 to be compressed. The slider 22 slides in the first groove 21. When the slider 22 slides until the pin 26 is aligned with the limiting hole 59, the third gas supply pipe 28 outputs high-pressure gas to push the pin 26. The pin 26 passes through the limiting hole 59 and is inserted into the positioning hole 60, thereby limiting the position of the push block 1 and preventing the push block 1 from continuing to move, thereby pushing the rootstock on the cutting to detach from the soil or even causing the cutting to break.

[0052] 3. For example Figure 4 and Figure 7 As shown, the high-pressure gas in the first gas cylinder 17 is supplied to the piston cylinder 7 through the second gas supply pipe 12. The second piston 8 moves upward with the second piston rod 9, and the drive gear 10 drives the drive wheel 14 to rotate, so that the connecting shaft 58 drives the second cutter 4 to rotate and move closer to the first cutter 3.

[0053] 4. For example Figure 8 As shown, the second cutter 4 presses against the insert and approaches the first cutter 3. The circular cutter 507 first inserts into the surface of the insert, and the guide wheel 508 presses against the surface of the insert. As the insert is pressed against the guide wheel 508, the first piston rod 506 gradually retracts into the sleeve 503.

[0054] 5. For example Figure 9 and Figure 10 As shown, when the first piston rod 506 retracts into the sleeve 503, the hydraulic oil in the sleeve 503 flows into the elastic bladder 605 through the drain channel 603, causing the elastic bladder 605 to expand. When one of the first piston rods 506 is fully retracted into the sleeve 503, the first rack 505 triggers the gear 602 to rotate, and the sleeve 601 drives the guide rod 501 to rotate all the sleeves 601 simultaneously. The sleeve 601 drives the valve disc 604 to close the drain channel 603, preventing hydraulic oil from flowing into the elastic bladder 605. Even if all the first piston rods 506 cannot retract into the sleeve 503, the position of the guide wheel 508 is limited. In conjunction with the elastic block 510, the guide wheel 508 has a certain clamping force on the cutting, so that when the cutting is cut, the cutting is not deformed or the deformation is small due to the clamping force of multiple guide wheels 508, thereby reducing the possibility of the cutting being deformed by pressure, causing the bark to tear and the wound area to increase.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
