Description

Technical Field

[0001] This invention relates to the field of Kentucky bluegrass propagation technology, specifically to a method for the asexual propagation and rejuvenation of Kentucky bluegrass. Background Technology

[0002] Kentucky bluegrass (Poa pratensis) is a rhizomatous grass species, cold-resistant and drought-tolerant, with rapid rhizomatous propagation. It is a typical community-building species on the Qinghai-Tibet Plateau and a core grass species used for ecological restoration. Kentucky bluegrass can reproduce through seeds or rhizomes. A key characteristic that distinguishes it from non-rhizomatous plants is that its clonal divisions undergo physiological integration at the junctions, arranging their growth pattern by altering the length of the spacers and the angle of branching to achieve optimal resource attraction and utilization, thus enabling resource sharing among the divisions. Kentucky bluegrass's asexual reproduction strategy is a product of its long-term adaptation to the harsh environment of the Qinghai-Tibet Plateau, and is not solely determined by natural biological processes; environmental factors strongly influence the plant's reproductive strategy.

[0003] In existing technologies, the asexual propagation and rejuvenation of Kentucky bluegrass generally adopts the method of stem division, that is, after the stems are divided, they are cultivated and then transplanted to the desired location.

[0004] In existing propagation bed transplanting technology, the seedlings are usually transplanted by digging them out. When digging them out, the roots need to retain soil. However, digging them out can easily cause the roots to break and the soil to be incomplete, failing to fully cover the roots, which leads to a decrease in the survival rate of Kentucky bluegrass. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a method for the asexual reproduction and rejuvenation of Kentucky bluegrass, which solves the problem that the digging method used in the asexual reproduction and rejuvenation of Kentucky bluegrass in the prior art easily leads to root breakage and incomplete soil coverage, resulting in a decrease in the survival rate of Kentucky bluegrass.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for the asexual propagation and rejuvenation of Kentucky bluegrass, comprising the following steps:

[0007] S1: Select Kentucky bluegrass that has been established for 3-4 years and has reduced production and degenerated, and manually divide the rhizomes of Kentucky bluegrass into several plants. Insert the rhizomes into a propagation bed with soil to maintain the condition of the transplanted roots.

[0008] S2: Insert the rhizomes into a propagation bed with soil to maintain the condition of the transplanted roots for at least one day, then cut and remove the bottom leaves, leaving the top leaves;

[0009] S3: When the seed is 1-2 months old, it mainly consumes its own nutrients to expand and increase the number of leaves. Apply a light fertilizer to the seed when it is 2-5 months old.

[0010] S4: Transplant Kentucky bluegrass before 5-6 months of age, retaining the soil around the roots and the roots intact during transplanting;

[0011] S5: Apply fertilizer 6-9 months after establishment to expand and increase the number of stems.

[0012] Furthermore, the propagation bed that can maintain the root condition of transplanted plants includes a bed body, on which boxes are arranged in a matrix; a tray is provided at the bottom of the box body, and an outer retaining plate is provided around the tray, with a gap between two adjacent outer retaining plates, and the space formed by the tray and the outer retaining plate is used to store soil; the bed body is provided with a drive mechanism that can drive the tray and the outer retaining plate to rise, so that the soil containing 5-6 month old Kentucky bluegrass can be lifted upwards from the box body.

[0013] Furthermore, the outer retaining plate includes a retaining plate body, which is arranged in a matrix around the perimeter of the pallet. The lower center of the retaining plate body is rotatably connected to the pallet via a pin. A force-bearing plate is provided on one lower side of the retaining plate body. The upper perimeter of the box body has a lifting head, which is perpendicular to the force-bearing plate. The side of the lifting head near the center of the box body protrudes from the inner surface of the force-bearing plate, so that the lifting head can push the force-bearing plate after the outer retaining plate rises with the pallet, causing the outer arc surface of the retaining plate body to open and detach from the soil.

[0014] Furthermore, the upper surface of the load-bearing plate is provided with a sloping top, and the side of the sloping top closer to the center of the tray is the higher end, and the side of the sloping top farther from the center of the tray is the lower end.

[0015] Furthermore, the upper surface of the tray is provided with a split bottom plate in the area opposite to the main body of the retaining plate, and multiple split bottom plates form a circular structure; a tension rope is connected between the upper surface of the split bottom plate and the opposite main body of the retaining plate, so that when the main body of the retaining plate is opened, the split bottom plate can be pulled to separate the split bottom plate from the soil bonding part.

[0016] Furthermore, a groove is formed in the radial direction of the upper surface of the tray, in the area opposite to the middle of the split base plate. A guide rod is installed in the groove, and a slider that can slide along the guide rod is provided in the groove. A spring is provided between the slider and the groove, and the slider is fixedly connected to the split base plate.

[0017] Furthermore, a rotating disk is rotatably mounted on the outer periphery of the upper surface of the tray, and an intermediate disk is rotatably mounted on the middle of the upper surface of the tray; a flexible mesh is provided between the intermediate disk and the rotating disk; a force-bearing block is fixedly provided on the outer side of the lower surface of the rotating disk, and a force-bearing groove is formed on the outer surface of the force-bearing block, and the force-bearing groove is a spiral groove with the center of the rotating disk as the center; a force-applying rod is fixedly provided on the inner wall of the box body in the area opposite to the force-bearing groove, so that when the tray moves upward, the force-applying rod can push the rotating disk to rotate, so that the rotating disk and the soil bonding position are separated from each other.

[0018] Furthermore, the outer periphery of the rotating disk is provided with a gear ring one, and the outer surface of the intermediate disk is also provided with a gear ring two. The gear ring one and the gear ring two mesh with each other so that the rotation of the rotating disk can drive the rotation of the intermediate disk.

[0019] Furthermore, the boxes arranged in a matrix are divided into a first group and a second group. The driving mechanism is used to drive the trays in the first and second groups to rise and fall asynchronously, so that the main bodies of the different groups of holding plates open alternately. The first group consists of non-adjacent boxes, and the second group consists of the remaining non-adjacent boxes. The driving mechanism includes: a short rod, which is fixed to the lower surface of the tray in the box that makes up the first group, and an upper support is fixed between the lower ends of multiple groups of short rods; a long rod, which is fixed to the lower surface of the tray in the box that makes up the second group, and a lower support is fixed between the lower ends of multiple groups of long rods; a first cam, which is located below the lower support; a second cam, which is located above the upper support; the protrusions of the first cam and the second cam form a 90° angle; a camshaft is fixed in the middle of both the first cam and the second cam, and the camshafts are connected by a belt drive structure; a drive motor for driving one of the camshafts is provided on the outer side of the bed.

[0020] Furthermore, a spraying mechanism is provided above one side of the bed; the spraying mechanism includes a side plate fixed above one side of the bed, a spraying pipe located above the side plate near the bed, and a nozzle fixed to the lower surface of the spraying pipe.

[0021] The present invention has the following beneficial effects:

[0022] (1) The asexual reproduction and rejuvenation method of Kentucky bluegrass involves setting up a propagation bed that can maintain the state of the transplanted roots, so that Kentucky bluegrass is transplanted by pushing out rather than digging out the roots. This method can avoid the roots of Kentucky bluegrass being broken, and can also ensure that all the soil is pushed out so that the soil completely covers the roots, thereby improving the survival rate of Kentucky bluegrass after transplanting.

[0023] (2) The asexual reproduction and rejuvenation method of this Kentucky bluegrass is equipped with an outer covering. When the soil is lifted out of the box, the area in contact with the outer covering can be wrapped. The soil in this area will not be lifted out of the outer covering, which greatly reduces the stress on the soil, thereby avoiding soil breakage and local detachment, and preventing the roots of Kentucky bluegrass from being exposed. In addition, the outer covering can also open on its own to detach from the soil. That is, the detachment of the outer surface of the soil is divided into two steps: the first step is to detach from the box, and the second step is to detach from the outer covering, thereby reducing the external force on the soil when it is detached and avoiding soil breakage.

[0024] (3) The asexual reproduction and rejuvenation method of this Kentucky bluegrass has a split bottom plate. When the main body of the plate gradually opens, it can pull the tension rope, so that the tension rope can pull the split bottom plate and the soil bonding part separates from each other. At this time, there are no bonding positions on the outer surface of the entire soil. The operator can manually remove the soil with Kentucky bluegrass from the tray.

[0025] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0044] The following is based on Figures 1-15 This invention describes a method for the asexual propagation and rejuvenation of Kentucky bluegrass.

[0045] Example 1: Please refer to Figures 1-13 As shown.

[0046] This invention provides a method for the asexual propagation and rejuvenation of Kentucky bluegrass, comprising the following steps:

[0047] S1: Select Kentucky bluegrass that has been established for 3-4 years and has experienced reduced production and degeneration. Manually divide the rhizomes of Kentucky bluegrass into several plants and insert the rhizomes into a propagation bed with soil to maintain the condition of the transplanted roots. Kentucky bluegrass that is 3-4 years old is considered old Kentucky bluegrass. Selecting this type of Kentucky bluegrass can extend the utilization period of Kentucky bluegrass.

[0048] S2: Insert the rhizomes into a propagation bed with soil to maintain the condition of the transplanted roots for at least one day, then cut and remove the bottom leaves, leaving the top leaves. Leaving the top leaves is to maintain the photosynthesis of Kentucky bluegrass.

[0049] S3: When the seed is 1-2 months old, it mainly consumes its own nutrients to expand and increase the number of leaves. Apply a light fertilizer to the seed when it is 2-5 months old.

[0050] S4: Transplant Kentucky bluegrass before 5-6 months of age, retaining the soil around the roots and the roots intact during transplanting;

[0051] S5: Apply fertilizer 6-9 months after establishment to expand and increase the number of stems.

[0052] like Figures 2-3 As shown, the propagation bed mentioned in S1 that can maintain the state of transplanted roots includes a bed body 2, which is a rectangular frame with an internal cavity, and boxes 3 are arranged in a matrix on the bed body 2, which serve as the growth place for Kentucky bluegrass.

[0053] Preferably, the length, width, and height of the bed 2 are 1.5m * 1m * 0.8m.

[0054] Combination Figures 4-8 As shown, a tray 71 is provided at the bottom of the box 3, and an outer retaining plate 5 is provided around the tray 71. There is a gap between two adjacent outer retaining plates 5. The space formed by the tray 71 and the outer retaining plate 5 is used to store soil. When the root diameter of the Kentucky bluegrass is inserted into the propagation bed with soil to maintain the transplanted root condition, it is actually inserted into the soil in the space formed by the tray 71 and the outer retaining plate 5. A drive mechanism 21 is provided in the bed 2 to drive the tray 71 and the outer retaining plate 5 to rise, so that the soil with 5-6 month old Kentucky bluegrass is lifted upward and detached from the box 3. When the Kentucky bluegrass and the soil it carries are lifted upward and detached from the box 3, the entire soil is exposed above the box 3, so that the operator can easily remove the entire soil. Compared with the existing technology of digging out the soil, the root system can be avoided.

[0055] It should be noted that if the outer retaining plate 5 is not installed, the tray 71 will push the soil directly upwards. This will cause all parts of the outer surface of the soil to detach from each other simultaneously with the box 3, resulting in huge external forces on the soil. Once the soil becomes soft, it will cause the clumps of soil to break and fall off locally, resulting in the roots being exposed.

[0056] Conversely, when the outer retaining plate 5 is set, the area in contact between the soil and the outer retaining plate 5 when the soil detaches upward from the box 3 can be wrapped. The soil in this area will not detach from the outer retaining plate 5, which greatly reduces the stress on the soil, thereby avoiding soil breakage and local detachment, and preventing the roots of Kentucky bluegrass from being exposed.

[0057] Combination Figure 5 , Figures 9-12 As shown, in this embodiment, after the soil detaches from the box 3, the outer retaining plate 5 automatically detaches from the soil. Specifically, the outer retaining plate 5 includes a retaining plate body 51, which is arranged in a matrix around the tray 71. The lower middle part of the retaining plate body 51 is rotatably connected to the tray 71 via a pin 53. A force-bearing plate 52 is provided on one lower side of the retaining plate body 51. A lifting head 4 is provided on the upper periphery of the box 3. The lifting head 4 is perpendicular to the force-bearing plate 52, and the side of the lifting head 4 closest to the center of the box 3 protrudes from the inner surface of the force-bearing plate 52, so that after the outer retaining plate 5 rises with the tray 71, the lifting head 4 can push the force-bearing plate 52, causing the outer arc surface of the retaining plate body 51 to open and detach from the soil.

[0058] In this embodiment, the outer retaining plate 5 moves upward with the tray 71 until the force plate 52 reaches the position of the lifting head 4. At this time, the lifting head 4 can push the force plate 52, thereby causing the outer retaining plate 5 to rotate along the pin 53, thus opening the retaining plate body 51 and separating it from the outer surface of the soil (see reference). Figure 11 and Figure 12 (As shown).

[0059] In summary, the present invention divides the detachment of the outer surface of the soil into two steps: the first step is to detach it from the box 3, and the second step is to detach it from the outer retaining plate 5, thereby reducing the external force on the soil during detachment and preventing soil breakage.

[0060] Preferably, a clamp 42 is fixed on the upper outer surface of the box body 3, and a fixing ring 43 is provided around the clamp 42. The lifting head 4 is fixed on the fixing ring 43 by an L-shaped rod 41 to maintain the position of the lifting head 4.

[0061] Preferably, the lifting head 4 has a spherical structure.

[0062] Preferably, the upper surface of the load-bearing plate 52 is provided with a sloping top 521, and the side of the sloping top 521 closer to the center of the tray 71 is the higher end, and the side of the sloping top 521 farther away from the center of the tray 71 is the lower end, so that the lifting head 4 can gradually push the load-bearing plate 52.

[0063] Combination Figure 6 , Figure 7 and Figure 11 As shown, in order to enable the lower surface of the soil to detach automatically, a split bottom plate 72 is provided on the upper surface of the tray 71 in the area opposite to the main body 51 of the retaining plate. Multiple split bottom plates 72 form a circular structure, and the soil is located above the circular structure. A tension rope 745 is connected between the upper surface of the split bottom plate 72 and the opposite main body 51 of the retaining plate.

[0064] In this implementation plan, when the main body 51 of the retaining plate gradually opens, it can pull the tension rope 745, which in turn can pull the split bottom plate 72, causing the split bottom plate 72 to separate from the soil bonding parts. At this time, there are no bonding positions on any of the outer surfaces of the soil, and the operator can manually remove the soil with early-maturing bluegrass.

[0065] Combination Figure 6 and Figure 7 As shown, in order to prevent the tray 71 from moving upward as a whole when it is pulled by the tension rope 745, a groove 741 is provided in the radial direction of the tray 71 in the area opposite to the middle of the split base plate 72 on the upper surface of the tray 71. A guide rod 744 is installed in the groove 741, and a slider 743 that can slide along the guide rod 744 is provided in the groove 741. A spring 742 is provided between the slider 743 and the groove 741, and the slider 743 is fixedly connected to the split base plate 72.

[0066] In this embodiment, when the tension rope 745 pulls the split base plate 72, the slider 743 slides along the guide rod 744 within the groove 741, thereby moving the split base plate 72 along the direction of the groove 741; the slider 743 slides along the guide rod 744 within the groove 741, and the slider 743 can compress the spring 742, so that when the operator... Figure 12 When the soil is removed in the state shown, the spring 742 can automatically rebound when the tray 71 and the outer cover 5 move downwards, so the split bottom plate 72 can automatically reset for the next use.

[0067] Preferably, both the tray 71 and the split base plate 72 are provided with drainage holes 73 for draining excess water. Drainage holes 73 can also be provided at the bottom of the box body 3, and drainage pipes can be provided inside the bed body 2.

[0068] Combination Figure 1 and Figure 2As shown, the aforementioned matrix-arranged box 3 is divided into a first group and a second group. The drive mechanism 21 is used to drive the trays 71 in the first group and the second group to rise and fall asynchronously, so that the holding plate bodies 51 of different groups open alternately. The alternate opening method can avoid the problem of mutual interference after the holding plate bodies 51 are opened, thereby ensuring that the holding plate bodies 51 can open smoothly and without obstruction.

[0069] like Figure 2 and Figure 13 As shown, the first group consists of non-adjacent boxes 3, and the second group consists of the remaining non-adjacent boxes 3. The drive mechanism 21 includes a short rod 91 and a long rod 92. The short rod 91 is fixed to the lower surface of the tray 71 inside the first group of boxes 3, and an upper support 215 is fixed between the lower ends of multiple short rods 91. The long rod 92 is fixed to the lower surface of the tray 71 inside the second group of boxes 3, and a lower support 214 is fixed between the lower ends of multiple long rods 92. The first cam 211 is located below the lower support 214; the second cam 213 is located below the upper support 215; the protrusions of the first cam 211 and the second cam 213 form a 90° angle; a camshaft 212 is fixed in the middle of both the first cam 211 and the second cam 213, and the camshafts 212 are connected by a belt drive structure; a drive motor 216 for driving one of the camshafts 212 is provided on the outer side of the bed 2.

[0070] In this embodiment, when the drive motor 216 rotates, it can drive one of the camshafts 212 to rotate. As a result of the transmission between the belts, all the camshafts 212 can rotate together, and the first cam 211 and the second cam 213 can rotate synchronously.

[0071] In the initial state, such as Figure 13As shown, when transplanting is required, the drive motor 216 rotates, causing the first cam 211 and the second cam 213 to rotate 90° counterclockwise synchronously. During this rotation, the protrusion of the second cam 213 reaches the lower surface of the upper support 215, while the protrusion of the first cam 211 has not yet reached the lower surface of the lower support 214. This allows the upper support 215 to drive all the short rods 91 to push the tray 71 inside the first set of boxes 3 upwards, exposing the soil and Kentucky bluegrass inside the first set of boxes 3. The operator can then remove the soil and Kentucky bluegrass. Then, the drive motor 216 is controlled to continue rotating counterclockwise by 90°, so that the protrusion of the first cam 211 reaches the lower surface of the lower support 214. At this time, the protrusion of the second cam 213 disengages from the upper support 215, thereby pushing the long rod 92 upward from the lower support 214. The upper support 215 loses the support of the protrusion of the second cam 213 and descends, so that the tray 71 in the second set of boxes 3 can move upward, thus exposing the soil and Kentucky bluegrass in the second set of boxes 3. At this time, the operator can remove the soil and Kentucky bluegrass. Then, the drive motor 216 is controlled to continue rotating counterclockwise by 180° to restore the original position. Figure 13 The state shown.

[0072] By adopting this staggered opening method, the problem of mutual interference after the main body 51 of the retaining plate is opened can be avoided, thereby ensuring that the main body 51 of the retaining plate can open smoothly and without obstruction.

[0073] Preferably, in order to facilitate the spraying of waste materials on Kentucky bluegrass, a spraying mechanism 1 is provided on the upper side of one side of the bed body 2. The spraying mechanism 1 includes a side plate 101 fixed on the upper side of one side of the bed body 2, a spraying pipe 102 provided on the upper side of the side plate 101 near the bed body 2, and a nozzle 103 fixed on the lower surface of the spraying pipe 102. The spraying pipe 102 is connected to a pesticide supply box. Under the operation of the pump, the liquid fertilizer can reach the spraying pipe 102 and then be sprayed out from the nozzle 103.

[0074] When using (working), insert the rhizomes into a propagation bed with soil to maintain the condition of the transplanted roots. Keep the rhizomes in the propagation bed with soil to maintain the condition of the transplanted roots for at least one day. Then cut and remove the bottom leaves, leaving the top leaves. Leaving the top leaves is to maintain the photosynthesis of Kentucky bluegrass. In the first 1-2 months, Kentucky bluegrass mainly consumes its own nutrients to expand and increase the number of leaves. Apply a light fertilizer to Kentucky bluegrass in the first 2-5 months. Transplant Kentucky bluegrass before 5-6 months of age, keeping the soil and the root system intact when transplanting. Apply fertilizer in the later stage of establishment, 6-9 months of age, to expand and increase the number of stems.

[0075] During transplanting, the drive motor 216 rotates, causing the first cam 211 and the second cam 213 to rotate 90° counterclockwise synchronously. During this rotation, the protrusion of the second cam 213 reaches the lower surface of the upper support 215, while the protrusion of the first cam 211 has not yet reached the lower surface of the lower support 214. This allows the upper support 215 to drive all the short rods 91 to push the tray 71 inside the first set of boxes 3 upwards, enabling the tray 71 to move upwards and reach its destination. Figure 9 and Figure 10 As shown, the tray 71 continues to move upward, and the lifting head 4 can push the force plate 52, causing the main body of the clamping plate 51 to open and detach from the outer arc surface of the soil.

[0076] In this embodiment, the outer retaining plate 5 moves upward with the tray 71 until the force plate 52 reaches the position of the lifting head 4. At this time, the lifting head 4 can push the force plate 52, thereby causing the outer retaining plate 5 to rotate along the pin 53, thus opening the retaining plate body 51 and separating it from the outer surface of the soil (see reference). Figure 11 and Figure 12 As shown, when the main body 51 of the retaining plate gradually opens, it can pull the tension rope 745, which in turn can pull the split bottom plate 72, causing the split bottom plate 72 to separate from the soil bonding parts. At this time, there are no bonding positions on any of the outer surfaces of the soil, and the operator can manually remove the soil with early-maturing bluegrass from the tray 71.

[0077] Then, the drive motor 216 is controlled to continue rotating counterclockwise by 90°, so that the protrusion of the first cam 211 reaches the lower surface of the lower support 214. At this time, the protrusion of the second cam 213 disengages from the upper support 215, thereby pushing the long rod 92 upward from the lower support 214. The upper support 215 loses the support of the protrusion of the second cam 213 and descends, so that the tray 71 in the second set of boxes 3 can move upward, thus exposing the soil and Kentucky bluegrass in the second set of boxes 3. At this time, the operator can remove the soil and Kentucky bluegrass. Then, the drive motor 216 is controlled to continue rotating counterclockwise by 180° to restore the original position. Figure 13 The state shown indicates that the plant is ready to reproduce the next batch of Kentucky bluegrass.

[0078] Example 2: Combination Figure 14 and Figure 15 As shown.

[0079] The difference between this embodiment and Embodiment 1 is that a rotating disk 75 is rotatably mounted on the outer periphery of the upper surface of the tray 71, and an intermediate disk 78 is rotatably mounted on the middle of the upper surface of the tray 71. A flexible mesh 77 is provided between the intermediate disk 78 and the rotating disk 75. When soil is placed above the intermediate disk 78 and the rotating disk 75, the mesh 77 can reduce the amount of soil falling below the intermediate disk 78 and the rotating disk 75. In addition, the flexible mesh 77 can also compensate for the rotation of the rotating disk 75.

[0080] A force-bearing block 76 is fixedly provided on the outer side of the lower surface of the rotating disk 75. A force-bearing groove 761 is provided on the outer surface of the force-bearing block 76. The force-bearing groove 761 is a spiral groove with the center of the rotating disk 75 as the center. A force-applying rod 79 is fixedly provided on the inner wall of the box body 3 in the area opposite to the force-bearing groove 761, so that when the tray 71 moves upward, the force-applying rod 79 can push the rotating disk 75 to rotate, so that the rotating disk 75 and the soil bonding position are separated from each other.

[0081] Preferably, a toothed ring 1 is provided on the outer periphery of the rotating disk 75, and a toothed ring 2 is also provided on the outer surface of the intermediate disk 78. The toothed ring 1 and the toothed ring 2 mesh with each other so that the rotation of the rotating disk 75 can drive the intermediate disk 78 to rotate, thereby allowing the intermediate disk 78 to also separate from the bottom of the soil, further facilitating the operator to remove the Kentucky bluegrass and its root soil from the tray 71.

[0082] When in use (working), when transplanting is required, the short rod 91 pushes the tray 71 inside the first set of boxes 3 upwards, allowing the tray 71 inside the first set of boxes 3 to move upwards. As a result, the force-bearing block 76 also rises. During the upward movement, the force groove 761 and the force-applying rod 79 work together to rotate the force-bearing block 76 by a small angle. This small angle of rotation allows the bottom of the soil to separate from the rotating disk 75. In addition, when the rotating disk 75 rotates, the gear ring on it causes the middle disk 78 to rotate synchronously, thus achieving the purpose of separating the middle disk 78 from the bottom of the soil. As the short rod 91 continues to rise, the lifting head 4 pushes the force plate 52, causing the outer clamping plate 5 to rotate along the pin shaft 53. This causes the clamping plate body 51 to open, separating it from the outer surface of the soil. The clamping plate body 51 gradually opens, and at this point, there are no sticky areas on any of the outer surfaces of the soil. The operator can then manually remove the soil containing the Kentucky bluegrass from the tray 71.
