Description

Technical Field

[0001] The invention relates to the technical field of bluegrass reproduction, in particular to an asexual reproduction and rejuvenation method for bluegrass. Background Art

[0002] Poa pratensis is a rhizome-propagating grass species. It is cold-resistant, drought-tolerant, and has fast rhizome propagation. It is a typical community-building species on the Qinghai-Tibet Plateau and a core grass species used for ecological restoration. Poa pratensis can reproduce by seeds or rhizomes. One of its major characteristics that distinguishes it from non-rhizome plants is that the cloned ramets of Poa pratensis undergo physiological integration through the connection parts, and arrange their growth pattern by changing the length of the spacer and the angle of the branch, so that the degree of attraction and utilization of resources reaches an ideal level, thereby achieving resource sharing among the ramets. The asexual reproduction strategy of Poa pratensis is the product of its long-term adaptation to the harsh environment of the Qinghai-Tibet Plateau. It is not only determined by natural biological processes, but also by environmental factors that strongly affect the plant's reproduction strategy.

[0003] In the prior art, the asexual reproduction and rejuvenation method of Poa annua generally adopts the method of stem division, that is, the stems are cultivated after being divided and then transplanted to the desired location.

[0004] In the prior art, the propagation bed is generally transplanted by digging, and the roots need to retain the soil when digging out. However, the digging method can easily lead to root breakage, and the soil is incomplete and cannot cover the roots in all directions, resulting in a decrease in the survival rate of the subsequent early grass. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a method for asexual reproduction and rejuvenation of Poa annua, which solves the problem in the prior art that the digging method during asexual reproduction and rejuvenation of Poa annua easily leads to root breakage, and the soil is incomplete and cannot cover the roots in all directions, resulting in a decrease in the survival rate of the subsequent Poa annua.

[0009] Furthermore, a slope top is provided on the upper surface of the force-bearing plate, and a side of the slope top close to the center of the tray is a higher end, and a side of the slope top away from the center of the tray is a lower end.

[0010] Furthermore, a split bottom plate is provided in the area of ​​the upper surface of the pallet opposite to the holding board body, and a plurality of the split bottom plates form a circular structure; a tension rope is connected between the upper surface of the split bottom plate and the opposite holding board body, so that the split bottom plate can be pulled when the holding board body is opened, so that the split bottom plate and the soil bonding part are separated from each other.

[0011] Furthermore, a groove is provided in the radial direction of the tray in an area opposite to the middle of the split bottom plate on the upper surface of the tray, a guide rod is installed in the groove, a slider capable of sliding 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 bottom plate.

[0013] Furthermore, a first gear ring is provided on the periphery of the rotating disk, and a second gear ring is also provided on the outer surface of the intermediate disk. The first gear ring is meshed with the second gear ring, so that the rotation of the rotating disk can drive the rotation of the intermediate disk.

[0014] Furthermore, the box bodies arranged in a matrix are divided into a first group and a second group, and the driving mechanism is used to drive the trays in the first group and the second group to rise and fall asynchronously so that the holding bodies of different groups are staggered and opened; the first group is composed of non-adjacent box bodies, and the second group is composed of remaining non-adjacent box bodies; the driving mechanism includes: a short rod, which is fixed to the lower surface of the tray in the box body constituting the first group, and an upper bracket 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 body constituting the second group, and a lower bracket is fixed between the lower ends of multiple groups of long rods; a first cam, which is located below the lower bracket; a second cam, which is located above the upper bracket; the protrusions of the first cam and the second cam form an angle of 90°; a camshaft is fixed in the middle of the first cam and the second cam, and the camshafts are connected by a belt transmission structure; a driving motor for driving one of the camshafts is provided on one side of the outer side of the bed.

[0016] The present invention has the following beneficial effects: (1) The asexual reproduction and rejuvenation method of the bluegrass is to set up a propagation bed that can maintain the state of the transplanted roots, so that the bluegrass is transplanted by pushing out rather than digging out the roots. This method can not only prevent the roots of the bluegrass from being dug up, but also ensure that all the soil is pushed out so that the roots are completely covered by the soil, thereby improving the survival rate of the bluegrass after transplanting.

[0017] (2) The asexual reproduction and rejuvenation method of the bluegrass is provided with an outer holding plate. When the soil is separated upward from the box body, the area where the soil contacts the outer holding plate can be wrapped, and the soil in this area will not separate from the outer holding plate, that is, the force on the soil is greatly reduced, thereby avoiding the fracture and partial shedding of the soil and the exposure of the roots of the bluegrass. In addition, the outer holding plate can open by itself to separate from the soil; that is, the separation of the outer surface of the soil is divided into two steps, the first step is to separate from the box body, and the second step is to separate from the outer holding plate, thereby reducing the external force on the soil when it separates and avoiding the soil from breaking.

[0018] (3) The asexual reproduction and rejuvenation method of the bluegrass is provided with a split bottom plate. When the main body of the holding plate is gradually opened, it can pull the tension rope, so that the tension rope can pull the split bottom plate, so that the split bottom plate and the bonding parts of the soil are separated from each other. At this time, all the outer surfaces of the entire soil have no bonding positions, and the operator can manually remove the soil with the bluegrass from the tray.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0024] According to the following Figure 1-Figure 15 The invention discloses a method for asexual reproduction and rejuvenation of bluegrass provided by the invention.

[0025] Example 1: Please refer to Figure 1-Figure 13 shown.

[0026] The embodiment of the present invention provides a method for asexual reproduction and rejuvenation of bluegrass, comprising the following steps: S1: Select bluegrass that has been planted for 3-4 years and has reduced production and degenerated, and manually divide the rhizomes of bluegrass into several ramets, and insert the rhizomes into a propagation bed with soil that can maintain the state of the transplanted roots. Bluegrass that is 3-4 years old is considered old bluegrass, and selecting this type of bluegrass can extend the utilization period of bluegrass; S2: The rhizomes are inserted into a propagation bed with soil that can maintain the state of transplanted roots for at least one day, and then the bottom leaves are cut off and removed, and the top leaves are retained. The top leaves are retained to maintain the photosynthesis of the bluegrass. S3: At 1-2 months old, bluegrass mainly consumes its own nutrients to expand and increase leaves. Apply thin fertilizer to bluegrass at 2-5 months old. S4: Transplant bluegrass before 5-6 months of age, retaining the soil and intact root system when transplanting; S5: Apply fertilizer at the end of the planting period (6-9 months) to expand and increase the number of stems.

[0027] like Figure 2-Figure 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, and the box bodies 3 serve as a growth place for bluegrass.

[0028] Preferably, the length, width and height of the bed 2 are respectively: 1.5m*1m*0.8m.

[0029] Combination Figure 4-Figure 8 As shown, a tray 71 is provided at the bottom of the box body 3, and an outer holding board 5 is provided on the periphery of the tray 71. There is a spacing space between two adjacent outer holding boards 5. The space formed by the tray 71 and the outer holding board 5 is used to store soil. When the root diameter of the early grass is inserted into the breeding bed with soil that can maintain the state of the transplanted roots, it is actually inserted into the soil in the space formed by the tray 71 and the outer holding board 5. A driving mechanism 21 that can drive the tray 71 and the outer holding board 5 to rise is provided in the bed body 2, so that the soil carrying the 5-6 month old early grass is separated from the box body 3 upward. When the early grass and the soil carried thereon are separated from the box body 3 upward, the entire soil is exposed above the box body 3, so that the operator can easily take out the entire soil. Compared with digging out the soil in the prior art, the root system can be avoided from being broken.

[0030] It should be noted that if the outer holding plate 5 is not provided, the tray 71 directly pushes the soil upwards, which causes all positions on the outer surface of the soil to be synchronously separated from the box body 3, resulting in a huge external force on the soil. Once the soil is loose, the agglomerated soil will break and partially fall off, exposing the roots.

[0031] On the contrary, when the outer holding board 5 is provided, the area where the soil contacts the outer holding board 5 can be wrapped when the soil separates upward from the box body 3, and the soil in this area will not separate from the outer holding board 5, that is, the stress on the soil is greatly reduced, thereby avoiding the breakage and partial falling of the soil and preventing the roots of the bluegrass from being exposed.

[0032] Combination Figure 5 , Figure 9-12As shown, in this embodiment, after the soil is upwardly separated from the box body 3, the outer holding board 5 is automatically separated from the soil outward, specifically as follows: the outer holding board 5 includes a holding board body 51, and the holding board body 51 is surrounded by the outer periphery of the tray 71 in a matrix manner, and the lower middle part of the holding board body 51 is rotatably connected with the tray 71 through a pin 53, and a force plate 52 is provided at the lower end of one side of the holding board body 51; a lifting head 4 is provided on the outer periphery of the upper end of the box body 3, and the lifting head 4 is vertically opposite to the force plate 52, and the side of the lifting head 4 close to the center of the box body 3 protrudes from the inner surface of the force plate 52, so that after the outer holding board 5 rises with the tray 71, the lifting head 4 can push the force plate 52, so that the holding board body 51 opens and separates from the outer arc surface of the soil.

[0033] In this embodiment, the outer holding 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, so that the outer holding plate 5 rotates along the pin 53, so that the holding plate body 51 opens and separates from the outer surface of the soil (refer to Fig.11 and Fig.12 as shown).

[0034] In summary, the present invention divides the detachment of the outer surface of the soil into two steps, the first step is detachment from the box body 3, and the second step is detachment from the outer holding plate 5, thereby reducing the external force applied to the soil during detachment and avoiding soil fracture.

[0035] Preferably, a clamp 42 is fixedly provided on the outer surface of the upper end of the box body 3 , a fixing ring 43 is provided on the periphery of the clamp 42 , and the jacking head 4 is fixed on the fixing ring 43 through an L-shaped rod 41 to maintain the position of the jacking head 4 .

[0036] Preferably, the lifting head 4 is a spherical structure.

[0037] Preferably, a slope top 521 is provided on the upper surface of the force-bearing plate 52 , and the side of the slope top 521 close to the center of the tray 71 is the higher end, and the side of the slope top 521 away from the center of the tray 71 is the lower end, so that the lifting head 4 can gradually push the force-bearing plate 52 .

[0038] Combination Figure 6 , Figure 7 and Fig.11 As shown, in order to allow the lower surface of the soil to automatically detach, a split bottom plate 72 is provided on the upper surface of the tray 71 in the area opposite to the holding board body 51. The 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 holding board body 51.

[0039] In this embodiment, when the holding board body 51 gradually opens, it can pull the tension rope 745, so that the tension rope 745 can pull the split bottom plate 72, so that the split bottom plate 72 and the soil bonding part are separated from each other. At this time, all the outer surfaces of the entire soil have no bonding positions, and the operator can manually remove the soil with bluegrass.

[0040] 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 opened along the radial direction of the tray 71 in the area on the upper surface of the tray 71 opposite to the middle of the split bottom plate 72, and a guide rod 744 is installed in the groove 741. The groove 741 has a slider 743 that can slide along the guide rod 744, and a spring 742 is provided between the slider 743 and the groove 741, and the slider 743 is fixedly connected to the split bottom plate 72.

[0041] In this embodiment, when the tension rope 745 pulls the split bottom plate 72, the slider 743 slides along the guide rod 744 in the groove 741, so that the split bottom plate 72 moves along the direction of the groove 741; the slider 743 slides along the guide rod 744 in the groove 741, and the slider 743 can compress the spring 742, so when the operator is in Fig.12 After the soil is removed in the state shown, when the tray 71 and the outer holding plate 5 move downward, the spring 742 can automatically rebound, so the split bottom plate 72 can automatically reset for the next use.

[0042] Preferably, a water leakage hole 73 is provided on both the tray 71 and the split bottom plate 72 for draining excess water. A water leakage hole 73 may also be provided at the bottom of the box body 3 , and a drainage pipe may be provided in the bed body 2 .

[0043] Combination Figure 1 and Figure 2 As shown, the above-mentioned box bodies 3 arranged in a matrix are divided into a first group and a second group, and the driving mechanism 21 is used to drive the trays 71 in the first group and the second group to rise and fall asynchronously, so that different groups of holding board bodies 51 are staggered to open. The staggered opening method can avoid the problem of mutual influence after the holding board bodies 51 are opened, thereby ensuring that the holding board bodies 51 can be opened smoothly and unobstructed.

[0044] like Figure 2 and Fig.13As shown, the above-mentioned first group is composed of non-adjacent box bodies 3, and the second group is composed of remaining non-adjacent box bodies 3. The driving 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 in the first group of box bodies 3, and an upper bracket 215 is fixed between the lower ends of multiple groups of short rods 91. The long rod 92 is fixed to the lower surface of the tray 71 in the second group of box bodies 3, and a lower bracket 214 is fixed between the lower ends of multiple groups of long rods 92. The first cam 211 is located below the lower bracket 214; the second cam 213, the second cam 213 is located below the upper bracket 215; the protrusions of the first cam 211 and the second cam 213 are at an angle of 90°; the middle parts of the first cam 211 and the second cam 213 are fixed with camshafts 212, and the camshafts 212 are connected by a belt transmission structure; a driving motor 216 for driving one of the camshafts 212 is provided on the outer side of the bed body 2.

[0045] In this embodiment, when the driving motor 216 rotates, it can drive one of the camshafts 212 to rotate, so that due to the transmission between the belts, all the camshafts 212 can rotate together, and then the first cam 211 and the second cam 213 can rotate synchronously.

[0046] In the initial state, if Fig.13 As shown, when transplanting is needed, the first cam 211 and the second cam 213 are synchronously rotated 90° counterclockwise by driving the motor 216. When the second cam 213 rotates, the convex portion of the second cam 213 reaches the lower surface of the upper bracket 215. At this time, the convex portion of the first cam 211 has not yet reached the lower surface of the lower bracket 214, so that the upper bracket 215 can drive all the short rods 91 to synchronously push the tray 71 in the first group of box bodies 3 upward, so that the tray 71 in the first group of box bodies 3 can move upward, so that the soil and bluegrass in the first group of box bodies 3 can be exposed. At this time, the operator takes out the soil and bluegrass. The driving motor 216 is then controlled to continue to rotate counterclockwise by 90°, so that the convex portion of the first cam 211 reaches the lower surface of the lower bracket 214. At this time, the convex portion of the second cam 213 is separated from the upper bracket 215, so that the lower bracket 214 pushes the long rod 92 upward, and the upper bracket 215 loses the support of the convex portion of the second cam 213 and descends, so that the tray 71 in the second group of box bodies 3 can move upward, so that the soil and bluegrass in the second group of box bodies 3 can be exposed. At this time, the operator can take out the soil and bluegrass, and then control the driving motor 216 to continue to rotate counterclockwise by 180° to restore to the original state. Fig.13 Status shown.

[0047] This staggered opening method can avoid the problem of the holding board main bodies 51 affecting each other after opening, thereby ensuring that the holding board main bodies 51 can be opened smoothly and without obstruction.

[0048] Preferably, in order to facilitate the spraying of waste on the bluegrass, a spraying mechanism 1 is provided above one side of the bed 2; the spraying mechanism 1 includes a side panel 101 fixed above one side of the bed 2, a spraying pipe 102 provided on the side panel 101 close to the upper side of the bed 2, and a nozzle 103 fixed on the lower surface of the spraying pipe 102. The spraying pipe 102 is connected to the pesticide supply box. When the pump is working, the liquid fertilizer can reach the spraying pipe 102 and then be sprayed out from the nozzle 103.

[0049] When in use (working), insert the rhizome into a propagation bed with soil that can maintain the state of the roots for transplanting. The rhizome inserted into the propagation bed with soil that can maintain the state of the roots for transplanting should be maintained in this state for at least one day, then cut off and remove the bottom leaves, and retain the top leaves. The top leaves are retained to maintain the photosynthesis of early grass. At 1-2 months old, early grass mainly consumes its own nutrients to expand and increase the leaves. Apply thin fertilizer to early grass at 2-5 months old. Transplant early grass before 5-6 months old. Keep the soil and intact root system of the root system during transplanting. Apply fertilizer in the late establishment period of 6-9 months to expand and increase the stems.

[0050] During transplanting, the first cam 211 and the second cam 213 are synchronously rotated 90° counterclockwise by driving the motor 216. When the second cam 213 rotates, the convex portion of the second cam 213 reaches the lower surface of the upper bracket 215. At this time, the convex portion of the first cam 211 has not yet reached the lower surface of the lower bracket 214, so that the upper bracket 215 can drive all the short rods 91 to synchronously push the tray 71 in the first group of box bodies 3 upward, so that the tray 71 in the first group of box bodies 3 can move upward, so that the tray 71 can reach Fig. 9 and Fig.10 In the state shown, the tray 71 continues to move upward, and the lifting head 4 can push the force-bearing plate 52, so that the outer arc surface of the holding plate body 51 is opened and separated from the soil.

[0051] In this embodiment, the outer holding 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, so that the outer holding plate 5 rotates along the pin 53, so that the holding plate body 51 opens and separates from the outer surface of the soil (refer to Fig.11 and Fig.12 As shown in the figure, when the holding board body 51 is gradually opened, it can pull the tension rope 745, so that the tension rope 745 can pull the split bottom plate 72, so that the split bottom plate 72 and the soil bonding part are separated from each other. At this time, all the outer surfaces of the entire soil have no bonding positions, and the operator can manually remove the soil with bluegrass from the tray 71.

[0052] Then, the driving motor 216 is controlled to continue to rotate counterclockwise by 90°, so that the convex part of the first cam 211 reaches the lower surface of the lower bracket 214. At this time, the convex part of the second cam 213 is separated from the upper bracket 215, so that the lower bracket 214 pushes the long rod 92 upward, and the upper bracket 215 loses the support of the convex part of the second cam 213 and descends, so that the tray 71 in the second group of box bodies 3 can move upward, so that the soil and bluegrass in the second group of box bodies 3 can be exposed. At this time, the operator can take out the soil and bluegrass, and then control the driving motor 216 to continue to rotate counterclockwise by 180° to restore to normal. Fig.13 The state shown, waiting for the next batch of bluegrass to be bred.

[0053] Embodiment 2: Combination Fig.14 and Fig.15 shown.

[0054] The difference between this embodiment and the first embodiment is that a rotating disk 75 is rotatably installed on the outer periphery of the upper surface of the tray 71, and an intermediate disk 78 is rotatably installed on the middle part of the upper surface of the tray 71. A flexible gauze 77 is provided between the intermediate disk 78 and the rotating disk 75. Soil is placed above the intermediate disk 78 and the rotating disk 75. The gauze 77 can reduce the amount of soil falling below the intermediate disk 78 and the rotating disk 75. In addition, the flexible gauze 77 can also compensate for the rotation amount of the rotating disk 75.

[0055] A force block 76 is fixedly provided on the outer side of the lower surface of the rotating disk 75, and a force groove 761 is opened on the outer surface of the force block 76, and the force groove 761 is a spiral groove with the center of the rotating disk 75 as the center. A force rod 79 is fixedly provided on the area of ​​the inner wall of the box body 3 opposite to the force groove 761, so that when the tray 71 moves upward, the force 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.

[0056] Preferably, a gear ring 1 is provided on the periphery of the rotating disk 75, and a gear ring 2 is also provided on the outer surface of the intermediate disk 78. The gear ring 1 is meshed with the gear ring 2, so that the rotation of the rotating disk 75 can drive the intermediate disk 78 to rotate, so that the intermediate disk 78 can also be separated from the bottom surface of the soil, further facilitating the operator to remove the bluegrass and its root soil from the tray 71.

[0057] During use (working), when transplanting is required, the short rod 91 synchronously pushes the tray 71 in the first group of box bodies 3 upward, so that the tray 71 in the first group of box bodies 3 can move upward, so that the force block 76 can also rise accordingly. During the rising process, the force groove 761 and the force applying rod 79 cooperate to enable the force block 76 to rotate a small angle. This small angle of rotation can cause the bottom of the soil to separate from the rotating disk 75. In addition, when the rotating disk 75 rotates, the gear ring thereon can cause the intermediate disk 78 to rotate synchronously, thereby achieving the purpose of separating the intermediate disk 78 from the bottom surface of the soil. As the short rod 91 continues to rise, the lifting head 4 can push the force plate 52, so that the outer holding plate 5 rotates along the pin shaft 53, so that the holding plate body 51 opens, so that it is separated from the outer surface of the soil, and the holding plate body 51 gradually opens. At this time, there is no bonding position on the outer surfaces of the entire soil, and the operator can manually remove the soil with bluegrass from the tray 71.
