Description

Technical Field

[0001] This application relates to the field of plant grafting, and in particular to a peony grafting wrapping device and method. Background Technology

[0002] The cambium is an active tissue in a plant that has the ability to divide. In the process of grafting peonies, it is necessary to ensure that the cambium of the scion and the rootstock are aligned in order to ensure the survival rate of the graft.

[0003] Currently, peony grafting is done manually. Operators use a blade to make a slanted cut on the rootstock at an appropriate location, then shape the scion into a wedge and insert it into the cut. Finally, the scion and rootstock are tied together and fixed in place. Because operators usually rely on experience to cut the rootstock and scion, the angle and size of the cuts on the scion and rootstock are somewhat random. When inserting the scion into the cut on the rootstock, it is difficult to guarantee the alignment range between the cambium layer of the scion and the cambium layer of the rootstock, making it difficult to control the grafting survival rate. Summary of the Invention

[0004] To ensure the alignment range of the cambium layers of the scion and rootstock, this invention provides a peony grafting wrapping device and a peony grafting wrapping method.

[0005] This application provides a peony grafting and wrapping device and method, which adopts the following technical solution:

[0006] A peony grafting incision includes a first incision and a second incision. The first incision is formed on the rootstock, and the second incision is formed on the scion. The rootstock has a first end face facing the scion. The first incision has a first longitudinal section, which forms a first angle with the first end face. The scion has a second end face facing the rootstock. The second incision has a second longitudinal section, which forms a second angle with the second end face. The first angle and the second angle are equal. The rootstock has a first projection plane perpendicular to the first longitudinal section and the first end face. The projection of the first longitudinal section onto the first projection plane is a first line segment, which has a first endpoint located away from the first end face. The scion has a second projection plane perpendicular to the second longitudinal section and the second end face. The projection of the second longitudinal section onto the second projection plane is a second line segment, which has a second endpoint located away from the second end face. The distance between the first endpoint and the first end face is equal to the distance between the second endpoint and the second end face. The first longitudinal section and the second longitudinal section are in contact.

[0007] Optionally, both the first included angle and the second included angle are obtuse angles.

[0008] Optionally, the first cut has a first transverse surface arranged parallel to the first end face, which intersects with the first longitudinal surface; the second cut has a second transverse surface arranged parallel to the second end face, which intersects with the second longitudinal surface, so that when the first longitudinal surface is attached to the second longitudinal surface, the first transverse surface is attached to the second transverse surface.

[0009] This application provides a peony grafting and wrapping device, suitable for forming the peony grafting incision and wrapping the rootstock and scion; the peony grafting and wrapping device includes a support, a cutting assembly, and a wrapping assembly, the support including a support plate for supporting the rootstock or the scion; the cutting assembly including a slide and a blade assembly, the slide being slidably connected to the support, the blade assembly being connected to the slide, and the blade assembly having a blade edge arranged towards the support plate; the wrapping assembly including a reel and a hemp rope, the reel being connected to the support, the hemp rope being wound around the reel, and the hemp rope being used to wrap the rootstock and the scion when the first longitudinal section and the second longitudinal section are in contact.

[0010] Optionally, the blade assembly includes a longitudinal cutter and two transverse cutters. The longitudinal cutter is connected to the carriage, and the two transverse cutters are respectively disposed on both sides of the longitudinal cutter and connected to the longitudinal cutter, so as to form the first longitudinal section and the second longitudinal section through the longitudinal cutter, and to form the first transverse section and the second transverse section through the transverse cutters.

[0011] Optionally, the longitudinal cutter is rotatably connected to the carriage, and the transverse cutter is hinged to the longitudinal cutter.

[0012] Optionally, a rotating shaft is rotatably connected to the carriage, the rotating shaft is connected to the longitudinal cutter, and a protractor is provided on the carriage, the protractor having scale lines arranged circumferentially along the rotating shaft.

[0013] Optionally, the peony grafting and wrapping device further includes a limiting rod, the length direction of which is perpendicular to the length direction of the rootstock. The limiting rod is slidably connected to the cross-cutting blade so as to limit the size of the first cross-section by the limiting rod being attached to the side of the rootstock, and to limit the size of the second cross-section by the limiting rod being attached to the side of the scion.

[0014] Optionally, the peony grafting and wrapping device further includes a guide assembly, which includes a guide rod, a guide sleeve, and a spring. The guide rod slides through the guide sleeve. One of the guide rod and the guide sleeve is connected to the slide, and the other is connected to the support. The spring is used to apply elastic force to the guide rod and the guide sleeve respectively, so that the guide rod and the guide sleeve tend to move away from each other.

[0015] This application provides a method for wrapping peony grafts, using the aforementioned peony grafting wrapping device. The method includes the following steps:

[0016] S1: Place the rootstock and the scion on the support plate in sequence, and use the blade assembly to cut the rootstock and the scion to form the first incision on the rootstock and the second incision on the scion;

[0017] S2: Align the rootstock with the scion, and make the first longitudinal section and the second longitudinal section fit together;

[0018] S3: Use the hemp rope to wrap the rootstock and the scion to complete the wrapping of the rootstock and the scion.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The peony grafting incision in this application embodiment, by limiting the angles of the first incision and the second incision to be equal and their sizes to match, ensures that the cambium alignment range of the rootstock and the scion is not less than 60% when the first incision of the rootstock and the second incision of the scion are aligned, thereby controlling the survival rate of peony grafting at a high level.

[0021] 2. By setting the first longitudinal section and the second longitudinal section at an angle, and simultaneously setting the first cross section and the second cross section, the alignment range of the cambium layers of the rootstock and scion can be increased while ensuring the relative position of the rootstock and scion is stable. This improves the convenience of the wrapping operation during peony grafting and increases the survival rate of peony grafting.

[0022] 3. The peony grafting and wrapping device of this application cuts the rootstock and scion with the cutting component, and controls the angle and size of the first cut and the second cut to match, thereby ensuring the survival rate of peony grafting. The wrapping component wraps the rootstock and scion, which can improve the wrapping efficiency. Attached Figure Description

[0041] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0042] This application discloses a grafting incision for peony. (Refer to...) Figures 1 to 3 The peony grafting incision includes a first incision and a second incision. The first incision is formed on the rootstock 10, and the second incision is formed on the scion 20. The rootstock 10 has a first end face 101 facing the scion 20, which is perpendicular to the length direction of the rootstock 10. The first incision has a first longitudinal section 102, which forms a first angle α with the first end face 101. The scion 20 has a second end face 201 facing the rootstock 10, which is perpendicular to the length direction of the scion 20. The second incision has a second longitudinal section 202, which forms a second angle α with the second end face 201. Angle β, the first included angle and the second included angle are equal; the rootstock 10 has a first projection plane perpendicular to the first longitudinal section 102 and the first end face 101, the projection of the first longitudinal section 102 on the first projection plane is a first line segment, the first line segment has a first end point arranged away from the first end face 101, the scion 20 has a second projection plane perpendicular to the second longitudinal section 202 and the second end face 201, the projection of the second longitudinal section 202 on the second projection plane is a second line segment, the second line segment has a second end point arranged away from the second end face 201, the distance between the first end point and the first end face 101 is equal to the distance between the second end point and the second end face 201.

[0043] The first projection plane is a longitudinal section that coincides with the axis of the rootstock 10, and the second projection plane is a longitudinal section that coincides with the axis of the scion 20.

[0044] In this embodiment of the peony grafting incision, by limiting the first included angle and the second included angle to be equal, and by limiting the distance between the first endpoint and the first end face 101 to be equal to the distance between the second endpoint and the second end face 201, the angles of the first incision and the second incision can be limited to be equal and their sizes matched. When the first incision of the rootstock 10 and the second incision of the scion 20 are aligned, the alignment range of the cambium of the rootstock 10 and the scion 20 can be guaranteed to be no less than 60%, thereby controlling the survival rate of peony grafting at a high level.

[0045] Optionally, the diameter difference between the rootstock 10 and the scion 20 is 0~0.5mm, preferably 0~0.2mm; thereby, the cambium alignment range of the rootstock 10 and the scion 20 can be further improved, ensuring the survival rate of peony grafting.

[0046] The peony grafting incisions in this application embodiment include three types. To facilitate the description of these three types of peony grafting incisions, the part cut off from the rootstock 10 is named the first cut body, and the part cut off from the scion 20 is named the second cut body. The first incision is formed after the first cut body is cut off from the rootstock 10, and the second incision is formed after the second cut body is cut off from the scion 20.

[0047] Reference Figure 1This is the first type of grafting incision for peonies. The projections of the first excised body on the first projection plane and the second excised body on the second projection plane are both triangles, with equal dimensions and angles. The first longitudinal section 102 and the second longitudinal section 202 are both arranged at an angle, such that the first included angle α and the second included angle β are both obtuse angles, and the first included angle α and the second included angle β are between 100° and 130°. This increases the area of ​​the first longitudinal section 102 and the second longitudinal section 202, resulting in a larger contact area between the first longitudinal section 102 and the second longitudinal section 202 when the rootstock 10 and the scion 20 are grafted. By adjusting the relative positions of the rootstock 10 and the scion 20, the alignment range of their cambium layers can be increased, thereby improving the survival rate of peony grafting.

[0048] Reference Figure 2 This is the second type of grafting incision for peony. The projections of the first excised body and the second excised body on the first projection plane are both rectangles. The first included angle α and the second included angle β are both right angles. That is, the first incision has a first longitudinal section 102 perpendicular to the first end face 101 and a first transverse section 103 arranged parallel to the first end face 101. The second incision has a second longitudinal section 202 perpendicular to the second end face 201 and a second transverse section 203 arranged parallel to the second end face 201. The projections of the first end face 101 on the first projection plane and the second transverse section 203 on the second projection plane are both line segments and their lengths are equal. Therefore, when the rootstock 10 and the scion 20 are grafted, the first longitudinal section 102 and the second longitudinal section 202 are in contact, the first end face 101 and the second transverse section 203 are in contact, and one side of the rootstock 10 and the scion 20 are flush, which can further increase the alignment range of the cambium of the rootstock 10 and the scion 20 and improve the survival rate of peony grafting.

[0049] Furthermore, since the first longitudinal section 102 and the first transverse section 103 are perpendicular to each other, and the second longitudinal section 202 and the second transverse section 203 are perpendicular to each other, the relative positions of the rootstock 10 and the scion 20 can be restricted. When the rootstock 10 and the scion 20 are wrapped, their relative positions are more stable, thereby improving the convenience of the wrapping operation during peony grafting.

[0050] Reference Figure 3This is the third type of peony grafting incision. The third type is similar to the second type, but differs in that the projections of the first excised section on the first projection plane and the second excised section on the second projection plane are both right-angled trapezoids, meaning both the first included angle α and the second included angle β are obtuse angles, and these angles are between 100° and 130°. Therefore, when grafting the rootstock 10 and scion 20, the contact area between the first longitudinal section 102 and the second longitudinal section 202 is larger. This ensures a stable relative position for the rootstock 10 and scion 20 while increasing the alignment range of their cambium layers, thereby further improving the survival rate of the grafted peony.

[0051] This application also discloses a peony grafting and wrapping device, as shown in the embodiments below. Figure 4 and Figure 5 The peony grafting and wrapping device includes a support 1, a cutting component 2, and a wrapping component 3. The support 1 includes a support plate 11 for supporting the rootstock 10 or the scion 20. The cutting component 2 includes a slide 21 and a blade assembly 22. The slide 21 is slidably connected to the support 1, and the blade assembly 22 is connected to the slide 21. The blade assembly 22 has blades arranged towards the support plate 11. The wrapping component 3 includes a reel 31 and a hemp rope 32. The reel 31 is connected to the support 1, and the hemp rope 32 is wound around the reel 31. The hemp rope 32 is used to wrap the rootstock 10 and the scion 20.

[0052] Place the rootstock 10 or scion 20 on the support plate 11, and control the slide 21 to move the blade assembly 22 towards the support plate 11. This allows the rootstock 10 to be cut and form the first incision, and the scion 20 to be cut and form the second incision. Then, align the rootstock 10 and scion 20 so that the first longitudinal section 102 and the second longitudinal section 202 fit together. Finally, use the hemp rope 32 on the reel 31 to wrap the rootstock 10 and scion 20 to complete the wrapping of the rootstock 10 and scion 20, thus realizing the peony grafting.

[0053] The peony grafting and wrapping device of this application embodiment cuts the rootstock 10 and scion 20 with the blade assembly 22. It can control the angle and size of the first cut and the second cut to match. When the rootstock 10 and scion 20 are joined and wrapped, it can ensure that the cambium alignment range of the rootstock 10 and scion 20 reaches more than 60%. Therefore, it is suitable for grafting multiple peonies, with high grafting efficiency and a high survival rate.

[0054] Understandably, when cutting and wrapping the rootstock 10 and scion 20, the operator can hold the rootstock 10 and scion 20 by hand and make minor adjustments to their positions to maximize the alignment range of the cambium layers of the rootstock 10 and scion 20, thereby improving the survival rate of peony grafting.

[0055] Among them, hemp rope 32 is made of cotton and linen, which can be gradually degraded by microorganisms in the natural environment and will not cause long-term pollution to the environment.

[0056] Reference Figure 4 and Figure 5 The support 1 and the slide 21 are arranged at intervals to form a space between the slide 21 and the support 1 for placing the rootstock 10 or the scion 20. The blade assembly 22 is connected to the slide 21 and is located between the support 1 and the slide 21. The slide 21 and the support 1 are moved relative to each other, and the blade assembly 22 can be used to cut the rootstock 10 or the scion 20.

[0057] The slide 21 has a rectangular frame outline. Four sets of guide components 4 are provided between the support 1 and the slide 21, and the four sets of guide components 4 are respectively arranged at the four corners of the slide 21. The guide components 4 include guide rods 41, guide sleeves 42 and springs (not shown in the figure). The guide sleeves 42 are fixedly connected to the support 1, and the guide rods 41 are fixedly connected to the slide 21. The guide rods 41 slide through the guide sleeves 42. The four sets of guide components 4 ensure the stability of the relative sliding between the slide 21 and the support 1. The spring is located inside the guide sleeves 42. One end of the spring is connected to the bottom wall of the guide sleeves 42, and the other end is connected to the end wall of the guide rods 41. When the slide 21 and the support 1 are moved relative to each other, the spring is compressed. After the blade assembly 22 has finished cutting the rootstock 10 or scion 20, under the action of the spring force, the guide rods 41 and guide sleeves 42 move away from each other and return to their original positions, thereby allowing the slide 21 and the support 1 to return to their original positions, so as to form a space between them for placing the rootstock 10 or scion 20, so that the next cutting can be carried out.

[0058] The bandaging device has a length direction and a width direction that are perpendicular to each other. When the rootstock 10 or scion 20 is placed on the support plate 11, the length direction of the rootstock 10 and scion 20 is consistent with the length direction of the bandaging device.

[0059] The support 1 and the slide 21 are equipped with two sets of force-applying components. The two sets of force-applying components are arranged opposite to each other on both sides of the slide 21 along the width direction of the slide 21. The force-applying components include two grips 5, which are fixedly connected to the slide 21 and the support 1 respectively. When cutting the rootstock 10 or the scion 20, the operator holds the two sets of force-applying components with both hands. The two sets of grips 5 apply a force that brings the slide 21 and the support 1 closer to each other, which can realize the cutting of the rootstock 10 or the scion 20. The operation is relatively convenient.

[0060] Reference Figure 4 and Figure 5The support plate 11 includes a base plate and two V-shaped side plates. The rootstock 10 or scion 20 is placed on the support plate 11. The two side plates of the support plate 11 provide stable support for the rootstock 10 or scion 20 and can accommodate rootstocks 10 or scions 20 of different diameters. There are two support plates 11: a first support plate 111 and a second support plate 112. The first support plate 111 and the second support plate 112 are arranged at intervals along the length of the support 1. The first support plate 111 supports the rootstock 10, and the second support plate 112 supports the scion 20. The rootstock 10 is placed on the first support plate 111, and the blade assembly 22 is used to cut the rootstock 10 to form a first incision. The scion 20 is placed on the second support plate 112, and the blade assembly 22 is used to cut the scion 20 to form a second incision.

[0061] The support plate 11 is slidably connected to the bracket 1 along the width direction of the bracket 1. The bottom of the support plate 11 is provided with a slider. The bracket 1 has a groove 121 for the slider to slide. The bracket 1 includes two extensions 12 extending along its width direction. The groove 121 extends to the extensions 12 so that the first support plate 111 and the second support plate 112 can slide outward along the width direction of the bracket 1 to the outside of the carriage 21.

[0062] The reel 31 of the wrapping assembly 3 is mounted on the bracket 1 near the extension 12 via a support. After the rootstock 10 and scion 20 are cut in sequence, the rootstock 10 and scion 20 are removed from the support plate 11, and the two support plates 11 are slid to the extension 12. Then the rootstock 10 and scion 20 are placed on the two support plates 11 respectively, and the first cut and the second cut are aligned. The operator can then pull out the hemp rope 32 on the reel 31 to wrap the rootstock 10 and scion 20. The wrapping operation is relatively convenient.

[0063] Reference Figures 6 to 9 To form the three types of peony grafting cuts mentioned above, the blade assembly 22 includes a longitudinal cutter 221 and two transverse cutters. The longitudinal cutter 221 is rotatably connected to the slide 21, and the two transverse cutters are parallel to each other, namely the first transverse cutter 222 and the second transverse cutter 223. The first transverse cutter 222 is arranged near the first support plate 111, and the second transverse cutter 223 is arranged near the second support plate 112. The first transverse cutter 222 and the second transverse cutter 223 are respectively located on both sides of the longitudinal cutter 221 and hinged to the longitudinal cutter 221, thereby forming a "Z"-shaped blade assembly 22. The longitudinal cutter 221 is used to form the first longitudinal section 102 and the second longitudinal section 202, and the transverse cutters are used to form the first transverse section 103 and the second transverse section 203. Rotating the longitudinal cutter 221 can adjust the angle of the longitudinal cutter 221, thereby adjusting the tilt angle of the first longitudinal section 102 and the second longitudinal section 202.

[0064] Reference Figure 6 The peony grafting and wrapping device also includes a limiting rod 6, which includes a connecting part 61 and two rod parts 62. The connecting part 61 is slidably engaged with the second transverse cutting blade 223, and the two rod parts 62 are respectively arranged on both sides of the second transverse cutting blade 223. The rod parts 62 are rotatably connected to the connecting part 61. The distance between the connecting part 61 and the transverse cutting blade is adjusted to a preset size, and the rod parts 62 are rotated to be perpendicular to the length direction of the rootstock 10. By fitting the limiting rod 6 against the side of the rootstock 10, the size of the first transverse section 103 can be limited. By fitting the limiting rod 6 against the side of the scion 20, the size of the second transverse section 203 can be limited. In addition, after the position of the rootstock 10 or the scion 20 is adjusted, the limiting rod 6 can be rotated to tilt it, preventing the blade assembly 22 from colliding with the support 1 when it moves towards the support 1.

[0065] Reference Figure 6 and Figure 7 When making the first cut of the first type, first adjust the distance between the limiting rod 6 and the longitudinal cutting blade 221 to the preset distance (the preset distance is equal to the length of the line segment of the first end face 101 of the rootstock 10 on the first projection plane after cutting), place the rootstock 10 on the first support plate 111, and align the first end face 101 of the rootstock 10 with the side of the second transverse cutting blade 223 facing the longitudinal cutting blade 221. At the same time, adjust the position of the first support plate 111 so that the side of the rootstock 10 fits against the limiting rod 6. Then control the slide 21 and the bracket 1 to move closer to each other, and cut the first cut body on the rootstock 10 through the longitudinal cutting blade 221 and the first transverse cutting blade 222 to form the first cut. Then remove the cut rootstock 10.

[0066] When making the second cut of the first type, the scion 20 is placed on the first support plate 111, and the scion 20 can be cut in the same way to form the second cut of the first type.

[0067] Reference Figure 8 When making the first cut of the third type, first adjust the distance between the limiting rod 6 and the longitudinal cutting blade 221 to the preset distance (the preset distance is equal to the length of the line segment of the first end face 101 of the rootstock 10 on the first projection plane after cutting). Then place the rootstock 10 on the first support plate 111 and align the first end face 101 of the rootstock 10 with the side of the second transverse cutting blade 223 facing the longitudinal cutting blade 221. At the same time, adjust the position of the first support plate 111 so that the side of the rootstock 10 fits against the limiting rod 6. Then control the slide 21 and the bracket 1 to move closer to each other. The first cut body is cut off on the rootstock 10 by the longitudinal cutting blade 221 and the first transverse cutting blade 222, thereby forming the first cut. Then remove the cut rootstock 10.

[0068] Reference Figure 9When making the second cut of the third type, the scion 20 is placed on the second support plate 112 and the second end face 201 of the scion 20 is aligned with the side of the first transverse cutter 222 facing the longitudinal cutter 221. At the same time, the position of the second support plate 112 is adjusted so that the side of the scion 20 is in contact with the limiting rod 6. Then, the slide 21 and the bracket 1 are controlled to move closer to each other. The second cut is cut off on the scion 20 by the longitudinal cutter 221 and the second transverse cutter 223, thereby forming the second cut.

[0069] Therefore, under the action of the limiting rod 6, the projection of the first end face 101 on the first projection plane and the projection of the second cross section 203 on the second projection plane are of equal length; when the rootstock 10 and the scion 20 are grafted, the first longitudinal section 102 and the second longitudinal section 202 are attached, the first end face 101 and the second cross section 203 are attached, and at the same time, the rootstock 10 and the scion 20 are flush on one side, so as to ensure that the alignment range of the cambium of the rootstock 10 and the scion 20 is not less than 60%, thus ensuring the survival rate of peony grafting.

[0070] Similarly, when making the second type of peony grafting incision, simply adjust the angle between the longitudinal cutter 221 and the transverse cutter to 90°.

[0071] Reference Figure 5 and Figure 6 A rotating shaft 211 is rotatably connected to the carriage 21. The end of the rotating shaft 211 closest to the longitudinal cutter 221 has a grooved plate 212 with a U-shaped groove. The longitudinal cutter 221 is engaged with the grooved plate 212 and is detachably connected via a bolt and nut assembly. Therefore, controlling the rotation of the rotating shaft 211 controls the rotation of the longitudinal cutter 221, thereby adjusting the tilt angle of the longitudinal cutter 221. A knob 213 is connected to the end of the rotating shaft 211 furthest from the longitudinal cutter 221; rotating the knob 213 controls the rotation of the rotating shaft 211.

[0072] Reference Figure 5 The carriage 21 is equipped with a protractor 214, which has scale lines arranged circumferentially along the rotating shaft 211. A pointer 2111 is fixedly connected to the rotating shaft 211. The tilt angle of the longitudinal cutter 221 can be determined by the position of the pointer 2111 on the protractor 214, which makes it easier for the operator to accurately control the angle of the first cut and the second cut.

[0073] Reference Figure 8 and Figure 9To ensure that the first cross-section 103 formed by the first cross-cutting blade 222 on the rootstock 10 is perpendicular to the length direction of the rootstock 10, and the second cross-section 203 formed by the second cross-cutting blade 223 on the scion 20 is perpendicular to the length direction of the scion 20, two limiting strips 7 are provided on the slide 21. The limiting strips 7 extend along the width direction of the slide 21 and slide along the length direction of the slide 21. The two limiting strips 7 are arranged close to the first cross-cutting blade 222 and the second cross-cutting blade 223, respectively. Thus, as long as the first cross-cutting blade 222 and the second cross-cutting blade 223 are respectively attached to the two limiting strips 7, it is possible to ensure that the first cross-cutting blade 222 is perpendicular to the length direction of the rootstock 10 and the second cross-cutting blade 223 is perpendicular to the length direction of the rootstock 10.

[0074] It is known that, depending on the type of scion 20, peony grafting methods include two types: branch grafting and bud grafting. The peony grafting wrapping device of this application embodiment is mainly applicable to branch grafting in peony grafting methods. In other embodiments, by changing the blade assembly 22, the peony grafting wrapping device can also cut a small piece of bark at an appropriate position on the rootstock 10, form a fixed-size incision on the rootstock 10, and insert the bud of the scion 20 into the incision, thus making it applicable to bud grafting in peony grafting methods.

[0075] This application also discloses a method for wrapping peony grafting, using the aforementioned peony grafting wrapping device. Taking the third type of peony grafting incision as an example, the peony grafting wrapping method of this application includes the following steps:

[0076] S1: Adjust the distance between the limit rod 6 and the longitudinal cutter 221 to the preset distance;

[0077] S2: Place the rootstock 10 on the first support plate 111 and align the first end face 101 of the rootstock 10 with the side of the second cross-cutting blade 223 facing the longitudinal cutting blade 221. At the same time, adjust the position of the first support plate 111 so that the side of the rootstock 10 fits against the limiting rod 6.

[0078] S3: Using the handle 5, control the slide 21 and the support 1 to move closer together, and use the longitudinal cutter 221 and the first transverse cutter 222 to cut the first cut body on the rootstock 10, thereby forming the first incision, and then remove the cut rootstock 10;

[0079] S4: Place the scion 20 on the second support plate 112 and align the second end face 201 of the scion 20 with the side of the first transverse cutter 222 facing the longitudinal cutter 221. At the same time, adjust the position of the second support plate 112 so that the side of the scion 20 fits against the limiting rod 6.

[0080] S5: Using the grip 5, control the slide 21 and the support 1 to move closer together, and use the longitudinal cutter 221 and the second transverse cutter 223 to cut the second cut body on the scion 20, thereby forming the second incision, and then remove the cut scion 20;

[0081] S6: Slide the first support plate 111 and the second support plate 112 to the extension 12, and place the rootstock 10 and the scion 20 on the first support plate 111 and the second support plate 112 respectively, and align the first cut and the second cut.

[0082] S7: Pull out the hemp rope 32 on the reel 31 and use the hemp rope 32 to wrap the rootstock 10 and scion 20 to complete the wrapping of the rootstock 10 and scion 20. At this point, the peony grafting is complete.

[0083] It is understandable that the above description of the peony grafting and wrapping device also applies to this peony grafting and wrapping method, and will not be repeated here.

[0084] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
