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

[0003] At present, peony grafting is a manual operation. The operator uses a blade to make an incision at an appropriate position on the rootstock, then cuts the scion into a wedge shape and inserts it into the incision, and finally ties the scion and the rootstock together. Since the operator usually cuts the rootstock and scion based on experience, the incision angles and sizes on the scion and the rootstock have a certain randomness. When the scion is inserted into the incision of the rootstock, it is difficult to ensure the alignment range of the cambium of the scion and the cambium of the rootstock, resulting in difficulty in controlling the grafting survival rate.

[0041] The following is combined with Figure 1-9 This application is described in further detail.

[0042] The present application embodiment discloses a peony grafting incision. 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 arranged toward the scion 20, the first end face 101 is perpendicular to the length direction of the rootstock 10, the first incision has a first longitudinal section 102, the first longitudinal section 102 forms a first angle α with the first end face 101, the scion 20 has a second end face 201 arranged toward the rootstock 10, the second end face 201 is perpendicular to the length direction of the scion 20, the second incision has a second longitudinal section 202, the second longitudinal section 202 forms a second angle with the second end face 201 Angle β, the first angle is equal to the second angle; 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 endpoint 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 endpoint arranged away from the second end face 201, and the distance between the first endpoint and the first end face 101 is equal to the distance between the second endpoint and the second end face 201.

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

[0044] The peony grafting incision of the embodiment of the present application can limit the angles of the first incision and the second incision to be equal and the sizes to match by limiting the first angle to be equal to the second angle and 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. When the first incision of the rootstock 10 and the second incision of the scion 20 are aligned, it can ensure that the alignment range of the cambium of the rootstock 10 and the scion 20 is not less than 60%, thereby controlling the survival rate of the peony grafting at a high level.

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

[0046] The peony grafting incisions in the embodiments of the present application include three types. To facilitate the description of the three types of peony grafting incisions, the portion cut off from the rootstock 10 is named the first cut-off body, and the portion cut off from the scion 20 is named the second cut-off body. The first incision is formed by cutting off the first cut-off body from the rootstock 10, and the second incision is formed by cutting off the second cut-off body from the scion 20.

[0047] Reference Figure 1, which is the first type of peony grafting incision, the projection of the first cut body on the first projection plane and the projection of the second cut body on the second projection plane are both triangular, and the sizes and angles of the two are equal, the first longitudinal section 102 and the second longitudinal section 202 are both arranged obtusely, so that the first angle α and the second angle β are both obtuse angles, and the first angle α and the second angle β are 100° to 130°. In this way, the area of ​​the first longitudinal section 102 and the second longitudinal section 202 can be increased, and when the stock 10 and the scion 20 are grafted, the contact area of ​​the first longitudinal section 102 and the second longitudinal section 202 is larger, and by adjusting the relative positions of the stock 10 and the scion 20, the cambium of the two can be aligned in a larger range, thereby improving the survival rate of peony grafting.

[0048] Reference Figure 2 , which is the second type of peony grafting incision, the projection of the first cut body on the first projection plane and the projection of the second cut body on the second projection plane are both rectangular, the first angle α and the second 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 cross 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 cross section 203 arranged parallel to the second end face 201; 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 both line segments and the lengths of the two are equal. Thus, when the rootstock 10 and the scion 20 are grafted, the first longitudinal section 102 fits with the second longitudinal section 202, the first end face 101 fits with the second cross section 203, and one side of the rootstock 10 and the scion 20 are flush, thereby further increasing the alignment range of the cambium of the rootstock 10 and the scion 20 and improving the survival rate of the peony grafting.

[0049] In addition, since the first longitudinal section 102 and the first cross section 103 are perpendicular to each other, and the second longitudinal section 202 and the second cross section 203 are perpendicular to each other, the relative position of the rootstock 10 and the scion 20 can be limited. When the rootstock 10 and the scion 20 are wrapped, the relative position of the two is more stable, thereby improving the convenience of the wrapping operation during the peony grafting process.

[0050] Reference Figure 3, which is the third type of peony grafting incision. The third type of peony grafting incision is similar to the second type of peony grafting incision. The difference between the two is that the projection of the first cut body on the first projection plane and the projection of the second cut body on the second projection plane are both right-angled trapezoids, that is, the first angle α and the second angle β are both obtuse angles, and the first angle α and the second angle β are 100° to 130°. Therefore, when the stock 10 and the scion 20 are grafted, the first longitudinal section 102 and the second longitudinal section 202 have a larger contact area, which can ensure that the relative position of the stock 10 and the scion 20 is stable while improving the alignment range of the cambium of the two, thereby further improving the survival rate of the peony grafting.

[0051] The present application also discloses a peony grafting and wrapping device, referring to Figure 4 and Figure 5 The peony grafting and wrapping device includes a bracket 1, a cutting assembly 2 and a wrapping assembly 3; the bracket 1 includes a support plate 11 for supporting a rootstock 10 or a scion 20; the cutting assembly 2 includes a slide 21 and a blade group 22, the slide 21 is slidably connected to the bracket 1, the blade group 22 is connected to the slide 21, and the blade group 22 has a blade arranged toward the support plate 11; the wrapping assembly 3 includes a reel 31 and a hemp rope 32, the reel 31 is connected to the bracket 1, the hemp rope 32 is wound around the reel 31, and the hemp rope 32 is used to wrap around the rootstock 10 and the scion 20.

[0052] The rootstock 10 or the scion 20 is placed on the support plate 11, and the slide 21 is controlled to drive the blade group 22 to move toward the support plate 11, so that the rootstock 10 can be cut to form the above-mentioned first incision, and the scion 20 can be cut to form the above-mentioned second incision; then the rootstock 10 and the scion 20 are aligned so that the first longitudinal section 102 and the second longitudinal section 202 are in contact with each other; then the hemp rope 32 on the reel 31 is used to wrap the rootstock 10 and the scion 20 to complete the wrapping of the rootstock 10 and the scion 20, so as to realize the peony grafting.

[0053] The peony grafting and wrapping device of the embodiment of the present application cuts the rootstock 10 and the scion 20 through the blade group 22, and can control the angle and size of the first incision and the second incision to match each other. When the rootstock 10 and the scion 20 are docked and wrapped, it can ensure that the cambium alignment range of the rootstock 10 and the scion 20 reaches more than 60%, so that it is suitable for grafting multiple peonies, the grafting efficiency is high, and the survival rate can be controlled at a high level.

[0054] It is understandable that when cutting and wrapping the rootstock 10 and the scion 20, the operator can hold the rootstock 10 and the scion 20 by hand and fine-tune the positions of the rootstock 10 and the scion 20 to maximize the alignment range of the cambium of the rootstock 10 and the scion 20, thereby improving the survival rate of peony grafting.

[0055] The 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 group 22 is connected to the slide 21 and is arranged between the support 1 and the slide 21. The slide 21 and the support 1 are moved relative to each other, and the rootstock 10 or the scion 20 can be cut by the blade group 22.

[0057] The outer contour of the slide 21 is a rectangular frame. Four sets of guide components 4 are arranged between the bracket 1 and the slide 21. The four sets of guide components 4 are arranged at the four corners of the slide 21 respectively. The guide component 4 includes a guide rod 41, a guide sleeve 42 and a spring (not shown in the figure). The guide sleeve 42 is fixedly connected to the bracket 1, and the guide rod 41 is fixedly connected to the slide 21. The guide rod 41 is slidably inserted into the guide sleeve 42. The stability of the relative sliding between the slide 21 and the bracket 1 is ensured by the four sets of guide components 4. The spring is arranged in the guide sleeve 42, one end of the spring is connected to the bottom wall of the guide sleeve 42, and the other end is connected to the end wall of the guide rod 41. When the slide 21 and the bracket 1 are relatively moved, the spring is compressed. When the blade group 22 completes the cutting of the stock 10 or the scion 20, under the elastic force of the spring, the guide rod 41 and the guide sleeve 42 are relatively separated and reset, so that the slide 21 and the bracket 1 are reset to form a space for placing the stock 10 or the scion 20 between the two, and the next cutting can be performed.

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

[0059] Two groups of force-applying components are provided on the bracket 1 and the slide 21. The two groups of force-applying components are arranged relatively on both sides of the slide 21 along the width direction of the slide 21. The force-applying components include two gripping rods 5. The two gripping rods 5 are fixedly connected to the slide 21 and the bracket 1 respectively. When cutting the rootstock 10 or the scion 20, the operator holds the two groups of force-applying components with both hands respectively, and applies a force to the slide 21 and the bracket 1 to move closer to each other through the two groups of gripping rods 5, so as to achieve cutting of the rootstock 10 or the scion 20, and the operation is relatively convenient.

[0060] Reference Figure 4 and Figure 5The support plate 11 includes a bottom plate and two side plates arranged in a V shape. The stock 10 or the scion 20 is placed on the support plate 11. The two side plates of the support plate 11 can provide stable support for the stock 10 or the scion 20, and can adapt to stock 10 or scion 20 of different diameters. There are two support plates 11, namely 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 direction of the support 1. The first support plate 111 is used to support the stock 10, and the second support plate 112 is used to support the scion 20. The stock 10 is placed on the first support plate 111, and the blade group 22 is used to cut the stock 10 to form a first incision. The scion 20 is placed on the second support plate 112, and the blade group 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. A slider is provided at the bottom of the support plate 11, and the bracket 1 has a slide groove 121 for the slider to slide. The bracket 1 includes two extensions 12 extending along its width direction, and the slide groove 121 extends to the extension part 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 slide 21.

[0062] The reel 31 of the wrapping assembly 3 is installed on one side of the bracket 1 close to the extension part 12 through a support. After the cutting of the rootstock 10 and the scion 20 is completed in sequence, the rootstock 10 and the scion 20 are removed from the support plate 11, and the two support plates 11 are slid to the extension part 12. Then, the rootstock 10 and the scion 20 are placed on the two support plates 11 respectively, and the first incision and the second incision are aligned. The operator pulls out the hemp rope 32 on the reel 31 to wrap the rootstock 10 and the scion 20, and the wrapping operation is relatively convenient.

[0063] Reference Figures 6 to 9 In order to form the above three types of peony grafting incisions, the blade group 22 includes a longitudinal cutting knife 221 and two cross-cutting knives. The longitudinal cutting knife 221 is rotatably connected to the slide 21. The two cross-cutting knives are parallel to each other, namely a first cross-cutting knife 222 and a second cross-cutting knife 223. The first cross-cutting knife 222 is arranged close to the first supporting plate 111, and the second cross-cutting knife 223 is arranged close to the second supporting plate 112; the first cross-cutting knife 222 and the second cross-cutting knife 223 are respectively arranged on both sides of the longitudinal cutting knife 221 and are hinged to the longitudinal cutting knife 221, thereby forming a "Z"-shaped blade group 22; wherein the longitudinal cutting knife 221 is used to form the first longitudinal section 102 and the second longitudinal section 202, and the cross-cutting knife is used to form the first cross-section 103 and the second cross-section 203. Rotating the longitudinal cutting knife 221 can adjust the angle of the longitudinal cutting knife 221, thereby adjusting the inclination 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 portion 61 and two rod portions 62. The connecting portion 61 and the second cross-cutting knife 223 can be slidably engaged, and the two rod portions 62 are respectively arranged on both sides of the second cross-cutting knife 223, and the rod portion 62 is rotatably connected to the connecting portion 61; the distance between the connecting portion 61 and the side cutter is adjusted to a preset size, and the rod portion 62 is rotated to be perpendicular to the length direction of the stock 10, and the size of the first cross-section 103 can be limited by the side of the limiting rod 6 and the stock 10. The size of the second cross-section 203 can be limited by the side of the limiting rod 6 and the scion 20. In addition, after the position adjustment of the stock 10 or the scion 20 is completed, the limiting rod 6 can be rotated to tilt it to prevent the blade group 22 from colliding with the bracket 1 when moving in the direction of the bracket 1.

[0065] Reference Figure 6 and Figure 7 When cutting the first type of first incision, first adjust the spacing between the limit rod 6 and the longitudinal cutting knife 221 to a preset spacing (the preset spacing is equal to the length of the linear projection 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 knife 223 facing the longitudinal cutting knife 221, and at the same time adjust the position of the first support plate 111 so that the side of the rootstock 10 is in contact with the limit rod 6, and then control the slide 21 and the bracket 1 to be relatively close, and cut the first cut body on the rootstock 10 by the longitudinal cutting knife 221 and the first transverse cutting knife 222, thereby forming a first incision, and then remove the cut rootstock 10.

[0066] When cutting the second incision of the first type, the scion 20 is placed on the first supporting plate 111, and the scion 20 can be cut in the same manner to form the second incision of the first type.

[0067] Reference Figure 8 When cutting the first incision of the third type, first adjust the spacing between the limit rod 6 and the longitudinal cutting knife 221 to a preset spacing (the preset spacing is equal to the length of the linear projection 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 knife 223 facing the longitudinal cutting knife 221, and at the same time adjust the position of the first support plate 111 so that the side of the rootstock 10 is in contact with the limit rod 6, and then control the slide 21 and the bracket 1 to be relatively close, and cut the first cut body on the rootstock 10 by the longitudinal cutting knife 221 and the first transverse cutting knife 222, thereby forming a first incision, and then remove the cut rootstock 10.

[0068] Reference Fig. 9When cutting the second incision of the third type, the scion 20 is placed on the second supporting plate 112, and the second end face 201 of the scion 20 is aligned with the side of the first transverse cutting knife 222 facing the longitudinal cutting knife 221, and the position of the second supporting plate 112 is adjusted so that the side of the scion 20 is in contact with the limiting rod 6, and then the slide 21 and the bracket 1 are controlled to be relatively close, and the second cut body is cut off on the scion 20 by the longitudinal cutting knife 221 and the second transverse cutting knife 223, thereby forming a second incision.

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

[0070] Similarly, when cutting the second type of peony grafting incision, the angle between the longitudinal cutting knife 221 and the transverse cutting knife is adjusted to 90°.

[0071] Reference Figure 5 and Figure 6 The slide 21 is rotatably connected with a rotating shaft 211. A slot plate 212 having a U-shaped slot is provided at one end of the rotating shaft 211 close to the longitudinal cutting knife 221. The longitudinal cutting knife 221 is clamped with the slot plate 212 and is detachably connected via a bolt and nut assembly. Thus, controlling the rotation of the rotating shaft 211 can control the rotation of the longitudinal cutting knife 221, thereby adjusting the tilt angle of the longitudinal cutting knife 221. A knob 213 is connected to one end of the rotating shaft 211 away from the longitudinal cutting knife 221. Rotating the knob 213 can control the rotation of the rotating shaft 211.

[0072] Reference Figure 5 A protractor 214 is provided on the slide 21, and the protractor 214 has scale lines arranged along the circumference of the rotating shaft 211. A pointer 2111 is fixedly connected to the rotating shaft 211. The inclination angle of the longitudinal cutting knife 221 can be determined by the position of the pointer 2111 on the protractor 214, which is more conducive to the operator to accurately control the angles of the first incision and the second incision.

[0073] Reference Figure 8 and Fig. 9, to ensure that the first cross-section 103 formed by the first cross-cutter 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-cutter 223 on the scion 20 is perpendicular to the length direction of the scion 20; two limit strips 7 are provided on the slide 21, and the limit strips 7 extend along the width direction of the slide 21 and are slidably connected to the slide 21 along the length direction of the slide 21, and the two limit strips 7 are arranged close to the first cross-cutter 222 and the second cross-cutter 223 respectively; therefore, it is only necessary to ensure that the first cross-cutter 222 and the second cross-cutter 223 are respectively attached to the two limit strips 7, so as to ensure that the first cross-cutter 222 is perpendicular to the length direction of the rootstock 10, and the second cross-cutter 223 is perpendicular to the length direction of the rootstock 10.
