5 are joined together. Rootstock 25 and Hogi 26
As shown in FIG. 2, four holes on the peripheral surface
Are held between the surfaces 5, 6, 7, 8
Are held in a connected state.

As described above, the grafting device 1 always holds the rootstock 25 and the scion 26 at four positions even when the stem diameter changes, so that the rooting is reliably performed. In addition, stock 25 and scion 2
As shown in FIG. 6, even when the diameter increases from D1 to D2 with the growth of 6, the connecting portions 31, 3, 8
Rootstock 25 and Hogi 2 to spread around 2,33
4 are sandwiched by the surfaces 5, 6, 7, 8 of the insertion hole 3. Thus, this grafting device 1
Regardless of the thickness of the stock 25 and the scion 26, be sure to
Since the five portions are clamped so that the surfaces 5, 6, 7, and 8 are pressed toward the center, misalignment hardly occurs.

The grafting device 1 has a polygonal shape due to the elasticity of the connecting portion between the surfaces. That is, in the grafting device 1, the angle between the surfaces 5 and 6 is maintained by the elasticity of the connecting portion 31 between the surfaces 5 and 6, and the angle between the surfaces 6 and 7 is maintained by the connecting portion 32 between the surfaces 6 and 7. The angle between the surface 7 and the surface 8 is maintained by the connecting portion 33 between the surface 7 and the surface 8. Therefore, since the stock 25 and the scion 26 are sandwiched by the above-described elasticity, when the stock 25 and the scion 26 become thicker, the surfaces 5, 6, 6
7 and 8 are spread, but the surfaces 5, 6, 7, and 8 are not deformed, and even if deformed, the surfaces 5, 6, 7, and 8 are peripheral surfaces of the stock 25 and the scion 26. Of four places. Since the cut grooves 11 to 13 are provided in the connection portions 31 to 33, the surfaces 5, 6, 7, and 8 are easily spread.

In this type of grafting device, when the stock 25 and the scion 26 become thicker to some extent, the cracks open widely and come off naturally. However, the grafting device 1 has two surfaces 5 and 8 on both sides of the crack 10. Are formed in a semicircular shape so that they can be easily removed from the stock 25 and the scion 26.

The grafting device 21 is shown in FIGS.
As shown in (2), a configuration may be made up of two cylindrical holders 2 and 2 and a connecting portion 23 connecting the two holders 2 and 2. The two holders 2 and 2 and the connecting portion 23 are integrally formed of an elastic material having elasticity such as a soft synthetic resin material or a synthetic rubber, and a stock 25 and a scion 26 are provided inside the two holders 2 and 2. An insertion hole 3 to be inserted and connected is formed. The shape of the insertion hole 3 is as described above. In addition,
The fracture 10 is formed in the connection portion 30 at the position farthest from the connection portion 23.

The grafting device 21 can use the holders 2 one by one, as in the grafting device 1. As shown in FIG. 15, the insertion hole 3 of one of the holders 2 is placed on the ground. It can be inserted into the standing support rod 35, and the stock 25 and the scion 26 can be inserted into the other holding body 2 and grafted,
The support bar 35 can support the stock 25 and the scions 26. Further, by changing the size of both the insertion holes 3, 3, the applicable range of the stem diameter can be further expanded.

The outer shape of the holder 2 is not particularly limited, and is formed in a circular shape as shown in FIGS. 1 and 13, and as shown in FIGS. 16 and 17. 2
It goes without saying that the outer shape of a and 2b may be formed in a substantially rectangular shape, and the sizes of the insertion holes 3d and 3e of the holders 2a and 2b arranged on both sides may be changed. Absent. Also, as shown in FIG.
May be provided at a position close to the connecting portion 23.

[0024]

As described above, the first aspect of the present invention is as follows.
In the grafting device, an insertion hole for inserting and connecting a stock and a scion to the holder is formed, and the insertion hole is formed in a substantially polygonal cross-sectional shape by a plurality of surfaces extending in the longitudinal direction. Since the respective surfaces sandwich the rootstock and the scion, there is an effect that the rooting can be reliably performed as compared with the conventional grafting device that presses and holds the entire peripheral surface of the rootstock and the scion. In addition, since each surface presses the stock and the scion toward the center side, positioning is possible, and there is an effect that misalignment hardly occurs. In addition, the angle between each surface and each surface is determined by the connection between each surface and each surface. When the root becomes thicker as the stock and the scion grow, each surface expands around this connection, but this connection Since the cut groove is formed in the part, this spreading is performed smoothly, and there is no effect that the peripheral surfaces of the stock and scion are crimped and crimped unlike the conventional grafting device. There is.

The grafting device according to claims 2 and 3 of the present application is provided with two holders having the above-described effects, and can be adapted to grafts of various thicknesses by changing the size of both insertion holes. By attaching one of the holders to the support rod, there is an effect that the rootstock and the scion can be supported at the time of grafting with the other holder.

According to the grafting device of the present invention, since the number of the plurality of surfaces extending in the longitudinal direction is four and the cross-sectional shape of the insertion hole is substantially quadrangular, the molding is easy and the four surfaces are each formed. Is pressed so as to press the stock and the scion toward the center side, so that there is an effect that the misalignment hardly occurs.

In the grafting device according to the fifth aspect of the present invention, in addition to the above-described effects, the edges of both sides sandwiching the crack are formed in a substantially semicircular shape, so that the rootstock and the scion easily come off when they become thick. This has the effect.
