[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a holder for grafting of fruits and vegetables.

[0002]

[Prior Art]

 In the past, crops such as Solanaceae and Cucurbitaceae have been frequently used to graft scion with rootstocks that have strong resistance to continuous crop damage and soil-borne diseases in order to prevent them. Has become.

The conventional graft-holding method uses a clip, which is a miniaturized version of household scissors, as a holder, but this method holds only about 1/2 of the surface area obtained by cutting the hypocotyl of a crop. Since it is not exposed, about 1/2 of it is exposed, so that the fungus easily invades from the exposed part, and since it does not hold the whole, half grafting increases, and the success rate (grafting rate) of grafting 60 There were various drawbacks, such as a very low efficiency of ~ 70%, and the need to remove the clip after graft grafting.

As another graft holding method, as shown in the side view of FIG. 4 (a) and the plan view of FIG. 4 (b), an inlet part is provided so that a cut rootstock and a scion can be easily inserted into a pipe. A holder 2 which has a trumpet shape and is cut in the longitudinal direction of the cylindrical main body 1 is also conceivable. However, when this holder 2 is attached to a graft part and water is applied, water is collected in the trumpet part 3 from which the disease germs are collected. Since it is easy to infiltrate, it is necessary to take measures such as spraying Ozo water or medicine. Moreover, since the inner diameter of the tubular body 1 is constant, several types of inner diameter holders 2 must be prepared each time the inner diameter changes. That is, if a rootstock or a scion thicker than the inner diameter is forcibly inserted, the cutting portion 4 opens, the grafting portion is exposed from here, and the bacterium can easily enter there. Further, since the holder shown in FIG. 4 has a trumpet shape, it is difficult to manufacture it by extrusion molding, which is not suitable for mass production.

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and provides a graft holder that is resistant to the infestation of bacteria, hassle-free, and can be quickly mounted.

[0006]

[Means and actions for solving the problem]

 The present invention has a longitudinal flexible tubular body that wraps the portion where the rootstock and the scion are butted and grafted in such a way that the axial direction of the grafted portion is aligned with the surrounding portion and holds them so that they are tightened. The main body has a portion that is cut in the longitudinal direction from one end side to the other end side, and the cut portion holds the graft with its opposite edges overlapping each other. It is characterized in that

That is, according to the present invention, since the cut portion of the tubular body holds the graft portion with the opposite edges thereof overlapped, the graft portion can be held in an unexposed state. Is hard to enter. In addition, the tubular body is designed with an inclination that matches the angle of the graft, the thickness of the overlapping part of the cutting part is made thin, and the supporting part of the tubular body is provided separately. It is designed to be easily and surely attached to the graft.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1A and 1B show the structure of the holder of this embodiment, FIG. 1A is a side view, FIG. 1B is a side view seen from the opposite side, FIG. 1C is a front view, and FIG. d) is a sectional view.

This holder 11 is a long flexible tubular main body that supports the portion where the rootstock and the scion are butted against each other by wrapping them in such an arrangement that the axial direction of the portion to be grafted is matched with the surroundings. The tubular main body 12 has a portion 13 which is cut in the longitudinal direction from one end side to the other end side, and the cut portion 13 has the opposite edge portions 12a, 12b. The grafts are held so that they overlap each other.

As shown in FIG. 1C, both end surfaces (or one end surface) of the tubular body 12 have an angle d of 20 to 35 degrees with respect to a vertical surface 14 with respect to the axis of the tubular body 12. It is formed by cutting. Further, the facing edges 12a and 12b of the tubular body 12 have a shape in which the wall thickness gradually decreases as they approach the edges.

The cylindrical main body 12 has a main body supporting portion 15 formed so as to project therefrom. Here, the main body supporting portion 15 is formed in a direction along the longitudinal direction of the main body 12. As shown in FIG. 1 (a), a mark 16 is provided near the center of the main body 12 in the longitudinal direction as a guide for matching the position of the graft, that is, the joint between the rootstock and the scion.

FIG. 2A shows a state in which the graft portion of the rootstock 21 and the spike 22 is held by the holder 11, and FIG. 2B shows the rootstock 21 and the spike 22 butted against each other. It is a figure which shows the state before.

That is, the holder is made of a soft material such as vinyl chloride that is UV-disintegratable, and the opposite edges 12a and 12b have a double overlapping shape. Therefore, the holder is inserted into the tubular body 12. The inner diameter of the main body 12 expands and contracts in accordance with the diameter (1.5 to 2.5 mm) of the hypocotyls 21a, 22a of the rootstock and the scion, and the joint portion of the graft is surrounded by the main body 12 from the surroundings. Tighten to tighten.

At this time, since the inner diameter of the main body 12 is freely expandable and contractible, the conjugation pressure is constant, facilitating the attachment, and the opposing edges 12a and 12b are overlapped, so that the hypocotyls 21a and 22b are formed. Even if the diameter of the graft fluctuates, the joint part of the graft will not be exposed, and thus the invasion of fungi can be prevented.

In the case of, for example, tomato among fruit vegetables, it is said that grafting with a hypocotyl diameter of about 2 mm is preferable, and both the root axis hypocotyl and the scion hypocotyl are 2 mm. Is the best condition, but in reality, there is a difference in the degree of solidification that each species has, resulting in a difference of about 0.2 mm such as 2.1 mm for the rootstock and 1.9 mm for the scion. When grafting seedlings with this difference, it is essential to bind the entire circumference of the hypocotyl with constant pressure. On the other hand, in the case of cucumber, the hypocotyl diameter of about 2.2 mm is the best, but even if the hypocotyl diameter of the scion and rootstock varies, as described above, Since the inner diameter is flexible, one holder 11 can be used to graft tomatoes, cucumbers, eggplants, watermelons, melons, and other types of seedlings.

The angle d in FIG. 1C will be described. Usually, when the grafting angle is 20 to 35 degrees with respect to the plane perpendicular to the axis of the hypocotyl, the survival rate is high. On the other hand, since rootstocks are generally planted in pots, farmers cut the rootstocks with a razor by eye registration, and the spikelets are cut at appropriate points and cut on the board at the above angle. To do. The optimum value of this cutting angle is around 30 degrees, but since a hypocotyl cut for eye registration is included, considerable skill is required to cut the hypocotyl.

Therefore, the angle d of the tubular body 12 of the present invention is suitable as a ruler for cutting hypocotyls. For example, in the case of a rootstock, the main body 12 may be parallel to the rootstock, and the rootstock may be cut with a razor according to the inclination of the end surface of the main body 12. At this time, if the rootstock is pressed against the support portion 15 in a state of being parallel to this to cut the rootstock, a positional deviation between the main body 12 and the rootstock 22 is extremely unlikely to occur, which is convenient. As for the spikes, for example, if the end face of the body 12 at the angle d is drawn as a ruler on a plate for cutting the spikes, and the spikes are cut along this line, the spikes 21 and the rootstock 22 are separated. There is almost no gap on the joint surface of the graft, and the two are surely in close contact with each other. Therefore, there is a great effect that the survival rate can be greatly improved. The end face angle of the tubular body 12 of the present invention is set to 20 to 35 degrees because the cutting angle of the end face of the graft is 20 to 35 degrees as described above.

Further, since the wall thicknesses of the facing edges 12a, 12b of the cut portion become thinner toward the edge side, the force for tightening the scion and the rootstock is weakened accordingly, and thus these trees are attached to the main body 12 Easy to insert inside.

Further, as shown in FIG. 1 (a), if a mark 16 corresponding to the joint of the graft is provided near the center of the tubular body 12, the body 12 is transparent, It is possible to easily match the end faces of the scion and the rootstock inserted in the to the mark 16, and at this time, the end faces of both trees inevitably coincide with each other. For this reason, it is possible to obtain a graft that is firmly joined, and it is possible to quickly match the end faces of both trees, and work can be done quickly.

Further, since the support portion 15 is attached, the main body 12 can be supported without touching the main body 12, and therefore the inner diameter of the main body 12 is not narrowed by holding the main body 12 by hand. The inner diameter can be kept wide and the spikes and rootstocks can be easily stored inside. Moreover, since the supporting portion 15 is integrally formed in the longitudinal direction of the main body 12, it can be formed together with the main body 12 by an extruder, and is therefore suitable for mass production of the main holder 11. Further, unlike the conventional holder using the clip of the graft, the holder 11 can be left as it naturally disintegrates, so that the labor can be saved.

The present invention is not limited to the above-mentioned embodiment, and various applications are possible. For example, although disintegratable vinyl chloride is used as the material of the main body 12 in the embodiment, various other materials such as other flexible synthetic resin, synthetic rubber, and raw rubber can be used. Further, in the above description, the case where the extruder is used to manufacture the holder 11 has been described, but the holder 11 may be manufactured by molding. In this case, it is not suitable for mass production as compared with the case of manufacturing with an extruder, but there is an advantage that the mark 16 can be easily attached. Further, in the embodiment, as shown in FIG. 1, the cut portions 12a and 12b of the cylindrical main body 12 are made thinner toward the end edges thereof. However, for example, as shown in the cross section of FIG. The wall thickness may be constant.
