BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graft holder for fruit and vegetables.

[0002]

2. Description of the Related Art Conventionally, in crops such as Solanaceae and Cucurbitaceae, in order to prevent diseases caused by continuous cropping and soil-borne diseases, rootstocks having strong resistance to these crops have been used to graft scion. It has become popular.

The conventional graft-holding method uses a clip, which is a miniaturized version of domestic scissors, as a holder, but this method uses half of the surface area obtained by cutting the hypocotyl of a crop.
Since only about a half of them are retained, about 1/2 of them are exposed. Therefore, disease bacteria can easily infiltrate through the exposed parts, and since half of them are not retained, the success rate of grafting (the survival rate) ) 60-70% efficiency is very bad,
Further, after graft grafting, there are various drawbacks such as the time and effort required to remove the clip.

As another graft holding method, FIG.
As shown in the side view of (a) and the plan view of (b), the inlet part has a trumpet shape and is arranged in the longitudinal direction of the tubular main body 1 so that the cut rootstock and the scion can be easily inserted into the pipe. A cut holder 2 may be used, but if this holder 2 is attached to a graft part and then watered, water will accumulate in the trumpet part 3 and disease germs can easily infiltrate from this part. Is required. Further, since the inner diameter of the tubular body 1 is constant, several kinds of inner diameter holders 2 must be prepared each time the inner diameter changes. That is, when a rootstock or a scion thicker than the inner diameter is forcibly inserted, the cutting portion 4 opens, the grafted portion is exposed from here, and the disease bacteria 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.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and provides a graft holder which is resistant to invasion of disease bacteria, hassle-free, and can be quickly mounted.

[0006]

[Means and Actions for Solving the Problems] The present invention provides a longitudinal support for wrapping and tightening a portion where a rootstock and a scion are butted against each other in an arrangement such that the axial direction of the grafted portion is aligned with the surroundings. Of the flexible tubular body, the tubular body has a portion that is cut from one end side toward the other end side in the longitudinal direction, and the cut portion has the opposite edges thereof. It is characterized in that the grafts are held in a state of overlapping each other.

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 with each other, the graft portion can be held in an unexposed state. Hateful. In addition, the tubular body is provided with an inclination that matches the angle of the grafted portion, the overlapping portion of the cutting portion is thinly formed, and a support portion for the tubular body is separately provided, It is designed to be easily and surely attached to the graft.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the structure of the holder of this embodiment.
1A is a side view, FIG. 1B is a side view seen from the opposite side, FIG. 1C is a front view, and FIG. 1D is a sectional view.

The holder 11 is made of a transparent soft material.
The part that is made up of, and joins the rootstock and the scion with each other,
It has a long cylindrical main body 12 which is wrapped around in an arrangement such that the axial direction of the grafted portion is aligned with the surrounding portion and is supported so as to be tightened. The cylindrical main body 12 has its one end side to the other end in the longitudinal direction. Part 1 cut towards the side
3, this cutting portion 13 has its opposite edge 12a,
12b holds the graft in a state where the grafts 12b overlap each other .

Both end faces of the tubular body 12 (may be one end face)
Is cut and formed so as to have an angle d of 20 to 35 degrees with respect to the vertical surface 14 with respect to the axis of the cylindrical main body 12, as shown in FIG. Further, the opposing edge portions 12a and 12b of the cylindrical main body 12 have a shape in which the wall thickness gradually decreases as they approach the edge.

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. 1A, a mark 16 is provided near the center of the main body 12 in the longitudinal direction, which serves 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 11 between the rootstock 21 and the scion 22 is held by the holder 11.
(B) is a diagram showing a state before the rootstock 21 and the scion 22 are butted against each other.

That is, the holder is made of a soft material such as vinyl chloride which is UV-disintegratable, and has a facing edge portion 12.
Since a and 12b have a double overlapping shape,
Hypocotyls 21a, 22 of rootstock and scion to be inserted into the cylinder body 12
The inner diameter of the main body 12 expands and contracts according to the size of the diameter a (1.5 to 2.5 mm), and the joint portion of the graft is connected to the main body 12
Tighten from around with.

At this time, since the main body 12 has an expandable inner diameter, the tying pressure is constant, facilitating the living, and the opposing edges 12a and 12b are overlapped.
Even if the diameters of the hypocotyls 21a and 22b are changed, the joint portion of the graft is not exposed, and thus the invasion of disease fungi can be prevented.

In the case of, for example, tomatoes among fruits and vegetables, it is said that it is preferable to graft with a hypocotyl diameter of about 2 mm, and both the hypocotyl of the rootstock and the hypocotyl of the scion are 2 mm. This is the best condition, but in reality, there are differences in the degree of solidification of each species, with rootstocks of 2.1 mm and spikes of 1.
There is a difference of about 0.2 mm such as 9 mm.
When grafting seedlings with this difference, it is essential to tie the entire circumference of the hypocotyl with constant pressure. On the other hand, in the case of cucumber, the diameter of the hypocotyl is 2.2 m.
m is the best, but even if there are variations in the diameters of the hypocotyls of the scion and rootstock, the inner diameter of the tubular body 12 can be expanded and contracted as described above. Not only tomatoes, tomatoes and cucumbers, but also to several kinds of seedlings such as eggplant, watermelon and melon can be grafted well.

The angle d in FIG. 1C will be described. Usually, when the cutting angle of the graft 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 the hypocotyl cutting as a target is included, a considerable skill is required for cutting the hypocotyl.

Therefore, the angle d of the cylindrical body 12 of the present invention is
It is suitable as a ruler for cutting hypocotyls. For example, in the case of a rootstock, the main body 12 is parallel to the rootstock, and
It may be cut with a razor according to the inclination of the end face. At this time, if the rootstock is pressed against the support portion 15 in parallel with the rootstock to cut the rootstock, positional deviation between the main body 12 and the rootstock 22 is extremely unlikely to occur, which is convenient. Regarding the spikes, for example, if the end face of the main 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 2 as described above.
This is because it becomes 0 to 35 degrees.

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

Further, as shown in FIG. 1 (a), the cylindrical main body 1
Marks 16 near the center of 2 corresponding to the joints of the graft
With the mark, since the main body 12 is transparent, the end face of the scion and the end face of the rootstock inserted into the main body 12 can be easily marked 16
The edges of both trees will inevitably coincide. 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 to work quickly.

Further, since the support portion 15 is attached, the main body 12 can be supported without touching the main body 12, and thus the main body 1 can be supported.
It is possible to keep the inner diameter wide without holding the 2 by hand and narrowing the inner diameter of the main body 12,
It becomes easier to put the scion and rootstock inside. Moreover, the support portion 15
Is integrally formed in the longitudinal direction of the main body 12, so that it can be formed by an extruder together with the main body 12, and thus the main holder 11
It is also suitable for mass production. Further, the holder 11 is
Unlike conventional holders that use clips for grafting, it can be left alone because it naturally disintegrates, saving labor.

The present invention is not limited to the above embodiment, but 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 soft synthetic resin, synthetic rubber, and raw rubber can be used. Further, although the case where the extruder is used to manufacture the holder 11 has been described above, 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. Also in the example,
As shown in FIG. 1, the cutting portions 12 a, 12 of the tubular main body 12
Although b is made thinner as it goes in the direction of its edge, it may be of a constant thickness over the entire circumference, as shown in the cross section of FIG. 3, for example.

[0022]

As described above, according to the present invention, it is possible to provide a graft holder which is advantageous in that it is difficult for germs to invade, labor is easy, and it can be quickly mounted.
