Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graft support used for grafting seedlings of fruit vegetables such as eggplant, tomato, and cucumber. More specifically, for example, when grafting fruit vegetables, rootstocks and scion of seedlings are used. The present invention relates to a graft support for attaching to a joint part of the.

[0002]

2. Description of the Related Art A conventional graft support for fruits and vegetables has been proposed in Japanese Utility Model Publication No. 4-6530. The graft support shown in this publication is composed of a synthetic resin elastic tubular body 20 provided with a vertical cut 22 extending from one end to the other end, and is elastic over the entire circumference of the graft joining portion 3 almost entirely. It has a diameter D enough to hold
The upper and lower end surfaces of the elastic tubular body 20 are inclined cut surfaces 23 and 24 corresponding to the inclined surfaces 4 and 5 of the cuts in the rootstock 1 and the scion 2 with respect to the axis of the elastic tubular body. .

[0003]

In grafting work of seedlings such as fruits and vegetables such as eggplant, tomato and cucumber, an inclined surface is provided at the cuts of the rootstock and the scion to widen the adhesion area between the two and establish the survival Was increasing the rate. Then, it was necessary to set the inclined surface of the cut provided on the seedling in a direction having an angle of 90 degrees with respect to the slit provided in the longitudinal direction of the elastic tubular body. In other words, if the slopes of the cuts of the rootstock and the scion are facing the installation direction of the slit, the scion easily separates from the slit due to its own weight and falls.

In order to solve this problem, in the above prior art, the upper and lower end surfaces of the tubular body 20 are cut in the same direction with respect to the axis of the tubular body 20 in the same direction as the inclined surface of the cut in the graft. The surfaces 23 and 24 are provided, and the orientation of the inclined surfaces of the cuts 4 and 5 of the graft is determined based on the direction of the cut surface.

However, the actual size of the tubular body of the graft support is about 6 mm in diameter and about 10 mm in length, which is extremely small, and the direction of the inclined cut surface of the end face of the tubular body is changed. Immediate visual recognition was a difficult task. It was also difficult to visually recognize the position of the slit-shaped notch 22.

In addition, when grafting fruits and vegetables, it is necessary to carry out grafting work of about 1,000 pieces per person per day, so quick work is required, and the inclination direction of the tubular body is instantaneously changed. It was not easy to visually recognize, and it was one of the causes of tired eyes of the operator. Therefore, there has been a demand for the development of a graft support that can easily and easily determine the installation direction of the inclined surface of the cut end of the graft.

Further, the tubular body 20 in the conventional graft supporting device is formed of a regular cylindrical tube having a constant wall thickness, and a seedling in the tubular body 22 grows or the diameter of the tubular body 20 is increased. When a sapling thicker than D is pushed into the cylinder, the notch 22 opens and a load is applied to the back part of the notch 22 that serves as a fulcrum, and since this fulcrum has a constant wall thickness, it can be said to be the fate of the resin Power gradually decreases. Therefore, there has been a strong demand for the development of a graft support capable of preventing a decrease in holding power and improving a survival rate.

[0008] In addition, a thin and thick variation inevitably occurs in the enlargement of the hypocotyl of the rootstock and the scion of the rootstock, and in the conventional regular cylindrical seedling insertion hole, there is a gap between the two and it is firmly held. There was a problem I could not have. Therefore, even if the growth conditions are different and the hypocotyl diameters of the rootstock and scion vary, it is strongly desired to develop a graft support that can be firmly held without floating. .

Furthermore, both the rootstock and the scion are very soft, and even if the material for the graft support is made of a resin as soft as possible, the seedling for inserting the rootstock and the scion into the seedling insertion hole is very good. There was a problem that the stems of the stalks were easily damaged. Therefore, it has been strongly desired to develop a graft support that does not damage the stem of the seedling even if the rootstock and the scion are thicker than the seedling insertion hole.

According to the present invention, when grafting vegetables such as eggplants, tomatoes and cucumbers, the installation direction of the slope of the cut edge of the graft is instantly and easily found, and the holding power of the seedling is enhanced. It is an object of the present invention to provide a graft support which can improve the survival rate, can be adapted to seedlings having different growth conditions, and can easily and easily perform grafting work without damaging the stems of the seedlings.

FIG. 2 shows a plan view of a graft supporting device including a tubular holding body according to an embodiment of the present invention. FIG. 3 shows a cross-sectional view of a graft supporting device composed of a tubular holding body according to an embodiment of the present invention as seen from a plane. FIG. 4 shows a front view of the graft support of FIG. FIG. 5 shows a front view of a state in which a seedling is inserted into the tubular holder. Figure 6
The top view of the graft support which consists of a cylindrical holding body is shown in FIG.

The graft support 1 of the present invention shown in FIGS. 1 to 6 is made of an elastic and flexible material such as soft rubber or soft synthetic resin, and has a seedling insertion hole 2 and a V that expands outward.
It is composed of a tubular holding body 3 having a V-shaped groove 4, and a slit 9 is formed at the top of the V-shaped groove 4 in the longitudinal direction of the holding body 3. On the opposite side of the slit 9 of the tubular holding body 3, a knob portion 1 including two protruding portions 12, 12.
1 is formed. In addition, the two protrusions 12, 1
An opening hole 13 is formed on the inner side of 2.

By forming a gripping portion 11 consisting of two projecting portions 12, 12 on the side opposite to the slit 9 of the cylindrical holding body 3, it is composed of a rootstock 5 and a scion 6. The graft support 1 can be easily and easily set in a direction in which the inclined surface of the cut provided on the seedling, that is, the joint surface 7 has an angle of 90 degrees with respect to the slit 9. That is, the installation position of the seedling can be instantly confirmed only by picking the picking section 11 by hand. Therefore, the cutting surface of the seedling can be surely inserted in the proper direction, and the work efficiency and the survival rate can be improved.

The picking portion 11 has two protruding portions 12, 1
Since it is formed from two, when the protrusions 12 and 12 are picked with fingers during the grafting work, the slit 9 and the seedling insertion hole 2 are formed.
Can be easily and sufficiently expanded, and even thick rootstocks 5 and spikes 6 can be easily inserted and can be securely held. Therefore, the seedlings can be easily inserted and the epidermis of the stems of the seedlings is less likely to be damaged. Further, after the grafting work is completed, a support 14 such as a toothpick may be inserted into the opening holes 13 provided inside the two protrusions 12, 12 to prevent the seedlings from falling when watering. it can.

Further, since the V-shaped groove 4 is formed so as to spread outward, the joint surface 7 of the seedling can be seen well, and the joint state can be easily observed. Further, a tangent line 10 between the V-shaped groove 4 and the seedling insertion hole 2, that is, a slit 9
Since they are in contact with each other without a gap, the spikes 6 can be held securely and effectively, the spikes 6 are less likely to fall, and the survival rate can be improved. Further, since there is no gap, it is possible to prevent the rootstock 5 and the scion 6 from drying. When the rootstock 5 or the scion 6 having a shaft diameter larger than the diameter of the seedling insertion hole 2 is inserted, the tangent line 10 is naturally the tangent line 10.
The gap between will expand.

Further, the seedling insertion hole 2 of the tubular holder 3 of the present invention is formed in an elliptical shape instead of a circular shape, and can be appropriately adapted to a seedling composed of a rootstock 5 and a spikelet 6 having different growth conditions. It is said that. That is, even if there is a thick or thick variation in the hypocotyls of the rootstock 5 and the scion 6, they can be firmly held without floating between them and a wide variety of seedlings can be obtained. It can correspond to the shaft diameter.

In particular, since the seedlings, that is, the joint surfaces 7 of the rootstock 5 and the scion 6 are cut obliquely, the elliptical shape is easier to insert than the circular shape, and there is an advantage that the epidermis of the stem is not easily damaged. Moreover, since the stalks of tomatoes, eggplants, and other saplings have a shape that is close to an ellipse rather than a circle, it becomes easier to insert them.

Further, as shown in FIG. 6, the seedling insertion hole 2 is formed at an eccentric position of the tubular holder 3, and the eccentric position is formed on the slit 9 side. That is, the width of A of FIG. 6 (width from the center of the tubular holding body 3 to the center of the seedling insertion hole 2) is eccentric to the slit 9 side. As a result, the wall thickness 8 of the wall portion 8 of the tubular holding body 3 on the back side of the slit 9 is formed to be thicker than the other portions.

Therefore, when the seedling grows after the grafting work is completed or when a seedling thicker than the inner diameter of the insertion hole 2 is pushed into the seedling insertion hole 2, the slit 9 of the V-shaped groove 4 becomes as shown in FIG. The wall portion 8 serving as a fulcrum of the tubular holding body 3 is opened to a load, but the wall portion 8 at this portion is formed thick so that the holding force is prevented from lowering and A sufficient holding force can be exhibited until the tree 5 and the scion 6 have become rooted, and the rooting rate can be improved.

Next, using the graft support 1 of the present invention,
The procedure for grafting fruits and vegetables such as tomatoes will be described below. In the grafting operation, first, the stem above the cotyledon of the rootstock 5 is cut obliquely by about 25 to 30 degrees. Next, while pinching the picking portion 11 of the tubular holding body 3 with a finger, the position of the V-shaped groove 4 provided on the opposite side is visually confirmed, and the hypocotyl of the rootstock 5 is placed in the seedling insertion hole 2. Insert about half. The picking operation of the picking portion 11 is not limited to picking, but simply holding the picking portion 11 of the tubular holding body 3 with a fingertip allows the slit 9 and the seedling insertion hole 2 to be naturally expanded. Work can be done efficiently and without damaging the seedlings.

In this insertion work, the seedling insertion holes 2 may be inserted into the rootstock 5 from above the rootstock 5, or the slits 9 and the seedling insertion holes 2 may be expanded and the rootstock 5 may be laterally mounted. The seedling insertion hole 2 may be inserted into the tree 5. On this occasion,
The inclined surface of the cut provided on the rootstock 5 is set in a direction having an angle of 90 degrees with respect to the V-shaped groove 4. Next, the scion 6 is cut at substantially the same angle as the rootstock 5, and the scion 6 is inserted into the seedling insertion hole 2 from above the tubular holder 3 to cut the rootstock 5 and the scion 6. The grafting work is completed by abutting the surfaces.

In this way, the rootstock 5 and the scion 6 are brought into a joined state by the tubular holding body 3, but the tubular holding body 3
Since the V-shaped groove 4 having the slit 9 is provided in the seedling insertion hole 2 of the above, the cylindrical holding body 3 and the hypocotyls of the rootstock 5 and the scion 6 do not come into close contact with each other. Appropriate air and water droplets will be able to flow, and the surface of the hypocotyl will not get damp and the seedlings will grow well.

Further, as the seedlings after grafting grow smoothly and the stems of the seedlings become thicker, the slits 9 formed on the tops of the V-shaped grooves 4 are gradually expanded and naturally separated from the seedlings. Therefore, the work of removing the graft support 1 can be avoided.

Furthermore, by inserting a support 14 such as a toothpick into the opening hole 13 of the graft support 1 after the grafting work is completed, it is possible to prevent a weak and weakly replanted sapling and promote growth. it can. That is, in many cases, the seedlings fall over due to watering, etc. By providing the opening holes 13 in the graft support 1, it is possible to prevent the seedlings fall over.

[0035]

As described above, in the graft supporting device of the present invention, since the gripping portion is formed on the tubular holder, the gripping portion is grasped by the finger of one hand during the grafting work. The V-shaped groove formation position can be automatically discriminated when it is inserted into the rootstock, and the installation direction of the inclined surface of the cut edge of the graft can be instantly known, enabling quick work.

That is, since the V-shaped groove is formed on the opposite side of the picking portion, the inclined surface of the cut provided on the seedling is easy in a direction having an angle of 90 degrees with respect to the V-shaped groove. And the graft support can be easily set. Therefore, the cutting surface of the seedling can be surely inserted into the proper position, and the work efficiency and the survival rate can be improved. At the same time, when inserting the rootstock and the scion into the seedling insertion hole of the tubular holder, the picking portion can be picked to open the seedling insertion hole, and the work can be performed without damaging the seedling.

Further, since the V-shaped groove is formed so as to spread outward, the joint portion of the seedling can be clearly seen through the slit, and the joint state can be easily observed. Further, since the tangent line between the V-shaped groove and the seedling insertion hole, that is, the slit is in contact with each other without a gap, the scion can be held securely and effectively, the scion is hard to fall, and the survival rate is high. It is possible to improve. Also, because there are no gaps, it is possible to prevent the seedlings from drying,

Further, the seedling insertion hole of the tubular holder is formed in an elliptical shape instead of a circular shape, and can be appropriately adapted to seedlings composed of rootstocks and spikes having different growth conditions.
In other words, even if there is a thick or thick variation in the hypocotyl of the rootstock and the scion of the scion, it can be firmly held without floating between them and is compatible with a wide range of stem diameters. can do.

Particularly, since the seedlings, that is, the joining surfaces of the rootstock and the scion are cut obliquely, the elliptical shape is easier to insert than the circular shape, and there is an advantage that the epidermis of the stem is less likely to be damaged. Moreover, the shape of the stalks of seedlings such as tomatoes and eggplants is not a circle but a shape close to an ellipse, so that it is easier to insert them, and work efficiency and survival rate can be improved.

Further, the seedling insertion hole is formed at an eccentric position of the cylindrical holder, and the eccentric position is formed on the slit side, and the wall of the cylindrical holder on the back side of the slit is formed. The wall is thick. Therefore, the grafted sapling grows, or when a sapling that is thicker than the inner diameter of the insertion hole is pushed into the sapling insertion hole, the slit expands, and the load is applied to the wall of the tubular hug that serves as a fulcrum. However, since this part is thickly formed, it is possible to prevent the reduction of the holding force and to exert sufficient holding force until the rootstock and the scion have lived, and it is possible to improve the survival rate. .

Furthermore, in the graft supporting device of the present invention, since the opening holes are formed inside the two ridges forming the knob of the tubular holding body, the opening holes are formed after the grafting work is completed. By inserting a support such as a toothpick into the sap, it is possible to prevent the seedlings from lodging when watered.
