Embodiments of the present invention will be described below with reference to the drawings. First, the structure thereof will be described. The graft clip 3 is composed of a concave support body 1 and a plug support body 2 each formed of a resin material decomposable by light, microorganisms and the like. The concave support body 1 is formed in a bifurcated shape with its tip open, and the tip is wider than the base side to form a wedge shape on the inside, and the projections 4 are formed on the base side so that the left and right side surfaces are substantially parallel to each other. Is protruding backwards. The concave support 1 has a wedge-shaped inner surface with saw teeth 6 having a rear inclined surface 5 from the tip to the middle portion, and a U-shaped seedling receiving surface 7 from the middle portion to the base portion. Reference numeral 8 is a notch provided in the center of the seedling receiving surface 7 toward the rear.

The plug-like support 2 is provided with triangular projections 9 at both end portions of the tip plane, and a saw tooth 10 having substantially the same shape as the saw tooth 6 of the concave support 1 is formed on the outer surface of the base from the middle portion. Is provided. Reference numeral 11 denotes a circular hole penetrating in the vertical direction in the substantially central portion of both saw teeth 10, and 12 has a projection 13 having both left and right side surfaces substantially parallel to the base portion and protruding rearward. The plug-shaped support 2 is provided softer than the concave support 1.
It should be noted that the plug-like support 2 is provided with a soft saw tooth portion that is in close contact with the concave support 1.

The concave support supply device 14 is provided with a hand 16 at the tip of an actuator 15 which can reciprocate in the front-rear direction and which can be opened and closed in the left-right direction by using air (hydraulic pressure, motor, etc., but not limited to this) as a power source. It is provided. The plug-shaped support supply device 17 is the concave support supply device 14 described above.
The actuator 19 is provided with a hand 19 at the tip thereof.

FIG. 4 shows a case where the supports 1 and 2 are formed into a string shape and rolled. A plurality of concave support bodies 1 and plug-like support bodies 2 are wound around rollers 20 and 21 that are rotatably provided so as to be overlapped with each other, and the tips of each are located near the concave support body supply device 14 and the plug-like support body supply device 17. Is located in. Further, the feeding members 22 and 23 that are rotatably provided and sandwiched in the middle of each of them, and the support cutters 24 and 25 that reciprocate near the respective feeding devices 14 and 17 are provided. 26 is a scion seedling and 27 is a rootstock seedling.

Next, the operation will be described. First, when the feeding bodies 22 and 23 are rotated, the concave support 1
Then, the plug-shaped support body 2 is unrolled so that the respective tip ends reach near the concave support body supply device 14 or the hands 16 and 19 of the plug-shaped support body supply device 17. Then, the actuators 15 and 18 move forward to the support side, and the hands 16 provided at the respective tip end portions hold the concave support body 1, and the hand 19
Holds the plug-shaped support 2. Next, the cutter 24 reciprocates to cut the concave support 1 into a predetermined length, and the cutter 2
4 cuts the plug-shaped support 2 into a predetermined length.

The scion seedlings 26 and the rootstock seedlings 27 cut at a predetermined position are conveyed to the joining place by the conveying means and their cut surfaces are brought together. Then, the actuators 15 and 18
Moves forward to a predetermined position. Then, the plug-shaped support 2 fits into the recess-shaped support 1 and holds the joint surface between the scion seedling 26 and the rootstock seedling 27. After that, the hands 16 and 19 are opened, the actuators 15 and 18 retreat and return to their original positions, and the first grafting work is completed.

In this grafting work, the concave support 1 has a wide width with its tip open and has an opening angle from the base toward the tip side. Therefore, even if the stems of the grafting seedlings 26, 27 are bent, It can be easily pushed into the surface 7 side and is suitable for mechanization of grafting work, and can improve the joining performance. Further, since the outer surface of the plug-shaped support body 2 is provided in a taper shape having substantially the same shape as the inner surface of the concave support body 1, the plug-shaped support body 2 is smoothly fitted into the concave support body 1 and the seedlings 26, 2 are formed.
The holding power of the joint surface of No. 7 can be enhanced to prevent the seedlings from falling off.

The concave support 1 and the plug support 2 are also provided.
Have different hardnesses, that is, the portion of the sawteeth 10 of the plug-shaped support 2 is made softer than the portion of the sawteeth 6 of the concave support 1, so that the above-mentioned fitting becomes smoother. The plug-like support body 2 is held by the spring action of the hard concave support body 1. Then, since the soft flat portion sandwiched between the convex portions 9 and 9 and the seedling receiving surface 7 that is harder than that sandwich the joint surface, the joint surface and the shaft of each seedling 26 and 27 are strongly clamped and damaged. Can be prevented.

After the plug-like support body 2 is fitted, the sawteeth 10 provided on the outer surface are closely attached to the sawteeth 6 provided on the inner surface of the concave support body 1 to be locked, so that the front-back direction (actuator There is no omission in the direction of movement. Since the projections 9 are provided on both sides of the tip end plane of the plug-like support 2, the scion seedlings 26 are guided to the center side of the joint surface of the rootstock seedling 27 when they are held, and the stem bends and the joint surface shifts. Even if it occurs, it is possible to improve the bonding rate by correcting it. After grafting, the scion seedling 26
As the seeds grow, the convex portions 9 on both sides push open the concave support body 1, and by the pushing open action of the concave support body 1 due to the growth of the rootstock seedling 27, the concave support body 1 and the plug support body 2 are separated. Therefore, it is possible to save the trouble of removing both the supports 1 and 2.

Since the seedling receiving surface 7 of the concave support 1 is formed in an arc shape, the rootstock seedling 27 can be positioned at the center of the seedling receiving surface 7 when the seedling is held, and the scion seedling 26 The accuracy of aligning the joint surfaces with and improves, and the joint rate can be improved. Since the long notch 8 is provided at the center of the seedling receiving surface 7 toward the projection 4, the natural detachment of both the supports 1 and 2 due to the growth of the grafted seedling can be enhanced.

Since the projections 16 and 18 are provided on the back surfaces of the concave support body 1 and the plug-like support body 2, the respective support bodies 1 and 2 are provided.
Positioning is easy and suitable for mechanization. Further, since the hole 11 is vertically penetrated through the central portion of the plug-shaped support body, the scion seedling 26 and the rootstock seedling 27 are inserted when the plug-shaped support body is fitted into the concave support body 1.
A cushioning action works when pressing the so as to smooth the fitting and prevent the crushing of the stem.

Then, the concave support 1 and the plug support 2 are provided.
Since it is made of plastic that is degradable by light, microorganisms, etc., it is possible to save the trouble of recovering by spontaneously dropping and then decomposing. Further, since the two supports 1 and 2 are formed in a string shape, they can be handled easily and the supports do not get entangled with each other, so that it is possible to prevent a joining error due to a defective supply of the supports.
