DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to grafted seedlings and grafts.
About the method .

[0002]

2. Description of the Related Art Hypocotyls are cut from the short circle direction.

[0003]

[Problems to be Solved by the Invention] The grafting seedling and grafting method of the above-mentioned means cuts from the short circular direction, so
The length becomes shorter and the joint becomes unstable.

[0004]

Means for Solving the problems] The present invention provides the following technical means. That is, the invention according to claim 1 is:
The scion 1 or the stock 2 is attached to the hypocotyl 5 from the oblong direction of the hypocotyl 5 .
And cut diagonally to obtain grafted seedlings obtained by joining the cut surfaces. The invention according to claim 2 is a joint
Wood method.

[0005]

[Effect] The embryo 1 or the stock 2 is placed in the direction of the ellipse of the hypocotyl 5 from the embryo.
Cut diagonally to axis 5 . Then, the respective cut surfaces are joined by joining means.

[0006]

[Effect] The embryo 1 or the stock 2 is placed in the direction of the ellipse of the hypocotyl 5
Since the cutting is performed obliquely with respect to the axis 5, the cutting length must be large.
And the bonding becomes stable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below. First, the structure will be described. Reference numeral 3 denotes a scion hypocotyl hand for gripping a hypocotyl 5 of a scion 1 having cotyledons 4. Reference numeral 6 denotes a movement locus of a cutter (not shown), which cuts the hypocotyl 5 of the scion 1 on the way. 2 is a stock having cotyledons 7 and hypocotyls 8, and 9 is a clip.

Next, the operation will be described. First, the scion 1 set at a predetermined position is gripped by the scion hypocotyl hand 3 and carried to the cutting position. Next, a cutter (not shown)
Cuts the middle part of the hypocotyl 5 through the movement locus 6 from the direction of the ellipse. In addition, as shown in FIG.
Is cut diagonally. Then, the scion 1 is carried to the joining position by the scion hypocotyl hand 3. On the other hand, the stock 2 is also cut at a predetermined position and then carried to the joining position, and then joined to the cut surface of the scion 1 with the clip 9. The stock 2 is cut not in the oblong direction but in the short circle direction as in the scion 1. Accordingly, as for the joining posture of the scion 1 and the stock 2, the cotyledons 4 and 7 are located at substantially right angles as shown in FIG. 4.
In this example, the case where the hypocotyl 5 of the scion 1 was cut and joined from the oblong direction was described, but the stock 2 was cut from the oblong direction and the scion 1 was cut from the short direction. You may join.

Therefore, the cotyledons 5 of the scion 1 and the cotyledons 7 of the stock 2
And light do not hit each cotyledon 5 and 7, and uneven growth does not occur. Further, since the cutting length can be increased by cutting in the elliptical direction, the joining is also stabilized. In FIG. 5, at the time of joining (grafting), the true leaves of the scion 1 are differentiated, and the length of the hypocotyl 5 after cutting is within 15 mm. If the length of the cuttings 1 after cutting is long, the upper part weight increases as the true leaves become larger during acclimation and seedling raising. For this reason, the joint surface may easily fall due to external force (for example, wind) and may be separated.
Therefore, this problem can be solved by setting the length of the hypocotyl 5 within 15 mm as described above. If the graft is grafted before the true leaves of the scion 1, the hypocotyl 5 will elongate until the true leaves come out. Conditions.
