Abstract

PURPOSE:To produce high-quality graftings by winding an adhesive tape on the outer periphery of a bonding part of cut faces of scion and stock or sandwiching the bonding part in between the adhesive tape from both the sides and bonding so that inner faces of the adhesive tape are rubbed to bond the bonding part of the cut faces of scion and stock. CONSTITUTION:A stock 1 to be subjected to grafting and a hypocotyl of a scion 2 are cut slantingly, respectively, at a grafting position and cut faces are brought into contact each other to give a bonding part 3 of cut faces. Then an adhesive tape 4 is wound on the bonding part of cut faces in such a way that bonding faces 5 of inner faces at both ends are opposed, the opposing parts of the adhesive tape 4 are rubbed from the outside to the bonding part 3 of cut faces and the whole bonding part 3 is bonded. The opposing part of the adhesive tape 4 is cut at a cutting part 6 so as to leave a fixed amount of the opposing part. Consequently, the bonding part 3 of cut faces is bonded by the adhesive tape 4 and grafting operation is completed. Therefore high- quality graftings are produced.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a grafted tree in which a scion and a rootstock are cut at predetermined positions, and each cut surface is glued to produce a grafted seedling. This invention relates to a method for adhering grafted seedlings.

[Conventional technology]

Conventionally, a grafting method has been known in which a scion and a rootstock are cut at predetermined positions, and the cut surfaces of each are adhered to produce a grafted seedling. Clips, adhesives, rubber tubes, and the like have been put into practical use as bonding materials for the grafted joint.

[Problem to be solved by the invention]

By the way, the above-mentioned clip as a joining material has problems in that it is expensive and it is troublesome to remove it. Adhesives (~) had the problems of poor handling and low adhesion rates.

Rubber tubes have various problems, including poor workability and poor adaptability to various seedlings.

The present invention has been made to solve the above problems.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a grafting method in which a scion and a rootstock are cut at predetermined positions, and each cut surface is glued to produce a grafted seedling. Wrap a tape with an appropriate width around the outer circumference of the joint so that the inner surfaces of both ends are facing each other and adhere to the joint, or sandwich the tape from both sides and adhere the inner surfaces of the tape to each other, then wrap the tape around the joint. It is characterized in that it is made to be joined by adhering up to the point.

[For production]

By the above means, the present invention wraps the outer periphery of the joint where the cut surfaces of the scion and the rootstock are joined together using an adhesive tape (or pinches the tape from both sides to squeeze the inner surfaces of the tape together). By gluing, the cut surfaces of the scion and rootstock are bonded together.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In Figs. 1 to 3, reference numeral 1 indicates a rootstock for grafting, 2 indicates a scion, and 3 indicates the hypocotyls of the rootstock 1 and the scion 2, which are cut diagonally at the position to be grafted. This is a cut surface joint where the respective cut surfaces are brought into contact with each other. As shown in FIGS. 2 and 3, this cut surface joint 3 is made by wrapping its outer periphery with an adhesive tape 4 having an appropriate width so that the adhesive surfaces 5 on the inner surfaces of both ends are in contact with each other. Squeeze the facing part of the adhesive tape 4 toward the cut surface joint 3 to adhere it to the very edge of the joint 3, and cut it at the cutting part 6 while leaving the facing part almost constant. is supposed to be glued.

In the grafted seedling adhering means having such a configuration, as shown in Fig. 1, the hypocotyls of the rootstock 1 and the scion 2 to be grafted are cut diagonally at the position to be grafted, and the cut surfaces of each are cut. The cut surfaces are brought into contact with each other to form a joint portion 3 (FIG. 2A). Then, as shown in FIG. 2, 81, and 3A, the adhesive tape 4 is wrapped around the cut surface joint 3 so that the adhesive surfaces 5 on the inner surfaces of both ends are in contact with each other, and the opposing portions of the adhesive tape 4 are wrapped from the outside. The adhesive tape 4 is glued to the edge of the joint part 3 by squeezing it toward the joint part 3 of the cutting surface, and is cut at the cutting part 6 so that a substantially constant amount of the contacting part of the adhesive tape 4 remains. In this way, the cut surface joint portion 3 is adhered with the adhesive tape 4, and the grafting work is completed.

The root part of the grafted seedling is planted in a seedling box or the like on the rootstock side, acclimatized, and grown by taking root.

During acclimatization until the seedlings take root, as shown in Figure 6A,
The cut surface joint part 3 is fixed by the adhesive tape 4, but after rooting, the hypocotyl grows and becomes thicker as shown in 2a (then, as shown in Figure 6B and B', the adhesive tape 4 When the contact portion is pulled and gradually peeled off, and the hypocotyl grows further and becomes thicker, the contact portion of the adhesive tape 40 separates and comes off from the seedling, as shown in FIG. 6C.

The work of wrapping and bonding the cut surface joint 3 with the adhesive tape 4 can be done not only manually but also easily by mechanization or automation. Further, the adhesive tape 4 is desirably made of a material that is water permeable, elastic, and has appropriate degradability.
It is desirable that the adhesive strength decreases over time.

In another embodiment of the present invention shown in FIGS. 4 and 5, an adhesive tape 4 is arranged to sandwich the cut surface joint 3 from both sides, and the adhesive surfaces 5 on the inner surface of the tape 4 are bonded together. Then, run the tape 4 from both sides of the joint 3 to the very edge of the joint 3 (to adhere the cut surface joint 3,
The tape 4 is cut at the cutting section 6 so that a substantially constant amount of the opposing portion remains.

In this embodiment as well, FIGS. 4A-D and 5
As shown in Figures A and B, the rootstock 1 and scion 2 are
The cut surface joint 3 is sandwiched and adhered with adhesive tape 4 from both sides. In this embodiment as well, it is easy to mechanize and automate the work of gluing the cut surface joints 3 with the adhesive tape 4, and the adhesive tape 4 used is the same as that in the above embodiment. is desirable.

The adhesive tape 4 used in the grafted seedling adhering means of the present invention is cheaper than conventional clips and rubber tubes, and does not need to be removed later like clips (and does not need to be removed later like adhesives). There is no problem of poor handling or low survival rate, and all of the problems of rubber tubes, such as poor workability and poor adaptability to various seedlings, have been solved.

〔Effect of the invention〕

As explained above, according to the method for adhering grafted seedlings in grafting of the present invention, the following effects can be achieved.

■ Wrap the outer periphery of the joint between the cutting surfaces of the scion and rootstock with a tape of appropriate width so that the inner surfaces of both ends are facing each other and adhere to the joint, so that the cutting surface of the scion and rootstock can be easily The joint can be simply and easily glued and fixed, and a high-quality graft can be produced.

■ Also, the outer periphery of the joint between the cutting surfaces of the scion and 6th tree is sandwiched from both sides with tape of an appropriate width, the inner surfaces of the tape are glued together, and the tape is glued up to the joint to join. The cut surface junction of the scion and the rootstock can be simply and easily glued and fixed, and a high-quality graft can be produced.

■Furthermore, the tape itself is inexpensive, and it can reliably bond the cut surface of the scion and rootstock to produce grafted seedlings with a high survival rate. There is no need to remove the tape, making it highly adaptable to a variety of seedlings (
, versatile.
