2. Description of the Related Art Eggplants and other vegetables have been difficult to cultivate due to diseases of soil bacteria and physiological disorders caused by continuous cropping. As countermeasures, the development and development of rootstocks with strong disease resistance have been advanced, and the technology of grafting them to excellent varieties (spikes) has been developed, and many inventions have been proposed. In recent years, many robots have been proposed. The origin of grafted seedlings is the Japanese Patent Publication No. 53-467 developed by the present inventor
In recent years, there has been a tendency to simplify the system and put it to practical use.
No. 30 has a diameter enough to elastically hold the outer circumference of the grafted joint over substantially the entire circumference, and has a graft support made of a synthetic resin elastic cylindrical body provided with a cut extending from one end to the other end. A graft support, wherein at least an upper end face of upper and lower end faces of the elastic body is an inclined cut surface corresponding to an inclined surface of a cut in the graft with respect to the axis of the cylindrical body. Tool. According to the gazette, the present invention improves the disadvantages of the conventional method of clamping and fixing the grafted portion with a clip in the form of a washing pin, the grafting operation is simple, and the growth of the grafted portion is achieved by cutting in the vertical direction. However, it is said that the support falls off naturally, but as the shape of the support is cylindrical, it can be considered to be firmly clamped as the graft grows. The effect is not expected.

JP-A-3-58718, "Gripping Method and Grafting Tool" A graft and a scion are cut, and a grafted portion in which the grafting surface of the scion is combined with the grafting surface of the scion is made of a heat-shrinkable plastic. After attaching a certain grafting device, by applying heat to the grafting material and shrinking it, the grafting surface between the stock and the scion is brought into close contact, and a grafting method for retaining the scion to the stock is a device for the grafting. Is
It may be in the form of a tube or tape, or a cut may be formed at the end of the tube. In this case, there are many questions as to whether the material and the shape can be adapted and the rootstock and the scion of the graft, which are young plants, can be safely bonded and produced.

Japanese Patent Application Laid-Open No. 3-244322, "Gripping Method and Apparatus" Japanese Patent Application Laid-Open No. 4-48717, "Calling Method" Japanese Patent Application Laid-Open No. 4-99415, "Calling Method Using a Seedling Holding Device" It is thought that this invention will be a stepping stone for future automation (robotization) using a rather complicated mechanism by using the invention of the direction of robotization using the "joining method", but the target is young plant seedlings Yes, there is a feeling that these complicated mechanisms can be endured or put to practical use.

[0005] Japanese Patent Application Laid-Open No. 1-273517, "Glue and grafting method for grafting" This proposal is applied to any of cutting, splitting, and cross-joining, and is used for grafting containing 2-cyanoacrylate as a main component. It is an adhesive.
-A grafting method characterized in that an adhesive mainly composed of cyanoacrylate is applied to the periphery of the cut surface outside the contact portion, and the scion and the rootstock are fixed. In addition, in this adhesive,
Many kinds of preservatives, such as instant adhesives, are used, and their relationship with seedlings (rootstocks, scions) cannot be questioned unless they are the results of considerable experiments.

Japanese Unexamined Patent Publication No. Hei 2-107125, "A grafting seedling manufacturing apparatus" Japanese Unexamined Patent Publication No. 3-61429, "A grafting apparatus" Japanese Unexamined Patent Publication No. 1-252228, "Automatic grafting apparatus" Japanese Unexamined Patent Publication No. 2-190118, "A young grafting apparatus" Is intended to automate (robotization) the grafting technology that required skill by hand, but its mechanism is extremely complicated, and its value must be extremely expensive. It is worthwhile to raise many questions as to whether the grafting of stakes started from the preparation of rootstocks and scions, and that they could be put to practical use by cutting, bonding and preserving them and contributing to the grafting industry. There is, however, the question of whether the nursery industry can adopt it today.

[0007]

In order to solve the above-mentioned drawbacks of the prior art, as a result of an experimental study, the present inventor first attempted to simplify the grafting method as much as possible. In the relationship between instruments that conform to the above and research on the properties of the properties of the instruments, especially in relation to the seedlings that are the subject of the present invention, the instruments are more suitable than the seedlings, depending on the form of use and the growth of the seedlings after grafting. Emphasis was placed on preventing the growth of seedlings from falling off naturally, and efforts were made to complete the present invention.

[0008]

According to the present invention, as set forth in the appended claims, the grafting method of the present invention has a close and inseparable relationship with the instrument used in the present invention, and the two are described separately.
