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 based on Japanese Patent Publication No. 58-3693 developed and invented by the present inventor.
No. 4, etc., which tend to be simplified and put into practical use in recent years.
No. 0 has a diameter enough to elastically hold the outer periphery of the grafted joint over substantially the entire periphery, 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.

点が多い。JP-A-3-58718, “Grafting method and grafting device” A graft and a scion are cut, and a grafted portion in which the grafting surface of the stock is combined with the grafting surface of the scion is made of a heat-shrinkable plastic. After attaching a certain grafting material, 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 the grafting method is to retain the grafting to the stocking. ,
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 doubts as to whether the material and the shape can be adapted to each other and the graft and the spikes, which are young plants, can be safely bonded and produced.

The lower end of the grafting board, and the lower end of the cutting board between the slightly softer synthetic resin of the scion side and a special structure. It is positioned slightly above the grafting board and slightly above the cutting upper end S 'of the rootstock, so that the cutting lower end of the scion covers the cutting lower end S "of the rootstock. The grafted part is almost completely enclosed inside the grafting board, and the cutting upper end of the scion is located at the upper end of the stock, so that the grafted part of the grafting board is sufficiently protected and after the grafting. Of the hardness between the grafting board on the rootstock side and the grafting board on the scion side according to the development of the joints The grafting plate falls off naturally, and has a great effect of not giving any support to its growth. It is also effective in joining with the scion.In the arc-shaped groove at the center of the grafting board, both the stock and the scion are bonded by the ridges 3, 7 in the arc-shaped joining groove. The projections prevent the air and water from entering the grafting board and enhance the bonding effect.The joining projections 4 and the holes 8 of the grafting board of the present invention can be provided on either the stock side or the scion side. However, it is preferable that the joining protrusions 4 are provided on a slightly harder synthetic resin side of the rootstock for convenience of use, and one example of a rootstock plant used in the present invention is as follows. To name a few, Kiuri, Unryu No.2 for Chiuri, Melon and Shirouri,
