2. Description of the Related Art A grafting apparatus of this kind is composed of a scion transport conveyor for transporting a tray in which a plurality of seedling pots storing scion seedlings are arranged in a row, and a seedling pot storing stunting seedlings in a row. A rootstock transport conveyor for transporting a plurality of connected trays, and at a predetermined grafting position, cutting the ears from the scion seedlings conveyed by the above, and cutting the cut ears in the same manner. This is a device that automatically joins the pedestal from which the ears have been cut and removed from the rootstock.

[0003] In order to cut the spikes from the scion seedlings or rootstock seedlings, the upper and lower parts of the scionlings or rootstock seedlings are cut, and the seedling shaft at the lower part of the cotyledon is cut with a cutter or the like. However, if the position of the lower part of the cotyledon is automatically detected by a sensor or the like, particularly when the cotyledon of the seedlings is drooping downward, the dripping cotyledon becomes an obstacle to detection,
There is a risk that the cotyledons are mistaken for the seedling axis and cut.

[0004] For this reason, conventionally, for example, as for the scion side, as shown in Fig. 11, a raising seedling pot 19 conveyed by a scion conveying conveyor is opened and closed at a predetermined grafting position. The arm 17 is moved laterally to surround the scion seedlings 21, and then the raising arm 17 is moved upward to scrape the seedlings. In this state, the spikes and the lower part of the seedling shaft are held by the upper and lower clampers, respectively. And cut it with a cutter.
