PROBLEM TO BE SOLVED: To provide a grafting tool whose price is set as low as possible to be disposable, and which falls off corresponding to growth of a scion, and which eliminates the need of removal work.SOLUTION: A grafting tool has: a tubular grafting tool body 1 having uniform thickness and a slit 12 installed on a side wall part 10 of the grafting tool body 1 so as to connect both ends 11 in extending directions of the grafting tool body 1, in which the grafting tool body 1 includes elasticity and a gap of the slit 12 widens/narrows, and when a portion where a scion is connected to a rootstock is inserted into a penetration hole penetrating both ends 11 in extending directions to fix the scion, the slit 12 widens as the scion grows to a predetermined size, and falls off from the portion where the scion is connected.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】使い捨てとすることが可能な程度に価格を抑え、また、穂木の生育に応じて離脱して取外し作業を不要とする接ぎ木具を提供する。【解決手段】均一な厚さの管状の接ぎ木具本体1と、前記接ぎ木具本体1の側壁部10に、該接ぎ木具本体1の延設方向両端間11を結ぶように設置されたスリット12とを有し、前記接ぎ木具本体1は、弾性を備えて前記スリット12の間隙が拡縮し、前記延設方向両端部11間を貫通する貫通孔に、台木に穂木を接いだ部位を挿通して前記穂木を固定したとき、前記穂木が所定の大きさに生育すると前記スリット12が拡開して前記穂木を接いだ部位から離脱することを特徴とする。【選択図】図1
