[0026]
  Next, by holding the operation knob 19 of the cutting drive unit 16 and depressing the drive bar 18, the cutting blade is pushed and held in the support grooves 7 a, 7 b of the receiving unit 5 by holding the trunk of the contact wood A in the state described above. As shown in FIG. 10 (c) by 15, 15, the two opposite faces β, β of the trunk of the wood-contacting wood A are cut into a tapered shape, and then the above operation is repeated once again to face the opposite faces. By cutting γ and γ, as shown in FIG. 10 (d), a joining projection A 1 cut into a tapered hexagonal pyramid shape is formed at the lower end of the wood contact A.
[0027]
  Further, as shown in FIG. 11, the rootstock B formed by excising the upper part of the grafting seedling having affinity for the above-mentioned grafted wood A is held on the finger plate 41 of the rootstock holding member 40. Then, for example, while the drill blade 52 is rotated at a predetermined speed by the high-speed drill device 42, the drill device 42 and the drill blade 43 are lowered by an unillustrated lifting mechanism, and the processing portion 44 of the drill blade 43 is moved to the rootstock B. As shown in FIG. 12, a conical concave hole B <b> 1 with a narrowed bottom is formed in the upper end portion of the rootstock B.
[0028]
  In this way, after forming the projection A1 for joining at the lower end portion of the contacting wood A and forming the concave hole B1 at the upper end portion of the rootstock B, the contacting wood A and the rootstock B are aligned. By inserting the projection A1 for joining the wood contact A into the concave hole B1 of the rootstock B, as shown in FIG. 12, both are fitted to form a graft seedling.
[0029]
  As described above, the grafted wood A is formed by cutting the bottom part of the grafting seedling, and the installation interval of the blade surfaces 15a, 15a is gradually narrowed in a state where the trunk is held by the holding means 1. After cutting the two opposite surfaces of the trunk portion into a tapered shape by the cutting means 2 having a pair of cutting blades 15, 15, the cutting position of the trunk portion is changed by the rotational driving means 3 to make the tapered portion. By repeating the cutting operation only three times, the hexagonal pyramid-shaped joining projection A1 is formed on the trunk of the wood-timber A, so that the hexagonal pyramid shape is formed using a grafting device having a simple configuration. Can be formed appropriately and quickly.
[0030]
  That is, since the two opposing surfaces of the trunk portion are cut by the pair of cutting blades 15 and 15 in a state where the contacting wood A is held by the holding means 1, the opposing two surfaces of the trunk portion are formed. By cutting the two surfaces at the same time and cutting the stem to a constriction while preventing the destruction of the plant's ecological tissue by applying an equal cutting force to the two and balancing both cutting forces There is an advantage that the work to be performed can be performed quickly.
[0031]
  Then, as described above, a hexagonal pyramid-shaped joining projection A1 is formed by cutting the lower end portion of the contact wood A into a tapered shape, and the joining projection A1 is formed on the upper end portion of the rootstock B. A corresponding conical concave hole B1 is formed, and the joining protrusion A1 and the concave hole B1 are deformed by inserting the joining protrusion A1 into the concave hole B1. An excellent survival rate can be obtained by joining A and rootstock B in an appropriate state.
[0032]
  In addition, when the projection A1 for joining the wood contact A is inserted into the concave hole B1 of the rootstock B, the hexagonal pyramid surface and the conical surface constituting the joint projection A1 and the concave hole B1 are the guide surface. Since both are automatically aligned, the joining projection A1 can be easily inserted to the deepest part in the concave hole B1, and both can be joined in close contact. That is, by forming the joining projection A1 and the concave hole B1, the conduit a and the master tube b can be exposed on the entire peripheral surface, so that the joining projection A1 for the wood contact and the rootstock B When joining the concave hole B <b> 1, both the conduit a and the phlegm tube b can be easily and appropriately aligned.
[0033]
  Therefore, it is possible to adhere the joint portion between the wood graft A and the rootstock B without requiring a complicated operation such as holding the upper end portion of the rootstock B with a fixing aid such as a clip after the wood graft A is inserted. Can do. In addition, moisture and nutrients sucked up from the roots of the rootstock B after transplanting are smoothly supplied to the contacting wood A through the conduit a, and the contacting wood A grows and is photosynthesised. Since a photosynthesis product such as starch is supplied to the rootstock B through the teacher tube b, both the contacting wood A and the rootstock B grow in a well-balanced manner.
[0034]
  Furthermore, since the skin of the wood contact A is cut into a hexagonal pyramid over the entire circumference of the joint projection A1, the skin is prevented from being inserted into the concave hole B1 of the rootstock B. It is possible to reliably prevent rooting of the wood-timber A in the joint. In addition, since it is possible to improve the joining stability of the wood-contacting wood A and the rootstock B compared to the case where both the joining projection A1 and the concave hole B1 are cut into a conical shape, both are joined. Later, it is possible to effectively prevent the occurrence of a situation in which the joining portion rotates and the joining position shifts.
[0035]
