Embodiment 1
[0025] The replacement rootstock method that does not affect grape harvest of the present embodiment comprises the steps:
[0026] Such as figure 1 Shown, (1) plant two new rootstocks 5 (new rootstock 5BB grape seedlings) that need to be replaced symmetrically on both sides of the original grafted seedlings (scion sunshine rose, stock Beida grape). 5 plants carry out cross-cutting to form a cross-section, then obliquely cut downwards from the cross-section with a cutting knife, and cut a split 3, and form a 45° angle between the cutting knife and the cross-section (the angle range is 40° -60° can meet the requirements of grafting. When the included angle is less than 40°, the incision is too flat and should not be fixed with the wedge-shaped beveled surface 2 of the scion. When the included angle range is greater than 60°, the cleave angle is too large, which will cause the new wedge-shaped beveled surface 2 and the scion. Cleave 3 is owing to the hindrance of former stock 4 ...
Embodiment 2
[0031] The rootstock replacement method of this embodiment is the same as that of Embodiment 1, the difference is that the structure of the cutter used in this embodiment is as follows: Figure 3-Figure 4 As shown: the cutter includes a handle portion 6 and a cutting portion 7; the handle portion 6 is in the shape of a strip, one side of which is a concave arc 601 along the length direction; the cutting portion 7 is in the shape of a strip, one end of which is fixed by The shaft 702 is fixed on the surface of the concave arc 601 of the hand-held part; the other end is the end of the wedge-shaped knife edge 701, and the end of the knife edge 701 can move axially around the fixed shaft 702; The bit part 8 can limit the angle between the cutting part 7 and the handle part 6 between 0°-30°;
[0032] In order to limit the angle of the cutting portion 7 to 0-30°, the limiting portion 8 is a baffle with a fixed angle of 30° with the handle portion 6 .
[0033] In order to fit the ha...
