Problems solved by technology

[0002] Grape is a subtropical fruit produced in Guangxi. Grafting is a common cultivation method. However, when cultivating grafted seedlings, the planters found that the grapes began to bear fruit after 1-2 years after the grafted seedlings were planted. Only then did they discover The rootstocks of grape seedlings are not suitable for local planting, the yield is very low, and they are greatly affected by diseases and insect pests. At this time, the rootstocks need to be replaced. The conventional operation is to re-select suitable rootstocks, reprocess the scions, and then perform grafting again. However, this The operation often has to wait for 1-2 years before harvesting; such replacement of rootstock will seriously affect the grape harvest and cause very large economic losses to farmers. For this reason, it is necessary to find a replacement that does not affect the grape harvest for the above-mentioned problems The rootstock method, which can improve the survival rate of grafted seedlings, does not affect the grape harvest, and can also achieve the purpose of replacing the rootstock

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...

Abstract

The invention relates to the field of agricultural planting, especially to a rootstock replacing method without affecting grape harvesting. According to the method, rootstock replacement is carried out on grape grafted seedlings which grow for 1-2 years and start to bear fruits, it is guaranteed that grapes are borne on the seedlings in the same year, and the survival rate of the grafted seedlingsis ensured; when rootstock replacement and grafting is conducted, traditional grafting modes of a scion of a single rootstock is not adopted, a new rootstock is planted beside a grafted plant, and ascion is directly grafted without cutting off an original rootstock and an original scion, thereby forming a transition growth system with one scion and two rootstocks (the original rootstock and thenew rootstock); after the thickness of the new rootstock is similar to the thickness of the original rootstock, the nutrient supply of the living scion can be guaranteed, and then the original rootstock is cut off; and thus, with such a grafting mode, the survival rate of the grafted seedlings after rootstock replacement is guaranteed, harvesting of grapes is not affected, dominant rootstocks canbe replaced, and losses of peasant households are reduced to the maximum extent.
