Grafting method adopting inverse cutting and sequential grafting

A technology of incision and interface, which is applied in the field of grafting with oblique incision and reverse cutting, which can solve the problems of easy loosening, small contact area between scion and rootstock incision, and low survival rate, so as to achieve the goal of not being easily broken by wind, improving the survival rate of grafting and plant growth The effect of volume, interface healing and firmness

Problems solved by technology

[0002] Existing branching methods such as laparotomy grafting are tangential and tangential grafting, that is, the lower end of the scion is cut into a wedge shape and inserted into the rootstock incision to fix it. The contact area between the scion and the rootstock incision in this grafting method is small, and there are still 2 holes after grafting. / 3~3 / 4 long scion protrudes on one side of the rootstock, which is easy to loosen and the survival rate is low; this deficiency also exists in other branch grafting methods

Embodiment 1

[0020] Embodiment 1: Kudingcha 1-year biotechnological strip connection:

[0021] ①Cut and cut the scion: in June, select a branch that grows normally and robustly, with a diameter of about 0.5 to 0.8 cm, and cut it to a length of 5 to 7 cm to make a scion (the lower end is a horizontal incision), and leave a bud and a leaf in the middle and upper parts , cut off the leaves and only leave the petiole; when cutting, cut a 0.5-0.8 cm long oblique surface above the petiole on the back of the scion and about 0.5-1 cm away from the bud (make the slope and the length direction of the scion at 30°~ 40° intersection angle), and then cut a longitudinal incision on the ventral surface of the scion from bottom to top, reaching as deep as the xylem;

[0022] ②Choose and cut rootstocks: directly select 2-3 years old artificially seeded seedlings in the nursery as rootstocks. An oblique incision of 5.5 cm to 7.5 cm in length is cut below the rootstock at an angle of 30° to 40° to the heigh...

Embodiment 2

[0026] Embodiment two: the upside-down connection of two section branches of sassafras tree:

[0027] ① Selecting and cutting the scion: at the end of December, select the second branch of the sassafras tree that grows robustly, with a diameter of about 0.7 to 1 cm, and cut it to a length of 6 to 7 cm to make the scion; ~0.8 cm long oblique surface (30°~40° intersection angle with the length direction of the scion), and then cut a longitudinal incision on the ventral surface of the scion from bottom to top, reaching the xylem;

[0028] ② Select and cut rootstock: select 1-year-old artificially sown Sassafras saplings as the rootstock, after raising the seedlings (grafting from the anvil), cut it from 10 centimeters above the rhizome, and first obliquely cut a 0.5 centimeter long 3 to 4 centimeters below the cutting edge of the rootstock. ~0.8 cm long oblique incision, at an angle of 30°~40° with the height direction of the rootstock, and then cut a longitudinal incision with a...

Abstract

The invention relates to a grafting method for grafting a scion to an oblique incision inversely cut in a root stock. A conventional scion grafting method adopts obverse cutting and sequential grafting, after grafting, the contact area of the scion and the incision of the root stock is small, the scion is easy to loose, and the survival rate of plants is low. The grafting method disclosed by the invention comprises the following steps of peeling the upper end of the back of the scion into a bevel of 30-40 degrees (namely inverted cutting), and peeling a longitudinal incision which is as deep as a xylem in the ventral surface of the scion; inversely cutting an oblique incision of 30-40 degrees in the upper end of the grafting part of the root stock, and downwards cutting a longitudinal incision which is as deep as the xylem from the oblique incision; during grafting, inserting the scion into the oblique incision of the root stock in a manner that the bevel of the upper end of the scion is outwards, and enabling the longitudinal incision of the scion and the longitudinal incision of the root stock to be closely connected and fixed; and performing management. According to the grafting method, two seam healing surfaces are generated, after grafting, the scion is completely jointed to the root stock, the scion and the root stock are easy to fix, the contact area of the incision is large, and increasing the grafting survival rate and increasing the growth amount of plants are facilitated.

Description

technical field [0001] The present invention relates to a kind of grafting and breeding method, especially a kind of grafting method of scion and rootstock with oblique incision and back cutting. Background technique [0002] Existing branching methods such as laparotomy grafting are tangential and tangential grafting, that is, the lower end of the scion is cut into a wedge shape and inserted into the rootstock incision to fix it. The contact area between the scion and the rootstock incision in this grafting method is small, and there are still 2 holes after grafting. The 3-3 / 4 long scion protrudes on one side of the rootstock, which is easy to loosen and has a low survival rate; this deficiency also exists in other branch grafting methods. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention is to provide a grafting method with reverse cutting and straight grafting, so as to improve the success rate...
