Graft method in inverted cutting and joint in positive direction

A technology of incision and scion, which is applied in the field of grafting with oblique incision and reverse cutting, which can solve the problems of easy loosening, low survival rate, and small contact area between scion and rootstock incision, so that it is not easy to break in the wind, the interface is healed firmly, and the survival of grafting is improved. The effect of rate and plant growth

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 has a low survival rate; this deficiency also exists in other branch grafting methods

Embodiment 1

[0023] Embodiment one: 1 year old branch of Kudingcha is grafted upside down (referring to figure 1 , 2 ):

[0024] ① Selecting and cutting 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 transverse incision 3), and leave a bud and a branch in the upper and middle parts. Leaves, cut off the leaves and only leave the petiole 2; when cutting, cut a 0.5-0.8 cm long incline 1 at the top of the petiole on the back of the scion and about 0.5-1 cm away from the bud (make the slope 1 in the direction of the length of the scion) 30°~40° intersection angle), and then cut a longitudinal incision 4 on the ventral surface of the scion from bottom to top, reaching as deep as the xylem;

[0025] ②Choose and cut rootstocks: directly select 2-3 years old artificially seeded seedlings in the nursery as rootstocks. An oblique incision 5 of 1 cm is formed at an ...

Embodiment 2

[0029] Embodiment two: the upside-down connection of two section branches of sassafras tree:

[0030] ① Selecting and cutting the scion: at the end of December, select the second branch of the sassafras tree 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;

[0031] ②Choose and cut the rootstock: select 1-year-old artificially sown Sassafras saplings as the rootstock, cut off from the 10 cm above the rhizome after raising the seedlings (grafting from the anvil), and first obliquely cut a 0.5~ A 0.8 cm long oblique incision is made at an angle of 30° to 40° to the height direction of the rootstock, and then a longitudinal incision with a length of 6 to 8 cm is cut below the incision, reaching as deep as the xylem;

[0032] 3. g...

Abstract

A reverse-cutting and opposite-inserting graft method features that the back of scion is cut to become a (30-40)-degree oblique surface, its front surface is cut to form a longitudinal nick reaching xlem, a (30-40)-degree oblique nick and a longitudinal nick reaching xylem are cut on the stock, and the scion is inserted in the stock and fixed to it. Its advantages are high survival rate and high growing speed.

Description

【Technical field】 [0001] The invention relates to a grafting and breeding method, in particular to a grafting method of scion and rootstock with oblique incision and reverse 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 long scion of / 3~3 / 4 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. 【Content of 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 of grafti...
