Plant grafting method

Abstract

The invention relates to a plant grafting method which comprises the following steps that (1) a branch stock to be grafted is selected, and cut open from one fourth of the diameter, then the tree bark and the pith at the one-fourth part are separated, and then the pith is cut off; (2) the outer bark on both side surfaces of a branch to be grafted is removed, wherein the whole outer bark of one side surface is removed and only the bark on the outermost layer of the other side surface is removed; and (3) cuttage is carried out: the branch to be grafted in step (2) is grafted to the ear of grain and inserted into the incision of the stock, one side, on which the bark is fully removed, of the grafted branch is in alignment with one side of the pith of the stock, one side, on which only the bark on the outermost layer is removed, of the grafted branch is coincident with one side of the outer bark of the stock, then bandage is carried out to complete the grafting. The graft union has good healing performance and high growth speed.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a plant grafting method (h-type grafting method). Background technique [0002] Plant grafting is carried out by utilizing the ability of plants to heal after injury. During grafting, the cambiums of the two injured surfaces are brought close together and tightly bound together. As a result, due to cell proliferation, they heal each other and become a whole connected by vascular tissues. [0003] Grafting is of great significance to the propagation of some fruit trees that do not produce seeds (such as persimmon, some varieties of citrus). Grafting can not only maintain the excellent traits of scion varieties, but also utilize the favorable characteristics of rootstocks to achieve early fruiting, enhance cold resistance, drought resistance, and resistance to diseases and insect pests, and can also economically utilize propagation materials and increase the number of se...

Problems solved by technology

[0006] At present, there are three kinds of grafting methods that are most used: leaning method, splitting method, and plugging method. However, the low survival rate of these three methods leads to the high price of finished seedlings after grafting, and the reasons for the low survival rate of grafting are as follows: 1. The cambium layers of rootstock and scion are not closely overlapped

2. The size of rootstock and scion is limited (the thickness of rootstock and scion must be close to make the cambium closely overlap)

3. No phytohormones are used to promote wound healing

The following is one of the traditional grafting methods; the traditional grafting method is that the conjunctive bark (cambium) joint surface is small, and the grafting survival rate of the tree species with thinner bark is low

[0007] The above reasons caused the grafting to be inactive, which reduced the survival rate of the grafted scion and also destroyed the rootstock.
