Method for grafting subtropical plateau native Rhododendron with Rhododendron hybridum

Abstract

The invention discloses a method for grafting subtropical plateau native Rhododendron with Rhododendron hybridum comprising following steps: in mid-April, selecting 1-2 years old single-pole native Rhododendron from the mountain as a stock, and selecting Rhododendron hybridum branches having full branches and leaves, strong growth potential and no pest damage as scion woods; cutting the branches from the top of the stock and splitting the top of the stock in the middle; keeping two leaves in the Rhododendron hybridum scion woods; inserting the Rhododendron hybridum scion woods after peeling into the incision of the stock and binding the interface by plastic film; untying the tape after survival, and thinning leaves after 1-2 years and then shaping. Compared with present grafting method for Rhododendron hybridum, the provided method is simple and easy to operate, has high practicability and is easy to popularize; the method gives solutions to the problems that the appearance is affected due to unskilled grafting technology and the survival rate is low.

Description

Technical field [0001] The invention relates to a grafting method, in particular to a method for grafting Western rhododendrons on subtropical plateaus using local rhododendrons as rootstocks. Background technique [0002] Western Rhododendron is the most abundant flower type and flower color of Rhododendron. The main morphology is short and thick tree, dense crown leaves, long flowering period, and multiple petals. Highly ornamental [0003] The existing problems in the grafting methods of Western Rhododendron: Western Rhododendron is a valuable ornamental tree species, which is often used as a bonsai ornamental plant in horticultural research. It has high ornamental value and is rarely distributed in high-altitude areas in the west. The grafting and propagation technology requirements are strict. In addition, the existing grafting technology has high requirements for the timing of the seasons, and it is difficult to graft in the four seasons. It is limited to grafting only one t...

Problems solved by technology

[0003] Problems in existing grafting methods of Rhododendron: Rhododendron is a rare ornamental tree species, often used as a bonsai ornamental plant for horticultural research, its ornamental value is high, and it is rarely distributed in high-altitude areas in the west, and the requirements for grafting and propagation techniques are strict

Moreover, the existing grafting technology has high requirements on the timing of the seasons, and it is difficult to achieve grafting in four seasons. It is limited to only one type of species grafted on the same rootstock, which reduces the aesthetics of the finished product in the later stage, and the survival rate is not high.
