A kind of grafting cultivation method of Euonymus plant golden beetle

Abstract

The invention relates to the technical field of plant cultivation, in particular to a grafting cultivation method for euonymus golden armors. The grafting cultivation method comprises the steps that flooding is performed on stock plots after sunset one day before grafting; annual robust branches of golden armors are selected as a scion material for manufacturing scions, and a scion grafting or bud grafting method is adopted for grafting the scions to stock. According to the grafting method, grafting time, scion and bud grafting positions, screening and modification are performed during post-grafting management, the armors with the good characters are grafted to congeneric Hokkaido Chinese littleleaf boxes, and the good characters of two parents can be kept in a vegetative propagation mode. Compared with a traditional propagation method, on the basis of the method, the golden armor and Hokkaido Chinese littleleaf box grafting propagation technology is performed, later generations show the good ornamental characters of the golden armors, the drought resistance and cold resistance can be improved, and the survival rate can be increased to 90% or above from smaller than 70%.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for grafting and cultivating a plant of the genus Euonymus chrysalis. Background technique [0002] Euonymus japonicus Thunb., also known as Euonymus japonicus Thunb., is a shrub or small tree of Euonymus japonicus Thunb. Branchlets four-sided, with fine wrinkles. The leaves are leathery, shiny, obovate or oval, native to Japan, and introduced to my country from Hokkaido, Japan in 1986, also known as "Japanese holly" and "Japanese boxwood". It is a kind of evergreen broad-leaved tree species with strong cold resistance, wide range of suitable growth and fast growth. It is evergreen in four seasons, leaves are not deciduous, and the leaves are leathery. The leaves are larger, round, thicker and slightly edged than ordinary Euonymus euonymus Reverse upward, obvious leaf veins, green and shiny leaf color, unchanged in winter; it has certain ornamental and greeni...

AI Technical Summary

Problems solved by technology

[0004] Hokkaido boxwood and the new variety "Golden Armor" belong to the genus Euonymus of the family Euonymus. Currently, the commonly used propagation methods of Euonymus plants include seed propagation and cutting propagation. The traditional propagation methods have disadvantages such as long growth cycle, slow growth, and high breeding costs. , which seriously restricts large-scale seedling cultivation

Moreover, the single trait also reduces its ornamental value.

However, there is no grafting technology of Hokkaido boxwood and the new variety "Golden Armor"
