Problems solved by technology

[0004] The eucalyptus is bred from the native tree species of eucalyptus chinensis. Compared with eucalyptus chinensis, it has obvious difference in leaf color, and the leaf color is golden yellow, which is very beautiful. But what method should be adopted in the breeding process to ensure the stability of eucalyptus chinensis obtained? performance and goodness are still an unresolved issue

Abstract

The invention relates to a koelreuteria paniculata grafting method. The method comprises the following steps that two-year North China koelreuteria paniculata seedlings are used as rootstocks, annualkoelreuteria paniculata hard branches are used as scions, and a bark grafting mode is selected for grafting. The method has the beneficial effects that a hard branch cleft grafting method is adopted in the koelreuteria paniculata grafting method, scions are treated with a No. GGR8 green plant growth regulator, and the survival rate of obtained grafted seedlings reaches 81.7%. The disease resistance and cold resistance of the koelreuteria paniculata seedlings obtained through the koelreuteria paniculata grafting method are high and are hardly different from those of koelreuteria paniculata, thekoelreuteria paniculata seedlings have better ornamental value, and the ornamental period can reach 200 days or longer.

Description

technical field [0001] The invention belongs to the field of plant grafting, and in particular relates to a method for grafting eucalyptus japonica. Background technique [0002] In the north of our country, there is a shortage of brightly colored tree species with colorful leaves. Purple-leaved plums are dark in color. After falling leaves, the yellow branches are exposed. In the past, our country imported many colorful-leaved tree species from abroad, and some of them had many problems, such as the compound-leaf maple had many pests, and the color and tree shape could not achieve the desired effect. Many color-leaved tree species are restricted by various conditions such as their own cold tolerance, drought tolerance, stress resistance, etc., thereby limiting their promotion. At present, there is an urgent need to select and breed colorful-leaved tree species suitable for my country's native cultivation from native tree species. [0003] Luan tree is an excellent beauti...
