Method for grafting summer gold gingko in garden landscaping project

Abstract

The invention relates to a method for grafting a summer gold gingko in a garden landscaping project. The method comprises the following steps of 1, scion grafting preparation: after defoliation of the summer gold gingko in late autumn or before flowing of sap in early spring, selecting one-year to two-year branches which are free of disease, grow strongly and develop fully to serve as scion grafting objects during scion grafting preparation; 2, stock preparation: selecting a gingko which grows strongly, is rich in crown and is provided with more branches on main branches and dense slender branches on the branches as the stock; 3, trimming: trimming to form a tree-shaped profile according to the garden project design requirements; retaining at least 2 / 5 untrimmed secondary branches on each main branch, and trimming the other secondary branches to reserve the length of 5-10cm for grafting use; 4, grafting: adopting a generally adopted cut-grafting method. The method fundamentally solves the problem that garden new varieties are slowly applied to the garden landscaping, and also fundamentally solves the problems that leaves of the summer gold gingko are lower in chlorophyll content, thus the photosynthesis is weaker, and accordingly trees grow poorly, and the like.

Description

technical field [0001] The invention relates to the field of landscaping, in particular to a method for grafting new ginkgo varieties, in particular to a method for grafting Xiajin ginkgo in landscaping projects. The method of the invention is suitable for directly grafting the freshly planted common ginkgo after pruning, so that the effect of coloring and greening can be achieved in the same year. Background technique [0002] Ginkgo, also known as "ginkgo tree", "Gongsun tree", gymnosperm, Ginkgoceae, is the oldest relic plant in the existing seed plants, and is a historical heritage and living fossil (Darwin, C); it is a unique precious tree species in my country. It is the essence of history, an eternal symbol, a world natural heritage unimaginable by human beings, and a milestone that reveals the mysteries of nature. [0003] Ginkgo biloba is a deciduous tree with a height of 30-40 meters. The branches are both long and short. The leaves are fan-shaped and dioecious. Th...

Problems solved by technology

This grafting method not only increases the cost of production management, but also takes a long time to apply to the project

In addition, after pruning all the ordinary ginkgo leaves and then grafting new varieties of Xiajin Ginkgo, it may also cause the phenomenon of "little old trees" of Ginkgo due to the low chlorophyll content in the leaves of Xiajin Ginkgo and weak photosynthesis.
