If the large ash plantation base uses the tree nutrition method of trees and shrubs to cultivate ash, it can usually be called a vegetative propagation method, or it can be said to be a vegetative propagation method. The use of cuttings, ramifications, layering and other methods to cultivate ash can be called self-rooted seedlings, and ash grafted and propagated by ash is called ash grafted seedlings, but it is a vegetative propagation seedling.
These methods are the large pewter planting base using the plant's regenerative ability and meristem ability to reproduce with other plants by grafting. From the point of view of advantages, it is conducive to the reproduction of excellent varieties. When using forest seeds for reproduction, there will be many excellent instability due to the separation of shapes and other reasons. It is impossible to preserve the inherent excellent characteristics of the mother. The method of vegetative reproduction is one of the main methods for breeding of fine varieties. It reproduces by using the plant's regenerative ability, meristematic ability, and the affinity of joining with another plant through ash grafting. White wax grafted cuttings, strips, ramets, and roots for propagation. The method is simple, and the application is also extensive. Therefore, the growth rate of ash is also very fast. In the early stage of planting, the growth rate of seedlings is also very rapid.
