The high branch layering propagation is one of asexual propagation, and is a propagation method of pressing branches on a stock plant into soil or wrapping the branches with soil and the like to form adventitious roots, and then separating the branches above the adventitious roots from the stock plant to form an independent new plant. The layering method is further divided into a low-pressure method for bending and pressing branches into the soil and a high-pressure method for wrapping the branches which are not easy to bend by using a matrix after the branches are cut or girdled. When layering, in order to interrupt the downward transportation of organic substances such as sugar, auxin and other substances from the upper ends of leaves and branches and to make these substances accumulate on the upper part of the treatment for rooting, the cyclic peeling is carried out to promote the rooting at the cyclic peeling position, and after the branch grows new root, the branch is cut off from the mother tree to become new plant. The method is simple, and has the advantages of rapid growth and short seedling time. The method for breeding the seedlings by adopting the layering method has the characteristics of high breeding speed and capability of completely keeping the excellent characters of the parent bodies of the produced seedlings, and is a commonly used seedling breeding method in the production of fruit trees and flowers.
