Zelkova serrata grafting reproduction method

Abstract

The invention discloses a zelkova serrata grafting reproduction method, which comprises the following steps that high-quality lignified or semi-lignified branches on clonal mother trees are adopted as scions, the length of the scions is 8 to 10cm, the scions have two to three buds, and then, the scions are cut into wedge-shaped scions with the length being 3.5 to 4.5cm; proper stocks are adopted, an opening is cut in the center, the cut scions are fast inserted into the opening, after the scion insertion, the contact parts of the scions and the stocks are wrapped out by yellow mud, the buds are avoided during the wrapping, and then, the cut opening parts are sealed through film coating or wax coating. According to the zelkova serrata grafting reproduction method, the zelkova serrata branches or the buds with the good property expression are grafted onto the stocks so that the stocks are heeled and survived into an independent plant. The root systems of the grafting seedlings have the hereditary properties of the stock plants, the trunks and the crowns are the continuation of the growth and the development of the scion stock plants, the characteristics of the stock plants can be maintained, and the hereditary is stable. Through the grafting reproduction technology, good characteristics of good seeds are maintained, the survival rate is improved, and the defects of great scion consumption and long seedling forming time of the grafting reproduction are overcome.

Description

technical field [0001] The invention relates to the field of plant nursery stock breeding, in particular to a method for grafting and propagating beech trees. Background technique [0002] Beech is one of the most important hard broad-leaved native tree species in China's hilly and plain areas. The tree has strong adaptability, beautiful tree shape, early autumn leaf color change period, long ornamental period, beautiful color, smoke-resistant and air-purifying, drought-resistant and barren, and less pests and diseases. It is an important autumn leaf landscape greening tree species in the Jiangnan area. [0003] Due to the excessive development and utilization of resources, the amount of beech resources has decreased sharply and it is in an endangered state. It has been listed as a second-level national key protected wild plant. For this reason, it is imperative to increase seedling breeding efforts and preserve and protect high-quality provenance. At present, seeds are m...

AI Technical Summary

Problems solved by technology

At present, seeds are mainly used for seedling breeding. With the reduction and decline of provenance, seeds are often collected from remaining isolated trees or deformed mother trees in production, resulting in a decline in the quality of collected seeds, and there are obvious differences in the size of beech trees. The phenomenon also makes the production of fine-bred seedlings unable to meet the diversified needs of the market, and it is imperative to preserve and develop fine-bred beech resources.
