Ancient phoebe zherman grafting, breeding and preserving method

Abstract

The invention discloses an ancient phoebe zherman grafting, breeding and preserving method. The method comprises the following steps that firstly, between December and February next year, current-year branches on the middle upper parts of ancient phoebe zherman (more than 200 years old big trees including phoebe chekiangensis and phoebe bournei) are collected before trees bud, after a part of leaves are removed, the branches are moisturized and preserved with wet paper, brought back and stored in wet sand for preservation; secondly, the grafting time is the time when rootstocks start to bud in February and March and scions do not bud; thirdly, current-year pruning branches in a length of about 20 cm are adopted to serve as the scions; fourthly, annual to biennial container-grown seedlings serve as the rootstocks, and grafting is conducted by means of the cut-grafting method; fifthly, after grafting is conducted, the seedlings and the containers are both temporarily planted into soil, and arched sheds are constructed with plastic films covering for moisturizing; sixthly, an observation is conducted once every 7-10 days, the phenomenon that there is water mist or water droplets on the films is taken as a standard, and water is properly sprayed, so that humidness in the sheds is kept. New buds come up in about 30 days, the films on the sheds are uncovered, normal water and fertilizer management is conducted, the grafting survival rate reaches 82%, the length of annual grafted seedlings can reach 30-40 cm, growth is normal, and branches and leaves can keep the characteristics of original plants (ancient phoebe zherman).

Description

technical field [0001] The invention belongs to the field of plant biotechnology, and in particular relates to a method for grafting, breeding and preserving ancient nanmu. Background technique [0002] Phoebe chekiangensis and P.bournei are tall trees belonging to the genus Phoebe in Lauraceae. They are one of the original species of "Golden Phoebe" and have high economic value. They are unique and precious tree species in subtropical regions. Naturally distributed in Zhejiang, Fujian, Jiangxi, Hunan, Hubei, Anhui, Guangxi, Guangdong, Guizhou and other places (Editorial Committee of Flora of China, Chinese Academy of Sciences, 1982; Collaborative Group of Flora of Anhui, 1986). Its trunk is straight and beautiful, and it is a special material for high-end furniture. It is tall and green in all seasons, and it is also an excellent tree species for landscaping. Although Zhejiang Nan and Fujian Nan have high economic and ornamental value, the amount of existing resources is v...

Problems solved by technology

Existing studies only involve the use of Phoebe progeny seedlings for cutting or tissue culture experiments

For hundreds of years old trees and ancient Phoebe trees, their physiological age is large, their flowering and fruiting ability is reduced, and their branches are aging, so it is generally not successful to use them as cuttings or tissue culture materials.
