Embodiment 1

[0034] A method for cultivating rapid propagation of Davidia involucrata branches, comprising the following steps:

[0035] (1) collecting less than 5 years old, the shoot length is 4~6cm the inveteria involucrata with bud branch is explant material;

[0036] (2) Disinfection and sterilization

[0037] Disinfection and sterilization of shoots with buds (see Table 1 for the sterilization system): cut off the leaves of the shoots with buds, cut into stems with buds, and sterilize the stems with buds. The specific disinfection process is: sterilize with 75% ethanol for 10 ~40s, then wash with sterile water for 2 to 5 times, and then use 0.01% HgCl 2 Soak in the solution for 3-6 minutes, absorb the water, and see Table 2 for the results of disinfection treatment;

Abstract

The invention discloses a cultivation method for rapid breeding of Davidia involucratab branches. The method comprises the following steps: (1) branches with buds of Davidia involucrate are collected as explants; (2) disinfection and sterilization are carried out; (3) branches with buds are induced in order to generate cluster buds, and multiplication culture is carried out; (4) cultivation of strong seedlings is carried out; (5) rooting culture is carried out; (6) seedling exercising treatment and transplanting are carried out; (7) water and fertilizer management is carried out. The method can be used for effectively improving artificial reproduction speed of Davidia involucratab, and improving survival rate of seedlings of Davidia involucratab.

Description

technical field [0001] The invention belongs to the technical field of Davidia involucrata cultivation, and in particular relates to a cultivation method for rapid propagation of Davidia involucrata branches. Background technique [0002] Dove tree (gǒng tóng) is a deciduous tree. It can grow to a height of 15-25 meters. The leaves are broadly ovate, with sawtooth on the edge, and the colorful flowers are beautiful. It is a relic plant left by the Cenozoic Tertiary period 10 million years ago. The tung tree became extinct one after another, and only survived in some areas in southern China. It has become a "living fossil" in the plant world today. It is known as "China's pigeon tree", also known as "pigeon flower tree" and "water pear". It grows in Sichuan Province in southwest China and Hubei Province in central China and surrounding areas. Therefore, Davidia involucrata has been listed as a national first-class key protected wild plant. It is a unique single genus plant i...
