Embodiment 1

[0029] A breeding method of Chinese yew, comprising the steps of:

[0030](1) Collection of cuttings: In Dayao Mountain, Jinxiu County, Guangxi, wild yew trees older than 100 years were selected, and healthy new shoots were intercepted, and the indoor humidity was kept at 60-70% and placed in the dark for 72 hours to remove tender shoots. branch fat, and then use sterilized scissors to intercept 10-12cm semi-lignified shoots as cuttings.

[0031] (2) Treatment of cuttings: Cut the base of the collected cuttings into a horseshoe shape with a slope length of 0.5cm, soak the formed slope in mercuric chloride solution for 3~5s for disinfection treatment, after natural air drying, sterilize with a garlic oil solution with a concentration of 30ppm , not sealed with wax, preserved with nutrient solution, for later use.

[0032] (3) Seedbed: The seedbed matrix is ​​composed of river sand, loess, vermiculite and γ-polyglutamic acid at a ratio of 2:3:2:0.005. After the seedbed matrix i...

Abstract

The invention discloses a breeding method for Chinese Jinxiu yew. The method comprises the following steps of 1 cutting slip collecting, 2 cutting slip treating, 3 seedbed treating, 4 cuttage, 5 final-period management and the like. Before cuttage, cutting wood oil is removed at first, in the cutting slip storage process, no traditional waxing method is adopted, and a specially made nutrient solution is adopted for storage, so that the cuttage survival rate is greatly increased; the nutrient solution is prepared from 0.1-0.25 mg/L gamma-polyglutamic acid, 5-8 g/L of alginic acid, 0-15 g/L of MS culture medium, 5-8 g/L of diammonium phosphate, 0.5-0.8 mg/L of amino-oligosaccharin, 0.05-1.0 g.L of pyraclostrobin, 0.01g/L of polyvinyl alcohol and the balance purified water, wherein all the components account for 1 L. Due to the cuttage method, the survival rate of seedlings of the wild Chinese yew in the Jinxiu county is 95% or above, the survival rate of transplanting after outplanting is 85% or above, and the method has the great value for prolonging the life of precious species resources.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a propagation method of Taxus chinxiu. Background technique [0002] Yew (Latin name Taxus chinensis (Pilger) Rehd.) is a species left over from Quaternary glaciers. It is known as the "living fossil" of the plant kingdom. It is a rare and endangered plant in the world. At present, it is mainly found in Guangxi and Yunnan, and a few are found in mountainous areas. Jinxiu Yao in Guangxi Zhuang Autonomous Region Dozens of ancient trees more than a thousand years old were found in the primitive deep mountains of the autonomous county, which are extremely precious, and are listed as first-class protected plants in my country. When the yew fruit is ripe, the red fruit is full of branches, which is gorgeous and colorful. It is named for its resemblance to the "Acacia Bean" in the south. It is not only an important timber tree species and ornamental tree species, ...
