Embodiment 1

[0013] A method for growing seedlings by cuttings of southern yew, the method steps are as follows:

[0014] (1) Preliminary preparations for cuttings: ① Establish a cutting seedbed, build a seedbed with a height of 25cm and a width of 0.8m with bricks, and then level it. Use perlite and Northeast peat ash as the matrix, and perlite and Northeast peat soil according to the mass ratio Mix well at a ratio of 5:2, after mixing evenly, spread the substrate evenly on the seedbed after 2 days of exposure to the sun, with a thickness of 20cm, and sweep it flat; cover shade nets;

[0015] (2) Selection and processing of cuttings: ① Use annual or biennial branches newly germinated at the base of the cuttings, cut them into small sections with a length of 12 cm, leave 2 pinnate compound leaves on the upper part of the small section, and remove all the lower leaves. The age of the cuttings should not be longer than 15 2 years; 2. the processing of cuttings, put the cut cuttings into the...

Embodiment 2

[0019] A method for growing seedlings by cuttings of southern yew, the method steps are as follows:

[0020] (1) Preliminary preparations for cuttings: ① Establish a cutting seedbed, use bricks to build a seedbed about 30cm high and 1.2m wide, and then level it out. Use perlite and northeast peat ash as the substrate, and perlite and northeast peat soil according to the quality Mix well at a ratio of 5:3, mix well and expose to the sun for 3 days, spread the substrate evenly on the seedbed with a thickness of 25cm, and sweep it level; Shed surface covered with sunshade net;

[0021] (2) Selection and processing of cuttings: ① Use annual or biennial branches newly germinated at the base of the cuttings, cut them into small sections with a length of 15 cm, leave 3 pinnate compound leaves on the upper part of the small section, and remove all the lower leaves. The age of the cuttings should not be longer than 15 2 years; 2. the processing of cuttings, put the cut cuttings into t...

Embodiment 3

[0025] A method for growing seedlings by cuttings of southern yew, the method steps are as follows:

[0026] (1) Preliminary preparations for cuttings: ① Establish a cutting seedbed, use bricks to build a seedbed about 28cm high and 1m wide, and then level it up. Use perlite and northeast peat ash as the substrate, and perlite and northeast peat soil according to the mass ratio Mix well at a ratio of 5:3, after mixing evenly, spread the substrate evenly on the seedbed after 2 days of exposure to the sun, with a thickness of 22cm, and sweep it flat; cover shade nets;

[0027] (2) Selection and processing of cuttings: ① Use annual or biennial branches newly germinated at the base of the cuttings, cut them into small sections with a length of 14 cm, leave 3 pinnate compound leaves on the upper part of the small section, and remove all the lower leaves. The age of the cuttings should not be longer than 15 2 years; 2. the processing of cuttings, put the cut cuttings into the indol...

Abstract

The invention relates to a taxus chinensis var. mairei cutting seedling-raising method comprising the following steps: a taxus chinensis var. mairei cutting seedbed is constructed; automatic spraying equipment and a sunshade net are mounted; annual or biennial branches newly germinated from the base are selected, and are cut into small sections with lengths of 12-15cm; 2-3 of pinnate compound leaves are left on the upper part of each small section; the sections are soaked for 2-3h in an indolebutyric acid solution with a concentration of 90-100ppm, and are subjected to cutting insertion; after cutting insertion, the humidity should be maintained at 70-80%, and the temperature is set at 25-28 DEG C; 30-40 days after rooting, the sections are provided with a solution with 0.15-0.25% urea and 0.2-0.3% potassium dihydrogen phosphate. The method is simple, and has high operability and low cost. With the method, the taxus chinensis var. mairei rooting rate is high, and cutting seedling-raising effect is significant. The method facilitates development and utilization of taxus chinensis var. mairei.

Description

technical field [0001] The invention relates to a cutting seedling raising method of southern yew, belonging to the technical field of planting and seedling raising. Background technique [0002] Yew, also known as yew, has eleven varieties in the world. In my country, there are five varieties of Yunnan yew, Tibetan yew, Northeast yew, Chinese yew, and southern yew. Southern yew is usually sexually propagated, but because it is dioecious, it is not easy to produce seeds, and the dormant period of the seeds is as long as more than 1 year. Even after technical treatment, its germination rate and emergence rate are still low, which gives sexual Breeding has brought certain difficulties, and at the same time the growth of sexually propagated seedlings is slow, which has brought many adverse effects to the development and utilization of the southern yew resources. Contents of the invention [0003] The object of the present invention is to solve the shortcoming of low surviva...
