This method is limited by conditions such as time and place, and the resources of yew seeds in our country are limited. The country prohibits picking wild yew seeds to protect the existing yew resources, so it cannot be reproduced in large quantities.
[0008] 2. Cutting propagation: the survival rate of conventional cutting propagation is only about 3% to 20%, which is a waste of resources
[0009] 3. Tissue culture propagation method: demanding conditions, strong technicality, very low success rate, not conducive to promotion
[0010] It can be seen that the above methods are difficult to achieve the goal of saving yew resources and producing yew seedlings on a large scale and industrialized

example 1
[0058] 1. Preparation work:
[0059] (1) Build a plastic greenhouse with steel structure: Choose a sunny, wind-shielded, dry, well-drained place to build a shed without soil infectious diseases, choose a professional team for design and construction, with an area of 2000m 2 Left and right, 32m in length and 65m in width, the irrigation water pipes are pre-buried, the ground of the greenhouse is leveled, and the cement is poured.
[0060] (2) Prepare the seedbed: the width of the seedbed is 1.2-1.5m, the length is 15m, surrounded by bricks (or the prefabricated section is trapezoidal: the lower bottom is 8cm, the height is 15cm, the upper bottom is 5cm, and the length is 200cm. 15cm, leave a 30-40cm walkway between the beds, and after the seedbed is completed, put 3-6cm thick pebbles to facilitate drainage.
[0061] (3) Preparation of pretreatment liquid and rooting liquid: the pretreatment liquid is 1000ppm IBA; the rooting liquid is 1000ppmNAA.
[0062] (4) Preparation of...

[0084] Same as Example 1, the difference is:
[0085] 1. Preparation of pretreatment liquid and rooting liquid: pretreatment liquid is 1000ppmIBA; rooting liquid is 1000ppmNAA.
[0086] 2. Prepare the nutrition bag: mix the yellow heart soil and humus soil in a ratio of 3:1, pour it into a 7×11cm flat plastic bag, pour the nutrition solution into the nutrition bag, and then place the nutrition bag on the seedbed for later use.

[0088] Same as Example 1, the difference is:
[0089] Prepare the nutrition bag: Mix the yellow heart soil and sawdust in a ratio of 3:2, pour it into a 7×11cm plastic flat bag, pour the nutrition solution into the nutrition bag, and then place the nutrition bag on the seedbed for later use.

Abstract
The invention discloses a method for rapidly propagating taxus chinensis seedlings, and the method comprises the steps of preparing nutrient soil, nutrient solution, pretreatment solution and rooting solution by using a plant tissue culture principle; filling the nutrient soil into a nutrient bag; drenching the nutrient soil in the nutrient bag by using the nutrient solution; taking a taxus chinensis semi-lignified twig as a propagation material; shearing the taxus chinensis semi-lignified twig into bud-containing subsections which are 0.5-12cm long; inserting the bud-containing subsections into the nutrient bag after being treated with the pretreatment solution; one week later, spraying the rooting solution which is diluted by 1000-1200 times for promoting the rooting; and spraying once every week until the rooting is finished. Through culture and management for 3-4 weeks, the bud-containing subsection roots become a new plant, the survival rate is above 90% and the root system is well developed. The method provided by the invention has the following advantages of being simple for operation, easy for grasping, feasible in four seasons and beneficial for popularization, well solving the technical problem of rapidly propagation of taxus chinensis seedlings, realizing industrial seedling culture, and being conducive to protecting the precious wild taxus chinensis resources of China.
Description
technical field [0001] The invention belongs to the field of rapid propagation of plants, in particular to a method for rapid propagation of yew seedlings. Background technique [0002] Yew (Taxus) is recognized as an endangered natural and rare anti-cancer plant in the world. It is an ancient tree species left over from Quaternary glaciers and has a history of 2.5 million years on the earth. China has listed it as a first-class rare and endangered plant, and the United Nations has also banned its logging. [0003] Yew is suitable for planting in all parts of the north and south. It has the characteristics of shade-loving, drought-tolerant, and cold-resistant. It requires a soil pH value of 5.5 to 7.0. It can be interplanted with other tree species or orchards, and its management is simple. It not only has well-developed lateral roots, luxuriant branches and leaves, and strong germination ability, but also has a wide range of climate adaptability, wide requirements on soil ...
