Problems solved by technology

Among them, the seedlings cultivated by the traditional technology of Taxus Mandia in my country have low survival rate and impure varieties, which affect the content of paclitaxel and restrict the growth rate.
At the same time, due to the low survival rate of reproduction, the cost of raising seedlings is high, which directly affects the production and economic benefits of the yew industry

[0022] The first embodiment of a kind of Taxus Mandia cultivation technology of the present invention is as follows:

[0023] It is a cutting cultivation technology, including branch selection, soaking in nutrient solution and soil cutting cultivation. The branch selection technology is as follows: divide the yew branches into nuogan sections, and use their regeneration ability to cut each section of yew branches. Treatment, let the yew branches take root and germinate; the following factors should be considered in branch selection: young trees under 5 years should be selected; The bottom diameter is 3mm; the cuttings cut according to the above specifications are bundled into small bundles every 30 pieces, so that the lower cuts are even and the upper cuts are uneven;

[0024] The bundled branches were soaked in the nutrient solution for 48 hours, and the formula of the nutrient solution was as follows:

[0025] Sodium hydroxide 1.00g / L

[0026] β-Naphthylacetic acid 10.00g / ...

Abstract

The invention relates to a cultivation technology for Taxus media. The cultivation technology comprises branch selection, soaking of branches in nutrient solutions and cuttage cultivation in soil, to be specific, cutting Taxus branches into a plurality of sections, performing cuttage treatment on each section of Taxus branch to enable the Taxus branches to take root and sprout by using the regeneration capacity, wherein the length of each cutting is 10-15cm, and the bottom diameter of each cutting is 3-5cm; bundling up every 30 cuttings cut according to the specifications into one small bundle, and enabling lower cuts to be even and upper cuts to be uneven; soaking bundled branches in the nutrient solutions for 48 hours. According to the cultivation technology for the Taxus media, easy-to-survive cuttage branch selection standards of the Taxus media are achieved, and the selected formula of soaking cuttage branches in the nutrient solutions and the environmental condition of transplant soil matrix are quite suitable for survival of the Taxus. The survival rate of the Taxus can reach above 90% through the cultivation technology for the Taxus media.

Description

technical field [0001] The invention relates to the field of planting, in particular to a cultivation technique of Taxus chinensis. Background technique [0002] Yew is a shallow-rooted plant with inconspicuous main roots and well-developed lateral roots. It 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. It has been around for 2.5 million years history. Due to the slow growth rate and poor regeneration ability of yew under natural conditions, there has not been a large-scale yew raw material forest base in the world for a long time. China has listed it as a first-class rare and endangered plant, and the United Nations has also banned its logging. Among them, the seedlings cultivated by the traditional technology of Taxus Mandia in my country have low survival rate and impure species, which affect the content of paclitaxel and restrict the growth rate. At the same time, due t...
