Problems solved by technology

[0004] The survival rate of the seedlings cultivated by the traditional technology of cultivating Taxus Mandia in my country is low, and the variety is impure, which affects the content of paclitaxel and restricts the growth rate
At the same time, due to the low survival rate of reproduction, the cost of raising seedlings is high

Abstract

The invention relates to the taxus media culture technology, which belongs to the sticking culture technology. The taxus media culture technology comprises branch selection, nutrient solution soaking and soil sticking culture. The branch selection technology obtains the easiest surviving sticking branch selection standard of the taxus media, the selected and stuck branch soaking nutrient solution recipe and the environment conditions of the sticking soil substrate are very suitable for the survival of the taxus media. When the technology of the invention is used for propagation, the survival rate higher than 90 percent can be reached.

Description

technical field [0001] The invention relates to a cultivation technique of the Mandia yew, in particular to a cultivation technique for improving the survival rate of the Mandia yew. Background technique [0002] Yew, also known as yew, has a history of 2.5 million years on the earth. It is a rare and endangered plant in the world left over from Quaternary glaciers. It is rarely distributed in the world. It has been listed as a national first-class key protected plant by countries all over the world. . Paclitaxel contained in yew has a unique anti-cancer mechanism and high anti-cancer activity, which can prevent the proliferation of cancer cells and inhibit the migration of tumor cells. It is recognized as the most important anti-cancer active substance in the field of natural medicine today. Demand for the drug outstrips the tree's production capacity. At present, about 6.3 million patients die of cancer each year in the world, and about 1500-2500 kg of paclitaxel is cons...
