Seed Seedling technique of Taxus yunnanensis
Taxus yunnanensis (TaxusyunanensisChengetL.K.Fu) is a rare evergreen tree under national first-class protection, which is suitable for growing in the high mountain area of 2000m to 3500m in northwestern Yunnan. Taxol, an expensive anticancer drug, can be extracted from its branches, leaves, bark and roots, so that in recent years, the market of Taxus mairei has been booming and its price has soared. The annual demand of paclitaxel in the world is more than 4800kg, but the actual annual production is only about 250kg. China's Beijing, Shanghai, Liaoning, Yunnan, Sichuan

Problems related to the selection of Taxus varieties
Taxus mairei is now divided into 3 species and 2 varieties, plus a recently introduced new species-Taxus mairei. General taxonomic characteristics of the genus Taxus: we generally classify Taxus on the basis of external morphological characteristics (including leaf shape, leaf length, leaf width, leaf color), seed morphology and leaf anatomy. Rechard also said that the classification of Taxus must be based on the comprehensive study of morphology, anatomy, geographical distribution and depth, but he also said that even so, it could not be completely solved.

How to do well the tending and Management of Taxus mairei Young Forest
Taxus is the most important anticancer plant at the present stage, which is planted in a large area. The method of tending its young forest is briefly introduced. First, shading. Young trees of yew seedlings avoid strong light exposure, and shading must be the key after afforestation. 1. Mountain afforestation. In addition to afforestation under the canopy of sparse woodland, conventional afforestation on barren mountains or reforestation on cutting and burning sites should be planted with fast-growing shade trees at the same time or in the first year, and the interplanting method can be scattered species.

Seedling raising method of Taxus mairei under forest
The scientific and technological personnel of the Forestry Institute of Xinning County, Hunan Province have begun the experimental study on the seedling cultivation of Taxus mairei since 1978, and found out a set of seedling raising method under the pine forest according to local conditions in the scientific experiment, which can effectively save labor and reduce the production cost. It is estimated that raising seedlings under the pine forest per mu can save 40 labourers such as transporting mycorrhizal soil, pulling grass, setting up shade sheds, drought resistance, etc., and saving 1200 yuan on shade shed materials, and the production cost can be reduced by 1500 to 2000 yuan per mu.

High efficiency Seedling raising technique of Taxus mairei
Taxus mairei belongs to Taxaceae, Taxus, evergreen trees. It is an endangered plant in the world and is listed as a national first-class protected tree species. This tree species likes warm and humid climate and is mainly distributed in areas below 1500 meters above sea level in the south of the Yangtze River basin. Ancient trees are scattered in Liandu, Suichang, Qingtian and other places in our city. The material of Taxus chinensis var. mairei is fine-grained, glossy, elastic, purplish red heartwood and strong anticorrosion, so it is a high-class industrial wood. The study found that taxol and taxanins extracted from its bark, roots and leaves, cancer, leukemia, AIDS
