Taxus x media growth is fast, year growth the highest can 60��80cm, increment be domestic Ramulus et folium taxi cuspidatae (China Ramulus et folium taxi cuspidatae, taxusyunnanensis etc.) 3-7 doubly. The Taxus x media planted 3��5 years can gather branches and leaves for refining taxol, and can repeated acquisition per year. Taxol is the diterpene-kind compound with Japanese yew alkene ring extracted from the trunk of Ramulus et folium taxi cuspidatae, bark, branches and leaves, tree root, and its chemical structure is novel, is the important industrial chemicals producing anticancer (tumour) medicine. According to incompletely statistics, the annual ovarian cancer of China, mammary cancer, lung cancer and melanoma patients reach more than 500,000 people, produce the taxol expense needed for cancer therapy drug every year more than 800 kilograms. But, Taxus seeds natural resource are very limited, and since taxol comes out, taxus resource in the world has suffered the destruction of worldwide destructiveness. This grave situation has caused various countries' forestry and the great attention of environment specialist and government. The whole world is all classified as natural Ramulus et folium taxi cuspidatae as rare first class of protection plant in imminent danger, and many national government are taked to limit and forbid to cut down natural taxus resource, and advocate and greatly develop artificial culture. Also there is no large-scale Ramulus et folium taxi cuspidatae artificial growth base on a large scale at present in the world, China only a few family of minority have a small amount of planting base, plant cell culture producer is mainly by producing from external import bark of Ramulus et folium taxi cuspidatae or medicinal extract, output few (about 100 kilograms), can not meet the demand of market and patient far away. In recent years, the medical insurance scheme that China newly puts into effect is determined, and antitumour drug has been listed in essential drugs register, and namely antitumour drug formally enters socialized medicine, considerably increases the consumption of taxol. Taxus x media belongs to shrub type, and germination is strong, and after general afforestation, 3-5 can start beta pruning extraction taxol. Before annual November in autumn to March next year, adopt or a principle adopted gathers according to wheel. Wheel is adopted and is referred to that plantation is full after 3 years, the branches and leaves that circle collection is different per year on trunk. Between adopt and refer to and every two years adopt once, retaining trunk, all the other are all cut.
