Abstract

The invention relates to a Taxus media cuttage method. The Taxus media cottage method is characterized by comprising the following processing steps that a place which is flat, sheltered, sufficient in water source, little in light and convenient to manage is selected to serve as a cuttage land; a cuttage bed is built by bricks on the periphery of the cuttage land, the cuttage bed is higher than the ground, and cuttage ground substances in the cuttage bed are formed by mixing perlite and turfy soil; half-lignification branches which grow in the current year and are on seed trees are collected and manufactured into cuttings, wherein the seed trees are free of plant diseases and insect pests and grow strongly, and complete sections with leaf branches are reserved at the upper portions of the cuttings; the cuttings are inserted into the cuttage ground substances in the density of 5*6cm, the insertion depth is 1/3-1/2 of the length of the cuttings, the cuttings make close contact with the cuttage ground substances, one cutting is watered every time the cutting is inserted, and a plastic arch shed covers the cuttings to shade the cuttings; strict control over moisture management, air humidity management, temperature management and seedling stage management is carried out after cuttage of the cuttings is finished. The rate of cuttage survival can reach 90%.

Description

technical field [0001] The invention relates to a cutting method of yew mandia, belonging to the technical field of agricultural plants. Background technique [0002] Mandia yew (Taxus media) is a natural hybrid discovered in the United States in 1918. Its female parent is Northeast yew (T. cuspidata) and its male parent is European yew (T. baccata). Afterwards, more than 10 strains of Taxus chinensis were bred through artificial hybridization in various places. Among them, the Taxus media CV Hicksii variety bred by Henrg Hicksii is currently the most cultivated variety in many countries such as the United States and Canada. my country introduced this variety in 1996. American Mandia yew is known as "plant gold". According to the annual output of 750kg / hm 2 Calculated as dry raw materials, about 10g of paclitaxel can be extracted. Based on the wholesale price of 146.1 US dollars per 20mg vial of paclitaxel injection currently on the market, the total value can reach 48,7...
