At present, there are no large-scale yew artificial planting bases in the world, and only a few in my country have a small amount of planting bases. Paclitaxel manufacturers mainly rely on the production of yew bark or extract from abroad, and the output is very small (about 100 kg) ), far from meeting the needs of the market and patients

Embodiment 1
[0027] From November to March of the next year, choose an altitude between 800 and 1800 meters, annual rainfall above 1000mm, temperature below 35°C, air humidity above 82%; slope below 35 degrees, soil thickness above 50 cm, pH The value is between 5 and 6, the soil quality is loose, the water is filtered, the air permeability is good, the content of gravel is small, and the 2-year-old Mandia yew is planted in the sandy soil without water accumulation or in the sandy loam block, and the branches and leaves are collected as normal Pruning, and then raising seedlings on the spot.
[0028] 2. Cut off the main root and 30% of the aged fibrous roots of the yew seedlings, collect the cut roots, clean them, and dry them with the branches and leaves. Then spray the pruned roots with an aqueous solution of 800 mg / L (alpha-naphthylic acid needs to be dissolved in alcohol first) with α-naphthyl acetic acid, it is advisable to spray wet without dripping.

Abstract
The invention provides a culture and collection method capable of improving Taxus media biomass. The culture and collection method is characterized by repeating to perform autochthonous transplanting of Taxus media and collecting roots and leaves thereof every year and cutting off principle roots while spraying rooting agent during transplanting. By the culture and collection method, since the Taxus media losses the principle roots completely, fibrous roots thereof become stronger, regeneration capacity is improved, and the biomass of single plant collected each year can be increased by at least 10% as compared with the conventional value. The biomass of the Taxus media includes an underground part and an aboveground part, the underground part refers to the biomass of roots and the aboveground part mainly refers to the biomass of branches and leaves; the biomass of the underground part, the aboveground part and the collection part respectively accounts for one third. Paclitaxel content of roots of the Taxus media is at least three times of that of branches and leaves, thus yield of products such as paclitaxel can be increased by 20-30% as compared with the conventional yield, shortage of paclitaxel resources can be relieved, more raw materials can be obtained by utilization of limited resources, unit plant cost is lowered, production cost is lowered further, and economic benefit, social benefit and ecological benefit are remarkable. Besides, by means of repetition of autochthonous transplanting every year, preserving rate of raw Taxus media is guaranteed, weak plants can be changed and after-culture can be carried out in time, and yield stability of raw material in unit area is guaranteed.
Description
technical field [0001] The invention relates to a method for cultivating and collecting yew, in particular to a method for cultivating and collecting the biomass of yew mandia. Background technique [0002] Mandia yew (Taxusmadia) is native to the United States and Canada. It is a natural hybrid variety. Its female parent is Northeast yew (T.cuspidata) and its male parent is European yew (T.bauata). The growth and development of Canada has a history of nearly 100 years. It was introduced from Canada in the mid-1990s in my country. Taxus Mandia is an evergreen shrub with huge biomass and short growth period. Its main root is not obvious, the lateral roots are well developed, the branches and leaves are lush, the germination is strong, and it is resistant to pruning and low cold. It can be planted in most parts of the country. Taxus mandia contains paclitaxel in every part of the plant, its content is 8-10 times that of other yews in China, the content of branches and leave...
