Taxus media cultivation method

Abstract

The invention relates to a Taxus media cultivation method which comprises the following steps: (1) preparing before planting, (2) planting tree seedlings and (3) field management. The step (1) includes the following steps: selecting a cultivation field, and selecting cultivation seedlings. The step (2) includes the following steps: in March or April, planting the cultivation seedlings into the cultivation field with the row spacing and line spacing respectively of 55-65 cm, enabling soil moisture content in the cultivation field to be 30%-40%, and ensuring survival of cultivation seedlings to form small trees. The step (3) includes the following steps: weeding; conducting one-time topdressing to all small trees in April or May each year from the next year when planting is completed, concretely, topdressing bio-organic fertilizer 90-100 g, and topdressing compound fertilizer 50-60 g; spraying plant growth regulators to all small trees in April or May each year from the next year when planting is completed; and collecting new branches and leaves of the small threes in October or November each year from the next year when planting is completed, wherein the new branches and leaves are grown in the current year. By means of the Taxus media cultivation method, the cultivation seedlings can reliably survive, fast grow, and stably accumulate valid biomass.

Description

technical field [0001] The invention relates to plant cultivation, in particular to a method for cultivating Taxus Mandia. Background technique [0002] Paclitaxel is a compound extracted from the yew plant. It is mainly suitable for the treatment of ovarian cancer and breast cancer, as well as lung cancer, colorectal cancer, melanoma, head and neck cancer, lymphoma, brain tumor, etc. One of the most effective new anti-cancer drugs, the total effective rate is over 75%. At present, the raw material of paclitaxel is mainly the bark of yew. Because the bark of yew is a non-renewable resource, the raw material of paclitaxel is very limited; in addition, yew is recognized as an endangered natural and rare anti-cancer plant in the world. , under natural conditions, the growth rate is slow and the regeneration ability is poor. There is no large-scale yew raw material forest base in the world. China has listed it as a first-class rare and endangered plant, and the United Nations h...
