Abstract

The invention discloses a cultivation method of yew, which comprises the following steps: (1) selection of a seedling-raising site; (2) preparation of the ground for bed; (3) harvesting of seeds; (4) storage of seeds; (5) treatment of soaking seeds; 6) Sowing period; (7) Fertilizer and water management; (8) Prevention and control of diseases and insect pests; (9) Transplanting and planting; (10) Young forest tending. The beneficial effect of the present invention is that: the present invention obtains yew seedlings through sexual seed breeding and propagation, and then obtains large yew seedlings and saplings after transplanting and planting, so as to expand the cultivation area of ​​southern yew. Adopting the proprietary cultivation and management measures of the southern yew, establishing the southern yew propagation and transplanting technology system, making the large-scale industrial production of the southern yew possible, so as to meet the market's demand for the southern yew and provide protection for endangered wild plant resources a good test system. This method is sexual reproduction, which can improve the variety of yew and increase the survival rate.

Description

technical field [0001] The invention relates to a cultivation method of yew. Background technique [0002] Yew, also known as yew, is a relict plant of Quaternary glaciers. It is called the "living fossil" in the plant kingdom. Because of its scarce resources, it is listed as a rare tree species in the world for protection. Paclitaxel, one of the three major anticancer drugs in the world, is mainly isolated and extracted from the bark of yew trees, which are more than 30 years old, to be of development value. At present, the international demand for it is still quite large, and the extraction of paclitaxel from the bark leads to a large number of felling of yew trees, which poses a threat to the species protection and regional distribution of yew plants, and will eventually destroy the ecological environment and cause Depletion of wild resources and extinction of species. Traditionally bred yew has a low survival rate and is now an endangered species. [0003] Existing br...
