Problems solved by technology

[0003] The existing breeding of southern yew is generally propagated by cuttings, and it is difficult to take root after the cuttings are cut during the propagation process, the survival rate is very low, and the variety has not been improved, but simply reproduced and propagated

Embodiment

[0041] Southern yew can be sexually propagated through seedlings to expand the cultivation area.

[0042] 1. Selection of seedling sites

[0043] Choose a shady or semi-shady slope with a slope of 5° to 15°, gentle mountainous land, good soil water and fertilizer conditions, convenient transportation, sufficient water source, and easy management as a place for seedling cultivation.

[0044] 2. Make a bed

[0045] Raised seedlings are raised in high beds, the bed surface is 10-30m long, 1.2-1.5m wide, 20-30cm higher than the walkway, and 30-50cm walkway. The bed surface is flat and solid, and the direction of the bed is preferably north-south. Drainage ditches are dug around the nursery ground so that the internal water does not accumulate and the external water does not flood. The seedbed is mixed with 70-80% of vegetable garden soil or humus soil and 20-30% of sand to form a matrix soil with loose structure, good air permeability, water and fertilizer retention, and the de...

Abstract

The invention provides a method for breeding and cultivating taxus mairei with a seed, and the method comprises the following steps that a taxus mairei seedling is obtained by breeding and cultivating the sexual seed; the taxus mairei seedling is transplanted and planted, and a large taxus mairei seedling and a young tree are obtained; and the cultivation area of the taxus mairei is expanded. Special cultivation management measures for the taxus mairei are adopted to establish a taxus mairei breeding and cultivation technical system, a manual way to breed the taxus mairei is opened up, so that the large-scale industrial production of the taxus mairei becomes possible, the market demand for the taxus mairei is met, and a good test system is provided for protecting endangered species of wild plant resources.

Description

technical field [0001] The invention belongs to the propagation and cultivation technology of the southern yew, and specifically provides a method for the propagation and cultivation of the southern 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...
