Method for breeding yew

Abstract

A yew breeding method comprises the steps as follows: yew seeds with dry husk are scrubbed with washing powder water until the seed tips become dim gray, and rinsed clean with clean water, placed in warm water at the temperature of 60-70 DEG C for 10-30 minutes, put in wet sand for storage, and sowed for breeding in the seeding period. The sowing ground is covered with a layer of firewood or curly tree leaves, the temperature of the sowing ground is kept at 10-20 DEG C and the soil moisture is kept at 13-30%. The breeding method of the invention effectively solves the present situation that the yew breeding fails and the survival rate is low; and the breeding method causes the seedling emergence rate to reach more than 65% and the survival rate to be more than 70%.

Description

technical field [0001] The invention relates to a cultivation technology of yew, in particular to a breeding method for improving the survival rate of yew. Background technique [0002] Yew, commonly known as yew and yew, is a shallow-rooted plant. It is a "relict" left over from the end of the Tertiary to the beginning of the Quaternary. It has a history of 2.5 million years and is recognized as an endangered species in the world. Natural and rare tree species are also precious anti-cancer plants, which integrate medicinal, material and ornamental uses, and have extremely high development and utilization value. Paclitaxel extracted from its roots, stems and leaves is an internationally recognized anti-cancer drug, which is expensive. Due to the slow growth rate of yew under natural conditions, poor regeneration ability, and low survival rate of breeding, yew has not been artificially planted in large areas so far, and its medical value cannot be fully utilized.
