Taxus cuspidata, the Japanese yew or spreading yew, is a member of the genus Taxus, native to Japan, Korea, northeast China and the extreme southeast of Russia. It is an evergreen tree or large shrub growing to 10–18 m tall, with a trunk up to 60 cm diameter. The leaves are lanceolate, flat, dark green, 1–3 cm long and 2–3 mm broad, arranged spirally on the stem, but with the leaf bases twisted to align the leaves in two flattish rows either side of the stem except on erect leading shoots where the spiral arrangement is more obvious.
Method for asexually propagating taxus cuspidata
The invention provides a method for asexually propagating taxus cuspidata, relating to the method for propagating the taxus cuspidate. The invention solves the problems of low rooting rate and weak nursery stock in the existing cutting propagation method for the taxus cuspidate and low survival rate under natural condition when the taxus cuspidata is transplanted for afforestation on a mountain. The method comprises the following steps: ears are picked up in winter of the first year, and is buried by ice and snow; in spring of the second year, cutting is carried out on a disinfected cutting bed, a film is coated on the cutting bed in 2.5 to 3 months with humidity of between 85 and 88 percent at the temperature of between 26 and 29 DEG C and shading degree of between 70 and 75 percent after cutting is completed, and the cutting bet is subject to fertilizer application and sterilization; the coated film is removed, cold-proof water is irrigated before winter; and the bed is changed in spring of the third year, and culture is conducted for two years to obtain the taxus cuspidata for afforestation. The cultured sapling has 100 percent of lignification, 80 to 96 percent of cut rooting rate and 85 to 90 percent of planting percentage, thus the mature period of medical forest is shortened. The method can be used for large-scale afforestation.
