specific Embodiment approach 1

[0006] Specific embodiment one: the method for the vegetative propagation of the Northeast Taxus of the present embodiment is carried out by the following steps: one, fringe selection: in the winter of the first year, in the middle and upper part of the Northeast Taxus tree crown, cut and gather 1-3 years to grow all The lignified branches are used as cutting spikes, which are buried in ice and snow for later use; 2. Cutting bed production: in the spring of the second year, the mass ratio of humus soil to river sand is 1: 1.4 to 1.6. Mix the river sand evenly, and after disinfection and insecticide treatment, make a cutting bed with a width of 0.9m to 1.2m and a thickness of 0.25m to 0.30m in the greenhouse or on the open field; The bar ear that collects is cut into length and is 10cm~15cm, the cutting ear of basal part diameter ≥0.2cm, and cutting ear has 1 terminal bud or short side bud, then handles with hormone; Spray the cutting bed with potassium permanganate solution, s...

specific Embodiment approach 2

[0009] Embodiment 2: This embodiment is different from Embodiment 1 in that: the diameter of the river sand described in step 2 is 1 mm to 0.1 mm. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0010] Embodiment 3: This embodiment is different from Embodiment 1 in that the diameter of the river sand described in step 2 is 0.8 mm to 0.3 mm. Others are the same as in the first embodiment.

Abstract

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.

Description

technical field [0001] The invention relates to a method for breeding Northeast yew. Background technique [0002] Northeast Taxus, also known as Taxus, is a rare tree species of Taxaceae. Its stems, branches, leaves, and roots can be used as medicine. The main components are paclitaxel, taxine, and diterpenoids, which have anti-cancer functions. , and has the effect of inhibiting diabetes and treating heart disease. In addition, the seeds can also be used to extract oil. Because the northeast yew is an endangered medicinal tree species, dioecious, and scattered, it is difficult to collect seeds and the seed emergence rate is low, and it is difficult to meet the needs of large-scale breeding; the Chinese patent with the publication number CN1745619A discloses a yew tree The cultivation method of this method is to cut off the branches of the plants during the Qingming and Liqiu solar terms, trim them into sections of 10cm to 20cm, remove the lower leaves, soak them in the ro...
