Cutting nursery method for taxus media

Abstract

The invention discloses a cutting nursery method for taxus media. The method comprises the following steps: selection of nursery stock: selecting garden soil and humus soil with the volume ratio being1:1 or selecting garden soil, perlite and river sand with the volume ratio being 2: 1: 1 as a nutrient substrate, separately sieving, adding 50% of carbendazim and wet powder and 600 times of aqueoussolution, or adding ferrous sulfate powder with the ratio being 50: 1, and fully mixing to obtain a substrate pile with the humidity being 60%; covering the outside of the substrate pile with plasticcloth, compacting the periphery of the plastic cloth, and using the substrate pile 10-20 days later; and cutting. By the cutting nursery method for taxus media, the rooting speed can be increased effectively, a rooting period which lasts for 5-7 months generally is shortened to be 3-4 months, the rate of survival of the nursery stock is increased to be 95%, the growth speeds of the nursery stockare close, the number of fibrous roots is increased to be 5-8, a root system is lengthened, the adaptive capacity is good, and the stress resistance and the drought resistance are improved.

Description

technical field [0001] The invention belongs to the technical field of yew cultivation, and in particular relates to a cutting seedling raising method of yew mandia. Background technique [0002] Mandia yew (Taxus media), belonging to Taxaceae Taxus, is a natural hybrid, its female parent is Northeast yew (T.cuspidata), and its male parent is European yew (T.baccata). Shrub, evergreen in all seasons, not obvious tap root, well-developed lateral roots, lush leaves and branches, strong germination, pruning resistance, cold resistance, and can grow in various climates and soil conditions. Paclitaxel extracted from yew is "currently the only botanical drug that can curb the growth of cancer cells". It is known as the "golden tree" and has become the most expensive medicinal tree species in the world. Wild yew resources are scarce in the world today. Diterpenoids with high anticancer activity can be extracted from its bark, roots, leaves, and stems, which can treat various disea...
