Problems solved by technology

However, the content of effective products in the branches and leaves of common yew is very low (Taxol content 0.001~0.01%; 10-DABⅢ content 0.01~0.1%), and, because most enterprises only pay attention to the expansion of planting and processing scale and despise the research on planting quality (variety Breeding, cultivation technology research, etc.), resulting in very low or only a small amount of taxanes in the planted yew branches and leaves
Because the product content in the root bark is 2-5 times higher than that in the branches and leaves, some enterprises can only dig the whole plant for processing after planting or try to smuggle natural yew bark from various places as raw materials to maintain their survival, forming a short-term vicious competition and Great waste of scarce resources

Embodiment 1

[0030] A method for improving product content in yew branches and leaves, the method may further comprise the steps:

[0031] (1) Tree preparation: In the spring of each year, when the soil is moist after the rain, the planting density is 200-300 trees / mu, the size of the hole is 40㎝×30㎝×30㎝, and the shading degree is 50%-70%. Planting yew raw material forest, standby;

[0032](2) Pruning of branches and leaves: in autumn and winter every year, before the yew trees germinate, the yew trees that have been artificially planted for more than 2 years are cut and trimmed to a height of 50-100 cm and the branches are pruned. 1 / 3 to 1 / 2 of the total length of the branches before pruning; only the branches will be pruned from the next year. When pruning yew branches, they should be pruned into a round head shape as a whole. At the same time, the tending and fertilizer and water management of yew during the growth period should be strengthened to increase the number and area of ​​new ...

Abstract

The invention discloses a method for improving the product content in taxus chinensis branches and leaves, and relates to the technical field of medicinal taxus chinensis cultivation. The technical key point comprises the following steps: (1) forest woods are prepared; (2) branch and leaf pruning is carried out, wherein taxus chinensis trees artificially planted for more than 2 years are pruned for shaping; tending and fertilization are enhanced, such that bud proliferation and growth are promoted, and taxus chinensis new leaf number and area are improved; (3) biological induction is carried out, wherein when leaves attached to new branches are 45-55% expanded, the leaves are sprayed with a prepared bioactive induction solution once or twice; and (4) harvesting and utilization are carried out, wherein all the new branches and leaves of taxus chinensis are lignified, the branches and leaves are picked, processed and utilized. The invention aims at providing the easy-to-operate, practical and highly efficient method for improving the effective product content in artificially cultivated taxus chinensis branches and leaves. The method is used in planting management of an artificial taxus chinensis raw material forest for preparing medicinal compounds.

Description

technical field [0001] The invention relates to a method, more specifically, to a method for increasing the content of effective products in the artificially cultivated yew branches and leaves. Background technique [0002] Taxus (Taxus L.) is an evergreen tree of Taxus genus Taxus, its bark or branches and leaves contain a variety of chemical components of taxanes with high commercial value, such as the secondary metabolite of Taxus plant paclitaxel ( Taxol) and 10-deacetylbaccatin Ⅲ (10-DAB Ⅲ), among which paclitaxel is an anticancer drug with good activity, and has obvious curative effect on ovarian cancer, breast cancer, non-small cell lung cancer, etc.; Another taxane product 10-DABⅢ is the precursor of artificially synthesized paclitaxel, and is also the main raw material for the production of highly effective anticancer drug docetaxel. [0003] The yew plant (Taxus species.) is a national first-class protected tree species. There are 4 species and 1 variety in my cou...
