Problems solved by technology

[0009] The technical problem to be solved by the present invention is aimed at the defects that the content of paclitaxel and other taxane compounds in the artificially planted yew in the prior art is very low, and the cost of processing and extracting paclitaxel and other taxane compounds is very high, A method for planting yew and the application of 5-aminolevulinic acid as a yew fertilizer are provided, and it is unexpectedly found that the content of paclitaxel and its derivatives in the yew planted by this method is greatly improved, and the effect is remarkable.

Embodiment

[0037] 1. Cultivation and fertilization plan

[0038] In the field experiment area in 2006, 8 plots (25 plants per plot) were artificially planted for 1-year-old Chinese yew seedlings, and each plant was applied with 25g of different concentrations of 5-ALA fertilizers in March and August each year, respectively. : no fertilization, compound fertilizer (containing 0.5% 5-ALA by mass ratio)), compound fertilizer (containing 1% 5-ALA by mass ratio), compound fertilizer (containing 2% 5-ALA by mass ratio), Applying organic fertilizer (containing 1% 5-ALA by mass ratio), applying nitrogen fertilizer (containing 1% 5-ALA by mass ratio), applying potassium fertilizer (containing 1% 5-ALA by mass ratio), and applying phosphorus fertilizer (containing 1% 5-ALA by mass ratio) 1% 5-ALA). The fertilization time, fertilization frequency and fertilization amount are the same. The content of paclitaxel was measured in September of 2007, 2008, 2009 and 2010 respectively.

Abstract

The invention discloses a planting method of taxus chinensis and applications of 5-aminolevulinic acid serving as fertilizers of the taxus chinensis. The planting method comprises the steps of planting and fertilizing the taxus chinensis according to regular manual planting methods in the field, wherein the fertilized fertilizers contains 0.1-10% of 5-aminolevulinic acid, and the percentage is mass percentage of the 5-aminolevulinic acid occupied in total weight of the fertilizers. Taxol content and derivative conetent of the taxol in the taxus chinensis planted by using the method is greatly improved, and effects are obvious.

Description

technical field [0001] The invention relates to a planting method of yew and the application of 5-aminolevulinic acid. Background technique [0002] Yew is a precious species left over from Quaternary glaciers. It is a precious tree species under national first-class protection. It is a tree species with high economic value that integrates medicinal, ornamental, greening, and special high-quality materials. Plants of the genus Taxus are plant resources for extracting the anticancer drug Taxol. The genus Taxus is an evergreen tree distributed in the northern hemisphere. There are about ten species and several varieties in the world. The Chinese Taxus (Taxus Chinensis), the Northeast Taxus (Taxus Cuspidata), and the Yunnan Taxus are mainly distributed in my country. (Taxus Yunnanensis), Tibetan yew (Taxus Wallichiana); European berry yew (Taxus Baccata), mainly in Europe; short-leaved yew (Taxus Brevifolia) and Canadian yew (Taxus Canadensis), mainly in North America , Taxus F...
