Tripterygium wilfordii hook acclimatization and high-yielding method

Abstract

The invention provides a tripterygium wilfordii hook acclimatization and high-yielding method. A cut section of the stem of the tripterygium wilfordii hook is adopted for culturing and breeding, and abundant materials provide a foundation for breeding and acclimatization of mass wild tripterygium wilfordii hook. The method comprises the following steps: preparing a nursery garden; raising seedlings by cutting; transplanting; and managing a base. The method is a complement for wild tripterygium wilfordii hook resources, and has great significance in developing subsequent industry of tripterygium wilfordii hook exploitation.

Description

【Technical field】 [0001] The invention relates to a method for cultivating medicinal plants, in particular to a method for domesticating tripterygium wilfordii and increasing its yield. 【Background technique】 [0002] Tripterygium Wilfordii (Tripterygium Wilfordii Hook f. TWHF for short) is a woody vine of the genus Tripterygium in the family Euonymus. Tripterygium wilfordii is highly poisonous, but it also has the functions of relieving blood coagulation, reducing blood viscosity, improving microcirculation and reducing peripheral blood resistance, as well as anti-inflammatory, anti-tumor, anti-fertility and other activities. Its chemical composition Mainly diterpenes, triterpenes, sesquiterpenes, alkaloids, etc. Therefore, Tripterygium wilfordii has important medicinal value. [0003] At present, Tripterygium wilfordii is mostly wild, mostly distributed in subtropical regions, such as the provinces from the south of the Yangtze River Basin to the southwest of China: such...

AI Technical Summary

Problems solved by technology

However, due to the long-term disorderly excavation of wild Tripterygium wilfordii and the impact of large-scale construction of artificial timber forests, the suitable environment for Tripterygium wilfordii has been destroyed, and its reserves and growth have declined sharply.

At present, the amount that can be excavated is extremely scarce. For example, the annual purchase amount in Taining County, Fujian Province is only 1-2 tons, which is far from meeting the demand

[0004] The wild triptolide grows slowly, and the content of medicinal ingredients is low (the content of triptolide and B is only 1 / 100,000), and the exploitable resources are gradually decreasing. Therefore, people began to gradually explore artificial planting methods, but Tripterygium wilfordii has few flowers and fruits, and the seeds have membranous wings. After maturity, they are easily blown away by the wind, are difficult to collect, and the germination rate is not high. This current cutting seedling raising method is limited to root cutting seedling raising, as the public number is CN1994044A, and the planting method of a kind of Tripterygium wilfordii disclosed in the Chinese patent application whose publication date is 2007.07.

But because it is root cutting seedling cultivation, its material selection is limited to the root system of Tripterygium wilfordii, and the root system of a strain of Tripterygium wilfordii is very limited, thus greatly limiting its large-scale propagation
