Artificial cultivation method for taxus chinenesis containing high content taxol

Abstract

The present invention relates to an artificial cultivation method of southern Taxus chinensis with high taxol content, belonging to the agricultural planting field using high and new technology. It is characterized by that according to the characteristics of southern Taxus chinensis which has stronger adaplation for weather, humidity resistance and whose seedlings and young forest growth have need of shade environment said invention can artificially construct a stereoscopic composite community for providing a shade environment for southern Taxus chinensis growth.

Description

Technical field: [0001] The invention belongs to the field of high-tech agricultural planting, and particularly relates to a method for artificially cultivating southern yew with high paclitaxel content. Background technique: [0002] Southern yew (Taxus Walichiana var.mairei) belongs to the family Taxaceae and belongs to the genus Taxus. Southern yew has a strong ability to adapt to climate and is resistant to dampness. It needs a negative environment in the young forest stage to grow normally. Paclitaxel, a component with significant anti-cancer activity isolated from the southern yew, is used to treat breast cancer, ovarian cancer, non-small cell lung cancer, colon cancer and other cancers, with definite curative effect and less side effects. Therefore, the artificial cultivation of the southern yew has significant economic and social benefits. [0003] Because the southern yew belongs to the national first-class wild protected plants, the resources are scarce, and the h...

Problems solved by technology

This method only pays attention to the paclitaxel content, and does not consider the surrounding environment and paclitaxel quality problems after the application of rare earth elements. This method uses chemical methods to increase the paclitaxel content, not the application of biotechnology. The paclitaxel content is increased through artificial regulation.

[0007] The patent with the publication number CN200510011455.4 introduces a method for increasing the paclitaxel content in Taxus chinensis, which is to spray crowns on the stems and leaves of Taxus saplings. Taxol yield, but this method also uses chemical means to increase the paclitaxel content, not through environmental influences to increase the paclitaxel content, and does not introduce the different planting measures, especially the planting measures to increase the paclitaxel content of the southern taxus

[0008] Publication No. CN200410043959.X patent introduces a planting method of yew. The method introduces the process of seed collection, selection of nursery land, fertilization, seed germination, field management and overwintering protection, and introduces the cutting seedling raising method. The method solves the problem of the artificial planting method of yew, which also belongs to the problem of yew resource cultivation, and does not involve the scope of increasing the content of paclitaxel, especially does not involve the problem of increasing the content of paclitaxel by artificially adjusting the planting method

[0009] The patent with the publication number CN03112973.0 introduces a method of artificial cultivation of yew. This method focuses on matters such as fertilizer, water content and transplanting in the soil during yew planting. The advantage of this method is that it can cultivate yew in large quantities. , to solve the problem of endangered resources, but yew is a rare and endangered plant with great medicinal value. Its main utilization value lies in the special anticancer active substance paclitaxel contained in the body. This method does not solve the problem of increasing the production of paclitaxel

[0010] Due to its extremely scarce resources and high medicinal value, the southern yew has many related scientific research reports, mainly focusing on the study of the southern yew population structure, breeding technology, physiological and ecological characteristics, reproduction, and paclitaxel extraction technology. The research on the cultivation of Taxus chinensis is limited to the research on the silviculture technology of Taxus chinensis published in Forestry Science and Technology in September 1999, and the research on the cultivation and growth of Taxus chinensis plantations published in the Newsletter of Science and Technology in Forestry in June 2001. In April 2002, there were a few reports on the method of growing seedlings of Taxus chinensis under forests published in Forestry Practical Technology. The common feature of these documents is that they mainly introduced measures such as seed collection, germination, sowing, nursery management, and planting of Taxus chinensis. To improve the cultivation method of paclitaxel increment, and these literatures report that the incidence of diseases and insect pests of Taxus chinensis is frequent, management is difficult, and the production cost is relatively high.
