Method for three-D cultivation of camptotheca acuminata, Chinese yew and rosemary

Abstract

A stereo-culture method for Camptotheca acuminata, enqlish yew and rosemary features that they are planted at different densities according to their biologic and ecological characteristics to increase their yields per unit area.

Description

Technical field: [0001] The invention belongs to the field of high-tech agricultural planting, and in particular relates to a three-dimensional cultivation method for camptophyllum, southern yew and rosemary. Background technique: [0002] Camptopheca acuminata Decaisne, a perennial deciduous broad-leaved tree belonging to the family Camptopheca acuminata, grows rapidly, and the tree can reach a height of 25-30 meters. Camptothecin, which has significant anticancer activity, is isolated from Camptopheca acuminata Decaisne. It has obvious curative effect for treating gastric cancer, tracheal cancer, colon cancer, rectal cancer and other malignant tumors. Southern yew (Taxus Walichiana Var.mairei) belongs to Taxaceae, Taxus genus, and the southern yew young forest stage is a negative tree species. 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 cance...

Problems solved by technology

Although this method can utilize different nutrient spaces to a certain extent, there is a certain competition between the two plants, and the added value is small, and the output benefit is low.

[0006] 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 literature 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. It is only a pure forest of Taxus chinensis, and does not involve the cultivation method of Taxus chinensis mixed with other plants, and the afforestation of Taxus chinensis in these literature reports requires the construction of shade sheds, the incidence of diseases and insect pests is high, management is difficult, and production high cost

[0007] To sum up, the artificial planting of the three plants has problems such as low land utilization rate, low output benefit, and high production cost. The three are not organically combined and rationally allocated.
