Abstract

A method for cultivating the plant rhubarb includes such steps as physically and chemically treating seeds for high germination rate, artificial breeding, and cultivating.

Description

technical field [0001] The invention relates to a technique for introducing and cultivating plateau wild plants, in particular to a technique for introducing and cultivating two rare plateau wild plants, rhubarb tangut and rhubarb palmatum. Background technique [0002] The Qinghai-Tibet Plateau is a unique natural geographical unit in my country. Its unique natural environmental conditions breed rich and unique Chinese and Tibetan medicinal resources. Plateau plants have long adapted to the special natural environmental conditions in the plateau area, forming unique physiological-ecological characteristics. , has unique medicinal properties and efficacy. With the development of my country's medical industry and the expansion of the production scale of Chinese and Tibetan medicines, the demand for Chinese and Tibetan medicine resources has increased significantly. Due to the long-term excessive mining and the lack of effective protection of these resources, these plant resour...
