Introduction

Dendrobium devonianum, also known as the scented grass, rhubarb, is the Orchidaceae (Orchidaceae) Dendrobium (Den-Drobium) is an important forest medicinal plant resource in the low latitude tropical and subtropical regions of China, and is the weight of the traditional Chinese medicine Dendrobium One of the raw material plants, the research proves that its components such as Dendrobium polysaccharide, Dendrobium, amino acid and mineral elements are close to Dendrobium candidum. due to in recent years, disorderly mining, China's natural resources of Dendrobium candidum is in an endangered state. The cultivation method of Dendrobium candidum is mainly based on tissue culture.

Plugging and breeding seedlings are also used; their cultivation is currently based on facility cultivation and imitation of wild cultivation. There is no uniform cultivation and cultivation of Dendrobium nobile in China.

The technical standards, the quality of seedlings and stems are different, which seriously affects the production effect and industrial development of the current Dendrobium. Therefore, it should be standardized as soon as possible the cultivation technology of Dendrobium candidum meets the needs of medicinal Dendrobium production under current conditions, and provides technology for the development of Dendrobium candidum industry.
