The data shows that in 2015, the total value of the traditional Chinese medicine industry in China reaches 7866 hundred million yuan, which accounts for nearly 1/3 of the scale of the medical industry, and traditional Chinese medicine industry, traditional Chinese medicine agriculture, traditional Chinese medicine business, traditional Chinese medicine health products, food, daily chemical products and the like are derived. The traditional Chinese medicine has huge breakthrough in the health industry and huge market development potential. With the better living materials of people, people are more healthy and scientific to drink, and the medicated food has great innovation space. With the progress of medical science and technology, the development of traditional Chinese medicine is accelerated, the health of human beings is benefited, and the traditional Chinese medicine further moves to the world. At present, a traditional Chinese medicine standard system is formed at first, the standard quantity reaches 649 items, the annual average growth rate of the traditional Chinese medicine development is about 29 percent, and the traditional Chinese medicine has the characteristics and the efficacy which cannot be replaced by western medicines. Particularly, with the gradual improvement of health consciousness of people, the Chinese herbal medicine health care product is the key point of the development of the field of the health care product. The national policy issued by the state in recent years inclines the development of Chinese herbal medicine towards the health care aspect of Chinese herbal medicine. Under the background of vigorous policy support and continuous popularization of traditional Chinese medicine health-preserving knowledge, enterprises and consumers have deepened understanding of traditional Chinese medicines, more and more people are willing to replace western medicines with traditional Chinese medicines, even in the normal health management process, the traditional Chinese medicines are also more popular with consumers, and the substitution effect of the traditional Chinese medicines on the western medicines is expanded.
Rhodiola rosea (Rhodiola) is a perennial herb or shrub plant of Rhodiola of Crassulaceae, is one of rare medicinal plants, and wild Rhodiola rosea grows under mountain slopes or on grass slopes in alpine and pollution-free areas with the altitude of 1800 m to 2500 m. The growth environment is severe, such as anoxia, low temperature drying, high wind, ultraviolet irradiation, and large day and night temperature difference, so that the biological organic fertilizer has strong vitality and special adaptability. Is a common traditional medicinal material in Asian regions, and has the effects of stimulating nervous system, increasing work efficiency, eliminating fatigue, preventing mountain sickness and the like. Over two hundred varieties of rhodiola have been identified, of which about twenty are common medicines in traditional medicine in asia, such as rhodiola crenulata, rhodiola rosea, rhodiola sacra, etc. Especially rhodiola rosea, has been studied extensively. Su Union scientists in the sixties of the twentieth century discovered that it had an adaptogenic effect and could help the body return to homeostasis. That is, rhodiola rosea can improve the body's resistance to various stimuli from chemical, biological or physical factors. In addition to the traditional anti-stress function, scientists have focused on new findings about rhodiola rosea, including anti-cancer and anti-diabetic.
The existing rhodiola rosea is excessively grazed and artificially mined without plans, so that the population quantity of the rhodiola rosea serving as one of the group species in the system is in a descending trend, and the distribution pattern is seriously damaged. On one hand, the maintenance and development of the rhodiola rosea population are limited, and on the other hand, the change of the quantity and the pattern of the rhodiola rosea population influences the survival condition of the companion species, so that the stability of the alpine meadow ecosystem is reduced. With the continuous and deep understanding of the new pharmacological action of rhodiola rosea, the demand will be expanded continuously. Efforts have been made to find a planting method that allows the artificial planting of rhodiola rosea of the same quality as wild rhodiola rosea. However, the rhodiola rosea has higher requirements on the environment and is difficult to grow in low-altitude areas, the existing artificial cultivation mainly improves the planting environment to cultivate the rhodiola rosea, but the survival rate, the yield and the quality are difficult to meet the requirements. Therefore, the seedling culture domestication becomes an effective method for batch cultivation of the rhodiola rosea in low-altitude areas.
