Dendrobium officinale generally grows in the deep mountain forests and the yin stone cliffs on the cliffs that are rarely visited. Dendrobium officinale reproduces through wind and insect propagation, and it takes 2-3 years to harvest from seed germination to commercial stage. Due to the special growth environment and the extreme difficulty of self-reproduction and the excessive excavation of people, the resources of wild Dendrobium officinale are decreasing day by day, and it is listed as a national second-class protected plant.

Dendrobium officinale has very strict requirements for the growth environment and climatic conditions, it grows at an altitude of 500-1000 meters, the relative humidity is 60-75%, the light transmittance between the forests is about 60%, the humidity in the growing season is 20-25 degrees, the winter temperature is 9-12 degrees, and it is frost-free and foggy, and the annual rainfall is 1100-1500 mm in the evergreen broad-leaved forest and limestone.

In view of the scarcity of Dendrobium officinale and the difficulty of artificial cultivation technology, and the actual situation that it has broad medicinal value, the agricultural development of Lianhua Town, Jiande City, under the technical guidance of scientific researchers from Zhejiang University, has built and managed 20 acres of Dendrobium officinale production base in accordance with the requirements of GAP through two years of exploration, and declared the scientific and technological development project of "large-area and high-density artificial cultivation of Dendrobium officinale" to Hangzhou.

The tissue culture seedling technology of Dendrobium officinale of Zhejiang University is first-class in China, and the tissue and composition of its tissue culture seedlings are exactly the same as those of wild Dendrobium officinalis. Under the technical guidance of researchers from Zhejiang University, the agricultural development of Lianhua Town, Jiande City, has carried out large-area and high-density artificial cultivation research and experiments on tissue culture seedlings, and has achieved success.

Large-area, high-density artificial cultivation of Dendrobium officinale is the only way to expand the application field of Dendrobium officinale and benefit mankind, and the natural environment of Jiande is very suitable for artificial cultivation of Dendrobium officinalis. Through the practice of lotus agricultural development, it has been proved that the seedlings of Dendrobium officinale are tissue culture and transplanted, as long as they are operated in strict accordance with the procedures, the survival rate is relatively high, reaching more than 95%.

Due to its rarity, the planting benefits of Dendrobium officinale are very considerable. According to the planting experience of Lianhua Town Agricultural Development Company, the investment per mu is about 70,000 yuan, and the output value per mu can reach 200,000 yuan. In the international market, dried Dendrobium officinale products in Southeast Asia reach more than 8,000 Hong Kong dollars per 500 grams, and the supply is still in short supply.

Therefore, the cultivation of Dendrobium officinale has broad market prospects.
