Wild or imitation of wild environment, 230 to 800 meters above sea level, pH 6.5 to 7.2, organic matter content 1% to 2%. (3) Cultivation techniques. 1. Seed collection and seedling selection: In the end of November each year, mature Dendrobium candidum is collected at the place of production, and tissue culture seedlings are used to produce tissue culture seedlings. Seedlings for production are selected to be free of pests and diseases, and robust wild seedlings or tissue culture seedlings. 2.
