Abstract:
To explore the suitable habitat for wild simulated cultivation of Gastrodia elata in Yunna-Guizhou Plateau.Taking Gastrodia elata as test materials,the growth and development of Gastrodia elata were studied by field experiment.The results showed that the maximum output of 1 800 m was 912 g and 659 g respectively in different altitudes.The maximum output of 30°-50° steep slope was 588 g and 481 g respectively in different gradient.In the study of different slope directions，the south slope was the largest，1 266 g and 947 g respectively.In the study of different vegetation，the largest was arbor forest，which was 624 g and 397 g respectively.In the study of different canopy degrees，40% canopy degrees were the largest，815 g and 540 g respectively，followed by 30% canopy degrees，634 g and 494 g respectively.The simulated wild cultivation of Gastrodia elata could be carried out at an altitude of 1 200-1 800 m，a gradient of 0°-50°，any slope directions，arbor or shrub forests or mixed forest of arbor and shrub，and a canopy degrees of 30%-70%.But the environment with the altitude of 1 800 m，slope of 0°-30°，slope direction as the south slope，arbor forest，30%-40% canopy density was the most suitable environment.
