地处湘西的怀化地区自然条件优越,是野生兰花资源的基因库。该地区属中亚热带湿润季风区的林区,年均温度16.3—17.1℃;年日照≥10℃;积温在5064.4—5453.3℃之间;日照≥10℃的植物生长持续期为240天左右;日温≥15℃的植物旺盛期为182—191天,无霜期279—302天,降水量全年在1160.7—1456.7毫米间。山地年降水量最高达1799毫米以上,成土母岩共有七大类,其中变质板岩、沉积页岩占62％。这类母岩形成的土壤结构细,土壤矿物质养分高,保水、保肥力强,疏松肥厚,有利于兰花生长。
Huaihua is located in the western region of the natural conditions of superior, is a wild orchid gene pool of resources. The area is a subtropical humid monsoon region of forest, with an average annual temperature of 16.3-17.1 ℃; annual sunshine ≥ 10 ℃; accumulated temperature 5064.4-5453.3 ℃ between; sunshine ≥ 10 ℃ plant growth duration of 240 days; day Plant temperature ≥15 ℃ for the period of 182-191 days, frost-free period 279-302 days, the precipitation in the year between 1160.7-1456.7 mm. Annual rainfall of up to 1799 mm above the mountain, into a total of seven types of mother rock, metamorphic slate, sedimentary shale 62%. The formation of such mother rock structure of fine soil, soil mineral nutrients high, water, fertility and strong, loose and plump, is conducive to orchid growth.
