天麻(Gatrodia elata B1.)属兰科,为多年生草本,以块茎入药。它无根无叶,与蜜环菌共生,依靠其供应营养。因此,在人工栽培中,要创造既适合蜜环菌生长,又适合天麻生长的环境条件。这是成败的关键。栽培天麻必须符合以下要求: 一、温度要求(这是最主要的):蜜环菌一般在6—8℃开始生长,20—25℃生长旺盛,30℃即停止生长。天麻于15℃时开始生长,25℃时生长最旺,超过30℃或低于10℃时停止生长;适温期越长,生长越快,形成块茎越大。因此,天麻适宜在温暖湿润地区
Gastrodia (Gatrodia elata B1.) Is an Orchidaceae, perennial herb, Tuber medicine. It has no root no leaf, symbiosis with Armillaria, rely on its supply of nutrition. Therefore, in artificial cultivation, to create both suitable for the growth of Armillaria, but also for the growth of Gastrodia environmental conditions. This is the key to success. Gastrodia must meet the following requirements: First, the temperature requirements (which is the most important): Armillalla generally 6-8 ℃ began to grow, 20-25 ℃ vigorous growth, 30 ℃ to stop growing. Gastrodia start to grow at 15 ℃, 25 ℃ when the growth of the most prosperous, more than 30 ℃ or less than 10 ℃ to stop growing; the longer the suitable temperature, the faster the growth, the greater the formation of tubers. Therefore, Tianma suitable for warm and humid areas
