天麻在我国入药已有两千多年的历史 ,但由于它无叶无根 ,不能进行光合作用 ,国内外多年研究都未能人工栽培成功。 6 0年代初 ,中国医学科学院徐锦堂教授等科研人员分离培养出与天麻共生的蜜环菌 ,使人工栽培获得成功。 70年代 ,徐锦堂教授等又研究出天麻无性繁殖固定菌床栽培新 Gastrodia elata has been used for more than 2,000 years in our country. However, because it has no leaves and roots, it cannot be used for photosynthesis. Many years of research at home and abroad have failed to be cultivated successfully. At the beginning of the 1960s, Professor Xu Jintang of the Chinese Academy of Medical Sciences and other researchers isolated and cultured Armillariella communis that was symbiotic with Gastrodia and made artificial cultivation successful. In the 1970s, Prof. Xu Jintang and others also studied the cultivation of fixed strains of aflatoxin
