石斛(Dendrobirm nobile Lindl)属兰科多年生草本植物,为常用中药,《神农本草经》列为上品,是效果十分显著的强阴益津药。据《本草纲目》载:“石斛丛生石上。处处有之,以蜀中者为胜”。据重庆大宗药材出口统计表,1932年——1934年重庆平均年出口鲜石斛62313斤,黄草(干石斛)7505斤,说明石斛曾是四川历史上产量很大的药材。但近年来石斛的引种、栽培、繁殖进展较慢,产量下降,产销矛盾十分突出。我们于1986年开始用无土栽培法对石斛的栽培方法和环境生理作了多种研究试验,
Dendrobirm nobile Lindl is a perennial herb of Orchidaceae. It is a commonly used traditional Chinese medicine, and Shennong Bencaojing is listed as a top grade product. It is a powerful Yin-Yijin medicine with remarkable effects. According to the “Compendium of Materia Medica,” it reads: “Stone cymbals are clustered on rocks. There are everywhere, and those who live in the mountains are the winners.” According to statistics on exports of major medicinal herbs from Chongqing, from 1932 to 1934, Chongqing exported 62,313 kilos of fresh sarcophagus and 7,055 jin of huangcao (dry sarcophagus) on average. This shows that Shiqi used to be a large amount of medicinal material in Sichuan history. However, in recent years, the introduction, cultivation, and propagation of Dendrobium nobilis have been slow, yields have declined, and the contradiction between production and marketing has become prominent. In 1986, we began to conduct a variety of research and experiments on the cultivation methods and environmental physiology of Dendrobium using soilless cultivation methods.
