一、翻栽 天麻种子发育成天麻球茎，翻挖出来的米麻和白麻称一代种。一代种经扩大栽培后翻挖出来的种麻称二代种，二代种翻挖时已有箭麻形成。通过一、二代种麻的翻种，找出有优势，产量高的杂交组合种进行繁殖。杂交二代种形成的箭麻，既可作商品麻，又是进行杂交育种的种麻。另有不断的杂交繁殖才能筛选出高产优质的栽培品种。第三代天麻翻挖、所收天麻中的米麻、白麻与箭麻约各占一半。白麻和米麻作最后一次栽培。否则将因麻种退化、造成“越种越小，越种越少”的现象。 一 收获

First, transplanting Gastrodia tuberosum seed developed into corms bulbs, dug out of the linen and white linen that a generation. A generation of seedlings after digging out by expanding the cultivation said that the second generation of the second generation of digging argan already formed. Through the first and second generation of hemp seed, find out the advantages of high yield of hybrid combinations for breeding. The second generation of hybrid arrowhead hemp, both for commercial hemp, but also for breeding of hybrid seed. Another continuous breeding to screen out high yield and quality of cultivars. The third generation of Tianma digging, the day received Ma in the linen, white linen and arrow Ma around about half. White hemp and rice for the last cultivation. Otherwise, due to the deterioration of hemp species, resulting in “the more species the smaller, the less the species” phenomenon. A harvest
