摘　　要：在自然条件下，乌天麻和红天麻花期相差20～30d，在相同条件下试验栽培，乌天麻和红天麻花期相差7～8d，通过利用薄膜小棚和海拔高差，调控乌天麻与红天麻发育过程，促其花期相遇并获得成功，且调控成本比室内加温低，实用性强，为乌天麻和红天麻杂交育种开辟了一条新途径。Under natural conditions, the florescence differences of Gastrodia elata BI. f glauca S Chow and G. elata. BI. f elata are twenty to thirty days, but given the same conditions, they can be shortened to seven or eight days by experimental cultivation. In order to cultivate the sexual crossbreeding of Gastrodia elata BL f glauca S Chow × G. elata. BI. f elata, vinyl house and differentiation of altitude are used to get flower synchronization by controlling their development, which makes a new way for crossfertilization of Gastrodia elata BI. f glauca S Chow and G. elata. BI. f elata.
