摘要 【研究目的】研制利用海拔温差调控种植天麻的技术方案,以求天麻种植科学便捷、经济有效。【方法】根据天麻生长发育的温度理论原理,观测并推算不同海拔高度气温与地温的对应值,确定如何利用海拔温差科学调控种植天麻。【结果】在湖北宜昌海拔1000m以上建立品种园,100m左右建杂交区,500m左右建良种场,800m以上建商品麻GAP基地最为经济有效:将有性种麻培育期节省了12个月,将有性乌天麻商品麻的生产周期节省了12个月,且保持优质高产;调控乌天麻与红天麻花期相遇,培育出鄂天麻1号、2号两个优良杂交新品种。【结论】利用海拔温差调控种植天麻的技术方案科学便捷、经济有效。 [OBJECTIVE]Through regultating temperature difference of altitude, Gastrodiae can be cultivated in a feasibIe and economical way. [METHODS]According to the Temperature Theory of the cultivation of Gastrodiae, researches on regulating the temperature difference of altitude were conducted, by observing and calculating the corresponding ground temperature of air temperature at different altitude levels. [RESULTS] The most effective way of Gastrodiae cultivation in Yichang is to set up breeding plantation at the altitude of 1000m, hybriding area at 100m, seed multiplication farm at 500m and GAP base for commercial gastrodiea at above 800m. In this way, the cultivating period of sexual seed tubers was shortened by 12 months and 12 months was saved for the cultivation for commercial tubers both with good quality and high yield. Besides, two novel hybrid species- Er No 1 and No 2 Gastrodiae were obtained by conforming the florescence of G. elata B1. f. elata and G. elata B1. f. glauca S. Chow. [CONCLUSION] Regulating the temperature difference of altitude is an efficacious and economical way of cultivating Rhizoma Gastrodiae.
