利用立体气候快速繁育杂交天麻

Rapid Cross Breeding of Gastrodia at Tridimensional Climate Conditions

通过试验和回归分析，研究在利用立体气候条件下杂交天麻种子繁育、发芽、生长的最适地段气温与地温的关系，从而确定利用立体海拔气候分“三段”（即品种园、有性杂交试验区、良种场）建天麻杂交良种基地和快速繁育杂交天麻的有效途径。

Optimum tridimensional climate conditions for the rapid cross breeding of Gastrodia was sought through experiments and regression analysis. Relationship between the location for sprouting and growth,temperature range and ground temperature was studied to establish the best approach for the rapid cross breeding which consisted of 'three stages'(variety plot,sexual hybridization region and elite species nursery)in the utilizationof tridimensional climate condition at elevations above sea level.
