摘要
[目的]研究不同遮阴条件对大花萱草生长的影响。[方法]对3种不同大花萱草的品系进行遮阴处理,在生长季内对其形态及生物量进行观测。[结果]在40%光照条件下,3种大花萱草在形态上表现良好,观赏性较高;低于40%的透光率不利于其物质积累,生物增量减少,但根部增量总体大于叶片。[结论]大花萱草更适宜在40%以上的光照条件下作观赏地被。
[Objective] The aim was to understand the influences of different shading conditions on the growth of Hemerocallis middendorffii.[Method] The morphology and biomass of Hemerocallis middendorffii were observed under different shading treatments in the growing season.[Result] Three kinds of Hemerocallis middendorffii had better performances in 40% light codition,and they had better enjoyment;It＇s not good to the accumulation of material,and the biological increment reduced when the light transmission rate was less than 40%,but the root increment was greater than the leaf.[Conclusion] Hemerocallis middendorffii were more suitable to be ornamental ground cover under more than 40% of the light conditions.
