以乡土树种兴安杜鹃作为对照,对迎红杜鹃物候及生长节律进行了试验研究,结果表明：有效积温达到324~631℃时这2种杜鹃正值开花时节,兴安杜鹃的花期要比迎红杜鹃长1周；当有效积温达到529℃时这2种杜鹃开始进入营养生长阶段。不同光照条件对迎红杜鹃和兴安杜鹃生长量影响显著,2种杜鹃在3种不同光照条件下均以半光照的年高生长量最大,迎红杜鹃为20.34 cm,兴安杜鹃为15.38 cm。

Taking Rhododendrondauricum (the native tree species)as CK,phenology and growth rhythm of Rho-dodendronmucronulatum were studied.Result shows that when the effective accumulated temperature reached 324-631 ℃,two Rhododendron are in process of blooming.Florescence of Rhododendrondauricum is one week longer than that of Rhododendron mucronulatum.When the effective temperature reached 5 2 9 ℃,both of Rhododendron began to enter the vegetative growth stage.Different lighting conditions affect significantly the growth of Rhododen-dron mucronulatum and Rhododendrondauricum.The annual height growths with half-light condition of both Rho-dodendronsimsii are the largest under three light conditions:Rhododendronmucronulatum is 20.34 cm;Rhododen-drondauricum is 15.38 cm.
