摘　　要：施用氮肥是天彭牡丹栽培过程中养分调节的重要环节。以红丹兰和丹景红为供试材料,研究外源施氮CK(对照,不施尿素)、N1(施尿素1.4 g/盆)、N2(施尿素2.8 g/盆)对其生长形态的影响。结果表明,红丹兰和丹景红植物株高、冠幅、叶柄和顶小叶面积均显著增加,表现为N2>N1>CK。除营养生长外,适当增加氮肥(N1)可以显著提高天彭牡丹花朵大小,延长花期,增加牡丹的观赏价值。Application of nitrogen fertilizer is mainly of Tianpeng tree peony cultivation process. In this case, the experiment used ＇Hongdanglan＇and ＇Dangjinghong＇ which were special species in Tianpeng tree peony communities as tested materials. The aim was studying influence of exogenous nitrogen CK （control, no urea applying）, N1 （urea 1.4 g/basin）, N2 （ urea 2.8 g/basin） to morphology growth of Tianpeng tree peony and provide experimental basis for its fertilization management. The results indicated that the influences of external nitrogen on the growth and morphological were mainly concentrated in the plant height, crown width, leaf area. It showed that significant increasing trend was to be N2〉N1〉CK. In addition to the vegetative growth, external nitrogen could remarkably improve the Tianpeng tree peony flower size, extend flowering period and increase the Peony Ornamental value in ＇Hongdanglan＇and ＇ Dangjinghong ＇.
