摘　　要：[目的]丰富园林绿化中黄色系的芍药属植物种类,也为牡丹(Paeonia suffuruticosa)远缘杂交新品种的推广奠定基础。[方法]通过对牡丹新品种‘金波’物候期的观测,研究其与气温、空气湿度和地温的关系,掌握其生长规律。[结果]‘金波’从3月4日开始萌动,萌动期12 d;4月10日进入风铃期,持续10 d;4月28日进入开花期,花期持续22 d,此期间平均气温14.8℃,地温14.8℃,相对湿度78.6%。新品种‘金波’开花晚于中原栽培品种,且花期长于中原栽培品种。[结论]对‘金波’加以推广利用,有利于延长牡丹栽培品种的观赏期,丰富牡丹观赏品种的类型。[ Objective] The aim was to enrich the yellow Paeonia plant species during landscaping, and lay basis for promotion of new distant hybridization P. suffuruticosa variety. [ Method] The phenological phase of new cultivar P. suffuruticosa ＇ Jin Bo＇ was observed, and then stud- ied their relationship between phenological phase with air temperature, air humidity and ground temperature to graspe its growth law. [ Result ] Sprouting time of Jinbo＇started from March 4, for a period of 12 days; the period before blooming started from March 10, lasting for 10 days; the flowering time started from April 28, lasting for 22 days, at this period, the average temperature was 14.8 ℃, the average soil temperature was 14.8 ℃ and the air humidity was 78.6%. The flowering date of the new variety P： suffaruticosa ＇ Jin Bo＇ was later than that of the late flowering cuhivars from the Central Plains, and its flowering period was longer than that of the Central Plains cultivars. [ Conclusion] That promotion and use P. suffuruticosa ＇Jin Bo＇ prolongs the viewing period and enriches the ornamental P. suffuruticosa cultivars.
