摘要 [目的]筛选适宜在山东滨州市种植的玉簪新品种。[方法]以引自北京、上海的13個玉簪新品种为试材，观察记录其在滨州的物候期、适应性，并对其观赏特性进行分析。[结果]引进的13个玉簪品种在滨州的生长表现不一，物候期差异较大。“冰与火”“巨无霸”“爱国者”“首霜”“神枪手”等9个品种，适应性较好，观赏性状优良，适合在滨州进行栽培和园林应用；“大父”“威严”等4个品种，在滨州地区整体表现不良，不适合进行大规模园林应用。[结论]该研究可为玉簪品种在滨州市的推广应用提供依据。

Abstract [Objective]To select Hosta new species suitable to be planted in Binzhou，Shandong. [Method]The phenological observation， adaptability and landscape characteristics of 13 hosta species introduced from Beijing and Shanghai were studied in this paper. [Result]13 Hosta species had different phenological periods in Binzhou area. 9 Hosta species such as H. plantaginea “Fire and Ice”“Sum and Substance”“Patriot”“First Frost”“Sharp Shiiter” had better adaptability and higher ornamental value， perfectly suitable to garden application in large scale. 4 Hosta species such as H. plantaginea“Big Daddy”“Krossa Regal”performanced bad and had lower application value， the application of those was ineffective and did not good enough for garden application in Binzhou area. [Conclusion]The study can provide a basis for the promotion and application of Hosta species in Binzhou City.

玉簪是原产于我国的优良地被植物，具有花叶共赏、适应性强、栽培和养护成本较低、易于繁殖等诸多优点，特别适宜在光线较弱、光照时间较少的林荫种植[1]。玉簪具有较高的观赏价值，在欧美地区园林中已应用多年[2]，是世界上销量最大的草本花卉[3]。我国栽培的玉簪种类非常单一，仅局限于少数玉簪品种[4]。随着城市化进程的不断加快，园艺工作者加快了玉簪引进的步伐，中国林业科学院较早地进行了优良玉簪新品种的引进工作[5]，中国科学院植物研究所、沈阳植物园等也都先后进行了玉簪新优品种的选育与评价工作，育成了不少优良新品种[6]。

目前，山东省仅烟台地区初步进行了新优玉簪品种引种栽培工作，尚未见到新优品种大规模园林应用的报道[7]。为丰富滨州城区的宿根花卉种类，创造出更好的园林绿化效果，滨城区园林绿化工程管理处从国内外系统引进玉簪新优品种，其中从上海引进8个玉簪新品种，进行物候期观测及栽培试验研究，以期为玉簪品种在滨州市的推广应用提供依据。……
