9种崂山野生观赏花卉引种筛选研究

目的]围绕野生花卉的园林观赏性以及繁殖难易程度两个方面，进行9种崂山野生观赏花卉的引种繁殖试验与生长发育特性研究。方法]9种野生观赏花卉分别为山东万寿竹（DisporumsmilacinumA．Gray）、长药八宝Hylotelephiumspectabile（Bor．）H．Ohba]、费菜（SedumaizoonL．）、红蓼（PolygonumorientaleL．）、鹤草（SilenefortuneiVis．）、瞿麦（DianthussuperbusL．）、黄堇Corydalispallida（Thunb．）Pers]、白英（SolanumlyratumThunb．）、栝楼（TrichosantheskirilowiiMaxim．）。结果]引种花卉在栽植环境中生长发育良好，能够表现出各自的优良观赏性状，全年绿期在240d以上，花、果的最佳观赏期长于30d，繁殖成活率均高于80％，除山东万寿竹受种源稀缺限制外，其他花卉均能够在短期内大量生产。最后，结合城市景观营造和每种花卉的观赏特性，对这些野生花卉的生产利用提出了建议。结论]9种花卉除了可以作为育种资源，也可以直接应用到城市绿地中作为景观要素，丰富城市绿地的物种指数，对其开发利用具有重要的指导意义。

Study on Introduction and Cultivation of 9 Wild Flowers in Mountain Lao

Objective ] Accor-ding to the ornamental characteristics and the reproductive capacity, the propagation, growth and development of 9 wild flowers were studied through introduction tests. Method] The 9 wild flowers were Disporum smilacinum A. Gray, ttylotelephium spect- abile （Bor.） H. Ohba, Sedum aizoon L. , Polygonum orientale L. , Silene fortunei Vis., Dianthus superbus L. , Corydalis pallida （Thunb.） Pers, Solanum lyratum Thunb. , Trichosanthes kirilowii Maxim. , resp.. Result] The results indicated the 9 wild flowers grew well in experi- mental environment. They showed several excellent ornamental characteristics, such as more than 240-day-lasting green leaves, more than 30- day-lasting flowers and fruit, and over 80%-survival rate. They were easy to reproduce except Disporum smilacinum A. Gray, because it was less population. Some suggestions were summed up on the exploitation and utilization of the wild flowers. Conclusion] The nine wild flowers are not only as breeding resources, but also using directly in urban green space as landscape elements to enrich its species index, so it has an important guiding significance to develop and use them.
