| 摘 要： | 为更准确地掌握宿根花卉的观赏期,在北京园林中更好地应用宿根花卉,对北京常见的35种宿根花卉进行为期3 a的观赏期观测,将传统以月为基本单位的花期精确至以旬为基本单位,并记录宿根花卉的花前、花期、花后的景观特点用于指导应用实践。同时,为使宿根花卉的花期景观更为持久,对其中的13种宿根花卉进行了延长花期试验。结果表明:大花金鸡菊、宿根天人菊、千屈菜等10种宿根花卉可二次开花。

| Abstract: | In order to master display time of perennials more accurately and use perennials better,the three-year observation of 35 common perennials was made.The article changed traditional basic unit from month to ten days of flowering period,observed and recorded the view of perennials before flowering,flowering and after flowering for guiding practice.In order to prolong the view of perennials,13 perennials flowering period was purposed to prolong,the result showed the 10 of the tested perennials could flower twice. |
