宿根花卉在节水园林中的调查应用

Survey on Applications of Perennial Flowers in Water-saving Gardens

北京属于资源型重度缺水地区,是111个特贫水城市之一,因此发展节水型园林是城市化进程的必然趋势。耐旱植物的筛选和应用则是其中一个重要技术手段。宿根花卉是指冬季植株地上部分枯萎,地下部分宿存于土壤中越冬,翌年春季再萌发生长、开花结籽的多年生花卉。宿根花卉是一类非常重要的露地观赏植物,在城市园林绿化中越来越受到重视,宿根花卉品种多,花色、花期及株型非常丰富,与其他类型的园林植物搭配种植,能极大地丰富园林景观。尤其是在现在水资源极度缺乏,而很多的宿根花卉管理简便,耐旱省水,非常符合节水型园林的要求。本研究在提香草堂的园林绿化项目中,重视宿根花卉的使用,结合宿根花卉的调查应用,大量使用了宿根花卉,丰富了项目的园林景观,也适应了节水园林的应用号召。

Beijing is the resource - severe dryland, one of 111 special water - poor cities in the world, so the development of water - saving garden is the inevitable trend of urbanization. Selection of drought - tolerant plants and is one of the important techni- cal means. The perennial flowers mean that aboveground part of plant wither in winter, the underground parts go through wintering germination in soil and grow, flower and seed in the following spring. Perennial flowers are very important ornamental plants exposed to more and more attention in the urban landscape, with many varieties, flower colors, florescences and plant types. If perennial flow- ers are planted with other types of garden plants, the garden landscape will be greatly enriched. Especially in the cities ofextreme shortage of water resources, many perennial flowers are easy to manage, drought - resistant and water - saving, greatly in line with the requirements of water - saving gardens. This paper takes landscaping project Tiziano garden as an example, emphasizes on the use of perennial flowers, combines with survey and applications, enriches the landscape of this project, and adapts to the application of water - saving garden.
