摘要：

为了筛选出适宜屋顶绿化需要的节水抗旱木本植物，在2010年4—6月，以石家庄市的气候条件为基础，测定自然干旱胁迫条件下16种屋顶绿化木本植物的叶片面积、相对含水量、质膜相对透性、可溶性糖含量等指标，综合分析16种木本植物树种的抗旱性。结果表明，柳树、小叶杨、白榆、杠柳抗旱性最强，推荐用于屋顶绿化；金叶女贞、桑树、紫叶小檗、棣棠、红瑞木、珍珠梅、金银木、臭椿、大叶黄杨的抗旱性中等，通过精细管理也可用于屋顶绿化；金叶榆、构树、火炬的抗旱性弱，建议选用时应加强灌溉措施。

Abstract:

In order to select suitable water- saving and drought-resistant woody plant for roof greening, Based on the Shijiazhuang climatic conditions, the leaf area, relative water content, relative permeability of the plasma membrane and soluble sugar content of 16 species of roof greening woody plants were determined, and the drought resistance of 16 species woody plants were analyzed comprehensively in April to June 2010. The results showed that Salix matsudana, Populus simonii, Ulmus pumila, Periploca sepium had best drought resistance, and which were recommended for roof greening. Ligustrum ‘Vicaryi’, Morus alba, Berberis thunbergii ‘Atropurpurea’, Kerria japonica, Swida alba, Sorbaria kirilowii, Lonicera maackii, Ailanthus altissima and Buxus megistophylla had normal drought resistance, and which can be used for roof greening with fine management. Ulmus pumila ‘Jinye’, Broussonetia papyrifera, Rhus typhina had worst drought resistance, and can be used with better irrigation.
