摘要
城市屋顶绿化是城市生态环境建设的重要内容,日益受到重视,也亟需营建和养护技术。在分析西安市屋顶绿化成功案例和失败现状,夏季高温、阳光辐射强、水分蒸发快,冬季寒冷干燥少雨等植物生长严苛环境条件基础上,提出了西安市屋顶绿化植物养护技术,包括减少并控制灌水量和灌水次数、注重春季萌芽水和初冬防寒水等灌水排水技术,在培优植物生长基质基础上少施肥,选用污染小、营养成分含量高缓释性复合肥等施肥技术,灌木冬季休眠期修剪、乔木及时修剪枯死枝、病虫枝、徒长枝、交叉枝等以及地被植物修剪技术,尽可能不防治和不采取化学防治,首选农业、人工、物理方法等病虫害防治技术,树干包裹或涂刷石硫合剂、宿根花卉覆土、浇灌防冻水、培育壮苗等防寒技术,搭建防晒网、修剪树冠通风等防晒技术,检查肥力、局部补充有机基质并松土等基质维护技术。
Rooftop greening is located in a special ecological space position,hot,sunny,strong evaporation in summer and cold,dry in winter.Rooftop green has experienced success or failure in Xi'an.Based on the past experience and special ecological habitat learned,rooftop greening technologies and management were developed,regarding irrigation and drainage in summer,spring and winter;fertilization in relation to the substrate applied;pruning to remove dead limbs,disease limbs and overgrown twigs;disease and insects control by chemical,agricultural and manual approach in order to reduce the use of pesticides;and maintenance measures like shading,freezing proof and soil improvement.
