西安地区及周边观赏草应用调查

对西安市周边11个样点应用的观赏草种类及应用方式进行了调查分析。结果表明,西安市应用的观赏草共计39种(品种),分别属于禾本科、莎草科、天南星科、灯心草科、香蒲科、木贼科,应用最多的属是禾本科的芒属(Miscanthus Anderss.)和狼尾草属(Pennisetum Rich.),应用频度最多的种是细叶芒(Miscanthus sinensis Anderss.cv.Gracillimus),种类最丰富的样点是西安市雁塔南路和西安世界园艺博览园。观赏草的应用方式主要有孤植、丛植、片植、地被,搭配方式有水体搭配、岩石搭配、乔灌木搭配、宿根搭配等,应用类型最多的是片植。综合分析表明,很多观赏草已在西安市得到应用,但不均衡,今后需要丰富观赏草种类,适当开发乡土资源。
