| 摘要: |
| 将曲柄藓(Campylopus flexuosus)、大灰藓(Hypnum plumaeforme)、东亚砂藓(Racomitrium japonicum)、大羽藓(Thuidium cymbifolium)、毛尖紫萼藓(Grimmia pilifera)和曲尾藓(Dicranum scoparium)这6种观赏藓类植物栽植于表面有薄层泥炭土—蛭石的棕榈垫这一立体绿化载体上.经过2个月的生长,测定了6种藓类植物的最大量子产量,计测了它们新枝覆盖率、新枝和旧枝长度比、叶绿素含量、单位面积鲜重等生长指标,比较了6种藓类植物在立体绿化载体上的综合适生指数.结果表明:适生指数由高到低分别为大灰藓、东亚砂藓、大羽藓、曲柄藓、曲尾藓和毛尖紫萼藓,结合景观效果观察,推荐大灰藓和东亚砂藓作为墙体绿化的藓类植物. |

| Abstract: |
| Six ornamental mosses (Campylopus flexuosus,Hypnum plumaeforme,Racomitrium japonicum,Thuidium cymbifolium,Grimmia pilifera and Dicranum scoparium) were transplanted onto vertical planting carrier(a palm pad with a thin layer of peat and vermiculite).After a two-month cultivation,their new branch coverage,newly-developed branches and their ratio with old branches,branches,fresh weight,chlorophyll content,and maximal photochemical efficiency were measured.Based on these indices,an integrated index revealing their growth capacity was calculated.Based on their integrated indices from high to low,six mosses were ranked as Hypnum plumaeforme,Racomitrium japonicum,Thuidium cymbifolium,Campylopus flexuosus,Dicranum scoparium,Grimmia pilifera.Finally,Hypnum plumaeforme,Racomitrium japonicum were recommended as ornamental mosses in vertical greening combined our observation on their landscape values. |
