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.
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 indi- ces, an integrated index revealing their growth capacity was calculated. Based on their integrated indices from high to low, six mos- ses were ranked as Hypnum plumaeforme, Racomitrittm japonicum, Thuidium cymbifolium, Campyloprts flexuosus, Dicranum scopari- um,Grimmia pilifera. FinaUy,Hypnum plumaeforme,Racomitrium japonicum were recommended as ornamental mosses in vertical greening combined our observation on their landscape values.
