成都地区布袋式墙面绿化植物的筛选

Screening of the Bag-type Wall Greening Plants in Chengdu Area

以蓝羊茅、千叶兰、针茅等8种植物为材料,采取布袋式墙面绿化栽培试验,以存活率、生长势、生长指数和覆盖度为考察指标,通过相应指标的隶属函数值来评价植物的生长适应性,从而筛选适宜成都地区室外墙面绿化的植物品种。结果表明:千叶兰、南天竹的生长适应性强,观赏价值高,适宜应用于成都地区室外布袋式墙面绿化;红花檵木、黄金菊、金叶六道木、红花酢浆草4种植物的生长适应性不强,受气候环境变化影响大,气候环境适宜时生长势高,观赏效果较好,可适当选择小面积应用于小气候环境较好的项目;蓝羊茅、针茅的生长适应性差,景观效果不理想,不适宜用于成都地区室外布袋式墙面绿化。

Based on the bag-type wall greening cultivation test,using 8 plants such as Festuca glauca,Muehlewbeckia complexa,Stipa capillata as material,and survival rate,growth potential,growth index and coverage ratio as examining indexes,by evaluating the adaptability of plants using the membership function of corresponding indexes,plants suitable for the bag-type wall greening outdoor in Chengdu area were screened.Muehlewbeckia complera and Nandina domestica had strong adaptability and high ornamental value,and were suitable for the outdoor bag-type wall greening in Chengdu area.Loropetalum chinense var.rubrum,Euryops pectinatus,Abelia grandiflora‘Francis Mason’,Oxalis corymbosa were greatly affected by the climate and environment with low adaptability.When the climate and environment are suitable,they have high growth potential and good ornamental effect.Therefore,small areas can be appropriately selected for projects with better microclimate environment;Festuca glauca,and Stipa capillata had bad adaptability and poor ornamental value,so they are not suitable for outdoor bag-type wall greening in Chengdu area.
