摘要
城市高架道路绿化采用悬挂式花槽,固定在防冲墙外侧。花槽的材料用PVC塑料制作,比不锈钢、玻璃钢材料更经济、轻巧、美观、耐用。花槽底部有蓄水层,可减少浇水次数。栽培介质用轻质土,以减轻花槽重量。高架道路上植物生长条件恶劣,经筛选黄馨、粉团蔷薇,日本无刺蔷薇三个品种,两年多来在高架道路上生长和景观效果良好。
Plants decorating urban viaducts are contained in flower troughs hung on the outside of the protection walls. The flower trough is made up of PVC is cheaper, lighter in weight and lasting longer. There is a water - retaining layer at the bottom of the flower trough which reduces irrigation. The medium is made up of light materials so as to reduce the weight of the trough. It is obvious that most plants cannot grow well on the viaduct. After many trials in the past two years three cultivars Jasminum mesnyi, Rosa mulliflora var cathayensi and Japanese spineless rose have grown well and have had a good landscaping effect.
