中文摘要 | 以塑膠容器作為綠屋頂的材料,具備耐用、質輕、經濟等優點。然而塑膠容器易導致介質的高溫而影響植物生長。如能在塑膠容器表面開設孔洞,可降低介質溫度,將有利於植物生長。因此本研究目的旨在探討塑膠容器的開孔率對介質溫度的影響。以不織布容器(開孔率P100%)及塑膠容器三種開孔率(P40%, P20%及P0%)為處理,在介質表層、表層以下5cm、10cm及15cm設置熱耦線,紀錄62天的介質溫度變化。結果顯示溫度分佈可分為兩群,群I為P100%及P0%,群II為P40%及P20%。群I高於群II 0.51∼ 2.02℃。開孔率100%及0%的容器在5 cm及10 cm處,各有一天超過根部的適生臨界溫度37.8℃。建議塑膠容器有適當的開孔率將可有效降低介質溫度。 |
英文摘要 | Plastic containers are durable, light and inexpensive when used in green roofs . However, plastic containers produce high substrate temperatures that can injure plant growth. A porous container wall may promote the plant growth. Therefore, this study clarifies the relationship between container porosity and the substrate temperature. Four treatments were used, with porosities of 100%, 40%, 20% and 0% (P100%, P40%, P20% and P0%). Thermal couples were set up at the substrate surface, under substrate of 5 cm, 10 cm and 15 cm. The temperature in the substrate was recorded from Aug, 04, 2015 to Oct, 04, 2015. It revealed that the substrate temperatures were divided into two groups. Group I were P100% and P0%, group II were P40% and P20%. The substrate temperature of group I were higher than group II 0.51∼2.02℃. Thus, an adaptive porosity of P40% or P20%, for example, can reduce substrate temperature effectively. |
