Abstract
Abstract In this study, the authors designed and applied a new irrigation method called capillary wicking irrigation (CWI), which used microfiber fabric as the source material of irrigation. At present, the effects of CWI on soil moisture, plant growth and surface temperature of a green roof with rain storage are not clear. An experiment was conducted on a green roof in Guangzhou. The authors set three transparent Plexiglas containers (A, B and C) with a side length of 1.5 m as an experimental frame on the roof. The authors put ‘steering wheel’ microfiber CWI in containers A and C, which were planted with Sedum lineare Thunb and Fittonia verschaffeltii, respectively. Container B with no CWI was planted with Sedum lineare Thunb. Results indicated that CWI could increase soil water content and make the variation of soil water content gentle in the containers on the roof. The green roof with rain storage had the function of heat preservation in winter and cooling effect in summer, especially for the green roof with CWI. Compared with container B, container A gave better plant growth, for ‘steering wheel’ microfiber CWI can basically provide automatic and suitable water supply for the plant. Therefore, CWI is an effective infiltration irrigation technique for roof greening.
