%X Establishment of the green space in urban environment has been regarded as one of the major strategies for the development   of green cities. In this study, we provided experimental evidence for the uses of biochar-based substrates for the growth and   development of blue daze (Evolvulus glomeratus) plants under the rooftop condition. We frstly analyzed the physical features   of four common substrates, including 100% soil, soil+rice hull+coconut fber (2:1:1), soil+coconut fber+rice hull+coal   slag (1:1:1:1) and soil+coconut fber+rice hull+coal slag (1:2:2:1) to gain an advantages under the rooftop condition.   Subsequently, the evaluation of the growth and development of the blue daze (Evolvulus glomeratus) in four formulas under   the rooftop condition was investigated. Among them, the use of soil+coconut fber+rice hull+coal slag (1:1:1:1) exhibited   the highest values of growth dynamics and green coverage. Additionally, the efects of three thicknesses (5, 8, and 12 cm)   of a selected formula were tested under the rooftop condition. The results revealed that the surface area of green coverage   exhibited the highest value, by 1964.13 cm2   at 90 days after planting in a depth layer of 8 cm. Taken together, our study could   provide a solid foundation for further cultivation of blue daze plants under the rooftop condition.
