Abstract


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 firstly analyzed the physical features of four common substrates, including 100% soil, soil + rice hull + coconut fiber (2:1:1), soil + coconut fiber + rice hull + coal slag (1:1:1:1) and soil + coconut fiber + 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 fiber + rice hull + coal slag (1:1:1:1) exhibited the highest values of growth dynamics and green coverage. Additionally, the effects 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.
