Abstract:Turf media were respectively compounded by loam, clay soil, sand and waste crumb rubber with four different sizes as soil amendment, and ecological responses of turfgrass were investigated. Analysis on synthetical effect of all ecological indices showed that in soil compounded media, compounded medium with 0.5~1 mm and 4~6 mm crumb rubber was better than 1~2 mm and 2~4 mm. However, compounded medium with 1~2 mm crumb rubber achieved better results in clay soil compounded media. Moreover, in sand compounded media, 1~2 mm and 2~4 mm crumb rubber was better than 0.5~1 mm and 4~6 mm. By comparison, from the angle of turfgrass growth, compounded medium by sand and waste crumb rubber as soil amendment has better applied prospect.
