摘要
选择4种不同粒径大小的废旧橡胶颗粒分别与壤土、粘土、沙土组配草坪基质,通过组配基质构建草坪建植体系,研究了草坪植物的生态响应.通过对各生态指标综合效应分析,结果表明：壤土组配基质中,胶粒粒径为0.5～1mm与4～6mm组配基质要好于1～2mm和2～4mm组配基质;粘土组配基质中,1～2 mm胶粒组配基质为最好;对于沙土组配基质,1～2 mm和2～4mm粒径的胶粒组配基质要优于0.5～1mm与4～6mm的组配基质.比较发现,从草坪植物生长角度来看,以沙土填充废胶粒为介质组配运动场草坪基质具有较好的应用前景.
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.
