摘　　要：用种子直播建坪的方法生产白三叶网草皮,播种时对坪床进行覆沙、土壤改良+覆沙两个处理,研究了各处理对草坪质地、密度、颜色、耐磨性和生长速度等坪用性状的影响。结果表明:坪床表面覆沙增大了草坪草的密度,表现出较好的坪用性状;结合坪床表面覆沙再进行土壤改良,能明显促进草坪草的生长、加深草坪草的颜色、增强其耐磨性,从而提高了网草皮的质量和成坪速度,是一种比较有效的建坪模式。White clover retina sod produced directly with seeds was used to carry out the experiment with two treatments, sand covering and soil amelioration＋ sand covering. Effects of different treatments on turf performance, including the texture, density, color, tramping tolerance and growth speedwere studied. The results indicated that sand covering increased the density of turf and the turf performed better compared with the control.Soil amelioration＋ sand covering could improve the growth, color and tramping tolerance of turf apparently,which increased the quality of retina sod and accelerated the development of turf.
