摘　　要：为了筛选出高质量、低成本的高尔夫果岭坪床结构,通过设4个试验处理:土壤坪床(T1),纯沙坪床(T2),半改良沙基坪床(T3)和全改良沙基坪床(T4),结果表明:坪床的物理性状受诸多因素的影响,新建草坪的土壤饱和导水率和入渗率并没有达到USGA标准。随土壤中的含沙量增加,土壤饱和导水率、土壤入渗率、气体孔隙度都增加。土壤坪床总孔隙度和水分孔隙度高于沙基坪床,容重值小于沙基坪床。4种坪床的pH值显碱性,灌溉水是主要的影响因子。In order to screen the high-quality and low cost root zone structure of golf green,4 treatments ineluding soil-based root zone （T1）,pure sand root zone （T2）, mended sand root zone （T4） were conducted. The plots were properties of root zone were affected by many factors. of newly established turf did not meet the standards of pa 2 rtial amended sand root zone （T3） and fully 2m×3 m. The results indicated that the physical Soil saturated hydraulic conductivity and infiltration rate USGA. With sand proportion increasing,the soil saturated hydraulic conductivity,infiltration rate and air-filled porosity increased as well. Compared to sand-base root zone,total porosity and water-filled porosity of soil root zone were higher,and the bulk density was lower. The pH of four treatments were alkaline that was mainly caused by irrigation water.
