摘  要：
对28种沙分别与泥炭按75∶25比例混配而成的高尔夫果岭坪床材料的物理性状进行了测定,并根据USGA果岭建造推荐标准对结果进行了评价,以确定果岭坪床材料沙的适宜性选择指标及其范围。在28种沙中,粒径指数D10变化范围为0.07mm~0.33mm,D20为0.09mm~0.44mm,D50为0.17mm~0.83mm,D90为0.24mm~3.05mm,均一性指数D90/D10分布范围为2.60~25.00。评价结果表明,28种坪床材料的总孔隙度和导水率基本上能满足要求,合格率分别为100%和75%,而毛管孔隙度和通气孔隙度则较难达到标准,合格率分别为32%和36%;全部4项指标均符合的只有4种,有3项指标合格的有6种。进一步分析认为,判断一种沙是否适合作坪床材料,最简便的方法是根据沙的小粒径(D10)、大粒径(D90)及其均一性(D90/D10)的变化范围来确定,相应的适宜范围小粒径(D10)为0.15mm~0.30mm,大粒径(D90)为0.50mm~3.00mm,均一性(D90/D10)为3~13。

摘  要：
The physical properties of putting green rootzone mixes were tested using twenty-eight different sand materials mixed with peat at a ratio of 75/25 sand/peat,and evaluated according to the USGA recommendations for putting green construction,in order to determine the characteristics and their ranges of sands suitable for rootzone.The results showed that the ranges of sand size D_(10),D_(20),D_(50),D_(90) and sand uniformity D_(90)/D_(10) were 0.07mm～0.33mm,0.09mm～0.44mm,0.17mm～0.83mm,0.24mm～3.05mm and 2.60～25.00 respectively.In the twenty-eight different mixes,100% of mixes in total porosity(at-3KPa matric potential),75% in hydraulic conductivity,32% in capillary porosity,and 36% in air-filled porosity fell into the USGA recommendations.Only four mixes met the above all four physical properties and six mixes reached the three.A sand that would be suitable for rootzone depended on sand size D_(10)(smaller particles),D_(90)(larger particles),and sand uniformity D_(90)/D_(10).It is considered that the ranges of sand size D_(10),D_(90),and sand uniformity D_(90)/D_(10) suitable for green rootzone are 0.15mm～0.30mm,0.50mm～3.00mm,and 3~13.
