摘　　要：草炭是一种较为常见的土壤改良物质,本文对取自市场上的不同草炭样品进行了品质分析,同时研究了它们对高尔夫球场果岭坪床物理性质的影响,为运动场草坪坪床的建造提供科学依据。研究结果表明:(1)不同来源的草炭样品在品质上,如pH、粗有机质、腐殖酸总量和阳离子交换量等方面均存在显著差异,德国进口草炭在品质上明显优于国产草炭。(2)在砂样中添加一定比例的草炭,能显著改变样品的物理性质,如渗透率、容重和通气孔隙数量降低,而总孔隙度、毛管孔隙度和持水力增加。草炭的添加比例越高、颗粒越细,这种变化越明显。Some peat samples collected in the market were investigated to compare the difference of properties. The effect of peat on the physical properties of rootzone on Green was also researched. The results showed that： （1） There were significant differences on the properties of peats, such as organic matter, humic acid and CEC. （2） The physical properties of sand could be obviously influenced by adding peats. When sand was mixed with peat, the percolate rate, bulk density and air-porosity could he decreased. On the other hand, the total porosity, capillary, porosity and water retention could be increased. The more peats and the finer peats were, the influence on physical properties was more obvious.
