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。
Peat is a common soil improvement material. In this paper, different peat samples from the market were analyzed for their quality, and their physical properties on the golf course green ridge beds were studied. Scientific basis. The results showed that: (1) The quality of peat samples from different sources such as pH, crude organic matter, total humic acid content and cation exchange capacity were significantly different. The quality of German imported peat was superior to that of domestic peat. (2) The addition of a certain proportion of peat to the sand sample can significantly change the physical properties of the sample, such as the decrease in permeability, bulk density and aeration porosity, while the total porosity, capillary porosity and water holding capacity increase. The higher the proportion of peat added, the finer the particles, the more obvious this change.
