Authors studied two samples： the first with totally modified top soil following the USGA （United States Golf Association） Specifications, all new top soil, as in USGA, called the Texas method; the second sample was natural soil mixed with ammendants and sand, in order to reduce compaction. This study compares the initial investments, performance during training and finally the cost of maintenance. The drainage system was the same for both samples.展开更多
详细介绍了美国高尔夫球协会果岭部(USGA Green Section)推荐的最新版(2004)USGA果岭建造标准方法。与1993年标准相比,新方法在以下一些方面做了改进:根层混合物的渗透率要求有所降低、根层铺设厚度的允许误差范围增大、砾石的选择范围...详细介绍了美国高尔夫球协会果岭部(USGA Green Section)推荐的最新版(2004)USGA果岭建造标准方法。与1993年标准相比,新方法在以下一些方面做了改进:根层混合物的渗透率要求有所降低、根层铺设厚度的允许误差范围增大、砾石的选择范围放宽、允许使用无机土壤改良剂、排水管道可选用新型材料等等。这使得各种建造材料更容易获得,有利于降低建造成本。同时有助于提高我国球场果岭的建造水平,增强高尔夫从业人员科学建造果岭的意识,对促进我国高尔夫运动的发展起到积极的推动作用。展开更多
