沙子对于一个球场的品质起着至关重要的作用。对工程总监来说,沙子的成本往往仅次于土方,占到整个球场建设成本的1/8甚至更高。对草坪总监来说,铺沙是球场成本最高最繁琐的工作之一。那么沙子为什么占有这么重要的位置,却不是每一个从业者都完整了解的。那让我们从植物生长和土壤的关系说起。对于绿色植物来说,它一直进行着两个过程。第一个是生产过程,维持整个生态系统的光合作用。叶绿素将水、矿物质和二氧化碳在阳光的作用下合成碳水化合物,同 Sand plays a crucial role in the quality of a course. For engineering director, the cost of sand is often second only to earthwork, accounting for the entire stadium construction costs 1/8 or even higher. For lawn regulators, sanding is one of the most costly and cumbersome courses on the pitch. So why the sand occupy such an important place, but not every practitioner have a complete understanding.
