1.1本指南涵盖了维护用于天然表面运动场的冷季草坪的最低要求。涵盖的实践包括割草、施肥、灌溉、核心栽培、监督和害虫管理。 1.2维持高质量自然运动场地的决策应考虑土壤类型、当地气候和其他因素；因此，建议您联系当地的合作推广服务机构，以获取有关适合您所在地区的土壤、草种和品种的更具体信息。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 比赛场地上密集、均匀的草坪为运动员提供了坚实的基础，并缓冲了他们在摔倒或铲球时的冲击力，从而提高了比赛质量和场地安全。这些标准是提供此类表面所需的最低输入。本指南的编制过程中使用了各种已出版的指南 (1- 5. ) . 2. 场地条件可能直接影响因使用场地而发生的运动损伤的频率和类型。 虽然这些标准不能保证能够防止此类伤害，但在自然场地上维护良好的草皮应尽量减少与场地相关的伤害。

1.1 This guide covers the minimum requirements for maintaining cool season turfgrasses used for natural surface athletic fields. Practices covered include mowing, fertilization, irrigation, core cultivation, overseeding, and pest management. 1.2 The decisions involved in maintaining a quality natural playing surface should consider soil types, local climate and other factors; therefore, it is recommended that you contact your local cooperative extension service for more specific information on soils, and grass species and cultivars adapted to your area. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== A dense, uniform stand of turfgrass on a playing surface improves the playing quality and safety of the field by providing firm footing for the athletes and by cushioning their impact from falls or tackles. These standards are the minimum inputs required to provide such a surface. Various published guides have been used in the development of this guide (1- 5 ) . 2 Field conditions may directly influence the frequency and type of athletic injuries occurring as a result of using the fields. While these standards do not guarantee that such injuries will be prevented, a well-maintained turf on a natural playing surface should minimize field-related injuries.
