【国外标准】 Standard Guide for Construction and Maintenance of Grass Tennis Courts

4.1 A grass tennis court should provide a relatively uniform, high quality playing surface as it relates to footing and ball bounce. Undulations, rough surface, bare spots, weeds, and wet spots detract from good play. Playing surface quality is largely affected by construction and maintenance procedures, and this guide addresses those procedures.4.1.1 During construction, consideration should be given to factors such as soil physical and chemical properties, freedom of large stones and debris in the soil, surface and internal drainage, grass species selection, orientation of the court, and provisions for distributing wear on the playing surface.4.1.2 Maintenance practices that influence the playability of the surface include mowing height, mowing frequency, rolling, irrigation, fertilization, weed control, disease and insect control, cultivation, thatch control, topdressing, and overseeding.4.2 Those responsible for the design, construction, or maintenance, or a combination thereof, of tennis courts will benefit from this guide.4.3 This guide provides flexibility in choices of procedures and can be used to cover a variety of use and budget levels.1.1 This guide covers techniques that are appropriate for the construction and maintenance of grass tennis courts. This guide provides guidance for selection of soil systems and turfgrass species in court construction and for selection of management practices that will maintain an acceptable playing surface.1.2 Decisions in selecting construction and maintenance techniques are influenced by existing soil types, climatic factors, adaptation of grass species, level of play anticipated, intensity of use, budget, equipment, and training and ability of the turf management personnel.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
