摘要: 污水灌溉是污水资源化的重要途径。本研究以三种典型的冷季型草坪草草地早熟禾、多年生黑麦草、高羊茅为供试草种,以自来水和经过砂过滤和沉淀处理的城市居民小区的生活污水为灌溉水源,采用地下滴灌和渗灌两种灌水方法,通过田间对比试验,探讨了污水灌溉条件下草坪草的耗水规律。结果表明,污水灌溉条件下草坪草耗水量与清水灌溉条件下草坪草耗水量差异不显著;污水灌溉条件下草坪草耗水规律和清水灌溉条件下草坪草耗水规律呈相似的变化趋势。在此基础上,结合北京地区的有关气象资料,初步分析制定了不同降雨年型草坪污水灌溉制度,为北京市城市草坪污水灌溉管理提供参考依据。

Abstract: Sewage effluent is considered as an important water resource which can be reused for irrigation. An experiment has been conducted for investigating the rule of water consumption with three species of turfgrasses:kentucky bluegrass(Poa pratensis), perennial ryegrass(Lolium perenne), and tall fescue(Festuca arundinacea); two kinds of irrigation water resources:tap water and sewage effluent; and two kinds of irrigation methods:subsurface dripping irrigation and subsurface leaky pipe irrigation. The results indicate that there is no significant difference with the turfgrass water consumption and change of amount, whether it is irrigated with sewage effluent or clean water. On the basis of the study and combining the meteorological statislics of the past 13 years(1988~2000) of the Beijing area, we submit a plan of turf irrigation for consideration to the Beijing turf management and sewage effluent irrigation office, together with data of soil moisture and water consumption in three different annual precipitation conditions.
