摘要
【目的】为探明草坪草对再生水灌溉的适应能力。【方法】以北京地区5种常见冷季型草坪草:高羊茅家园品种(Festuca arundinacea Schreb.‘Plantation’)、草地早熟禾优异品种(Poa pratensis L.‘Merit’)、多年生黑麦草爱神特品种(Lolium perenne L.‘Asther’)、紫羊茅派尼品种(F.rubra L.‘Penny’)和匍匐翦股颖普特品种(Agrostis plustris Hunds.‘Putter’)为试验材料,研究了生活污水、二级再生水、三级再生水和自来水等4种不同灌溉水对5种草坪草的表观质量和生理生态指标的影响。【结果】三级再生水适宜用作草坪绿化水,高羊茅家园品种"家园"最适应三级再生水灌溉,其他4种草坪草对三级再生水灌溉适应能力由强到弱依次为:"派尼">"爱神特">"优异">"普特"。
[Objective] Lawn plays an important role in maintaining ecological balance and environmental beautification. Howev- er, a large amount of water consumption in the plantation and conservation of lawn is contradicted with water shortage. Irriga- tion with reclaimed water is alternative pathway to alleviate this contradiction of water supply and demand. [Methods] In order to investigate the adaptability of turfgrass to the reclaimed water irrigation, five cool-season turfgrasses including Festuca arundinacea Schreb. ＇Plantation＇, Poa pratensis L. ＇Merit＇, Lolium perenne L. ＇Asther＇ , F. rubra L. ＇Penny＇ and Agrostis plustris Hunds. ＇Putter＇ were used as plant materials. After four irrigation water treatments, domestic wastewater, scondary-grade reclaimed water, third-grade reclaimed water, and tap water, the apparent mass and ecophysiological indexes were measured. [Results] The third-grade reclaimed water was suitable to irrigate the turfgrasses, and F. arundinacea Schreb. ＇Plantation＇ showed the highest adapability, followed by F. rubra L. ＇Penny＇, P. pratensis L. ＇Merit＇, and A. plustris Hunds. ＇Putter~.
