摘　　要：针对当前城市绿化面积不断增加、草坪耗水量需求巨大现状,提出雨水灌溉观念并开展实验。利用非常规水源——库存雨水与自来水灌溉高羊茅草,分析在不同水源不同水分梯度灌溉条件下,高羊茅草在相对生长速度、叶绿素及光合作用等不同方面的生理生态指标的差异性,确定库存雨水灌溉高羊茅草的可行性和优越性。并为利用雨水灌溉长江中下游地区草坪草提供依据。Basing on the increasing need of green scale and water demand of the lawn,bringing forward the concept of using rain as irrigation resources,and having carried out experiments.Irrigating Tall Fescue with unconventional water resource——storage rain,contrasting the tap water under the same water condition,comparing the differences between the comparative growth、chlorophyll and photosynthesis,to ensure the feasibility and advantage of using rain as irrigation resources,and to provide the basis for the rain irrigation on grassplot in the middle and lower reaches of the Yangtse River.
