| 摘 要： | 水资源短缺，城市用水紧张，使得草坪灌溉用水管理受到极大关注。为了研究草坪修剪管理的节水效果，采用小型排水式蒸渗仪，通过田间实验研究了充分供水条件下3种草坪草(早熟禾、高羊茅、黑麦)不同修剪高度(留茬高度：5、10、15 cm和不修剪)处理对耗水量的影响，并根据水量平衡原理计算得到了3种草坪草的耗水量。研究结果表明：草坪草的耗水量均随修剪留茬高度增加而增加，不同草种间存在差异。3种草坪草修剪留茬高度为5 cm时较不修剪耗水量减少36.78%(早熟禾)、34.02%(高羊茅)、33.54%(黑麦)，平均减少耗水量34.78%。所得参数可以为类似地区3种草坪草灌溉系统的规划设计和节水管理提供基础理论依据。

| Abstract: | Water resources shortage in cities causes great attentions on the irrigation management of turf grasses. To improve the water efficiency of turf grasses, the effects of mowed heights(5, 10, 15 cm and without mowing) of three kinds of turf grasses(Poa pratensis, Festuca arundinacea, Lolium perenne) on water consumptions were studied using portable lysimeters under full water supply conditions. Water consumptions of the three kinds of turf grasses were estimated from experimental data with water balance model. Results show that water consumptions increase with the increase of mowed heights of turf grasses, which differed for different species. The reducing percentage of water consumptions for the grasses mowed to 5 cm height are 36.78%(Poa pratensis), 34.02%(Festuca arundinacea) and 33.54%(Lolium perenne) compared with unmowed grasses. 34.78% of average water consumption is expected to be consumed. The determined parameters are useful for the planning and management of irrigation systems of three kinds of turf grasses in the areas under similar conditions. |
