| 摘 要： | 以位于我国北方大连市中心劳动公园内一种混合草坪为研究对象,采用微型蒸发皿对其耗水量进行研究,根据水量平衡的原理,分析蒸发皿内植株的蒸腾耗水量及土壤水分动态的变化。结论为:草本植物典型天气耗水量日变化显示,5-10月的日耗水量基本都是晴天与半晴天大于阴天,晴天的日耗水量略大于半晴天,6、7、8、9月份的日耗水量大于5月和10月的日耗水量;草本植物典型天气昼夜耗水显示,草本植物在晴天和半晴天的耗水量80%以上都发生在白天,在阴天,70%以上发生在白天,夜间耗水量在阴天有所增加;草本植物在2008年整个生长季的耗水量排序为:8月9月7月6月5月10月,因为7月阴雨天较多,其蒸腾耗水量有所减少。草坪生长季内总耗水量为274.19mm。

| Abstract: | A micro-lysimeter experiment was conducted to study the water consumption characteristics of a multi-species lawn in Dalian Labor Park. The dynamic changes of soil moisture and water consumption in the herbage plants within the evaporating dish were analyzed according to the water balance principle. Results indicated that daily water consumption of the herbage plants on sunny days was a little bit higher than that on medium sunny ones,but the herbage plants on both sunny days and medium sunny days showed mo... |
