| 摘 要： | 为了解蛇莓和五叶地锦在北京地区的蒸散耗水(ET)规律,2006年利用小型蒸渗仪,采取蒸散量反馈式灌溉方法研究100%ETEc、75%ETc、50%ETc、25%ETc 4个灌溉水平下的蒸散和生长。结果表明,2006年6月~10月100%ETc灌溉水平下蛇莓和五叶地锦的蒸散总量分别为474.94mm、493.94mm。不同灌溉水平下蛇莓的蒸散曲线基本一致,均在7月达到蒸散高峰。五叶地锦7月和9月蒸散较强,100%ETc和75%ETc处理下9月的蒸散量高于7月,而50%ETc和25%ETc处理下7月的蒸散量高于9月,说明长期的控制灌溉处理抑制了植株生长,使9月的蒸散降低。生长测定结果显示,蛇莓对水分胁迫比五叶地锦更敏感,五叶地锦在75%ETc的轻度干旱胁迫下可基本维持观赏性,而蛇莓要求100%ETc的灌溉水平。 |

| Abstract: | To get the evapotranspiration(ET)rule of Duchesneaindicaand parthenocksus quinquefolia in Beijing,ET and growth of these two ground cover piants were researched in mini-lysimeter by means of ET feedback irrigation method at digerent levels as 100%ETc,75%ETc,50%ETc,25%ETc in 2006.The results showed that the total ET during July to October in 2006 of D.indica and P.quinquefolia was 474.94mm and 493.94mm respectively.The ET curves of D.indica at diferent irrigation levels were similar,with the ET peak of Juiy.... |
