| 摘 要： | 采取盆栽称质量法研究了蛇莓和五叶地锦在不同灌溉量处理下的生长状况,通过差异显著性分析确定其耐旱水平,以期为园林灌溉管理提供指导。结果表明,2006和2007年生长季蛇莓和五叶地锦在充足灌溉处理下的单株耗水量为30~40kg。随着灌溉量减少,蛇莓和五叶地锦的单叶面积、茎长、覆盖度、地上部干质量、根干质量等降低。五叶地锦可以耐受75%Mc的节水灌溉水平,而蛇莓对水分胁迫敏感,需要采取充足灌溉。 |

| Abstract: | Growth of potted seedlings of Duchesnea indica and Parthenoeissus quinquefolia at different irrigation levels was studied by weighting. Their drought-resistance was analyzed by difference significance to guide landscape irrigation management. The results showed that the water amount was 30-40 kg that one Duehesnea indiea or Parthenoeissus quinquefolia seedling consumed under the ample irrigation treatment in 2006 and 2007. The single leaf area, stem length, covering percentage, shoot drought weight and root drought weight of the two plants decreased with the irrigation. Parthenoeissus quinquefolia could accept the 75% Me irrigation level. Duehesnea indiea was sensitive to water stress and needed ample irrigation. |
