| 摘 要： | 为研究苗木耗水速率与气象因子的关系,对长白落叶松幼苗进行室外瓶栽蒸馏水培试验,结合气象因子,利用瓶栽称重法分析幼苗昼夜耗水速率与气象因子的相关关系。结果表明:白天,长白落叶松幼苗耗水速率与距离地面1 m处空气湿度相关性显著,与其他气象因子相关性不显著,耗水速率与近地面1 m处空气湿度呈指数性负相关;夜间耗水速率与气象因子相关性均不显著。

| Abstract: | An experimental research on the transpiration rate of Larix olgensis and meteorologic element was conducted,and the seedlings were planted in bottles with distilled water.The result showed that the transpiration rate of the seedlings was negatively exponential related to the 1 m atmosphere humidity significantly,and not significantly relative to the other meteorological elements in the day;but the transpiration rate of seedlings is no significantly relative to all the meteorological elements at night. |
