摘要
利用大型称重式蒸渗仪和微型蒸渗仪研究了冬小麦生育期间逐日蒸散和蒸发过程 ,分析了蒸发占蒸散的比例及其随叶面积指数和表层土壤含水量的变化关系。
A large scale weighing lysimeter and main microlysimeters are applied to study diurnal changes of evapotranspiration and soil evaporation in different growing stages of winter wheat. Ratios of soil evaporation to evapotranspiration in each growing stages of winter wheat are investigated. The effects of soil moisture and leaf area index on the ratio of soil evaporation to evapotranspiration, and the change of soil evaporation after irrigation are also analyzed.
