Tree-scale transpiration dynamics of Hedysarum scoparium in response to growth stage, groundwater table depth, and climate in a semi-arid environment in northwestern China
甘肃民勤地区不同地下水埋深花棒蒸腾耗水研究

Natural precipitation is often limited and groundwater can be a very important water source for vegetation reestablishment and growth in the dryland regions. Therefore, quantifying water use by plant transpiration under different ground water tables helps to understand responsive mechanism of plant growth to various ground water regimes. One year-old seedlings of Hedysarum scoparium were planted in 1995 and single tree transpiration dynamics under constant water tables of 1.6 m, 2.6 m, and 3.6 m were measur...
