蒸腾计：通过茎切段或整个植物体来测量水分吸收速率的仪器。
Potometer an apparatus for measuring the rate of water uptake by a cut shoot or whole plant.
用蒸腾计法和解剖学方法分别研究了氮亏缺对玉米单根径、轴向导度的影响。
The results indicated that N deficiency decreased root radial and axial hydraulic conductivity of maize.
通常与由于蒸腾作用而丧失水分的速率紧密相关，蒸腾计可被用于在不同条件下进行蒸腾速率的比较。
This is normally closely related to the rate of water loss by transpiration and the potometer can be used to compare transpiration rates under different conditions.
通过田间试验及理论计算，验证了对茎流计在测量作物蒸腾方面的实用价值。
Stem flow gauge can measure plant flow rate directly. In this paper, we have evaluated the value of the instrument through farmland experiment and theory calculation.
