以盆栽玉米为试材，研究控制性分根交替滴灌供水方式下，不同处理蒸腾速率的日变化。
The diurnal change of transpiration rate of maize in different disposals was studied in potted experiment under the alternative drip irrigation for the control of root.
各处理苜蓿不同深度处根重占总根重的百分率随土壤深度的增加呈对数关系，相关系数均超过了0.9623。
There existed logarithm relations between the layer weight of roots and soil depth with the correlation factor of over 0.9623. The weight of roots decreased rapidly with the increase of soil depth.
