研究施肥量和灌水量对不同滴灌模式棉花产量、水分利用效率（WUE）的水氮耦合效应影响。
The coupling effect of water and nitrogen on cotton yield and water use efficiency(WUE) was studied under different drip irrigation patterns.
采用滴灌和渗灌栽培的灌水量显著减少，极大地提高了水分生产率。
The subsurface irrigation and drip irrigation decreased significantly the irrigation rate and increased significantly water use efficiency.
试验期间灌水采取滴灌方式，土壤水分控制以称重法和取土烘干法为主，辅以TDR法。
The irrigation way was drip irrigation during experimental time, and the control of soil water content was mainly by oven drying method as well as assistance of TDR.
