摘要
结合膜孔灌溉技术的特点,利用正交试验设计方法设计了实验方案,利用田间试验资料,分析研究了春玉米膜孔沟灌条件下水分利用效率及水分消耗规律,并相应得出春玉米地膜覆盖条件下各个生育期的水分消耗系数,为膜孔沟灌技术推广应用提供了理论和技术依据。
Based on the characteristics of film hole irrigation, by making use of the results of orthogonal experiment, this paper analyzed water use efficiency and water consumption rule of spring corn under film hole furrow irrigation, and educed water consumption coefficients of film-mulched spring corn in different growing periods, so as to provide theoretical and technical basis to the widespread application of film hole furrow irrigation.
