干旱沙漠绿洲区地膜玉米控制性隔沟交替灌溉节水技术研究

Study on alternative furrow irrigation on film-mulched maize in desert oasis area

针对石羊河流域干旱缺水的民勤县种植大田玉米耗水量大的实际,根据多年试验资料,研究分析了玉米控制性交替隔沟灌溉对作物生长和水分利用的影响及干旱区地膜玉米控制性交替灌溉节水高效技术的可行性。

Aimed at the situation of great water consumption on maize field in the arid area of Minqin county in Shiyang River basin, using the experiment data of 4 years, the paper analyzes the effect of alternative furrow irrigation on crop growth and water use of film mulched maize, and illustrates the feasibility of extending the technique of alternative furrow irrigation in desert oasis area.\;
