| Abstract: | A field experiment was carried out in 4 years to determine optimal irrigation schedule for maize mulched with plastic film under different irrigation methods, such as border irrigation, conventional furrow irrigation, controlled root divided alternative furrow irrigation (CRAFI) and wide ridge furrow irrigation, in Minqin Oasis of Shiyanghe basin. The effects of irrigation methods and irrigation schedules on yield and water use efficiency of maize were also discussed and analyzed. The best results occurred in the areas irrigated with CRAFI method and with schedule of irrigating 7 times, with irrigation quote of 300 m 3/hm 2 at stage of shooting, big bulge, heading, tasseling, early filling, middle filling and late filling respectively. |
| Keywords: | Minqin Oasis controlled root divided alternative furrow irrigation (CRAFI) irrigation schedule |
