河西干旱区冬季免储水灌溉结合坐水种技术对春小麦出苗率和产量的影响
Effects of Winter Storage Irrigation Combined with Production Techniques of Water Sitting on Seedling Emergence Rate and Yield of Spring Wheat in Hexi Arid Area
摘要
Abstract
[Objective]The purpose of this research was to improve the mode of winter storage irrigation in Hexi arid area. [Method]Field experiments were carried out in Hexi irrigation area. The effects of four different irrigation-tillage treatments on seedling emergence rate and water use efficiency(WUE) of spring wheat were studied. Four treatments were convention winter storageirrigation(CI), low norm storage irrigation(LI),no tillage-no storage irrigation-sowing with water(NTSW) and no storage irrigation-sowing with water(NISW). [Result]The result showed that the seedling emergence rate of the four treatments had little difference. Compared to CI, the seedling emergence rate of LI, NTSW and NISW were only decreased by 1.78%, 1.98% and 2.44%,respectively,and the yield of LI, NTSW and NISW were only decreased by 12.87%, 5.02% and 9.16%,respectively.But the WUE of LI, NTSW and NISW were 0.22,0.21,0.33 higher. [Conclusion]This research will provide the theoretical references for achieving efficiently utilization of water resources.关键词
