摘　　要：通过2年田间试验,分析河套灌区田间作物常规灌溉施氮处理与优化施氮灌溉处理对产量的影响,得出在常规灌溉施氮基础上节水节氮20%后,小麦在2009年和2010年分别增产19.51%和31.85%,葵花花盘平均总质量在2009年和2010年分别增加16.37%和18.44%。表明河套灌区节水和节氮仍具有一定的空间,优化灌溉施氮技术应大力推广。Through two years＇ field experiment,influence of conventional irrigation nitrogen treatment and optimization of nitrogen treatment on the production of loop field crops were analysised.In that conventional irrigation based on n water-saving quarter after 20% nitrogen,making the wheat in 2009 and 2010,the yield increased by 19.51% and 31.85% respectively and sunflower anxle average total is 2009 and 2010 increased by 16.37% and 18.44% respectively.The results show that,for water saving irrigation area of the loop and quarter is still has certain space nitrogen,optimize the irrigation n technology to be promoted.
