摘　　要：为了探究位山灌区冬小麦合理的水肥管理措施,采用田间试验的方法,研究冬小麦关键生育期不同灌水量与施氮量对冬小麦生长和产量指标株高、穗长、穗粒数、千粒质量的影响。结果表明:施肥量通过影响穗数及穗粒数影响冬小麦最终产量,灌溉量通过影响籽粒质量影响冬小麦最终产量;水肥互作效应下,灌溉量对冬小麦产量的影响比施肥量更明显;连续3 a的试验结果显示,灌水定额为675 m 3/hm 2、施氮量为198 kg/hm 2的水肥措施有利于当地冬小麦的生长发育及增产。To investigate reasonable water and fertilizer management treatments for winter wheat in Weishan irrigation area,the field experiments method was used to study the influence of different irrigation volumes as well as fertilizing amounts on the growth and yield of winter wheat including plant height,ear length,number of grain per spike,and 1000-grain mass.The results show that the fertilizing amount affects the final yield of crops in the way of spike number and grain numbers per spike,while the irrigation volume in the way of grain mass.Under the interaction of water and fertilizer,the irrigation volume has more obvious effect on winter wheat yield than that of fertilizing amount.The consecutive experimental results for 3 a indicate that the treatment condition of irrigation volume 675 m 3/hm 2 and fertilizing amount 198 kg/hm 2 is the best choice for the improvement of winter wheat growth and yield.
