| 摘 要： | [目的]研究分析洪水河灌区春小麦节水灌溉田间水管理系统中的几个指标。[方法]根据民乐县洪水河灌区益民灌溉试验站最近连续10年的有关资料和部分试验成果，以及在推广实施中存在的问题，对灌区春小麦节水灌溉田间水管理系统中秋灌储水指标、产量与灌水量、需水强度、需水模系数、根系分布与各阶段土壤水分控制标准几个指标进行了分析。[结果]洪水河灌区春小麦在4月上旬播种为宜：三叶期由储水供给水分．不必灌水；可在分蘖后期灌水，灌水时间为5月18—22日；头水应根据可供水量的多少来灵活掌握，在一般水文年份灌水定额应控制在980—1050m^2／hm^2；在抽穗期需灌2水，灌水时间一般为6月18—22日，定额为1050-1120m^2／hm^2。抽穗一成熟阶段若水资源紧张，可以不再灌水。[结论]确定出了适宜于洪水河灌区的春小麦节水灌溉制度。
