【目的】探究不同播种方式和播种量对春小麦耗水特征及水分利用效率的影响。【方法】采用裂区试验，主区为播种方式：设宽幅匀播和传统条播2种模式；副区为不同播种量：设D1：390 kg/hm2、D2：420 kg/hm2、D3：450 kg/hm2、D4：480 kg/hm2和D5：510 kg/hm2共计5个水平，研究了不同播种方式和播种量下的春小麦耗水量、产量和水分利用效率。【结果】播种量是春小麦各阶段耗水量的主要影响因子，播种方式与播种量对春小麦拔节—乳熟、乳熟—完熟阶段的耗水量具有显著交互作用。宽幅匀播春小麦耗水量在D4处理时达到最大值，而传统条播春小麦耗水量最大值出现在D3处理；宽幅匀播D2、D4、D5处理较传统条播春小麦籽粒产量分别增加5.3%、21.0%和28.3%；宽幅匀播D4处理产...
