【目的】探究土壤水分时间变异性对作物水分利用效率的影响。【方法】以糜子为研究对象，采用盆栽试验，设置4个处理，分别为稳定性高含水率（SW1）处理、稳定性低含水率（SW2）处理、波动性高含水率（FW1）处理和波动性低含水率（FW2）处理，分析不同处理对糜子生长发育、光合作用、气孔特征、生物量分配和生理指标的影响。【结果】①与波动性土壤水分（FW）处理相比，稳定性土壤水分（SW）处理显著促进了糜子拔节期生长。在控水60 d以后，稳定性高土壤含水率（SW1）处理糜子株高、茎粗和叶面积分别较波动性高土壤含水率（FW1）处理提高了33.00%、13.04%和127.36%，稳定性低土壤含水率（SW2）处理糜子株高、茎粗和叶面积分别比波动性低土壤含水率（FW2）处理提高了51.94%、144.70%和1...
