摘　　要：基于田间试验,研究了常规沟灌、固定沟灌和交替沟灌对花生水分入渗规律及水分利用效率的影响。结果表明,交替灌溉有助于减少深层渗漏,减少水分损失。湿润峰的位置有助于花生对水分的吸收。交替灌溉产量、总水分利用效率和灌溉水利用效率比常规灌溉提高了325.83kg/hm2、0.297kg/m3和2.04kg/m3。交替灌水是一种经济可行的方法。Field experiments were carried out to study the effects of three irrigation methods on the water irrigation infiltration law and utilization efficiency of the peanut. The results showed that, alternate irrigation could decrease the deep infiltration and water loss. The wet peak position could help peanuts to the absorption of moisture. Yield, total water use efficiency and the irrigation water use efficiency under alternate irrigation were 325. 83 kg/m^3, 0. 297 kg/m^3 and 2. 04 kg/m^3, which were apparently higher than those under conventional irrigation, respectively. So, the alternate irrigation is an economically feasible method.
