| 摘 要： | 在甘肃河西走廊高海拔冷凉区以莴笋＂太原笋＂为试材,研究了常规沟灌（CFI）、固定隔沟灌溉（FFI）、隔沟交替灌溉（AFI）对莴笋生长、生理特性、产量及水分利用效率的影响。结果表明,隔沟交替灌溉（AFI）模式下莴笋的茎粗、茎重、产量、叶片净光合速率、蒸腾速率与常规沟灌（CFI）模式下无显著差异。AFI较CFI节水22.2%、水分利用率提高26.9%,实现了经济产量不降低。莴笋上应用隔沟交替灌溉技术具有较大的节水潜力。

| Abstract: | To explore new high-efficient water-saving irrigation methods in arid areas,a field experiment is carried out to investigate the effects of alternate furrow irrigation on the growth,physiological characteristics,yield and water use efficiency of asparagus lettuce in high-altitude arid areas of Hexi Corridor.Planting is applied with three partial root zone irrigation methods.i.e.conventional furrow irrigation(CFI,),fixed furrow irrigation(FFI watered),and alternate furrow irrigation(AFI).The results show tha... |
