摘　　要：本文对目前生产上常用的8个小麦节水品种在不同灌水条件下进行了产量、水分生产效率、形态和产量构成因素等指标的比较研究。结果表明:整个生育期中灌3水处理与灌4水处理相比,8个小麦品种的灌溉水量平均减少1050m3/hm2,而产量均无任何下降,平均水分生产效率提高0.54kg/m3。影响小麦灌1水条件下产量和水分生产效率高低的一个重要因素可能是小麦本身在水分胁迫后穗粒数是否显著增加。A comparison of the yield、 WUE,morphology and factors of yield among 8 water-saving wheat varieties in different irrigation condition was studied in this article. The average yield and WUE of the 8 wheat varieties under four times irrigation during the whole growing period are all higher or equivalent to those under three times irrigation during the same period, while the total volume of irrigation water was saved by 1 050 m3/hm2, and the average WUE was increased by 0.54 kg/m3. The seeds per panical of wheat variety may be the main factor affecting the yield and WUE of the wheat under one time irrigation during the whole growing period.
