摘　　要：依据田间试验,研究了井渠双灌条件下河套灌区小麦和向日葵的灌溉制度。结果表明,Jensen模型最能较好地表达研究区小麦、向日葵井渠双灌条件下各生育阶段水分的量化关系。小麦和向日葵整个生育期均需灌水4次,灌水量分别为67.5、75、75、67.5mm和75、67.5、67.5、52.5mm。小麦拔节—开花期、向日葵现蕾—开花期适合井灌,灌水量分别为75、67.5mm,相应其他生育阶段均采用渠灌。Field experiments were conducted to study the irrigation schedules of wheat and sunflower under well-canal in Hetao irrigation district. The results showed that Jensen model could well describe the water quantitative relationship in each growing stages of wheat and sunflower under well canal irrigation mode. The wheat and sunflower both should be irrigated four times in the whole growth period, and the irrigation quotas were 67.5 mm, 75 mm, 75 mm, 67.5 mm and 75 mm, 67.5 mm, 67.5 mm, 52.5 mm respectively. The jointing to flowering stage of wheat and the squaring to flowering stage of sunflower were suitable for well irrigation, the irrigation quotas were 75 mm sponding other growth periods. and 67.5 mm, and canal irrigation could be used in torte-
