摘　　要：为研究夏玉米-冬小麦连作模式下的节水灌溉制度,针对现有实时灌溉预报忽略了实际生产中复种连作的问题,统筹考虑复种连作时上下季作物生育期间隔时段内土壤水分的收支变化,建立了作物连作的实时灌溉预报模型,以三刘寨引黄灌区2014-2017年夏玉米-冬小麦连作为例进行模型的应用。结果表明:与传统灌溉制度相比,采用该模型所确定的实时灌溉制度其灌溉定额年均减少20.4%,灌区的灌溉用水量年均节省1470万m3,各年度夏玉米-冬小麦总产量分别增加2.4%、2.2%、0.8%,各年度水分利用效率分别提升13.6%、12.3%、18.3%。In order to study the water⁃saving irrigation system under the continuous cropping mode of summer corn and winter wheat,aiming at the fact that the existing real⁃time irrigation forecast ignores the issue of multiple cropping and continuous cropping in actual production and considering the changes in soil moisture in the interval between the growth periods of the upper and lower seasons during the multiple cropping and continuous cropping,a real⁃time irrigation forecasting model for continuous cropping was established.Taking the continuous cropping of summer⁃maize and winter⁃wheat of Sanliuzhai Yellow River irrigation area in the period of 2014-2017 as an example,the paper conducted the application of the model.The results show that compared with the traditional irrigation system,the real⁃time irrigation system determined by this model has an average annual reduction of 20.4% in the irrigation quota,and the irrigation water consumption in the irrigation area is saved by 14.7 million m3 per year.The total annual output of summer corn and winter wheat is increased by 2.4%,2.2% and 0.8% respec⁃tively,and the water use efficiency is increased by 13.6%,12.3% and 18.3% respectively.
