摘　　要：以阿克苏河灌区为例,为探讨灌区主要作物系数、套种作物生育期内需水量及节水灌溉制度在阿克苏河灌区开展试验研究。通过一系列的试验研究,结果表明,小麦与玉米以及小麦与油葵的立体套种模式能有效起到作物各生育阶段对水量的节约与综合利用作用,在非充分灌溉制度下,小麦、玉米、油葵套种模式的产量、灌溉水利用率均比常规种植模式大幅度提升。Taking the Aksu River Irrigation District as an example,in order to explore the main crop coefficients in the irrigation area,the water demand during the growing period of the crops and the water-saving irrigation system,the experimental research was carried out in the Aksu River irrigation area.Through a series of experimental studies,the results show that the three-dimensional intercropping model of wheat and corn,as well as wheat and oil sunflower can effectively reduce the water consumption and comprehensive utilization of crops at various growth stages.Under the non-sufficient irrigation system,wheat,corn,The output of oil sunflower intercropping mode and the utilization rate of irrigation water are greatly improved compared with the conventional planting mode.
