摘　　要：[目的]为了使玉米栽培充分利用土壤含水量、获取较多的光能和热能，达到高产。[方法]试验测定了玉米不同播期与小麦共生期间土壤含水量的动态变化，并分析了不同播期麦套玉米对小麦、玉米产量和玉米生长发育的影响情况。[结果]试验表明，麦套玉米不同时间套种浇水，从对小麦生长发育的影响方面来看，5月21目前后浇水有利于小麦根系的吸收和小麦产量的提高；从对玉米生长发育的影响方面来看，在麦收时玉米3叶展开期左右，即5月26日前后套种浇水对玉米的生长发育影响较小，并有利于玉米产量的提高。[结论]麦套玉米在5月21日～5月26日播种浇水为宜，既有利于小麦产量的提高，又有利于玉米的生长发育和产量的提高。[Objective ] The experiment in the full utilization of moisture in soil, light and heat in corn cultivation was conducted. [Method] The dynamic change of moisture in soil during co-growing of wheat and maize was tested and the wheat and maize yield in different wheat-owing time and the maize growth and development after wheat-sowing were analyzed. [ Results ] The test showed that in the wheat-corn intercropping field, the irrigation in about May 21 was beneficial to wheat root growth and yield-increasing. The irrigation in about May 26, when the wheat was being harvested and maize grew with 3 leaves, had not bad effect on maize growth and development. [ Conclusion ] The irrigation in the period of May 21 to May 21 to May 26 was appropriate and beneficial to wheat yield improvement.
