| 摘 要： | 玉米套种马铃薯与单作相比,农田水分动态变化和作物耗水量均产生变异,受降水和土壤水分消耗的影响,最终导致不同处理的作物产量和水分利用效率出现明显差异。其中4∶4套种具有较好的产量和水分效应,水分利用率较单作玉米、单作马铃薯分别提高1.2%,10.4%。套种玉米产量12450kg/hm2,较单作玉米7950kg/hm2增产56.6%;套种马铃薯产量22500kg/hm2,较单作马铃薯19500kg/hm2增产15.4%。

| Abstract: | Study shows in dryland field of spring corn and potato,water consumption by crop is impacted and soil water dynamics is changed.As a result,different treatments get significantly different yields and water content use effectiveness .The treatment of 4∶4(Proportion of rows of corn and potato) has got a good result, water use efficiency was increased by 1.2% and 10.4% than single-planting corn or potato.Corn yield(in pure area)is 12 450kg/hm~2,potato 22 500 kg/hm~2.However,the yield of pure corn and pour potato are 7 950kg/hm~2 and 19 500 kg/hm~2 respectively. |
