摘　　要：为了更为合理地推广应用大垄双行膜下滴灌技术,本文选用玉米浚单20和辽单535为试验材料,研究了不同灌溉制度对玉米生长、产量和水分利用效率(WUE)的影响。结果表明:不同品种之间,营养生长和产量性状差异显著,但同一玉米品种控制灌溉条件下,株高、叶面积指数(LAI)、地上物质干重/鲜重、穗长、穗粗、穗粒数、百粒重和穗粒重等均得到明显提高,秃尖长减小;控制灌溉具有明显的节水增产效应,浚单20和辽单535分别增产11.6%和8.8%,WUE分别提高22.1%和19.1%,因此,通过控制灌溉技术制定灌溉制度,将有利于大垄双行膜下滴灌技术优势的进一步发挥。In order to popularize the technology of planting maize in double row at one wide ridge with mulch-drip irrigation, effects of irrigation scheduling on the growth, yield and water use efficiency （WUE） were studied in this paper with ‘Jundan 20＇ and ‘Liaodan 535＇ as the test crops. The results showed that vegetative growth and yield components varied significantly between the two varieties. However, stem length, leaf area indexes （LAI）, the fresh weight and dry weight of the matter above ground, ear length, ear coarse, kernels per spike, spike grain weight of the same variety were promoted while the length of barren ear tip decreased by controlled irrigation. Moreover, yield and WUE were both increased by controlled irrigation, yield of ‘Jun-dan 20＇ and ‘Liaodan 535＇ increased by 11.6% and 8.8% separately while WUE increased by 22.1% and 19.1%. Therefore, the technology of double row at one wide ridge with mulch-drip irrigation would be better used if the technology of controlled irrigation was combined.
