摘　　要：采用田间试验,以夏玉米为试验材料,研究了两种沟灌方式(宽垄沟灌和常规沟灌),不同水分处理对夏玉米穗部性状与产量的相互关系。结果表明:较常规沟灌,宽垄沟灌模式增产明显,平均增产率达7.990%,穗长、穗粗、穗粒数、百粒重分别增加了6.240%、3.869%、4.171%、4.610%;过低或过高的水分控制下限对产量及其构成因子都会造成不利影响;不同沟灌方式下,夏玉米穗部性状与产量的相关性均很高,均达到极显著水平;夏玉米穗长、穗粗、穗粒数及百粒重对产量均有促进作用;不同沟灌方式下,夏玉米穗部性状对产量的影响程度发生变化。Through field experiment and taking the summer corn as the experimental material, this paper studies the effects of two furrow irrigation （wide ditch irrigation and conventional furrow irrigation） on the relationship between panicle traits and yield of summer maize under different water treatment. The results show that compared with conventional furrow irrigation, the yield of wide ditch irrigation increases significantly, the average increasing rate reaches 7. 990%, spike length, spike coarse, spike grain number, hundred grain weight increases by 6. 240%, 3. 869%, 4. 171% and 4. 610%, respectively; Too low or too high moisture control limit have adverse effect on the yield and its components; Under different furrow irrigation modes, all the correlation values of panicle traits and yield of summer maize are very high and reach extremely significant level; the spike length, spike coarse, spike grain number and hundred grain weight all have a promoting effect on yield; Under different furrow irrigation, the influence degree on panicle traits and yield of summer maize has a change.
