| 摘 要： | 在同一种植密度下,设3种种植模式,包括25 cm等行距平作、"20+40"大小行平作和"20+40"沟播。研究了冬小麦沟播和平作种植对产量及水分利用效率的影响。结果表明,"20+40"沟播产量显著高于平作;叶片相对含水量(RWC)、水势(Ψw)和叶片水平水分利用效率随生育进程的推进呈整体下降趋势,其中,沟播处理RWC、Ψw和叶片水平水分利用效率的平均值均显著高于等行距和"20+40"平作处理;另外,"20+40"沟播还能明显提高冬小麦田土壤贮水量,减少总耗水量,从而提高水分利用效率。灌水增加了冬小麦产量和叶片相对含水量等各水分指标,降低了水分利用效率,减小了各种植模式间差异。"20+40"沟播在灌水135 mm条件下既保障产量又较等行距节水25%。由此表明,冬小麦"20+40"沟播可改善叶片水分状况,提高水分利用效率,增加作物产量。

| Abstract: | One approach to improve winter wheat yield and water use efficiency(WUE) is to identify appropriate crop planting pattern.The aims of this research were to compare planting pattern in wheat,evaluating yield and WUE.The experiment was carried out from October in 2008 to June in 2009 at Agronomy Experimental Station of Shandong Agricultural University.The winter wheat experiment consisted of 3 planting patterns and 3 irrigation schedules under the same plant population density(1.8 106 plant/hm2).Row spacing w... |
