辽西半干旱区浅埋式滴灌对春玉米耗水特性及产量的影响OACSCDCSTPCD
Effect of shallow-buried drip irrigation on water consumption characteristics and yield of spring maize in semi-arid region of western Liaoning
通过在辽西半干旱区开展遮雨棚微区控制灌溉试验,分析了浅埋式滴灌不同灌溉定额对春玉米耗水特性、籽粒产量及水分利用效率的影响.结果表明:浅埋式滴灌玉米生育期耗水量呈波动变化趋势,在拔节-抽穗和灌浆-收获期阶段耗水量较大,阶段耗水强度较大值出现在拔节-抽穗和抽穗-灌浆期;随着灌溉定额的增加,不同处理间籽粒产量显著提高,产量构成要素中百粒重和穗粒数的显著增加是籽粒产量提高的主要原因;与常规沟灌对照相比,浅埋式滴灌灌溉定额为2908.0 m3·hm-2时,…查看全部>>
A micro-plot field experiment with automatic rain shelter was carried out to study the effect of irrigation quota on water consumption characteristics,grain yield and water use efficiency (WUE) of maize by shallow-buried drip irrigation (SDI) in a semi-arid region of western Liaoning.The results showed that the water consumption of maize under SDI displayed a fluctuating trend during the whole growth period.The water consumption was larger during the jointin…查看全部>>
