种植密度和氮肥用量显著影响玉米产量和品质形成,优化施氮量和种植密度是玉米增产提质的重要技术途径,但在新疆南疆干旱区如何优化种植密度和氮肥管理尚缺少研究。为此,本试验于2024年通过设置4个种植密度(D9:9.0×10^(4)株∕hm^(2)...种植密度和氮肥用量显著影响玉米产量和品质形成,优化施氮量和种植密度是玉米增产提质的重要技术途径,但在新疆南疆干旱区如何优化种植密度和氮肥管理尚缺少研究。为此,本试验于2024年通过设置4个种植密度(D9:9.0×10^(4)株∕hm^(2),D12:1.2×10^(5)株∕hm^(2),D15:1.5×10^(5)株∕hm^(2)和D18:1.8×10^(5)株∕hm^(2))和4个施氮水平(N0:0 kg∕hm^(2),N180:180 kg N∕hm^(2),N270:270 kg N∕hm^(2)和N360:360 kg N∕hm^(2)),研究了种植密度和氮肥用量及其互作对玉米籽粒产量、籽粒品质、氮肥偏生产力(NPEP)和氮肥农学利用效率(NAE)的影响。结果表明,D15N270、D18N270、D15N360和D18N360表现出较高的玉米产量,且4个处理组合之间不存在显著性差异,较D9N0、D12N0、D15N0、D18N0、D9N180、D12N180、D15N180、D18N180、D9N270、D12N270、D9N360和D12N360处理组合分别增产3.8%~74.3%、2.4%~72.0%、10.5%~85.7%和9.4%~83.9%。D15N270较其他处理组合改善了玉米籽粒品质(蛋白、脂肪、淀粉含量)。增密提高了玉米氮肥利用效率,随着施氮量的增加氮肥偏生产力呈下降趋势,D15N270和D18N270处理下的氮肥农学利用效率高于其他处理组合。综合考虑,种植密度设为1.5×10^(5)株∕hm^(2)、施氮量设为270 kg∕hm^(2)左右是阿拉尔垦区提高玉米产量、品质及氮肥利用效率的有效管理方案。展开更多
