| 摘 要： | 试验以桂单162为供试材料，采用2因素裂区设计，密度为主处理，行距为副处理，研究4个种植密度下4种行距配置方式对玉米产量及其构成因素的影响。结果表明：密度、行距及密度与行距互作对玉米出籽率的影响不显著；密度、密度与行距互作对玉米结实长度影响达到极显著水平，随着密度加大结实长度越短，不同密度与不同行距配置才能对结实长度起到最大的影响作用；种植密度对穗粗影响达到显著水平，穗粗随着种植密度加大而变小；密度、行距及密度与行距互作对产量的影响达到极显著水平，4种种植行距下4000株/667m2产量最高，4个密度下60 cm 单行单株种植产量最高，桂单162以4500株/667m2，60 cm 单行单株种植产量最高。
