摘　　要：为挖掘玉米的增产潜力,以常规种植为对照,进行玉米株间疏密种植试验。试验结果表明,株间疏密种植模式能明显提高玉米植株的光合速度和气孔导度,同时玉米的单穗粒质量、百粒质量和产量也有显著提高。In order to tap the potential of increasing maize yields, an experiment of maize spacing plantation was conducted with the regular plantation as the control group. The experiment results show that maize spacing plantation can remarkably improve maize photo synthesis rate and stomatal conductance, and there is a strong increase in maize single kernel quality, hundred kernel quality, and thousand kernel quality as well.
