摘　　要：[目的]探讨不同行距配置与不同种植密度相配套对玉米产量的影响。[方法]以大穗型玉米单交种桂单901为供试品种进行田间试验,以4种行距配置为主处理,包括60 cm等行距单行单株、75 cm等行距单行单株、80 cm+40 cm宽窄双行单株、90 cm+40 cm宽窄双行单株;4种种植密度为副处理,包括45000、52500、60000、67500株/hm^2。[结果]不同行距配置及不同种植密度对玉米产量都有显著的作用效应,二者交互作用产生正效应,但提高产量的作用效应未达显著水平;宽窄双行单株优于等行距单行单株,是较优的行距配置选择。[结论]52500株/hm^2为最优种植密度,其次为密度60000株/hm^2,较适宜大穗型品种丰产栽培选择;行距最优配置为80 cm+40 cm,其次为90 cm+40 cm宽窄双行单株处理,产量可达8797.2~8689.5 kg/hm^2。[Objective]To explore the effect of different row spacing forms and different planting densities on corn yield.[Method]Guidan 901,a single cross maize variety with large panicle,was used as the test variety,and four row spacing configurations were used as the main treatment,including 60,75 cm,80 cm+40 cm,90 cm+40 cm.And the sub-treatments were 45000,52500,60000,67500 plants/hm^2[Result]Different row spacing forms and planting densities had significant effect on maize yield,and the interaction between them had positive effect,but the effect of increasing yield was not significant;narrow double row single plant is better than single plant with equal row spacing,which is a better choice of row spacing configuration.[Conclusion]The best planting density was 52500 plants/hm^2,followed with 60000 plants/hm^2,which was more suitable for the high-yield cultivation of large spike varieties;the best row spacing configuration was 80 cm+40 cm,followed by 90 cm+40 cm,the yield of which could reach 8797.2-8689.5 kg/hm^2.
