为了明确玉米高产的最佳种植模式，采用完全随机区组田间试验设计，设不同种植密度的7个玉米种植模式处理（等行距单株播种、等行距双株播种、等行距双株播种、宽窄行双株播种、宽窄行双株播种、宽窄行双株播种、宽窄行双株播种），研究了不同种植模式对玉米群体光合性能、干物质积累和产量形成的影响。结果表明：宽窄行双株栽培模式不仅能够改善玉米的群体结构，还减少了株间竞争，促进了个体生长发育，使得玉米群体保持了较高的叶面积指数和光合效率，干物质积累量和产量均最大，增产效果显著。玉米最优种植模式为宽窄行双株播种，在宽行70 cm、窄行40 cm、穴距40 cm、种植密度90750株/hm2条件下，玉米产量为11536.35 kg/hm2。

To clarify the best planting mode , using completely randomized block design in the field , with different planting density of 7 planting modes of maize, the effects of different planting modes on photosynthetic performance of maize populations, dry matter accumulation and yield were studied.The results indicated that the population structure of maize was improved , inter plant competition was reduced , individual growth and development was promoted, the leaf area index and photosynthetic efficiency were higher, the dry matter accumulation and yield were the maximum, and the yield increasing effect was obvious under the planting mode of wide and narrow row double planting, the wide row was 70 cm, the narrow row was 40 cm, the hill spacing was 40 cm, the planting density was 90 750 plant/hm2 , it was the optimal planting pattern for maize , in which the yield could reach 11 536.35 kg/hm2.
