| 摘 要： | 以中晚熟品种郑单958和晚熟品种丹玉405为试验材料，采用裂区设计，在3种不同种植形式和3种不同密度条件下，对玉米品种与密度、品种与种植形式互作的关系进行比较分析。结果表明，郑单958在二比空种植形式60 000株/hm2下产量最大，为11 726.71 kg/hm2；丹玉405在二比空种植形式49 500株/hm2下产量最大，为11 092.03 kg/hm2。郑单958和丹玉405在各自产量最高时，百粒重、穗行数和行粒数均最大，两个品种在二比空种植形式下功能叶的叶面积指数和净光合速率较高。

| Abstract: | Using middle-late season variety Zhengdan958 and late variety Danyu405 as the experimental materials, experimental treatments applied in a split plot design with three planting patterns and three densities, the comparative analysis of the varieties, densities and planting patterns in maize was studied. The results showed that Zhengdan958 was the highest value of yield was 11 726.71 kg/ha using the 2-0 culture and the density at 60 000 plants/ha, Danyu405 was the highest value of yield was 11 092.03 kg/ha using the 2-0 culture and the density at 49 500 plants/ha. When the yield of the two varieties was the highest, respective, the hundred grain weight, ear row number and row grain number reached the maximum. And the leaf area index and net photosynthetic rate of functional leaves in 2-0 culture were higher than other planting pattern. |
