| 摘 要： | 通过不同宽窄行栽培对玉米的产量动态进行分析。结果表明：宽窄行栽培有效改善了玉米的群体结构，改善了冠层的微环境，增加了中部冠层的透光率，促进个体生长发育，增加其LAI和干物质积累。宽窄行种植方式增加穗位叶的初始量子效率，使叶片能有效地利用弱光，改善玉米叶片的光合性能，最终提高玉米产量。

| Abstract: | A field experiment was conducted to analyze the dynamics of maize yield under the different wide and narrow row cultivations. The results indicated that the population structure was improved effectively under wide and narrow row cultivation, and the micro-environment of canopy was improved, the central canopy of light transmission rate was increased, the competition among individuals were less, the growth of individuals were better, dry matter accumulation and LAI was increased. This form improved the initial quantum efficiency of ear leaf, to impel the leaves get the effective utilization on weak light, and improved the photosynthetic performance of maize leaves, thus make the yield of maize was improved. |
