e0“a density of 67,500 plants/hm2 and 40 + 80 cm row spacing is the best combination, improving light energy utilization efficiency, delaying the leaf senescence process, and increasing the yield, which can provide a theoretical reference for the planting pattern of maize in Shanxi Province.”

- Association Maize leaf net photosynthetic rate decreased as planting density increased.
- Association Maize leaf transpiration rate increased as planting density increased.
- Intervention effect Excessively high or low density increased leaf MDA content.
- Intervention effect Excessively high or low density decreased leaf SOD and CAT activities.
- Intervention effect The 40 + 80 cm spacing improved light energy utilization efficiency.
- Intervention effect The 40 + 80 cm spacing slowed maize leaf aging.
- Intervention effect The 40 + 80 cm spacing promoted maize growth, development and yield.
- Association The interaction between the planting factors significantly affected corn yield.
