| 摘 要： | 通过几何模拟，从理论上分析了北半球夏半年不同行向水稻遮荫宽度在不同纬度、不同季节的日变化，结果表明：中、低纬度地区东西行向遮荫宽度较小，有利于群体充分利用光能，而高纬度地区则以南北行向有较大优势，此外，还讨论了行向、行距与光能利用的关系。 |
| 关 键 词： | 穗型 群体 微气象特性 太阳直接辐射 水稻 行向 遮荫宽度 光能利用 |

| Abstract: | The day changes of the sun-shading width in rice with different row directions in the areas of different latitudes and seasons during the summer half-year on northern hemisphere were calculated by using geometric model. The W-E row in the areas of low and middle latitudes and the N-S row in the areas of high latitudes showed a narrower sun-shading width and better sunlight utilization. |
| Keywords: | Rice Row direction Sun-shading width Sunlight utilization |
