摘　　要：分析了不同库/源比条件下单位叶面积负荷量对不同品种大豆结荚后干物质生产与运转的影响,结果表明:随着单位叶面积负荷量的增加,单位叶面积有效生产量随之增加,叶片光合生产潜力可以进一步发挥,光合产物有效性提高;提高单位叶面积负荷量对库源比大的品种产量的影响更大;在适宜叶面积指数基础上,通过增加单位叶面积负担粒数提高籽粒重是实现高产的关键。By analysing the relation of unit-leaf-area load to the production and distribution of dry matter after podding in different sink/source and varieties of soybean, it was clear that the photosynthetic potential could be fully played and the effectiveness of photosynthetic could be raised with the increase of unit-leaf-area load, which resulted in the rising of effective production per unit leaf area.
