摘　　要：通过改变大豆源库比例,分析了大豆不同品种在不同库/源比条件对大豆叶片光合速率及结荚后同化物质生产、运转与分配的影响,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进一步发挥,光合产物有效性提高,同时提高单位叶面积负荷量对库源比大的品种产量影响更大。By analyses the relation of Source and Sink Manipulation 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.
