摘要
讨论了植物的氮（Ｎ）素营养过程与Ｃ的消耗关系、光合作用与Ｎ投入的关系、水分平衡与植物的Ｎ素营养的关系．
Plants exhibit potential to compensate for imbalance in the availability of nitrogen. They achieve nitrogen acquisition by several ways. As N enters plant (absorption, translocation, assimilation), it costs considerable energy of plant, in which the carbon serves as energy source. In order to translocate N efficiently within plant and maximize growth, the relationship between nitrogen nutrition and the cost of C, photosynthesis, and water equilibrium were discussed.
