摘　　要：禾本科作物开花后是产量形成的最主要时期.水稻抽穗至成熟期的物质积累量占产量的50％～90％,开花后叶片量和质动态变化在很大程度上又决定于开花后氮素的吸收和分配.花后氮素的吸收与运转还与氮素的生理效率密切相关.作物生长模拟技术在描述作物生长发育和生理生态动态过程和作物管理决策方面取得显著的成效.该研究就作物花后氮素吸收与分配的生理生态、氮素吸收与分配的动态模拟以及开花后氮素吸收、转移与籽粒蛋白质含量遥感监测的关系等方面的研究进行了综述.Grain filling in crops is the most important period of yield formation, the accumulation of matter accounted for 50% to 90% from heading to maturation period in rice. The dynamic change on the quantity and quality of leaves after flowering is determined by nitrogen uptake and translocation to a great extent. Nitrogen uptake and translation is also closely related to nitrogen physiological efficiency. The research pro- gress of nitrogen uptake and translocation during grain filling and the dynamic simulation of nitrogen absorption and distribution were summa- rized.
