| 摘 要： | 利用Licor-6200便携式光合作用测定仪，对1949年以来不同历史年代的冬小麦叶片光合作用进行了大量测定，拟合了不同年代12个典型品种的叶片光合作用光响应曲线，首次揭示了黄淮海地区冬小麦叶片光合特征参数随时间演变规律，并利用数值模式分析了特征参数对光合日总量的影响。该研究为我国气候生态数值模型提供了基础数据，并为模式的区域应用提供了重要前提条件。

| Abstract: | A series of winter wheat varieties in different decades is selected for measuring the leaf photosynthesis under suitable soil moisture and temperature conditions. The light response curves are fitted for each variety, and the initial quantum efficiency, maximum photosynthesis rate and respiration rate are determined. The variation regularity of leaf photosynthesis parameters with time is revealed based on these characteristic parameters. Numerical analysis of the effects of the initial quantum efficiency and maximum photosynthesis rate on the daily photosynthesis shows that it is not suitable to quote parameters from foreign literatures as the basic parameters in the Chinese crop models. A set of basic parameters of the crop model is presented, which provides premise for simulating the regional application with crop models in the future. |
