摘要
给出了水肥适宜状况下冬小麦叶片光合作用理论模式 ,模式包含了光、温因子以及CO2 浓度对叶片光合速率的影响。由于综合模式参数过多难以直接求解 ,作者给出了模式参数的简易求解方法。最后 ,利用Licor-6 2 0 0光合作用测定系统对鲁麦 2 2号冬小麦叶片光合速率进行测定 ,在此基础上建立起水肥适宜状况下的冬小麦叶片光合作用模型 ,为进一步建立更加准确的农业气候资源数值模式提供了前提条件。
A comprehensive model for simulating leaf photosynthesis of winter wheat was established, and the impacts of radiation, CO 2 concentration and temperature on the photosynthesis were fully considered in the model. Since there are too many factors in the model, which made it difficult to calculate the parameters directly, a simple method was put forward to find out the parameters easily. According to the simple method, the leaf photosynthesis model for winter wheat Lu-Mai 22 was established based on a set of data observed with Licor-6200 photosynthesis analyzer, and the results of the model accorded well with the observed value of experiment. The model will provide some theoretical basis for improving the crop models to simulate winter wheat growth in HuangHuaiHai Region
