| 摘 要： | 在盆栽试验的基础上，构建了水分影响小麦光合物质生产的模拟模型。模型认为，土壤水分通过影响比叶面积而影响叶面积指数的变化，继而间接影响光合物质生产，经统计分析，不同生育阶段的叶面积指数与土壤水分有着极显著的相关性，进而对小麦群体光合作用的影响也十分明显。通过对该模型模型进行检验，比较其模拟值与实测值的拟合程度，发现模拟结果与实际结果比较一致。

| Abstract: | A simulation medel of winter wheat has been established based on the data from pot experiments ddring 1995-1996 and 1996-1997. The model described the water effect on biomass productbo of winter wheat. In this medel, it is thought that soi1 water influences LAI through special leaf area and LAI takes effect on biornass preduction directly. The medel was validated by the measured data from experiment and the results showed that the model is generally robust through a series of data to run the ndel. The mthel needs to be improved in the movernent of soil water and must be tested by a large number of field crop data. |
