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。通过对该模拟模型进行检验，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。
Based on the pot experiment, a simulation model of water production affecting photosynthetic substances in wheat was constructed. According to the model, soil moisture affected leaf area index by affecting specific leaf area, which indirectly affected the production of photosynthetic material. According to the statistical analysis, the leaf area index at different growth stages had a significant correlation with soil moisture, The effect of photosynthesis is also very obvious. By testing the simulation model and comparing the fitting degree between the simulated value and the measured value, it is found that the simulation result is in good agreement with the actual result.
