摘要
研究建立了不同土壤水分处理冬小麦同化物生产与积累模型 ,该模型综合考虑了环境因子对冬小麦物质生产能力的影响作用 ,引用简单的经验物质分配模式 ,得到同化产物的积累模型。并对模拟结果进行平均根方差分析 ,不同土壤水分处理叶、茎、穗干物质量模拟的平均根方差介于 1 5～ 1 0 0间 。
The paper introduces a canopy photosynthesis and a dry matter accumulation model of winter wheat. The model mainly considers the influence of the environmental factors on crop photosynthetic process, quotes the simple empirical partitioning pattern and establishes a dry matter accumulation model. The results of modeling are compared well with the experimental results through the statistical analysis by RMSE whose values range from 15 to 100. It indicates that the model has a good function to simulate the photosynthesis and the dry matter accumulation in winter wheat under water stress conditions.
