摘要
在综合前人研究成果的基础上,兼顾模型的机理性与实用性平衡,构建了花生光合生产与干物质积累的模拟模型。模型采用高斯积分法有效地计算了冠层每日的总光合量,且充分考虑了环境因子中温度和CO2对光合作用的影响。利用试验资料对模型核实的结果显示,模型可以较好地预测不同生长条件下的生物量积累动态,具有较强的机理性和实用性。
Based on the existing models and published research results, considering the balance between explanation and application, a simulation model for Arachis hypogaea ( L. ) photosynthesis and dry matter production was established. In the model, Gauss integration method was adopted to effectively calculate daily canopy photosynthesis which sufficiently included the effects of temperature and CO2 on photosynthesis. The vali- dation of the model using data sets showed that the model could well predict the accumulation dynamic of biomass under diverse environments with good explanation and application.
