水稻群体干物质生产和产量形成的仿真研究

Study on Simulation of Dry Matter Production and Yield Formation in Rice Population

在模型Ｌ１Ｄ和ＪＰＲＩＣＥ的基础上，利用田间试验和文献资料，组建了水稻群体干物质生产和产量形成的仿真模型。验证结果显示，模型运行后干物质重、经济产量的仿真值与实测值基本一致，表明该模型能较好地反映水稻群体干物质生产和产量形成的动态变化，对生产实践具有一定的指导意义。

Based on L1D and JPRICE models, a simulation model for dry matter production and yield formation in rice population was established by incooperating field experiment results and literature references. The validation indicated that the simulated values of dry matter weight and economic yield coincided with the observed values, showing that the model could unfold the dynamics of dry matter production and yield formation in rice population and that it is of significance in guiding the production practices.
