摘要: 在实验测定的基础上,分析了水稻叶片几何形态随逐日生长时间动态变化的规律,分别构建了叶长变化模型、叶长与叶宽关系模型、茎叶夹角变化模型、以及不同叶位最终叶长模型和叶片出叶时间模型。结合水稻叶片的三维形态模型,在计算机上编程实现了水稻叶片器官形态逐日动态生长变化过程的可视化模拟,具有较强的真实感,为构建虚拟水稻生长系统奠定了基础。

Abstract: Based on experimental observations,analyze the dynamics changes law about the diurnal variation of rice leaf geometry.Respectively,construct the model of the leaf length model,the relationship model of the leaf width and leaf length,and the model of stem and leaf angle.Build the relationship model of the final leaf length and leaf position,and establish the model of the leaf-emergence time and different leaf positions.In this study,realize the visual simulation of rice leaf with day-to-day dynamic growth on the computer,and has a stronger realistic effect,combined with the rice leaf 3D model.In order to build a virtual rice growth system lay the foundation.
