摘　　要：作物光温反应特性是农业气象学重要的知识点,在指导花期调控方面具有很强的应用价值。鉴于传统的实验教学存在的诸多不足,将混合式学习理论应用于实践教学,基于杂交稻制种过程中的花期相遇和气象灾害问题,设计杂交稻制种播期预测虚拟仿真实验。该实验以Unity3D为开发平台,实现了水稻生长发育过程的虚拟展示,改变光温条件后可以直接观察到发育速度的变化,输入不同的父母本播种期后可以显示制种结果的差异性。实验结果表明,通过人机交互不仅加深了学生对光温反应特性的理解,更提高了学生的系统分析和综合设计能力。The characteristic of photo⁃thermo reaction of the crop is an important knowledge point in agricultural meteorology,which has a high application value in florescence control.In view of the fact that the traditional experimental teaching has many shortcomings,the blended learning theory is applied to practice teaching.The virtual simulation experiment for prediction of the sowing time for hybrid rice seed production was written on the basis of florescence synchronization and meteorological disasters in the seed production process of hybrid rice.In this experiment,the Unity3D is used as the development platform to realize the virtual display of growth and development process of the rice.Students can directly observe the change of growth speed after changing the photo⁃thermo conditions.The difference of seed production results can be displayed after inputting different sowing time of rice male and female parents.The experimental results show that,with the human⁃computer interaction,students′understanding of the characteristics of photo⁃thermo reaction is deepened,and students′abilities of system analysis and comprehensive design are improved.
