Design and Implementation of 3-Dimension Visualization System of Primary Wheat Diseases

On the basis of understanding and grasping the occurrence condition, popularity season, key impact factors for main wheat diseases of stripe rust, head blight and powdery mildew from research material and literature, 3D visualization model system for wheat growth, development and yield formation, which got wheat growth dynamic data from simulation model with a day as time step, was implemented. The occurrence discipline and evolution model of these diseases was designed. The model system could not only help the user understand the principle of wheat growth and diseases occurrence better, but also express the process of growth, development and disease evolution obviously and intuitively. The diseases diagnosis and visualization give decision-maker favorable suggestion on diseases prevention, and will help farmer, technician and decision-maker to use crop growth simulation model better and provide decision-making support. Now the visualization model for primary wheat diseases is in the process of development.
