Construction and implementation of model-based visual rice growth system

Driven by weather, soil, variety and cultivation techniques databases and integrating process-based growth simulation model, morphogenesis model, visualization model, strategy analysis and estimate model, weather data generation model and variety parameter debug model, a model-based visual growth system in rice (MVGSR) was developed using component-based software and visualization technology. The system was programmed in the .NET framework with the C# language, and the OpenGL library was used for realizing 2D and 3D graphics application and visualization. The implemented system could be used for predicting growth progress and visualizing morphological architecture of rice plant under various environments, genotypes and management strategies, and had the functions as data management, growth simulation, strategy evaluation, real-time prediction, temporal and spatial analysis and system help. The MVGSR should be useful for improving the levels of digitalization and visualization of crop growth and production system and lay a foundation for development of visual agriculture.
