This technology, focusing on the soybean variety 'Hualien No. 1,' utilizes multi-year organic cultivation trials and environmental monitoring data to develop a growth prediction model. This model accurately forecasts crop development stages, with prediction errors of only about 3 days for the flowering stage and 7 days for the maturity stage. By analyzing two key factors—temperature and light intensity—it provides dynamic growth prediction results. The system also combines field management recommendations and risk assessment indicators to help farmers optimize operational schedules and resource allocation, thereby effectively improving management efficiency and reducing production risks.
