ABSTRACT: By means of systematic demonstration, this study found the mathematical relationship among several temperature driven nonlinear models for crop growth, and amended the limitation of the past nonlinear model in biological usage and the improved model with more general definition. Integrated with four years' field experimental data and Gauss function based temperature effectiveness model submitted in this study, the phenological development model for potato crop was established under different ecological conditions. The phenological development model explained the digital contribution of soil temperature increment on potato growth, and verified by the experimental data from different years and different conditions. There were strict co-relationships between modeling data and experimental data.
