摘　　要：本研究系统解析和改进了前人关于作物生长温度效应的非线性模型 ,并对修改后的模型进行了解释 .结合 4年的田间试验数据和本研究提出的基于高斯方程的作物生长温度效应模型 ,建立了不同生态条件下马铃薯生育期进程的模拟模型 .模型解析了地膜覆盖条件下土壤温度增加对马铃薯生育期进程的数值贡献 ,模拟了不同生态条件下马铃薯的生育期进展 ,结果表明模拟值与实测值具有良好的一致性 .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.
