中文摘要：

通过对番茄不同发育阶段与环境因子关系的分析，建立了番茄生长发育的非线性动态模拟模型，利用试验数据对模型进行了检验。结果表明，对不同发育阶段模拟，绝对误差均为1～2d，对全发育期模拟，绝对误差均在4d之内;平均相对误差小于4％。

英文摘要：

Following the idea of ＂former researcher＂, a model to simulate tomato growth was established in this study. The model was focused on the influence of temperature and daylength on the tomato development. The data used to determine the model parameters came from field experiments conducted in Beijing in 2003 to 2004. Model validation against the data from independent measurements and the field surveys showed that the standard errors ,comparing the simulated values with the observed values, were within 2 days for the different development period and within 4 days for entire development period. The results also showed that average relative error was less than 4 %.
