Abstract：To ensure the balance of product supply,predicting the crop growth period is crucial for the rational arrange-ment of variety selcection and planting period in agricultural production.For newly developed processing tomato planting bases,a growth period simulation model based on effective accumulated temperature was constructed,based on the tem-perature response characteristics of processing tomato development..The model was tested using experimental data from different varieties,planting periods,and ecological regions.The results showed that the absolute simulation error of the constructed model for most growth stages was concentrated in 0-6 days,with a root mean square deviation less than 4 days and a normalized root mean square error less than 15％.In the three development stages from bud emergence to flow-ering,fruit setting to fruit development,and fruit development to red ripening,the model showed high simulation accuracy and small errors.The coefficient of determination(R2)for the entire growth period was 0.971 and 0.969,indicating that the constructed model has good predictive accuracy and broad applicability,providing strong technical support for variety layout and the rational arrangement of planting periods in agricultural production.
