英文摘要	In order to precisely manage tomato cultivation and to provide decision-making assistant for tomato production, a simulation model for tomato plant development stages in Chinese solar greenhouse was proposed based on scales of physiological development time(PDT). In this paper, the daily relative thermal effectiveness(RTE) determined the daily physiological development effectiveness (PDE), which accumulated to be daily physiological development time (PDT). The simulation model was validated by 4 growth experiments in different seasons in same greenhouse from 2003 to 2005. Validation of the model with data sets from different experiments showed a high goodness of fit between the simulated results and observed values, with RMSE of 1.0 to 1.6 days for different development stages including the start and duration of cotyledon germinating, plant seedling, plant flowering, tomato fruit setting and fruit ripe stage. Whereas the prediction accuracy of simulation model based on efficiency accumulate temperature (EAT) had much more error between the simulated results and observed values, with RMSE of 2. 1 to 12.0 days for different development stages. So the precision of development stages prevention by simulation model based on PDT is much higher than which by EAT.
