Abstract:

Considering effects between the growth of crop and greenhouse environment，a greenhouse simulation model was developed based on the principle of greenhouse energy and mass balances，including temperature model and humidity model，the simulation results were validated by experiment.The results showed that the simulated values agreed well with the measured ones.The determination coefficient (R2) and squared error (RMSE) between the simulated and the measured value for the simulated values of temperature and humidity were 0.9861，0.803 and 0.8，3.727，respectively.Based on the results obtained in this study，it could be concluded that the model developed could give a satisfactory prediction of temperature and humidity，the model developed in this study could provide theoretical basis for the optimization of the greenhouse environment.
