Abstract：The simulation of cucumber growth stages is necessary for studying its growth in relation to environment. To explain the relationship of temperature and growth rate of each stage, the exponential sine equation has been derived. The parameters of the model in different stages were confirmed by 3 groups of data about cucumber growth stages from 2006 to 2007, while the data in 2008 was used to check the model. Finally, the model was compared with the results of the growing degree days. The result shows that the starting time and days of each development period are simulated well by exponential sine equation. Compared with the growing degree days, the forecast precision of exponential sine equation precedes.
