Abstract: In order to study the relationship between the growth rules and the accumulated temperature of Phalaenopsis, paper disk method, correction factor calculation and linear regression analysis were applied to optimize the method of Phalaenopsis leaf area estimation, then the growth rate curve established was analyzed and fitted. Based on that, the relationship between the growth curve and the accumulated temperature of Phalaenopsis was analyzed. The result showed that the growth model between the leaf area (S) and the accumulated temperature (T) was a quadratic functional relationship, S=0.043T2 21.36T 215.60. The growth curves were appropriately fitted with the growth dynamic change during Phalaenopsis vegetative growth period. It is feasible to analyze and fit the growth curve of the Phalaenopsis using the growth models.
