Abstract: Taking annual Mesua ferrea and Erythrophleum fordii trees planted under 8 years old rubber forest as the observation object,four times of investigation were made on the tree height of two tree species in March,June,September and December. The results showed that the peak height growth of the two species appeared from June to September,and as for the largest amount of height growth,the average tree height growth of Mesua ferrea was 14.97 cm,and the average tree height growth of Erythrophleum fordii was 34.65 cm. In addition,the best cultivation model was found to be Mesua ferrea + Erythrophleum fordii + parashorea cathayensis.
