Abstract: A study was conducted in a split plot design with three replications to investigate the effects of stump height and stand density on the sprout regeneration of 3-year-old Acacia auriculijormis at Yangjiang, Qionghai County (110°30'E, 18°14'N) of Hainan Province. Results showed that both the stump height and stand density had statistically significant effects on the number of sprouts produced per stump, and diameter (50 cm above the point of origin) and biomass production of sprout forests 19 months after cutting. The percentage of stump sprouting, and survival rate of stumps and length of sprouts 19 months after cutting were significantly influenced by stump height but not stand density. To maximize the biomass production of sprout forests of A. auriculiformis,a. stump height of 60 cm is recommended.
