Abstract: Three studies were conducted to look at the effects of tree age,felling system and number of reserved sprout on the sprout regeneration of Acacia auriculitormis in Qionghai county, Hainan Province.(1) Five plantations with the ages of 20,36, 48,60 and 72 months were cut at 60 cm stump height.Sprouting was most vigorous and consistent in young stands aging from 20 to 48 months. (2)Two felling systems(clear felling and felling with 50% trees removed)were involved in the coppicing experiment. There were no signifcant differences in stumps survival rate and number of coppice shoots produced per plant.(3)Comparison was made for the growth performance and biomass yield of three sprouting forests with 2,4 and all the sprouts per stump/plant reserved respectively. Results showed that the number of reserved sprouts had significant effects on the growth of diameter and height of 1.5 years old sprouting forests,but not on that of 4.5 years old.To maximize the biomass production,a thinning to the sprouts at about 6 months after cutting with 4 reserved sprouts per stump/plant is recommended.
