Abstract: Leaflitter of 6-year-old，12-year-old，20-year-old and 28-yea-old rubber plantations was used to studied the decomposition progress in one year under different control measures by mesh bag method. The results as following: leaflitter in 007mm and 10mm mesh bags was in a same decomposition dynamic, which was increased first and then drop, and the litter residues rates at the end of year were 3684 % and 3209 %, respectively. Leaflitter decomposition rates not only by the position of the buried layer influence, but also with soil fertilityrelated. After 240d, litter residues of ground plane (0cm), comparison hole (0-30cm) and fertile hole (0-30cm) not included roots removed were 3209%, 740% and 3458%, respectively. Litter decomposition of rubber was reflected by soil fertility mainly focus on the late stage of decomposition. To 240d, residues of litter in comparison hole and fertile hole (the average value of the group of roots reserved and roots removed) were 846% and 3562%, respectively. The difference of litter decomposition rates of 6yearold，12yearold，20and 28yearold rubber plantations were little at early stage but significant at late stage. To 240d, residues of litter were 294%, 705%, 1462% and 218%, respectively. Although rubber roots promoted litter decomposition at early stage, and convert to inhibition at the late stage, no significant influence was detected about rubber roots on litter decomposition at all stages.
