Abstract
The above-ground biomass and component factors of Oligostachyum lubricum were investigated and the above-ground biomass allocation and its relationship with ramet component were analyzed.The results indicated that present above-ground biomass allocation pattern of 1-year-old stands was stem﹥foliage﹥twig and that of 2-year-old stands was foliage﹥stem﹥twig.The rate of stem biomass of 2-year-old stands was extremely lower while that of foliage biomass of 2-year-old stands was extremely higher respectively than that of 1-year-old stands.However,there was no significant difference in twig biomass between 1-and 2-year-old stands.There were significant or very significant correlation between component factors and component biomass of 2-year-old stands.The total height(TH),height under branch(HB) and round of branches(RB) were subordinate factors of the diameter at breast-height(DBH) of 2-year-old stands.DBH of stands had decisive effects on the biomass of each component and above-ground part of stands and the relationship between them followed very significantly a cubic function.Increasing in allocation proportion of foliage biomass was beneficial to develop new habitat and consolidate present habitat for O.lubricum.
