In this paper, the cultivation pattern response mechanism on the growth, stem-shape, biomass and its allocation pattern of Taxus chinensis var. mairei plantation were explored, which provided theoretical basis for the Taxus chinensis var. mairei plantation cultivation in forest system and then the 12 year old T. chinensis var. mairei stands growth, stem-shape, biomass accumulation and biomass allocation of the interplantation in forest and the pure forest cultivation patterns were investigated in Mingxi County of Fujian Province. There were significant influence on the tree height and DBH, crown width, volume, the ratio of height to diameter and biomass of T.chinensis var. mairei plantation with different cultivation Patterns. The interplantation in forest can significantly promote the growth, improve the stem form quality, which was conducive to the accumulation of component biomass and total biomass; The order of biomass allocation of T. chinensis var. mairei plantation were stem > branch > leaf with different cultivation patterns; There were significant influence on biomass allocation ratio and component biomass ratio with different cultivation patterns, the interplantation in forest can significantly promote biomass allocation ratio of branches, leaves and stem, reduced root biomass allocation ratio; More biomass was allocated to aboveground part, stem, and leaves in the interplantation in forest pattern. The interplantation in forest pattern can promote T. chinensis var. mairei plantation biomass accumulation and effective allocation than that of pure forest cultivation pattern.
