摘  要：
本研究通过了解南方红豆杉人工林生长、干形、生物量积累与分配格局的培育模式响应机制,为南方红豆杉人工林林下栽培体系提供理论基础。在福建明溪对林隙套种与纯林培育模式12年生南方红豆杉的生长、干形、生物量积累与分配进行调查。结果表明,培育模式对南方红豆杉树高、胸径、冠幅、单株材积、高径比和生物量有显著性影响,林隙套种显著促进南方红豆杉生长,改良干形品质,利于南方红豆杉构件生物量及总生物量积累;不同培育模式中南方红豆杉生物量分配比大小顺序均为干>枝>叶;培育模式对南方红豆杉生物量分配比与构件生物量比有着显著性影响,林隙套种南方红豆杉增加枝、叶、干等地上生物量分配比,降低根系生物量分配比;林隙套种的生物量更趋向地上部分、干和叶的分配;林隙套种较纯林培育模式促进南方红豆杉人工林生物量高效积累与有效分配。

摘  要：
In this paper,the cultivation pattern response mechanism of the growth,stem-shape,biomass andits allocation pattern of Taxus chinensis var.mairei plantation were explored,which provided a theoretical basisfor Taxus chinensis var.mairei plantation cultivation in forest system.12-year-old T.chinensis var.mairei stands growth,stem-shape,biomass accumulation and biomass allocation of the interplantation in forest gapsand the pure forest cultivation patterns were investigated in Mingxi County of Fujian Province.The resultsshowed that different cultivation patterns had significant influence on tree height and DBH,crown width,volume,the ratio of height to diameter and biomass of T.chinensis var.mairei plantation.The interplantation inforest gaps could significantly promote the growth and improve the stem form quality,which were conducive tothe accumulation of component biomass and total biomass.The order of biomass allocation of T.chinensis var.mairei plantation was stem>branch>leaf under different cultivation patterns.Different cultivation patternsalso had significant influence on biomass allocation ratio and component biomass ratio.The interplantation inforest gaps could significantly promote biomass allocation ratio of branches,leaves and stems,and reduce rootbiomass allocation ratio.More biomass was allocated to the aboveground part,stems and leaves in theinterplantation in forest pattern.The interplantation in forest gaps pattern could promote T.chinensis var.mairei plantation's biomass accumulation and effective allocation in comparing with that of pure forestcultivation pattern.
