摘  要：
在福建省明溪县进行观赏型南方红豆杉重塑技术试验。结果表明:截干能够促进南方红豆杉地径生长,能够抑制植株高度及高生长,留干长度越短、缩剪程度越重其植株高度及高生长越小。截干不能影响植株冠幅,但缩剪强度能够显著抑制冠幅生长。截干可以促进南方红豆杉干上潜伏芽的萌发,且留干较长的萌蘖数量较多。截干能够促进新枝萌发,且留干较短且强度缩剪对新枝萌发数量有促进作用。截干对直立型、平展型新枝分化无明显影响,但留干长度较短且强度缩剪可以显著增加直立型新枝比例,减少平展型新枝比例。截干与否、截干高度以及缩剪强度对叶片色泽不存在明显作用。截干可提高植株的枝叶浓密度,留干较短且强度缩剪可进一步促进枝叶浓密。

摘  要：
The reshaping trial of Landscape type Taxus chinensis var. mairei was conducted in Fujian Mingxi. The results show that the stem cutting-off can promote ground diameter growth of Taxus chinensis , inhibit plant height and high growth. The shorter length of remain stem, the smaller the plant height and high growth. The stem cutting-off can not affect the plant canopy, but shrink shear strength can significantly inhibit crown growth. The stem cutting -off can promote latent buds germination of Taxus chinensis, and longer remained stem got more buds. The stem cutting-off can promote the new branches germination; the shorter remained stem and high strength shrink shear could increase the number of new branches germination. The stem cutting-off had no significant effect on upright, flat new branches differentiation. However, shorter length of remain stem and high shear strength can significantly increase the proportion of upright new branches, reduce the proportion of the flat type of new branches. The stem cutting-off or not, the remaining stem height and shrink shear strength have no significant effect on leaf color. The stem cutting-off can increase the leaves and branches. Shorter remaining stem and high strength shear can further promote the dense of leaves and branches.
