峨眉山的重楼属种类分布及一些种年生长特性

Studies on Distribution of Paris and Annual Growing Characters of Some Species on Mountain E’mei

峨眉山的重楼属Paris调查研究结果为 :1 计有 8种 3变种 ,大多分布在海拔 10 0 0～ 14 0 0m的常绿阔叶林、竹林或灌木林下 ,喜湿润荫蔽及中性或微酸性肥沃土壤 ;2 只有巴山重楼Parisbashanensis分布的海拔较高 ,常在 180 0～ 2 80 0m范围 ;3 移栽于峨眉山下的 2种 1变种 ,与栽植于昆明的相比 ,其地上部物候期滞后 ,生长期也较短 ;4 凡用完整或带顶芽的根茎繁殖 ,成活率高且生长快。

The research of distribution and habitat of Paris on Mountain E’mei showed that:(1)there were 8 species and 3 varieties of Paris on Mt. E’mei, most of them distributed from alti. 1000m to 1400m in humid and fertile, neutral or acid soil under the evergreen broad leaved forests, bamboo forests and shrub forests. (2)only Paris bashanensis distributed at higher altitude about 1800～2800 m; (3)the growing time of P. polyphylla var. chinensis and other two species planted at the lower E’mei mountain area, was later and shorter than those plantd at Kunming; (4)the whole rhizome or with terminal bud as the planting material had a high survival rate and grew fast.
