不同种源南方红豆杉苗期与造林初期生长差异的比较研究

摘要

In this paper a comparative study was made on the growth differences of Taxus chinensis var. mairei from 4 provenances at the seedling stage and early plantation period in order to select the fine varieties suitable for large-area afforestation in the southern mountainous area of Anhui Province. The results were as follows: 1. The growth of the seedlings on the seedbeds from the provenance of Mingxi in Fujian Province was better than that from Jingde in Anhui Province, and the growth of the young plantations in mountainous areas from the provenances of Jingde County in Anhui and Shaoyang in Henan was better than that from the provenances of Mingxi in Fujian and Jiujiang in Jiangxi. 2. The height growth and basal diameter growth of the seedlings from the southern provenances with similar or higher altitudes and from local provenances were bigger and suitable for local afforestation.%为了选择能够适于安徽南部山区大面积栽植的南方红豆杉良种，本文对4个种源南方红豆杉幼苗、幼树生长差异进行了比较研究，结果表明：（1）福建明溪种源在苗床上苗木的生长优于安徽旌德种源，安徽旌德和湖南邵阳种源的山地造林苗木生长状况优于福建明溪和江西九江种源；（2）来源于海拔相似或较高处的南方种源和当地种源的苗高、地径生长量较大，适于当地造林。
