我国棕榈藤栽培区区划初探

Study on the Division of Rattan Cultivation Area in China

本文依据华南和西南11个省(区)有棕榈藤天然分布的区域确定区划范围,选择与棕榈藤生态、生物学特性和生长规律密切相关的6个气象指标共60个气象台站的气候资料,应用聚类分析方法进行气候预分区。在此基础上,根据棕榈藤综合研究成果和生产实践经验,以黄藤、白藤、单叶省藤和异株藤等具有发展潜力的藤种及其适生条件作为主要区划依据,进行栽培区区划,将我国宜藤区划分为四个栽培区,即最适栽培区、适宜栽培区、次适宜栽培区和局部可植区。而后,提出各区适宜的栽培藤种及关键栽培技术。

According to the rattan distribution region, the division region is delimited. On the basis of the results of principal component analysis and clustering analysis on six climatic factors which are closely related to the growth and ecological characters of rattans, the climatic region of rattan cultivation have been divided. Then, in accordance with the achievement of comprehensive rattan research and experience of rattan cultivation, together with the cultivation requirements of main commercial rattan species, the whole region suitable for rattan planting in the south of china is divided into four divisions, and suitable commercial rattan species as well as their planting technique for each division are presented in this paper.
