鼎湖山自然林豆科固氮植物资源的调查研究

A SURVEY on the Nitrogen-Fixing Legume Resources In the Dinghushan Natural Forests

本文在调查鼎湖山自然林木本豆科植物结瘤固氮的基础上,参阅了国内外有关豆科植物结瘤固氮的主要文献,研究了鼎湖山自然林木本豆科植物的固氮资源。结果得出鼎湖山自然林中常见的木本豆科植物共有41种,其中乔木15种,灌木6种,木质藤本20种;有结瘤固氮特性的26种,其中乔木11种,灌木5种,木质藤本10种;经初步调查未见根瘤的6种,其中乔木2种,灌木1种,木质藤本3种;未调查的9种,其中乔木2种,木质藤本7种。本研究结果为鼎湖山木本豆科固氮植物资源的保护、管理和开发利用提供了科学论据,在理论和应用方面均有重要意义。

Nitrogen-fixing woody legumes in the natural forests of Dinghushan were investigated. Forty one species of woody legumes, including 15 species of trees, 6 species of shrubs and 20 species of woody lianas, were found in the natural forests of Dinghushan. Of the 41 species reported from this survey and the references, 26 species including 11 species of trees, 5 species of shrubs and 10 species of woody lianas produced nodules and fixed nitrogen: 6 species including 2 species of trees. 1 species of shrub and 3 species of woody lianas did not nodulate: 9 species including 2 species of trees and 7 species of woody lianas were neither surveyed nor reported on their nodulating and nitrogen-fixing capabilities.The results obtained from this study are of very significance for the conservation. management and utilization of the nitrogen-fixing woody legume resources in Dinghushan.
