九连山国家自然保护区贵州石栎的生长过程研究

[目的]了解贵州石栎的生长过程以挖掘其开发利用潜力。[方法]对九连山国家自然保护区天然阔叶林中的3株贵州石栎和1株野生杉木进行树干解析。[结果]贵州石栎具有早期速生的特性,且超过该地野生杉木的长势,后期胸径生长潜力较大。[结论]选择贵州石栎造林地时,宜避开湿地、湿润等地下水位过高湿地,幼龄抚育间伐宜创造一定的荫蔽环境,中龄期及以后则需保持一定的采光条件,减少种植密度以缩短培育期。

Growth Process of Lithocarpus elizabethae in Jiangxi Jiulianshan Nature Reserve

[Objective] In order to study the growth course of Lithocarpus elizabethae to exploit and utilize its development potential.[Method] Three Lithocarpus elizabethae trees and one Cunninghamia lanceolata tree in the natural broad-leaved forest of Jiangxi Jiulianshan nature reserve were selected for stem analysis in this paper.[Result] Lithocarpus elizabethae had the characteristics of the early fast-growing,and more than wild-fir growing.At the late stage,the DBH growth potential was a litter larger.[Conclusion] If Lithocarpus elizabethae was selected for afforestation,it should avoid wetlands and other water table with high humid,create some shade environment during young tending,but aim to shorten the incubation period,it should be reduced the planting density,supplied the lighting conditions in middle-aged and after middle-aged.
