毛竹(Phyllostachy pubescens)是我国南方重要的森林资源,它不仅在我国竹产业发展中占有重要的地位,而且在固碳增汇中起着更为重要的作用.本研究以湖南桃江县不同年龄毛竹人工林为研究对象,探讨不同年龄毛竹林各器官碳含量分布特征.研究结果表明:毛竹林不同年龄竹林各器官碳素平均含量在389.334~534.051 g·kg-1之间,且器官不同,碳含量不同.1年生,3年生,5年生毛竹林地上部分各器官碳含量分别为:竹竿>竹叶>竹枝、竹枝>竹竿>竹叶、竹叶>竹竿>竹枝;地下部分各器官碳含量分别为:竹鞭>侧根>竹蔸>须根、竹鞭>竹蔸>须根>侧根、须根>竹蔸>竹鞭>侧根.但各龄级器官碳含量差异不显著(P>0.05),并随着毛竹年龄的增长,其器官碳含量无明显的变化规律.
Phyllostachy pubescens is an important forest resource in southern China, which not only plays an important role in the development of bamboo industry in our country, but plays an even more important role in carbon sequestration.In the present study, The results showed that the average carbon content of various organs of bamboo forests varied from 389.334 to 534.051 g · kg-1 in different age groups, with different organs and carbon The contents of carbon in organs of 1-year-old, 3-year-old and 5-year-old bamboo forests were respectively as follows: bamboo pole> bamboo leaf> bamboo branch> bamboo pole> bamboo pole> bamboo leaf> bamboo pole> bamboo pole> bamboo branch; Bamboo root> bamboo root> bamboo root> bamboo root> bamboo root> bamboo root> bamboo root> root root> bamboo root> bamboo root> bamboo root> bamboo root> bamboo root> bamboo root> bamboo root> With the growth of bamboo age, there is no obvious change rule of organ carbon content.
