| 摘 要： | 对淯江河岸缓冲带硬头黄竹人工林生物量以及5种营养元素含量的分配格局进行了研究。结果表明:淯江河岸缓冲带硬头黄竹人工林单位面积的总生物量为98 672.01 kg/hm2,其竹株各器官生物量所占的比例分别为秆78.76%、枝7.37%、叶5.05%、根1.49%、蔸7.33%。其竹株各器官的5种营养元素含量均不相同,以代谢旺盛的竹叶含量最高。5种营养元素总含量在硬头黄竹竹株各器官中由大到小排序依次为叶42.62g/kg、蔸26.92g/kg、根24.99 g/kg、枝22.75 g/kg、秆21.83 g/kg。该竹林单位面积N、P、K、Ca、Mg 5种营养元素贮存总量为2 323.2 kg/hm2,其中K的贮存量最高为908.0 kg/hm2占39.1%,其次N为864.6 g/hm2占37.2%,Ca、P和Mg的贮存量仅占其总量的20%左右。
