摘要
对南方红豆杉(Taxus chinensis var.mairei)人工林和天然林进行树木解析,研究南方红豆杉人工林与天然林林分中的树干生长规律。结果表明,南方红豆杉人工林早期树高生长速度快,胸径增长量大,易于成林;人工林材积的增长量明显,并随树龄的增加呈现规律的递增趋势。南方红豆杉可做为珍贵用材推广栽培。
The experiment was carried out to investigate the growth rhythm of tree trunk by trunk analysis between natural forest and man-made forest of Taxus chinensis vat. mairei. Results showed that man-made forest of Taxus chinensis var. mairei was easy to form the forest with tree height growing rapidly in the preliminary stage, and big diameter at breast height growth. Natural forest volume significantly increased, and presenting regular increasing trend with the increase of tree age. Thus, iTaxus chinensis var. rnairei could be used as a precious timber forest to promote the cultivation.
