摘要
对武陵毛竹竹株生长规律进行研究,结果表明,其经济用材长与竹径相关密切,直径越大,材长越长;枝下高与自然用材长也有密切关系。武陵毛竹有筒溥,轮枝少,营养区小,枝下高小的特点,所以主杆利用率相对较低;单株叶总面积比湘南等地略小,故光合效率低;竹杆纤维化程度较高;叶面积与竹重之比为4.24cm2/kg。还对竹杆利用率。
The growth regularities of moso bamboo, Phyllostachys pubescens ,in Wuling region was studied. Results indicated that the economic culm length of the bamboo was positively related to its diameter in breast height.
