摘  要：
采用分层挖掘法对炎陵县毛金竹鞭系结构进行调查,结果表明:研究区样方内毛金竹林地下鞭段条数为80.7条/m2,总鞭长2 271.2 cm/m2,鞭质量为4 502.0 g/m2,平均鞭径为1.27 cm。0~10 cm土层的鞭段数、鞭长、鞭质量分别占整个竹鞭系统的77.3%、73.5%和73.0%。样方内总鞭芽数为1 028.7个/m2,其中弱芽、壮芽、笋芽、空芽、岔鞭分别占14.7%、25.9%、1.5%、53.6%和4.3%。2~3龄竹鞭上壮芽数量为210.3个/m2,占总壮芽数量的79.1%。毛金竹竹鞭无分岔鞭段数量占总鞭段数量的59.1%,一侧单岔鞭段数量占总鞭段数量的28.5%。

摘  要：
By the method of hierarchical mining,the bamboo rhizome system structure of Phyllostachys nigra var. henonis was researched in Yanling County. The results showed that the number of rhizomes was 80. 7 per square meter,the length of rhizomes was 2 271. 2 cm / m2,the weight of rhizomes was 4 502. 0 g/m2,the diameter of rhizomes was 1. 27 cm. The number,length,weight of rhizomes in 0 ~ 10 cm soil layer were 77. 3% 、73. 5% and 73. 0% of the total rhizome system respectively. The number of buds in quadrat was 1 028. 7 per square meter,the weak buds,strong buds,shoot buds,empty buds,branch whips were14. 7% 、25. 9% 、1. 5% 、53. 6% and 4. 3% of the total buds respectively. The number of strong buds in rhizome of 2 ~ 3 a were 210. 3 per square meter,79. 1% of total number of strong buds. The number of non- bifurcation rhizomes was 59. 1% of the total rhizomes and the number of single side single rhizomes was 28. 5% of the total rhizomes.
