摘要
根据苏柳172,194无性系在江苏洪泽、泗洪,山东泰安、平阴,浙江富阳等地5~11年生试验林调查材料,对两无性系的生长规律、径阶结构、干形变化和材积方程的选用以及林分成熟进行了研究。结果表明,两无性系均具有明显的早期速生特性,7年生的相对直径分布范围分别是0.532~1.216和0.584~1.362;平均f0.1为0.443和0.444;用作中小径级矿柱林的采伐年龄应在6~10年。
The accretion,diameter class
contribution,variation of trunk form,selection and application of standing volume equa-tion and
stand maturdtion were studied,bassed on the investigating data of 5-11 years old CL’J-
172'and CL' J- 194' plantation in Hongze and Sihong county of Jiangsu province,Taian of
Shandong and Fuyang of Zhejiang province. Theresults showed that they were early
fast-growing and the relative diameter distribution of 7 years CL' J- 172' plantationwas from
0.532 to 1. 216,the one of CL'J-194' was from 0.584 to 1.362.The mean of CL' J-172' was 0.443
andthat of CL'J-194' was 0.444.The stands about 6-10 years could be cut over for pit wood.
