摘要
以福建省岩溪林场2002年营造的马占相思家系试验林为对象,在2005年、2006年和2007年调查了马占相思22个家系的树高、胸径和冠幅,以筛选优良家系。结果表明:家系1号、2号、6号、9号、12号生长较快,其树高较高,胸径较大,是速生能力较强的优良家系,为营林提供可行性依据。
Tree height,diameter at breast height and crown width of 22 Acacia mangium families were investigated during 2005-2007.Statistical analysis of survey data showed that family 1,2,6,9,and 12 grew faster,whose tree height was higher and diameter at breast height was larger,were the fast-growing ability strong superior families and provided the feasible basis for the afforestation.
