摘要
对广西黄冕林场7年生47个黑荆树子代林的生长指标进行测定,以栲胶和木材两用型为目的经营黑荆树人工林,综合家系的单宁产量指标和材积生长指标,划分出优先选择家系类型(优选型)、有待优选家系类型(中等型)、初步淘汰家系类型(淘汰型)3种家系类型,建议8个表现较好的家系可用于生产,分别为169号、114号、177号、32号、3号、145号、158号、134号。
The growth target of 7-year-old progeny forest of 47 Acacia mearnsii in Huangmian forest farm was measured.Then,regard both tannin and timber as object to manage Acacia mearnsii plantation.By integrating the index of tannin output and timber volume,family types were divided into three types：superior family type （superior type）,yet to be superior type （medium type）and preliminarily eliminated type （elimination type）.It was found that there were 8 superior families suitable for production,including No.169,114,177,32,3,145,158 and 134.
