摘要
对巨尾桉采取全修方式进行林地清理下3种萌芽高度(1.00、1.50、2.00 m)和采取炼山方式进行林地清理下4种萌芽高度(0.6、1.0、1.0、2.0 m)进行定株除萌,结果表明,2年生巨尾桉各处理之间树高、胸径生长差异不显著。考虑粗壮萌芽条选择、萌芽条养分消耗和生产成本,定株除萌高度在1.0~1.5 m为佳。
Singling coppice sprouts of Eucalyptus grandis×E.urophylla following 3 bud height(1.0,1.5,2.0 m)of eucalyptus urophylla grandis growed in weeded woodland and 4 bud height(0.6,1.0,1.5,2.0 m)growed in woodland with control burning were studied.The results showed that there was no significant difference between the two-years-old Eucalyptus grandis×E.urophylla in average heights and DBHs among treatments.Considering the factor about the burgeon of selection and nutrient consumption,costs,singling sprout height of 1.0-1.5 m was better.
