摘要 在福建省大田梅林国有林场,对5年生的福建柏人工林进行修枝试验,修枝3 a后调查分析树高、胸径和枝下高的生长情况。结果表明:修枝对幼林期福建柏人工林的胸径生长无显著影响,对树高、单株立木材积和枝下高具有正向促进作用,作用由大到小为:修剪枯枝+2轮活枝〉修剪枯枝〉不修枝。与不修枝相比,修枝3 a后,修剪枯枝处理树高生长增加了57.61%,单株立木材积生长量提高44.86%,枝下高增长了4.43倍;修剪枯枝+2轮活枝处理树高生长量提高55.14%,单株立木材积生长量提高72.37%,枝下高增长了5.62倍。 A pruning test on 5-year old plantation was conducted to examine the pruning effect on growth of Fokienia hodginsii.on Meilin national forest farm in Fujian Province.The results showed that there were significant pruning effects on the growth including tree height,standing wood volume and height under branch,but there were no significant effects on the diameter at breast height,in 3 years after pruning.And the order of pruning effect was pruning dead branchespruning dead branches and 2 round branchesno pruning.Furthermore,pruning dead branches could get more 57.61% growth on tree height,more 44.86% growth on standing wood volume,and more 4.43 times increases on height under branch than no pruning.Especially,pruning dead branches and 2 round branches could get more 55.14% growth on tree height,more 72.37% growth on standing wood volume,and more 5.62 times increases on height under branch than no pruning.
