通过采用修枝强度30％、40％、50％和不修枝四种处理方式对福建柏(Fokienia hodginsii)人工林进行实验,分析不同修枝强度对福建柏生长指标的影响,旨在为福建柏人工林制定合理的经营管理措施提供依据.结果表明:随着修枝强度的增加,福建柏的胸径、树高、高径比、单株材积和生物量均有所增加,当修枝强度为50％时,各项指标值最大,分别为 7.83 cm、6.84m、87.40％、0.018m3 和 27.80 kg.
Effects of Different Pruning Intensities on the Growth Characteristics of Fokienia Hodginsii
The effects of different pruning intensity on the growth index of Fokienia hodginsii plantation were analyzed by using 30％,40％,50％and no pruning.The purpose of this study was to provide a basis for the development of reasonable management measures for Fokienia hodginsii plantation.The results showed that the DBH,tree height,height-diameter ratio,individual volume and biomass of Fokienia hodginsii increased with the increase of pruning intensity.When the pruning intensity was 50％,the values of each index were the largest,which were 7.83 cm,6.84 m,87.40％,0.018 m3 and 27.80 kg,respectively.
