摘　　要：对福建省将乐国有林场森林经营区17年生杉木×福建柏混交林中杉木生长状况进行调查分析。结果表明,混交福建柏后,杉木人工林生长状况得到明显改善,但不同的混交比例影响效果不一。当福建柏混交比例为5%时,杉木树高无显著变化,但胸径增加12.70%,单株立木材积增加37.01%;当福建柏混交比例为15%时,杉木树高增加8.82%,胸径无显著变化,单株立木材积增加36.12%;当福建柏混交比例为25%时,杉木树高无显著变化,但胸径增加11.90%,单株立木材积增加32.83%。The growth of Chinese fir was analyzed in a 17 years old test stand which was mixed with Fokienia hodginsii on the management area of National Forest Farm of Jiangle.The result showed that the growth of Chinese fir was improved in the mixed stand.The tree height of Chinese fir was not significantly changed in the mixed stand with 5%mixed proportion of F.hodginsii,but the diameter at breast height(DBH)could be raised 12.70%and the volume could be raised 37.01%.The tree height of Chinese fir could be raised 8.82%and the volume could be raised 36.12%in the mixed stand with 15%mixed proportion of F.hodginsii,but the DBH was not significantly changed.The tree height of Chinese fir was not significantly changed in the mixed stand with 25%mixed proportion of F.hodginsii,but the DBH could be raised 11.90%and the volume could be raised 32.83%.
