摘 要:2004年在福建省安溪县进行了杉木低产林分改造营造福建柏火炬松混交林试验。结果表明:经过10a的经营管理,林木生长效果较好。10a生的福建柏火炬松混交林的林分生长量均有所提高,其中,平均树高11.92%、2.52%,胸径粗13.42%、14.58%,树冠大13.46%、1.72%,枝下高大4.92%、5.81%,郁闭度大2.15%、5.55%,单株材积大21.05%、25.45%,蓄积量大11.71%、23.69%。土壤肥力N、P、K分别提高0.97%、1.96%,1.49%、4.62%,0.49%、0.82%。The low yield stand of Chinese fir was transformed to construct the forest of Fokienia hodginsii and Pinus taeda in Fujian, and the forest growth effect was better after 10a management.The results showed that the stand growth of 10 years of the mixed forest were all improved,including the average tree height by 11.92% and 2.52%,the diameter at breast height by 13.42% and 14.58%,crown by 13.46% and 1.72%,branch under the height by 4.92% and 5.81%,closing degree by 2.15% and 5.55%,individual vol- ume by 21.05%and 25.45%,accumulation by 11.71% and 23.69%. The soil fertility N,P,K were all im- proved by 0.97%,1.96%, 1.49%,4.62%,0.49% and 0.82%.
