摘　　要：本文对福建青冈切根苗造林效果进行分析,结果表明:切根苗造林可以提高造林成活率,幼林生长状况良好。经方差分析,福建青冈切根II型苗木营造纯林与常规苗木营造纯林平均胸径间差异达到极显著水平。切根II型苗木与杉木混交林和其纯林比,平均胸径、平均树高分别增加4.3%和6.3%,福建青冈切根II型苗木营造纯林与切根I型苗木营造纯林,常规苗木营造纯林平均胸径间差异达到显著水平,切根II型苗木营造纯林与常规苗木营造纯林平均树高间差异达到显著水平。在混交状态下福建青冈生长更好。切根,尤其是切根II型切根方式可以提高造林效果,与杉木混交能够促进福建青冈生长。建议在生产上大力推广福建青冈切根苗造林,同时提倡营造混交林,充分利用树种间生物学特性的互补性和协调性培育优质林分。The afforestation effect of the root-cutting seedlings of Cyclobalanopsis chungii was analyzed. The result showed the afforestation survival rate increased by the root-cutting seedlings and the young forest of C. chungii grew well. By the analysis of variance, there was great significant difference between the pure forest established by the root-cutting style II seedlings and the pure forest established by the normal seedlings in average DBFI. Compared the mixed forest of C. chungii established by the root-cutting style II seedlings and Cunninghamia laceolata with the pure forest established by the root-cutting style II seedlings, the average DBH and tree height increased 4.3% and 6.3%, respectively. There was signifi- cant difference between the pure forest estabhshed by the root-cutting style II seedlings and the pure forest established by the root-cutting style I seedlings or the pure forest established by normal seedlings in average DBH. There was significant difference between the pure forest established by the root-cutting style II seedlings and the pure forest established normal seedlings in tree height. The mixed forest grew better than others. The root-cutting seedlings, especially the style II, im- proved the afforestation effect. The forest of C. chungii mixed with C. laceolata improved the growth of C. chung/i. The technique on the forest established by the root-cutting seedlings should be extended in the production. At the same time, the author advocated the mixed forest to make full use of the interspecies biological complementarity and harmony for the cultivation of high quality C. chungii forests.
