摘要
在福建邵武卫闽林场建立了马尾松、福建柏(建柏)、闽粤栲、木荷纯林以及马尾松与其他3个树种的混交林(混交比例1∶1)的试验林,混交林有3种模式:块状(3株×3株)、横排带状(3行×3行)、竖排带状(3列×3列),株行距均为2 m×2.5 m(初植密度2000株/hm^2)。试验后25年的结果表明:13种林分类型生长量差异显著,蓄积量大小顺序为:建柏纯林>闽粤栲纯林>马尾松×木荷竖排带状混交>马尾松×建柏竖排带状混交>马尾松×木荷块状混交>马尾松×建柏横排带状混交>木荷纯林>马尾松×木荷横排带状混交>马尾松×建柏块状混交>马尾松纯林>马尾松×闽粤栲竖排带状混交>马尾松×闽粤栲块状混交>马尾松×闽粤栲横排带状混交,其中蓄积量最高的建柏纯林(279.20 m^3/hm^2)是蓄积量最低的马尾松×闽粤栲横排带状混交(84.32 m^3/hm^2)的3.11倍。马尾松与木荷混交效果最好,其次是马尾松与福建柏混交,马尾松与闽粤栲混交效果最差,其蓄积量低于两个树种的纯林。
Trial forest plantations of pure Pinus massoniana, Fokieniahodginsii,Castanopsisfissa and Schimasuperba, and mixed forest plantations of P. massoniana mixed with each of the other 3 species(mixed ratio 1∶1) were established. There were 3 kind of mixed models in the mixed plantations: mixture by group(3 trees×3 trees), mixture by horizontal strip(3 rows×3 rows) and mixture by vertical strip(3 columns×3 columns). The planting space was all 2 m×2.5 m(planting density 2000 trees·hm^-2). Twenty-five years after the trial, there were significant difference in stand growth among 13 stand types. Stand volume were in the order pure F. hodginsii>pure C. fissa>P. massonianamixed with S. superba by vertical strip> P. massonianamixed with F. hodginsii by vertical strip>P. massonianamixed with S. superba by group>P. massonianamixed with F. hodginsii by horizontal strip>pure S. superba> P. massonianamixed with S. superba by horizontal strip> P. massonianamixed with F. hodginsii by group>pure P. massoniana> P. massonianamixed with C. fissa by vertical strip> P. massonianamixed with C. fissa by group> P. massonianamixed with C. fissa by horizontal strip. Stand volume was highest in the pure F. hodginsii plantation(279.20 m^3·hm^-2) and it was 3.11 times as high than the lowest in the P. massonianamixed with C. fissa by horizontal strip. The best mixtures were in the models of P. massonianamixed with S. superba, followed by P. massonianamixed with F. hodginsii. The worst mixtures were P. massonianamixed with C. fissa, and their stand volumes were lower than both of the two pure plantations.
