杉木与七种阔叶树混交造林效果的初步研究

通过对7种优良乡土阔叶树种与杉木混交林的调查研究,结果表明:杉阔混交林提高了林分蓄积量,促进杉木和阔叶树种成林、成材。混交林中的杉木普遍比杉木纯林生长好,只有杉檫混交林例外。杉木和木兰科观光木、乳源木莲、壳斗科红锥、格氏栲以及樟科的檫树、樟树混交造林,有利于发展珍贵阔叶树种种群规模,具有推广应用前景。处理好种间关系是营造混交林成败的关键。

The preliminary study on the afforestation effect of the Cunninghamia lanceolata mixed with other seven broad-leaved species

Based on the study of the mixed forest of Cunninghamia lanceolata and other seven broad-leaved species,the result showed that the mixed forests improved the stand volume and promoted the growth of Cunninghamia lanceolata and other broadleaf trees.The mixed forest of C.lanceolata is better than the pure's,in addition to the mixed forest of C.lanceolata and Sassafras tzumu.C.lanceolata mixed with Tsoongiodendron odorum,Manglietia yuyuanensis,Castanopsis hystrix,Castantpsis kawakamii and Cinnamomum camphora,S.tzamu are advantageous to develop the scale of broad-leaved population and have promoted and application prospect.It is important to deal well with the inter species relationship for building the mixed forests.
