摘　　要：在杉木采伐迹地上采用毛红椿+虎皮楠混交林(毛+虎)、毛红椿+杉木混交林(毛+杉)、毛红椿+马尾松混交林(毛+马)和毛红椿纯林(毛纯)4种模式更新,造林6年后比较了不同模式的造林效果,结果表明:造林6年后毛红椿在不同经营方式下产生差异,其中毛+马的地径生长量显著高于其他3种模式,而毛纯、毛+虎和毛+杉3种模式之间地径生长量无显著差异,表明毛红椿与马尾松混交时有最高的地径生长量;不同混交树种之间马尾松地径生长量最高,虎皮楠最低,而杉木与马尾松和虎皮楠均无显著差异。不同树种的地径相对生长率以虎皮楠的1.59cm·a^(-1)最高,马尾松的1.32 cm·a^(-1)次之,杉木为1.24 cm·a^(-1),毛红椿的相对生长率则为0.68~0.78 cm·a^(-1)。造林6年后不同树种的树高在树种间及样地间均无显著差异,高径比在树种间亦无显著差异。综合性状评价表明,从促进毛红椿的生长看,不同模式间毛红椿+马尾松混交模式的得分最高,其次为毛红椿+虎皮楠混交模式,毛红椿纯林得分最低;从不同混交树种的生长成效来看,马尾松得分最高,其次为杉木,虎皮楠得分最低。The effects of 4 regeneration modes in Cunninghamia lanceolata plantation cutover lands were compared after 6 years afforestation,including Toona ciliata and Daphniphyllum oldhamii mixed forest,T.ciliata and C.lanceolata mixed forest,T.ciliata and Pinus massoniana mixed forest,T.ciliata pure forest.The results showed that T.ciliata under different management modes after 6 years afforestation was different,and ground diameter growth of T.ciliata and P.massoniana mixed forest was significantly higher than that of the other three modes,but there was no significant difference among the other three modes,indicating that ground diameter growth of T.ciliata and P.massoniana mixed forest was the highest.The relative growth rate of ground diameter was the highest in P.massoniana and D.oldhamii was the lowest among mixed tree species,but there was no significant difference between C.lanceolata and P.massoniana as well as D.oldhamii.The relative growth rate of ground diameter was highest in D.oldhamii,which reached 1.59 cm·a^(-1),followed by P.massoniana with 1.32 cm·a^(-1),C.lanceolata with 1.24 cm·a^(-1),and T.ciliata between 0.68-0.78 cm·a^(-1).After afforestation for 6 years,there was no significant difference in tree height for different species and plots,and no significant difference in height-diameter ratio between species.Comprehensive trait evaluation showed that in terms of promoting the growth of T.ciliata,T.ciliata and P.massoniana mixed forest had the highest score,followed by T.ciliata and D.oldhamii mixed forest,and the pure T.ciliata forest had the lowest score.In terms of the growth efficiency of different mixed species,P.massoniana had the highest score,followed by C.lanceolata,and D.oldhamii had the lowest score.
