| 摘 要： | 对红锥纯林、红锥×杉木混交林以及红锥×木荷×杉木混交林等不同模式造林试验研究结果表明 ,在 3种不同混交模式中 ,以红锥杉木混交效果最好 ,不但能明显地提高红锥的造林成活率 ,且两者混交种间关系较为协调 ,空间分布格局合理 ,充分利用营养空间 ,混交林分的产量和质量得到了明显的提高。 18年生红锥杉木混交林中红锥的平均树高、胸径、单株材积分别达 14 75m、16 5 0cm和 0 15 6 1m3 ,比红锥纯林分别提高了 10 0 0 %、14 34%、36 93% ,林分蓄积量高达 2 71 4 7m3·hm-2 ,是纯林的 1 30倍 ,可见红锥与杉木混交是值得闽南地区推广应用的针阔混交模式

| Abstract: | The results show that the mixed effect of Castanopsis hystrix and Cunninghamia lanceolata is best of mixed effects of 3 different mixed patterns.Not only can the mixture evidently improve the afforested survival rate of C.hystrix, but the interspecific relations are relatively coordinative with the mixture of them,the spatial distribution pattern is reasonable,the nutritional pattern is fully utilized,the yields and quality of mixed stands are improved evidently.The average tree height,dbh and single tree volume of C.hystrix in 18 year old C.hystrix and C.lanceolata mixed forests respectively reach 14 75 m,16 50 cm and 0 1561 m 3,which increase by 10 00%,14 34% and 36 93% as compared with those of C.hystric pure forests,respectively,the stand stocking reaches up to 271 47m 3·hm -2 ,1 30 times as large as that of pure forests,it is thus clear that C.hystrix and C.lanceolata mixture is the broadleaf conifer mixed pattern worth popularizing and applying in south Fujian areas. |
