| 摘 要： | 在三代杉木林采伐迹地营造杉木火力楠混交林（５：２）试验，结果表明：１０年生杉木火力楠混交林林分的生产力和生物量比对照杉木纯林有所提高；单株生物量大小顺序为：混交林中杉木＞纯林杉木＞混交林中火力楠；在根系组成中，火力楠＜０．１ｃｍ须根所占比例（１５．４４％）比杉木（１．７９％）高，混交林林分年凋落物量和枯枝落叶现存量均高于对照的杉木纯林

| Abstract: | Expriment of planting mixed forest of Chinese fir and Michelia macclurei (5∶2) on cutover of Third Chinese fir rotation has been done, the result shows: The stand productivity and biomass of mixed forest (10 year old) of Chinese fir and Michelia macclurei improves to some extent, contrasting to unmixed forest of Chinese fir; The order of tree biomass is Chinese fir in mixed forest > Chinese fir in unmixed forest>Michelia macclurei, in mixed forest; In the composition of root system, the proportion of fibrous root (<0 1cm) of Michelia macclurei(15 44%) is higher than that of Chinese fir (1 79%) Annual litter fall and extand litter fall and extand litter fall of mixed forest are both higher than unmixed forest of Chinese contrasted |
