| 摘 要： | 在３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：混交林林分营养元素 量比对照林增加４．１１％，乔木层和枯枝落叶层的营养元素贮量分别是对照林的１．０１倍和５．０２倍，杉木火力楠混交林林分年凋落物量对照林的５．１１倍，营养元素循环速率亦比纯林大。

| Abstract: | Experiment of planting mixed forest of Chinese fir and Michelia macclurei(52) was made on cutover area of the third Chinese fir,the results indicate:comparing with the control forest,tatal nutrient elements of mixed forest stand increased by 4.11%,the nutrient elements reserve of tree stratum and litterfall are 1.01 times and 5.02 times as much as that of control separately.Annual stand litterfall of mixed forest of Chinese fir and Michelia macclurei is 5.11 times as much as that of control forest,the nutrient elements cycle rate (return/uptake) is higher than that of unmixed forest. |
