| 摘 要： | 采用5个处理3次重复的完全随机区组设计对闽楠、裂斗锥与马尾松混交林生长效应进行研究。结果表明：混交对林木生长有促进作用,混交林中闽楠的胸径、树高、林分生物量明显高于闽楠纯林,混交林中裂斗锥的胸径和林分生物量也显著高于裂斗锥纯林,两种混交林林分生物量均高于各自纯林;不同林分林下植被生物量大小排序为混交林大于纯林,混交林均不同程度的提高了林下植被生物量和凋落物量。

| Abstract: | The growth effect of the mixed forest of Phoebe bournei, Castanopsis fissa and Pinus massoniana were investigated by the randomized complete block design of 5 treatments and 3 replications.The results showed that the mixing of forest has a promoting effect to tree growth,the DBH,tree tree height,stand biomass of Phoebe bournei in the mixed forests were significantly higher than those of nanmu pure forest,the DBH and stand biomass of Castanopsis fissa were also significantly higher than those of nanmu pure forest, the biomass of two kinds of mixed forest was higher than pure forest,the undergrowth biomass of the mixed forest was higher than pure forest too, the undergrowth biomass and litter were improved by mixed-forest. |
