| 摘 要： | 通过对2.5年生香樟组培幼态枝扦插无性系人工林和实生人工林,不同季节林木生长量、生物量及生产力进行对比研究,结果表明:香樟扦插无性系林树高、地径生长量比实生林具有优势;方差分析表明,香樟2种类型人工林树高在不同季节的生长差异经历"不显著-显著-极显著"的过程,而地径的生长差异不显著;2种类型香樟人工林四季的生长曲线符合Logistic数学方程的生长规律。2.5年生香樟实生林生物量达31 241.99 kg.hm-2,仅占无性系林的59.2%,净生产力的差异也相似;香樟无性系林分凋落物达9 145.45 kg.hm-2,是实生苗人工林的1.92倍。

| Abstract: | Comparative study was conducted on 2.5 years old Cinnamomum camphora plantation established using clone cuttings and seedlings,growth increment biomass and productivity of different season were chosen as the indicators.The study results the performance of plantation established with clone cuttings was better than that established with seedlings.The results of variance analysis implied that the tree height difference of two types of plantations experienced the procedure of not significant,significant and ver... |
