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。
By comparing 2.5 years old climber cultivated young clonal clones of clonal plantations and live plantations, the growth, biomass and productivity of trees in different seasons were compared. The results showed that: the height of clonal cinnamomum clods, the diameter growth ratio The analysis of variance showed that the differences of tree height between two types of plantations of Cinnamomum camphora in different seasons experienced the process of “insignificant - significant - extremely significant” The growth curve of four-season camphor plantation accorded with the growth law of Logistic mathematical equation. The biomass of the 2.5-year-old camphora was 31 241.99 kg.hm-2, accounting for only 59.2% of the clonal forest, and the difference of the net productivity was also similar. The litterfall of the climber reached 9 145.45 kg.hm-2, 1.92 times the seedling plantation.
