摘要
为了比较研究不同混交种植方式下桉树的固碳能力之间的差异,以福建云霄园岭国有林场作为研究区,采用了2种公式,使用SPSS检验了其显著性,结果显示两种公式之间不存在显著性差异。结合SPSS软件针对不同的树种分别使用了参数检验和非参数检验,探讨了不同混交种植方式下桉树相互之间的生物量是否存在显著性差异。结果表明,大花序桉株间混交株数比例1∶1和株间混交株数比例2∶2之间不存在显著性差异,株间混交株数比例3∶3和株间混交株数比例2∶2与株间混交株数比例1∶1之间均存在显著性差异。托里桉株间混交株数比例2∶2和株间混交株数比例3∶3下的生物量之间不存在显著性差异,株间混交株数比例1∶1和株间混交株数比例2∶2与株间混交株数比例3∶3下的生物量之间均存在显著性差异。比较了不同树种生物量之间的显著性,大花序桉和托里桉的生物量存在显著性差异,而大花序桉要高于托里桉。
In order to compare and study the difference of carbon fixation capacity of Eucalyptus under different mixed planting modes,this paper takes Fujian Yunxiao Yuanling State-owned Forest Farm as the research area,uses two kinds of formulas,and uses SPSS to test their significance.The results show that there is no significant difference between the two formulas.Combined with SPSS software,parametric test and nonparametric test were used for different tree species to explore whether there were significant differences in biomass of Eucalyptus under different mixed planting modes.The results showed that there was no significant difference between the proportion of mixed plant number 1∶1 and the proportion of mixed plant number 2∶2 among plants of Eucalyptus grandiflorum,but there was significant difference between the proportion of mixed plant number 3∶3,the proportion of mixed plant number 2∶2 and the proportion of mixed plant number 1∶1 among plants of Eucalyptus grandiflorum.There was no significant difference between the biomass of Eucalyptus toli under the proportion of mixed plant number 2∶2 and the proportion of mixed plant number 3∶3,but there was significant difference between the biomass under the proportion of mixed plant number 1∶1 and the proportion of mixed plant number 2∶2 and the proportion of mixed plant number 3∶3.Compared the biomass of different tree species,there was a significant difference between the biomass of Eucalyptus grandiflorum and that of Eucalyptus toli.Eucalyptus grandiflorum was higher than that of Eucalyptus toli.
