摘要
2012~2015年间,于赣南南方低丘陵山地进行了杂交松的造林试点。本研究共设计了海拔高度、坡位、坡向的9个地形因子组合的正交设计,测量胸径、株高、枝下高、冠幅,以及2015年春梢生物量等指标。运用方差分析、相关性分析以及综合生长性状评价等分析方法,筛选出最适杂交松造林的地形因子组合2个:分别位于海拔高度200~300m的下坡阳坡及其上坡半阴坡坡地。
During the period of 2012~2015,the study on hybrid pine plantations was designed the orthogonal design of the 9 terrain factors on altitude,slope position and slope direction in low hilly region of southern Jiangxi Province,measures many index of DBH,height,branching height,crown width,and the 2015 spring shoot biomass. The suitable site conditions were screened out by using the means of variance analysis,correlation analysis and evaluation results of the comprehensive growth traits of different growth indicators. The results showed that,there were 2 optimum terrain combinations for hybrid pine plantation,located in altitude 200~300 m downhill and uphill slope half shady slope,respectively.
