对1年生杉木扦插苗根、茎、叶中8种营养元素含量的分析结果表明:8种营养元素含量在杉木扦插苗的不同部位差异极显著,不同部位比较N、P、Mn、Zn含量以叶中最高,而K、Ca、Mg、Cu以根中最高,叶中营养元素含量变异系数相对较小。无性系间各营养元素含量及部位与无性系交互作用差异均达极显著水平。N、Mg含量与苗高、地径呈显著相关。
The results of the analysis of the contents of 8 nutrients in roots, stems and leaves of 1-year-old Chinese fir cuttings showed that there were significant differences in the contents of 8 nutrients in different parts of Chinese fir cuttings. The content of N, P, Mn and Zn in different parts The highest in leaves, and the highest in roots of K, Ca, Mg and Cu. The coefficient of variation of nutrients in leaves was relatively small. The differences of nutrient content and interaction between clones and clones in clones reached extremely significant level. N, Mg content and seedling height, diameter was significantly correlated.
