研究了百山祖冷杉(Abies beshanzuensis)分布区适生立地表层土壤养分及其与百山祖冷杉枝叶营养元素含量的相关性。结果表明,土壤pH5.11~6.42,土壤有机质含量、全氮含量、速效磷含量、速效钾含量分别为119.075 0 g/kg、2.196 2 g/kg、15.016 3 mg/kg、136.215 2 mg/kg;百山祖冷杉对土壤N、P、K富集能力均较高,而对微量元素富集能力较弱,且枝部和针叶均未检出Na元素;较高的土壤N含量,可相应显著提高百山祖冷杉叶N、K含量水平,较高的土壤P含量,则显著抑制百山祖冷杉叶对K和枝对N的积累水平,较高的土壤Cu含量显著降低了Cu元素在叶器官中的积累,而显著增加了枝条中Cu和Zn的积累水平,较高的土壤Fe含量则显著促进了针叶中Fe元素和枝中Fe、Mn元素的积累水平。
In this study, the soil nutrients of the topsoil of Abies beshanzuensis and its correlation with nutrient content of Abies bezuzuensis were studied. The results showed that the contents of soil organic matter, total nitrogen, available phosphorus and available potassium were 119.075 0 g / kg, 2.196 2 g / kg, 15.016 3 mg / kg and 136.215 2 mg / kg respectively at pH5.11 ~ 6.42, ; Abalone fir Abundance of N, P, K enrichment of soil were high, and the enrichment of trace elements weaker, and the branches and conifers were not detected Na element; higher soil N content, may Correspondingly, the content of N, K and the content of P in the leaves of Abies germans were significantly increased, while the accumulation of K and branches on N was significantly inhibited in Abies fargesii, while the content of Cu in the soil was significantly decreased Leaf organs, but significantly increased the accumulation of Cu and Zn in shoots. Higher soil Fe content significantly enhanced the accumulation of Fe and Mn in the needles and branches.
