对辽宁省铁岭市东部山区野生经济植物榛子样品中的常量营养元素P、K、Ca、Na、Mg、S,14种营养微量元素和稀土元素含量进行了分析.结果表明,本区的榛子样品其主量元素化学特征属K>P>Ca型,其中Na元素含量变异系数最大,为44.27.微量元素含量水平均在植物元素含量正常值变化范围内,由高到低,元素含量排列顺序为;Mn>Si>Fe>Zn>B>Cu>Ni>F>Cr>Mo>Co>Se>I>V.其中,V元素变异系数最大,为93.18.稀土元素总量∑REE(平均值)为29.66×10-9,属低含量.元素相关性分析表明,元素K与Na、Mg,S与Mg、Ca,P与K、Na、Mg、Ca,Fe与Mn,Co与Mn,Cu与Zn之间,在0.01水平都表现出极显著的正相关,反映这些元素之间的吸收积累有很好的协同作用.
The contents of 14 kinds of trace elements and rare earth elements (P, K, Ca, Na, Mg, S) in hazelnut samples of wild economic plants in the eastern mountainous area of Tieling of Liaoning Province were analyzed.The results showed that the hazelnut samples The main chemical elements of the genus are K> P> Ca type, in which the coefficient of variation of Na element is the largest, which is 44.27. The content of trace elements in the range of normal value of plant element content, from high to low, the order of elemental content is V> V> V, and the largest variation coefficient of V element was 93.18. The total amount of rare earth elements ΣREE (average) And 29.66 × 10-9, respectively. The elemental correlation analysis showed that element K and Na, Mg, S and Mg, Ca, P and K, Na, Mg, Ca, Fe and Mn, Co and Mn, Cu and Zn between the 0.01 levels showed a significant positive correlation, reflecting the accumulation of absorption between these elements have a good synergy.
