铁岭市东部山区野生经济植物榛子营养元素地球化学特征

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.

PHYTOGEOCHEMISTRY OF THE WILD ECONOMIC PLANT Corylus FROM THE EASTERN MOUNTAINOUS AREA OF TIELING, LIAONING PROVINCE

The wild economic plants of Corylus are collected from the eastern mo untains area of Tieling, Liaoning Province. The main nutrition elements of P,K, Ca, Na, Mg and S, 14 kinds of nutrition microelements and rare earth elements (R EEs) in Corylus are analyzed. The results show that the characteristics of main elements in the samples belong to the type of K >P >Ca. The greatest variation i s found in Na concentration among the microelements, with variation coefficient of 44.27. The average contents of microelements are all in the normal scale of p lant element contents.The mean microelement contents follow an order as Mn >Si > Fe >Zn >B >Cu >Ni >F >Cr >Mo >Co >Se >I >V. Among them, the element V is with th e greatest variation coefficient (93.18). The gross of REEs, with mean value of 29.66 ×10-9, belong to the low content level. The correlation analysis of elem ent concentration in Corylus reveals that, at the level of 0.01, correlations ex ist between K and Na/Mg, S and Mg/Ca, P and K/Na/Mg/Ca, Fe and Mn, Co and Mn, an d Cu and Zn.The results suggest a well cooperating effect on absorbability and a ccumulation among the elements.
