四合木（TetraenamongoliaMaxim）常量元素、微量元素、氨基酸和热值的初步分析

The Preliminary Analysis of Majorelements,Traceelements,Amino Acid and Calorific Value of Tetraena mongolia Maxim

对四合木的化学成分，包括常量、微量化学元素、氨基酸以及热值进行了初步分析，结果表明：从常量元素看四合木属Ｃａ＞Ｎａ＞Ｍｇ＞Ｋ型；从微量元素看属Ｆｅ＞Ｍｎ＞Ｃｕ＞Ｚｎ型；叶片氨基酸总含量为７．１６％属于中等水平低于沙冬青（Ａｍｍｏｐｉｐｔａｎｔｈｕｓｍｏｎｇｏｌｉｃｕｓ）．热值水平很高，表现为老枝（１９．４４ＭＪ·ｋｇ￣（－１））＞主根（１９．１５Ｍｇ·ｋｇ￣（－１））＞叶片（１０．１８ＭＪ·ｋｇ￣（－１））．

he chemical compositions of Tetraena mongolia including major elements,trace elements,amino acid and calorfic value,are analysed.The result has showed that:in regard to tnajor ele-ments, the Tetraena mongolia belongs to “Ca>Na>Mg>K type”;in regard to trace elements,itbelonged to “Fe>Mr>Ca>Zn type”.The total amount of amino acid belongs to medium level(7.16%).and is lower than that of Ammopiptanthus mongolicus. The calorific value is as high asfollows:old branch(19.44MJ·kg￣(-1)),main root(19.15MJ·kg￣(-1)),and leaf(10.18MJ·kg￣(-1)).
