摘要
本文研究了竹秆和竹叶的微量元素。雷竹和毛竹的竹秆含有Fe、Al、Ca、Mg、Ba、Mn、Zr、Ti、Pb、Sn、Ga、Cr、Ni、Mo、Cu、Yb、Zn、Sr、K、Na、P、B 和 Si 等23种微量元素,刚竹、苦竹和石竹的竹秆含有22种微量元素,少了一种 Cr 的元素;箬竹、刚竹、毛竹、雷竹和淡竹的竹叶含有20种微量元素;毛竹和雷竹的竹叶微量元素与毛竹和雷竹的竹秆微量元素比较,竹叶少了Sn、Cr 和 Yb 三种微量元素。
Having studied on the trace elements in culms and leaves of bamboos,the writers reported:The culms of Ph.Praecox and Ph.Pubescens contain 23 species of trace elements.They are: Fe,A1,Ca,Mg,Ba,Mn,Zr,Ti,Pb,Sn,Ga,Cr,Ni,Mo, Cu,Yb,Zn,St,K,Na,P,B,and Si.While the culms of Ph. viridis,Pl.amarus and Ph.nuda Mcdare contain 22 species of trace elements.The lacked element is Cr.in leaves,there are 20 species of trace elements in In.tessellatus,Ph.viridis,Ph. pubescenes,Ph.praecox and Ph.geauea.Species of trace elem- ents in leaves is three less than in culms in Ph.pubescenes and Ph.praecox.The lacked elements are:Sn,Cr,and Yb.
