摘　　要：通过定量分析了河套灌区萌生苗造林小美旱杨不同部位八大离子含量 ,研究得出 :叶中K+ 、Na+ 含量在 5月份最高 ,以后各月逐渐递减 ,Ca2 + 从 5月开始不断递增。—年生枝、多年生枝中的SO2 -4 含量从 5 (4 )月开始不断递增。心材、边材中Cl-、HC0 -3 、Ca2 + 都是由高 (4月 )到低 (6月 )再到高的 (10月 )。根中Ca2 + 、Mg2 + 在各月份的含量较稳定。各部位各月份均无CO2 -3 的存在。Eight Ions Gontent in different parts of grminate Poplar which collocted from Hetao-irrigated district was analysed.The research showed that K + and Na + content in the leafe was the highest in May and decreased progressively later,Ca 2+ increase progressively since May.One year branch and many year branches SO 2- 4 increased progressively from May (April).The heartwood and sidewood for Cl -,HCO - 3 and Ca 2+ are hith from April to low June to high October.Ca 2+ and Mg 2+ in root are comparatively stable.There is no CO 2- 3 in any part at any month.
