| 摘 要： | 采用化学和数学分析方法对新疆杨不同部位(叶、枝、干、根)8个可溶性盐离子含量进行了研究。结果表明：(1)新疆杨中无CO3^2-存在;(2)新疆杨各部位各个生长时期阳离子中K^ 含量最大,Na^ 含量最小;阴离子中HOQ3^-含量最大;(3)新疆杨树体内的主导离子是Ca^2 、HCO3^-、Cl^-;(4)新疆杨一年生枝、多年生枝、心材和边材的离子分布年内动态相似,叶和根有各自独特的特点。

| Abstract: | The eight soluble salt ions in different parts of Populus alba L.var.pyramidalis were analyzed with chemical methods and mathematical methods.The result showed (1)There was no CO_3~(2-)in any parts at any month;(2)In any parts at any month K~+ content was the highest and Na~+ content was the lowest in positive ions ;HCO_3~- content was the highest in negative ions;(3)The principal components of Populus alba L.var.pyramidalis was HCO_3~- ?Cl~- and Ca~(2+);(4)The dynamic regularity was similar in one year branches,many year branches,heartwood and sapwood ,leaves and roots had their own characters. |
