摘要/Abstract

摘要： 为了分析伴生植物盐角草和星花碱蓬在一个生育期内不同器官中Na⁺、K⁺、Ca²⁺及Mg²⁺含量的变化，利用火焰分光光度法和原子吸收法测定了两种植株不同发育时期的根、茎、叶中这4种阳离子含量。结果显示这两种植物根和茎中4种离子的积累趋势和叶器官中不同：Na⁺、K⁺元素含量随着植物的发育呈下降趋势，而在叶器官中则呈上升的趋势；两种植物根和茎及盐角草的叶器官中Ca²⁺、Mg²⁺元素的含量随生育期的发育呈由低到高再降低的趋势，而星花碱蓬的叶器官中这两种离子的含量则表现为由高到低再升高的趋势。两种植物除了Ca²⁺、Mg²⁺的积累趋势在两种植物间存在有差异外，其余指标的变化趋势基本一致。尤其对Na⁺的积累，两种植物Na⁺的含量占根部干重的3%左右，占茎部干重的5%左右，占叶部干重的10%左右。表明伴生植物盐角草和星花碱蓬具有改良盐碱地的良好潜能，可以作为改良盐碱地的优良种植资源。

Abstract: In order to analyze the change of Na⁺, K⁺, Ca²⁺ and Mg²⁺ in root, stem and leave at different growth stages of associated plants Salicornia europaea and Suaeda stellatiflora, these cations were determined by flame spectrophotometry and atomic absorption spectrometry. The result showed that the trends of Na⁺, K⁺, Ca²⁺ and Mg²⁺ were different in root and steam from leaf organs. The contents of Na⁺ and K⁺ were decreased in the root and stem, increased in leaf tissues with the development of plants. The accumulation of Ca²⁺ and Mg²⁺ were from low to high to reduce in roots and stem with two species growth and development, as same as in leaves of S.europaea. But accumulation of Ca²⁺ and Mg²⁺ were from high to low to up trend in leaves of S.stellatiflora with its growth and development. These two halophyte could absorb the Na⁺ about 3% of roots, 5% of stems, and 10% of leaves of dry weight. The associated plants S.europaea and S.stellatiflora could become functional plants in improving saline-alkali soil, because these two plants have excellent potential to remove plenty of salt.
