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.
