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. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2018.01.013
