Potexperiments were conducted in greenhouse on effects of regulatory measures including fertilization, irrigation, chemical soil amendment on distribution of soil salt and ionic uptake by crop. The results showed that fertilization increased elec tric conduct ivity of the surface soil. On the whole, electric conductivity of the surface soil in the treatment with high application rate of fertilizer was higher. Irrigation decreased electric conductivity of the surface soil layer. In the treatment with soil amendment CaSO₄ electric conductivity of the surface soil layer increased at the early stage, but came back again at the middle and later stages. Fertilization and irrigation improved the growing environment for barley and enhanced its salt resistance. When the total quantity of irrigation was maintained at 375 mm, the treatment of irrigation once every three days was superior to the treatment of irrigation once every two days in reducing salt concentration and restraining soil alkalinization. Na⁺ content in barley stem was higher than that in leaves demonstrating the function of barley retaining Na⁺ in the stem thus mitigating Na⁺ damage to the leaves. Cl^- content in barley s leaves and stems was higher than K⁺ and Na⁺ content, suggesting that more Cl^- was transported through roots to the above ground part. Modifier showed the good result of increasing K⁺ content and decreasing Na⁺ content in crop. The soil amendment showed positive effect in increasing K uptake, decreasing Na⁺ content in the plant and alleviating stress of the plant from saltions.
