The Effect of Drip Irrigation with Saline Water on Growth and Ion Uptaking of Cotton Abstract：A field experiment was carried out to evaluate the effects of irrigation with saline water at different salinity levels on growth and ion uptaking and distribution of cotton. The mulched drip irrigation was adopted. Cotton irrigated with 3.62 dS·m-1 saline water did not affect the dry matter accumulation significantly. During the growing season，the Cl- ，Ca2+ and Na+ concentration of cotton kept increasing. The K+，Cl- and Ca2+ concentration rose，Na+ concentration unchanged with increasing of water salinity levels. The majority of salt ion was transported from root to shoot，and then mostly accumulated in leaves and stems. The ion compartmentation in cotton which maintained the balance of ion of cotton could improve the salt tolerance. The Ca2+ in applied water might affect the uptaking and distribution of mineral composition in cotton.
