- Abstract:
- The effect of desulphurized gypsum from coal-fired power plant on salt transport in saline-alkali soil under different irrigation amount were researched by soil column simulation test,in order to explore desulphurization gypsum best rinse irrigation water.The results showed that the content of Na+ in 0-20 cm soil layer decreased under different irrigation amount,and the pH,alkalinity,conductivity and Na+ content in each layer were the lowest when the irrigation amount was 85% of field capacity (T85%).Ca2+ content in 0-20 cm soil layer increased after applying desulfurization gypsum,and the overall Ca2+ content was T85%
