| Abstract: |
| A pot experiment was conducted to study the effect of by-product of flue gas desulphurization （BFGD） and furfural residue on ameliorating saline-sodic soil．The results showed that：pH sobuble salts and the exchangeable sodium percentage （ESP） were decreased at different degrees by applying the BFGD and furfural residue but most obvious effect was made by applying the BFGD and furfural residue at the same time and pH soluble salts and ESP from the initial9．2 10．71‰ and 25．97％ went down to 7．5 9．43‰ and 9．52％；Sunflower germination rate was as high as68．3％ 60％ higher than that of the control. |
