Abstract: In this study, the contrast experiment of combined application of phosphogypsum and humic acid fertilizer in three levels and exclusive application of phosphogypsum and humic acid fertilizer was carried out to evaluate their improvement effect on the salinized-alkalinized cultivated land. The results showed that the effect of combined application of phosphogypsum and humic acid fertilizer was superior to that of exclusive application of phosphogypsum and humic acid fertilizer, and the application of 900 kg/667m^2 of phosphorusgypsum combined with 1 000 kg/667m^2 humic acid was recommended.
