Aimed at screening effective soil amendments to the soda salinesoil，a stationary experiment was carried out in the field. FeSO4，Al2(SO4)3，weathered coal and humic acid amendment(DS -1997)were applied to study the effects ofdifferent soil amendments on maizebiomass，soilpH，EC，ESP value，soil salt and nutrientcontains，in contrast no soilamendment was applied. The results showedthat，compared with CKtreatment，the application of the four amendmentssignificantlydecreasedsoilpH，ESPvalue，thecontents ofexchangeNa + and watersoluble Na+contentsby2.87%～5.39%，38.72%～75.21%，52.33%～ 78.14% and 89.54%～96.61%，respectively，all of them showed the greatest decrease with weathered coal. Soil organic matter and Olsen-P contents showed significantly increase with the application of weathered coal and DS-1997. Compared with CK treatment，the SOM and Olsen -P contents increased by 88.51% and 38.70% inweatheredcoal，by 63.18% and 33.33% in DS -1997( P<0.05). Different amendments could improve maize biologicalcharacteristics，there were no significant differences among four amendments，compared with CK treatment. In summary，the application of weathered coal could significantly improve soda salinizedsoil，by decreasing soil pH and ESPvalues，improving soil saltcomposition，increasing soil nutrient content and maize yield.
