Effects of Different Soil Amendments on Coastal Saline-alkali Soil in North Jiangsu
Abstract：For studying the effects of different amendments on soil salinity,nutrient and crop growth,experiments were carried out in the saline-alkali coastal field located in North Jiangsu,gypsum,weathered coal and microorganism agents were added in the top soil of the experimental plot（0 to 20 cm） before tillage.Results showed that all the amendments had the property to improve soil properties,decrease soil salinity,pH and baleful ions（especially Na＋ and Cl-）,increase N,P and organic matter content,and promote crop growth to an extent.In the 0 to 20 cm soil layer,the soil salinity content,Na＋ and Cl-in the plot applied with gypsum,weathered coal and microorganism agents reduced by 37.5%,55.4% and 172.8%,34.5%,14.0% and 129.5%,and 24.0%,34.7% and 16.4% compared to the CK,and the yield increased by 91.3%,43.0% and 15.4% respectively.
