| 摘 要： | 针对滨海盐渍土的特点,采用4种盐碱土改良剂在滨海盐渍土上单独施用和与石膏配合施用,研究施用后对盐渍土离子组成的影响。结果表明:施用改良剂与石膏后,在0～40 cm土层,盐渍土中离子组成比例发生不同程度的变化。pH值、电导率、Na+、K+、Cl-和总碱度(HCO-3+CO23-)在盐渍土中分别降低了0.05～0.20、8～163μS.cm-1、10.35%～47.74%、12.07%～51.69%、3.39%～40.67%和20.18%～48.56%;Mg2+、Ca2+和SO24-的含量分别增加了3.06%～13.54%、15.58%～56.20%和12.24%～76.12%。结论:改良剂与石膏配施效果比单施改良剂好,其中腐殖酸与石膏配施的改良效果最佳。

| Abstract: | According to the characteristics of coastal saline soil,the effects on ion composition after four alkali-saline soil amendments applyed individually and in combination with gypsum in saline soil were studied out.The results were as follows.The ion composition varied in different degree changes in 0-40 cm soil layer.The pH value,electric conductivity,Na+,K+,Cl-and total alkalinity(HCO-3+CO2-3)in saline soil decreased by 0.05-0.20,8-163 μS·cm-1,10.35%-47.74%,12.07%-51.69%,3.39%-40.67% and 20.18%-48.56%,respectively.The content of Mg2+,Ca2+ and SO2-4 increased by 3.06%-13.54%,15.58%-56.20% and 12.24%-76.12%,respectively.The conclusion was that the application of alkali-saline soil amendments combined with gypsum was better than that of single.The best way to improve coastal saline soil was humic acid application combined with gypsum. |
