摘要:
为了探究碱化土壤的改良，采用田间试验方法，研究脱硫石膏改良碱化土壤盐分组成变化情况。结果表明：改良前后土壤的pH明显下降，碱化度下降幅度也比较大。Na+、CO2-3和HCO-3明显下降，Ca2+、Mg2+和SO2-4明显上升，Cl-变化不大；土壤中的Na+被Ca2+代换，CO2-3、HCO-3被SO2-4代换，大大降低了土壤的碱化度，改良后的土地种植玉米，虽然单产相对正常的还较低，但其生态价值远远高于未经改良的土地。
Abstract:
In order to explore the improement of alkaline soil,the method of field experiment was used,the composition change of desulfurization gypsum improving alkaline soil salt was studied.The results showed that before and after the improvement,pH and alkalization degree of soil decreased obviously.Na+,CO2-3,HCO-3 declined obviously,Ca2+,Mg2+,SO2-4rised obviously.Na+ from the soil was taken place by Ca2+,CO2-3,HCO-3 were taken place by SO2-4,that reduced the soil alkalization degree, although the yield of maize in soil which was improved was lower than normal,but its ecological value was significantly higher than that without the improvement of land.
