| 摘 要： | 采用田间小区试验,研究了土壤改碱剂CLS对吉林省西部苏打盐碱土的改良效果。结果表明:重碱土施用改碱剂CLS后,土壤物理性质得到了明显改善,土壤容重呈现逐渐下降的趋势,孔隙度则呈现逐渐增加的趋势;土壤化学性质的变化表现为pH值、总碱度、交换性钠等指标下降较大,但对阳离子交换量没有显著的影响。说明改碱剂CLS对土壤的综合改良效果较好,适用于重度盐碱土的改良。

| Abstract: | To improve the serious alkali soils in western Jilin province,the effect of the soil conditioner CLS on serious alkali soils was studied by field experiment.The result showed that the application of CLS could decrease bulk density and increase soil porosity.And it decreased the value of pH,total alkalinity and exchangeable sodium,but the CEC was not obviously changed. The research showed that CLS is fit for alkali soil improvement. |
