脱硫废弃物改良盐碱地对土壤性质的影响

摘要

采用大田试验方法，以盐碱地改良为研究目标，开展了脱硫废弃物改良盐碱地对土壤的影响研究。结果表明：盐碱地施用脱硫废弃物能够显著改善土壤的理化性质，改变土壤的机械组成，土壤的pH和Na++K+/Ca2++Mg2+明显降低，改良效果显著。%The effects of improvement of the saline alkali land with desulfurization waste on soil nature were studied by adopting the field test method and with the improvement of saline and alkaline land as the research target. The results showed that applying the desulfurization waste to saline alkali soil could improve the physical and chemical properties of the soil obviously and change the mechanical composition of the soil. The soil pH value and Na++K+/Ca2++Mg2+ were reduced obviously and the effect of improvement was significant.
