通过对烟气脱硫废弃物改良河套地区盐碱土壤的田间试验研究,结果表明:施用烟气脱硫废弃物对盐碱土壤具有明显的改良效果,盐碱土壤的理化性状有所改善,向日葵的产量大幅增加;烟气脱硫废弃物的施用量以1.76t/hm2改良效果最为明显。
The results showed that the flue gas desulfurization wastes had a significant improvement effect on saline-alkali soil, the physical and chemical properties of saline-alkali soil improved, and the yield of sunflower A substantial increase; flue gas desulfurization waste to 1.76t / hm2 to improve the effect of the most obvious.
