| 通过盆栽试验,研究了燃煤烟气脱硫废弃物和糠醛渣对盐碱土的改良效应。结果表明:施入燃煤烟气脱硫废弃物和糠醛渣后的盐碱土,土壤pH值、可溶性盐和碱化度(ESP)均有不同程度降低,以燃煤烟气脱硫废弃物和糠醛渣配合施用改良效果最为明显,土壤pH值、可溶性盐和碱化度(ESP)分别由初始的9.2、10.71‰和25.97%下降到7.5、9.43‰和9.52%;油葵的出苗率高达68.3%,明显比对照高出60%,差异达显著水平。 |

| A pot experiment was conducted to study the effect of by-product of flue gas desulphurization （BFGD） and furfural residue on ameliorating saline-sodic soil．The results showed that：pH sobuble salts and the exchangeable sodium percentage （ESP） were decreased at different degrees by applying the BFGD and furfural residue but most obvious effect was made by applying the BFGD and furfural residue at the same time and pH soluble salts and ESP from the initial9．2 10．71‰ and 25．97％ went down to 7．5 9．43‰ and 9．52％；Sunflower germination rate was as high as68．3％ 60％ higher than that of the control. |
