摘　　要：以工业废渣—脱硫渣农业资源化利用为切入点,结合传统的盐碱地改良措施,通过田间小区试验研究盐碱地4种改良措施对盐荒地的改良效果,评价了单项措施和组合措施的效应。结果表明,盐碱地4种改良措施中,洗盐措施对0~40 cm土层的土壤脱盐效果明显优于其他3种措施,施用脱硫渣结合洗盐对盐荒地土壤改良效果明显,深松和施肥措施对提高油葵出苗率可起到促进作用。Taking industrial waste residues-desulfuration residue as the starting point,combining with traditional improved measures of saline-alkali soil,the improved effects of four improved measures of saline-alkali soil on salt wasteland were studied,and the effects of a single meaure and combination of measures were evaluated by the field plot experiment,the results showed that among the four measures in improved technologies of saline-alkali soil,the salt-leaching measure was clearly superior to the other three measures in soil desalting effect of 0-40 cm soil layer.Applying desulfuration residue in combination with salt-leaching measures had an obvious improving effect on salt wasteland.Deep digging and applying fertilizer helped oil sunflower germination rate.
