摘  要：
通过大田对比试验,研究施用脱硫废弃物种植国槐后,土壤理化性质的变化及其对国槐生长的影响,同时监测土壤及地下水的As及重金属含量,以期为宁夏盐碱地绿化造林提供安全有效的技术措施。结果表明,施用脱硫废弃物可明显降低土壤pH值、全盐含量、碱化度,施用3a后其分别较未施用脱硫废弃物处理降低17.20%、47.02%、37.55%;施用脱硫废弃物可显著提高国槐成活率,施用3a后国槐成活率达83.33%,较未施用脱硫废弃物处理显著提高了42.86%;施用脱硫废弃物3a后土壤和地下水As、Hg、Pb、Cr、Cd含量均低于国家标准规定的允许值。可见,利用脱硫废弃物改良盐碱地并进行绿化造林既行之有效,又安全可靠。

摘  要：
The field experiment of planting Sophora japonica L.was carried out to study the effect of desulfurization waste on soil physical and chemical properties,growth of Sophora japonica L.and content of As and heavy metal in soil and groundwater.The results showed that the application of desulfurization waste decreased the pH value,total salt quantity and exchangeable sodium percentage(ESP)of soil,when the desulfurization waste was applied for three years,the above indexes decreased by 17.20%,47.02% and 37.55% respectively compared with the treatment without desulfurization waste(control);the application of desulfurization waste increased the survival rate of Sophora japonica L.,which was 83.33% when the desulfurization waste was applied for three years,42.86% higher than the control;the concentration of As,Hg, Pb,Cr,Cd in soil and groundwater were below the national standard when the desulfurization waste was applied for three years.So the desulfurization waste used for ameliorating saline-alkali soil was effective and safe.
