摘要：

采用大田试验 ,研究了施用脱硫废弃物对枸杞生长及重金属含量的影响。结果表明:脱硫废弃物的施用能有效提高枸杞的发芽率和存活率，且不同处理之间差异显著(P＜0.05)。 1.0吨/亩的处理效果优于2.0吨/亩，其发芽率达到81.5%，成活率达到80.8%。处理后土壤都没有超过国家《土壤环境质量标准》G B15618— 1995年规定的二级土壤使用标准；对枸杞果和叶重金属含量也均符合国家标准《食品中污染物限量》GB2762-2005的规定，可见利用脱硫废弃物改良盐碱土是安全可靠的。

Abstract:

A field experiment was conducted to study the effect of By-product of Flue Gas Desulphurization(BFGD) application on Wolfberry’s growth and Heavy Metals Concentration. The results showed that:Applying BFGD can effectively improve the germination and survival rate of Wolfberry,the effect of 1.0 ton/acre is better than 2.0 ton/acre,the germination was 81.5%,the survival rate reached 80.8%. The content of heavy metals in soils did not exceed the secondary standard of “soil environmental quality standard”,GB156-1995year;The contents of heavy metals of Wolfberry’s fruit and leaf in each treatment also are in line with the national standard of“contaminants in food limited”,GB2762-2005.so we can concluded that use BFGD to ameliorating saline-sodic soil is safe and feasible.
