摘要
以肥料定位试验为基础,比较了污泥肥、生活垃圾肥和常见农用肥料(化肥、鸡粪肥)农田施用下土壤和作物籽粒、秸秆中Cd、Cr、Pb、Hg、As、Cu、Zn、和Ni八种重金属的积累以及作物产量的变化情况,用来阐明污泥肥和生活垃圾肥施用对土壤和作物籽粒以及产量的动态影响规律。研究表明,与化肥和鸡粪肥分别比较,施用生活垃圾肥可以显著带来作物的增产,而污泥肥处理作物增产效果不明显;根据国家粮食卫生标准(GB 2715-2005)、MPCC以及《食品卫生标准》(GB2762-2005)的规定,施用污泥肥和生活垃圾肥处理的作物籽粒重金属含量均在其标准限量值范围之内,完全符合安全标准;污泥肥和生活垃圾肥比化肥、鸡粪显著增加了土壤Cr和Hg含量。所有处理的土壤重金属含量均在土壤环境质量一级标准(GB15618-1995)的重金属限量值(pH>7.5)范围内。
Based on a located experiment,by comparison of eight heavy metals＇ contents of Cd,Cr,Pb,Hg,As,Cu,Zn and Ni between soil and crop seeds,as well as crop yields among different fertilizer treatments of sludge,domestic waste and ordinary agricultural materials（chemical fertilizer and chicken manure）,the effects of sludge and domestic fertilizers on the soil and plant＇ seed and production were elucidated.The results indicated that application of domestic waste could significantly increase the crop yields,while no significant effect was investigated in the sludge treatment in comparison with ordinary chemical fertilizer.According to the standard of food hygiene（GB 2715-2005）,MPCC and food safety（GB2762-2005）,the mental contents of crop seeds were within the scopes of standard values.Comparing with chemical fertilizer and chicken manure,sludge and solid waste fertilizer increased soil Cr and Hg contents obviously.The heavy metal concentrations in all treatments were in the soil environmental quality standard（GB15618-1995） limited value（pH 〉7.5）.
