| 摘 要： | 通过田间试验初步探讨了污泥对花生产质量、土壤肥力以及花生与土壤重金属元素含量的影响。结果表明,每公顷施污泥7500￣30000kg比不施花生产量增加6.3%￣15.8%,且随着污泥用量的增加花生产量增加。污泥对改善花生品质,保持和提高土壤肥力具有作用。施用污泥处理花生和土壤重金属元素含量与不施污泥的没有明显差异,说明施用污泥不会产生重金属元素对作物和土壤的污染。

| Abstract: | A field trial was carried out to study the influence of sludge application on yield and quality of peanut, soil fertility and heavy metal content in soil and peanut. The result showed that applying sludge 7500~3000kg/hm2 could increase the yield of peanut by 6.3%~15.8% based on no sludge application, and the yield of peanut increased as the sludge application rates increased. Applying sludge had positive effect on improving the quality of peanut, keeping and improving soil fertility. According to analysis of the heavy metal content in soil and peanut, there was no obvious difference between sludge application treatment and no sludge treatment. That indicated that the crop and soil were not polluted by heavy metal in sludge application. |
