- 摘要:
- 为更好的合理、安全利用沼渣，以豇豆为试材，研究了猪粪、沼渣、猪粪和沼渣混配为底肥对豇豆产量、豇豆可食用部分和土壤重金属积累的影响，其中，设置对照（CK，不施肥），沼渣1（667 m2施1 000 kg沼渣），沼渣2（667 m2施1 500 kg沼渣），沼渣3（667 m2施2 000 kg沼渣），沼渣+猪粪组（667 m2施1 000 kg沼渣+1 000 kg猪粪），猪粪组（667 m2施2 000 kg猪粪）。结果表明：与不施肥相比，各处理产量均比对照显著增加，667 m2对照产量为220.29 kg，而沼渣1、沼渣2、沼渣3、猪粪和猪粪与沼渣混配的产量分别为689.85、921.55、1 062.08、950.54、1 354.91 kg，较对照分别增加213.16%、318.33%、382.13%、331.49%和515.07%。收获后，豇豆可食用部分重金属含量均低于国家标准（GB 2762-2012）规定的含量。土壤中重金属含量是沼渣施用量较大时重金属含量较高，而且有些重金属含量超过了国家限量标准，如施用量大的沼渣3后土壤中的Pb含量为69.902 mg?kg-1，较种植前土壤Pb含量增加385.667%，且其含量超过了国家一级标准35 mg?kg-1，较高沼渣施用量引起了土壤重金属污染风险。
- Abstract:
- To achieve rational and safe use of biogas residue,a field experiment was carried out to study the effects of the biogas residues on the yield of cowpea and heavy metal accumulation in cowpea and soil.Different treatment combinations were set,i.e.,control （CK,without applying any fertilizer),group 1 of biogas residues （applying biogas residue at 1 000 kg per 667 m2),group 2 of biogas residues （applying biogas residue at 1 500 kg per 667 m2),group 3 of biogas residues （applying biogas residue at 2 000 kg per 667 m2),group of mixture of biogas residues and pig manure （applying biogas residue at 1 000 kg plus pig manure at 1 000 kg per 667 m2),pig manure （applying pig manure at 2 000 kg per 667 m2).The results showed the yield of each treatment was higher than that of control （CK).The yield were 689.85,921.55,1062.08,950.54,1 354.91 kg per 667 m2 for group 1 of biogas residues,group 2 of biogas residue,group 3 of biogas residues,group of pig manure,group of mixture of biogas residues and pig manure,and increased by 213.16%,318.33%,382.13%,331.49% and 515.07% compared with the yield of group of CK （220.29 kg per 667 m2),respectively.After harvest,the heavy metal in the edible cowpea was lower than the value of the National Standards （GB 2762-2012).But the content of some heavy metals in soil were higher and above the range of the National Standards of the soil with higher application amount of biogas residues.The content of Pb was 69.902 mg?kg-1 in soil with application of group 3 of biogas residues,was increased by 385.667% compared with the content before planting,and the content was above the range of the National Primary Standard （35 mg?kg-1) of the soil.Higher application of biogas residues caused rise of heavy metal in soil．
