| 摘 要： | 通过对不同深度层次的发酵床垫料、垫料下土壤、发酵床外土壤和传统猪场外的土壤样品进行连续分析测定,比较了不同养殖模式下As的累积状况及对周边环境的影响情况。结果表明:发酵床垫料使用近1年后,As在0~20、20~40 cm垫料层中存在明显的累积,累积量分别达7.5、6.7 mg·kg-1,存在向垫料下层土壤迁移的风险,且As在垫料下土壤中浓度的增加量高于发酵床外同深度的土壤(P0.05);废弃垫料中As的浓度在11.5~12.0 mg·kg-1之间,符合我国有机肥料农业行业标准,可以适当处理后进行农用;发酵床养殖模式对周边土壤中As累积的影响低于传统养猪模式。

| Abstract: | Increasing use of feeding additives in large scale pig farms has caused environmental and food safety concerns. Here we investigated soil As accumulation under different pig-raising methods. Arsenic concentrations in bio-bed litters and soils below litters(BL), from out of bio-bed(OBB) and from out of traditional pig farm(TPF) were continuously monitored. Significant accumulation of As in litter layers occurred after one year of pig-raising,and As concentration was 7.5 mg·kg-1 and 6.7 mg·kg-1 in 0~20 cm and 20~40 cm layers, respectively. Moreover, As had a potential to move down to 40~80 cm in the soil below litters. The accumulation of As in the BL soils was higher than that in OBB soils(P<0.05). Arsenic concentrations in waste litters varied between 11.5 mg·kg-1 and 12.0 mg·kg-1, which met the China's organic fertilizer agriculture standards. Bio-bed raising mode had less impact on As accumulation in surrounding soils than traditional raising method. |
