摘    要:通过石灰性和酸性土壤施用鸡粪和猪粪并预培养不同时间,采用生物盆栽试验方法研究了不同畜禽粪便有机肥中重金属的生物有效性差异及其随培养时间的动态变化。试验结果表明,石灰性和酸性土壤上施用鸡粪和猪粪后6个月内,鸡粪和猪粪中Cu、Zn、Cd的生物有效性显著低于等量重金属无机盐或与之相当。鸡粪中Pb的生物有效性也显著低于等量Pb无机盐,猪粪中Pb的生物有效性前5个月显著低于等量Pb无机盐,6个月时则显著高于等量Pb无机盐。2种土壤施用鸡粪和猪粪后的不同时间段,畜禽粪便有机肥中Cu、Zn、Cd、Pb的生物有效性也存在显著性差异;在施用后6个月内呈现先下降后上升的规律,施用后2个月时生物有效性最低,为等量相应重金属无机盐的3.4%~47%。

关 键 词:畜禽粪便  重金属  生物有效性

Abstract:In this study, chicken manure and pig manure were applied to calcareous and acid soils to investigate the bioavailability dynamics of heavy metals in manure after 0, 1, 2, 4, and 6 months. The results showed that the concentrations of heavy metals in Chinese cabbage treated with the manure were lower than those with same amount of inorganic salts of heavy metals. The bioavailability of Cu, Zn, and Cd in both manures and Pb in chicken manure was less than that of inorganic salts of heavy metals with same amount within 0~6 months, whereas Pb in pig manure was less than that of the inorganic salt in 0~5 months but greater in 6th month. The dynamics of metal bioavailability over time showed similar trend in both soil types. The heavy metals in Chinese cabbages displayed initial decrease then increase with culture time and were the lowest in 2 months after application. The concentrations of Cu, Zn, Cd and Pb in Chinese cabbage in organic manure were 3.4%~47% of those in heavy metal inorganic salts.
Keywords:pig and chicken manure  heavy metals  bioavailability
