中文摘要:

为研究在发酵床养猪过程中不同组成垫料的As、Hg累积规律，本文以木屑、稻壳和秸秆为原料，配制成3种垫料处理，分别为木屑（S）、木屑+稻壳（SR）和木屑+稻壳+秸秆段（SRS），在一年半的时间里，测定了4批育肥猪养殖结束时不同层次垫料中As、Hg含量，分析了长期使用后不同发酵床垫料中As、Hg累积情况，为发酵床废弃垫料的后续农用提供理论依据。结果表明，随着猪养殖批次的延长，3种处理及其不同层次垫料As、Hg含量均存在不同程度增加。4批猪养殖结束时，As累积量最大的是SRS处理的发酵床，为1921.7 mg·栏^-1，Hg累积量最大的也是SRS处理的发酵床，为21.1 mg·栏^-1。S、SR、SRS处理的As、Hg含量分别为2.921、2.190、2.621 mg·kg^-1和0.048、0.036、0.042 mg·kg^-1，均符合《农业行业标准有机肥料》（NY 525-2012）、《食用农产品产地环境质量评价标准》（HJ/T 332-2006）的标准限值。

英文摘要:

In order to study the accumulation and distribution of As, Hg in different bio-bed padding materials while implementing bio-bed raising method, three kinds of bio-bed padding materials were well designed, which consisted of sawdust(S), sawdust + rice husk(SR) and sawdust + rice husk + straw(SRS). For a year and a half, the contents of As, Hg at different depth were measured when four groups of fattening pig breeding had finished to analyze the accumulation and distribution of As, Hg in different bio-bed padding materials, which could provide a theoretical basis for follow-up application of bio-bed padding materials in agriculture. The results showed that, the accumulation of As and Hg, at different levels, occurred during four pig-raising cycles. When 4 groups of fattening pig breeding finished, the largest accumulation of As and Hg occurred in SRS bio-beds, respectively reached 1921.7 mg per sty and 21.1 mg per sty. The As and Hg contents of S, SR,SRS were 2.921, 2.190, 2.621 mg·kg^-1 and 0.048, 0.036, 0.042 mg·kg^-1, respectively, which met the China's Organic Fertilizer Agriculture Standards(NY 525-2012), and Farmland Environmental Quality Evaluation Standards For Edible Agricultural Products(HJ/T 332-2006).
