| 摘 要： | 由于饲料添加剂的使用,猪粪重金属污染已非常普遍,尤其是铜(Cu)、锌(Zn)污染最为明显.为了探讨利用蚯蚓萃取猪粪重金属Cu、Zn从而减少猪粪中重金属Cu、Zn含量的技术途径,采用室内接种法研究了赤子爱胜蚓(Eisenia foetida)对猪粪重金属Cu、Zn的吸收及影响因素.结果表明,蚯蚓对猪粪重金属Cu、Zn具有一定的吸收能力,富集系数分别为0.43、0.73;物料C/N比、温度、湿度和蚯蚓接种密度均能影响蚯蚓对猪粪重金属Cu、Zn的吸收,在物料C/N比为17:1～22:1、温度为14～21℃、湿度为70%～75%、接种密度为10～20尾·200 g-1物料(2.4～5.0 g·200 g-1物料)条件下,蚯蚓对Cu、Zn的吸收量较高.

| Abstract: | Use of additives containing heavy metal in animal feeds and heavy metals (e.g. Cu and Zn) in pig manure is ubiquitous causing a serious pollution hazard. It is assumed that earthworm acts like a bioreactor that likely removes heavy metal from pig manure. However, limited information is available on the heavy metal extracting ability of earthworms. The objective of this study was to assess the effect of earthworm presence on Cu and Zn uptake from pig manure and its influencing factors such as C/N ratio, temp... |
