摘要
对东北农牧交错带内具有代表性的某草甸土壤、2种小尾寒羊主食牧草、放牧小尾寒羊被毛及肝脏中铜含量进行了分析,结果表明:该交错带草甸土壤中铜的总平均含量为8.58μg／g;2种小尾寒羊主食牧草中铜的总平均含量为9.60μg／g;放牧小尾寒羊被毛中铜的总平均含量为5.53μg／g,肝脏中铜的总平均含量为86.17μg／g。2002年,该交错带放牧小尾寒羊当年没有发生铜缺乏症和铜中毒病。
Copper contents of soil , 2 kinds of herbages preferred by codetta , and of wool and liver of codettas were determined in northeast farming - grazing enterlocking district in May , July and Novtember, 2002 . The results showed that , in this district , the total average content of copper in soil of meadow , 2 kinds of mainly grazed herbage , wool and liver of grazed codettas is 8. 58 ug/g , 9.60 ug/g , 5.53 ug/g and 86.17 ug/g respectively .
