麟游县土壤及部分牧草微量元素含量分析

Analysis of Trace Elements Content of Soil and Forage Grass in Linyou County

为了对麟游县肉羊饲料进行合理的调制并进行更科学的饲养管理,在该县5个乡镇分点采集土壤和饲草样品各11份,测定其微量元素和有毒元素含量。结果表明:麟游县土壤中铁、锌、锰含量偏高,平均为10.4 814、1.3 938和24.3 979μg/g;硒、镍和钴含量偏低,平均含量为0.0 523和0.2 989和0.0 543μg/g。土壤有害元素汞、铅、铜含量均在安全范围之内,平均分别为0.1 695、1.1 016和1.0 587μg/g,但砷含量较高,平均为28.9 312μg/g。蒿类植物对各种元素的富集能力都较强,马兰、牛筋草和槐树叶对硒的富集能力较差。

In order to modulate feed reasonably and raise mutton sheep scientifically, 11 soil and forage grass samples were collected to measure trace elements and toxic elements contents. The results indicated that Fe, Zn and Mn contents were high- er, average contents were 10.4 814, 1.3 938 and 24.3 979 μg/g . Se, Ni and Co contents were lower, average contents were 0.0 523, 0.2 989 and 0.0 543 μg/g. Meanwhile, Hg, Pb and Cu contents were in safe range, average contents were 0.1 695, 1.1 016 and 1. 0587 μg/g. However, as content was higher, average content was 28. 9 312 μg/g. Artemisia plants enriches trace minerals strongly, Maran, Goosegrass Herb and locust tree leaf has poor Se enrichment ability.
