| 摘 要： | 论文测定了陕西关中地区塿土紫花苜蓿（Medicago sativa- Linn.）、白三叶(Trifolium repens- Linn.)、菊苣(Cichorium endivia- Linn.)、大麦(Hordeum vulgare Linn.)和无芒雀麦(Bromus inermis-Leyss.)地上部与根部铅、铬、锌、铜、铁、锰5种重金属元素的含量，评价了参试牧草对各种重金属的转运能力和饲草的安全性。结果表明：（1）5种牧草根部对所测六种重金属元素的吸收转运能力不同，对铅、铁、锰、锌、铜、铬的吸收能力有禾本科强于豆科的趋势；（2）白三叶对于铁，铜和菊苣对于猛、锌、铜的转运系数大于1，分别为1.70、2.55、1.57，属富积型植物；（3）菊苣的铅含量与种牧草的铬含量均已超过饲料标准；菊苣和大麦作为人类的蔬菜和粮食均已超过相应标准，但作为饲料基本接近相应标准。

| Abstract: | The alfalfa(Medicago sativa Linn.),white clover(Trifolium repens Linn.),chicory(Cichorium endivia Linn.),barley(Hordeum vulgare Linn.) and smooth bromegrass(Bromus inermis Leyss.) in Guanzhong plain were selected to determine the heavy metal content of lead,iron,manganeses,zinc,copper and chromium in shoots and roots of the five forages so as to assess the transfer capacity of heavy metal and the security of the forage.The results showed that:(1) there were differences among 6 heavy metal contents in 5 forages and there was a trend that the grasses are stronger than the legumes in absorption capacity of lead,iron,manganeses,zinc,copper and chromium.(2) The transfer coefficients of white clover to iron,copper and chicory in manganeses,zinc and copper were bigger than 1,which were 1.70,2.55 and 1.57 respectively,and it belongs to cumulative type.(3)The lead content of chicory and chromium content of five forages exceeded the standards for feeds;if chicory was used as a vegetable or barley as food grain,both of them did not meet the permitted amount of heavy metals,but if used as feed materials,they approached basically the corresponding standards. |
