【摘要】 根据对安徽省40个县(市)所采集的441份饲料样品进行硒含量测定表明,玉米等16种主要饲料硒含量变动幅度为0.016～0.075PPm;其中以大豆硒含量最高,甘薯干硒含量最低。按饲料硒含量地理地域分布计算(以PPm计),以沿江平原饲料硒平均含量最高(0.061±0.032),其次依序为江淮丘陵(0.046±0.015)、淮北平原(0.043±0.012)、皖南山区(0.037±0.014),而以皖西大别山区饲料硒平均含量最低(0.029±0.013)。按饲料硒含量政区分布计算,硒平均含量≤0.024ppm的县(市)占5%,0.025～0.054ppm—77.5%,≥0.55ppm—17.5%。更多还原

【Abstract】 There are wide areas in AnHui Province where most grains and forages are low in selenium in terms of animal needs. These areas are located in the regions of Dabi mountain(0.029+0.013ppm),Southern mountainour regionr (0.037+O.014ppm), Northern plain(0.043+0.012ppm), and Hills between Yangtse river and Huai river (0.046+O.015ppm) .更多还原
