| 摘 要： | 硒是人和动物必需的微量元素之一。土壤中的硒含量过多或过低，人和 动物都会出现地方性疾病。土壤中硒的含量与土壤母质、地形、气候条件和土壤条件性质等有关，调节土壤性质可以改善作物的含硒量。防治硒缺额症和硒中毒症，每天必需摄入适量的硒，以100－200μg为宜，但人体对硒的需要量也与食物成分有关。

| Abstract: | Selenium is an important trace element which is essential to animals and human being.It may cause diseases when its content in soils and plants goes beyond or goes below the normal level.The content of selenium in soils is controlled by a series of factors,such as soil parent material,soil forming process,soil property and climate,etc.Adjusting the pH vallue and Eh value of soil can improve the content of selenium in crops. |
