| 摘 要： | 对云南省巍山、洱源等9个县(市)的土壤pH、阳离子交换量(CEC)及土壤和饲料样品的钴、铁和硒元素含量进行测定。结果表明:在中性至酸性范围内,土壤中钴、铁和硒元素含量随酸性增强和土壤保肥力的提高而升高;在土壤pH 5～6范围内,饲料样品中钴和铁的含量最高,饲用植物在该pH值范围内对钴和铁元素的吸收能力最强,而饲料样品中硒含量随着土壤pH值升高而逐渐增加

| Abstract: | Determination on pH and cation exchange content (CEC) of soil and Co,Fe and Se content in soil and forage samples from 9 countries in Yunnan province showed that the contents of Co, Fe and Se in soil increased as the increasing of acidity and keeping fertility in the range of neutral to acid. The contents of Co and Fe in forage samples were highest in the range of pH from 5 to 6. The absorbing ability of forage plant to Co and Fe was highest under the condition of acid, whereas the content of Se in forage samples increased as the increasing of pH in soil. |
