本文着重介绍海南农垦地区土壤的微量元素现状。比较了不同土类、不同母质土壤的 Ca、Mg 以及 Cu、Zn、Mn、Mo、B 的含量水平,及其在不同类型土壤土层中的分布,并分析了几种微量元素的有效量与全量及有机质的关系。调查结果表明:海南垦区土壤 Ca 含量都很低;某些砂性土缺 Mg;Cu、Mn 皆较丰富,部分土壤缺Zn 和 Mo,而大部分土壤缺 B,水田缺 B 尤为普遍。
This article focuses on the status of soil trace elements in Hainan reclamation area. The contents of Ca, Mg, Cu, Zn, Mn, Mo and B in different soils and different parent materials were compared and their distribution in different types of soils and soils were analyzed. The effects of several trace elements Total amount and organic matter. The results showed that the content of Ca in soils in Hainan reclamation area was very low. Some of the sandy soil was lack of Mg, rich in Cu and Mn, and some of the soil was deficient in Zn and Mo, while most of the soil lacked B and B was especially common in paddy fields.
