摘要
对湖南省株洲市、桃源县和蓝山县等3处的油茶林红壤的物理化学性质进行了研究。结果表明,这些土壤的特点是:酸性强、有机质含量不高;除总钾以外,总氮和总磷含量不高;交换性阳离子含量低,而CEC(阳离子交换吸附容量)数值不小。这些土壤地力不高,但适于油茶生长。
Physical and chemical properties of 3 types of red soil in the oil-tea camellia woods of Hunan, China were studied. The results indicated that the characteristics of soils are strongly acidic, the content of organic matter is low; expect for total K, total N and total P are slightly contained; the content of exchangeable cation is low; but the value of CEC is high. The pollution of heavy metals (for example, Cu, Zn, Cd and Pb) do not exist. The soil fertility of red soils is low, but they are suitable for the oil-tea camellia to grow.
