摘要
在贵州省贵阳市附近喀斯特区选择两种典型的土壤进行采样,并对土样中各种形态的铜进行测试。结果显示在喀斯特地区石灰土中铜的氧化锰结合态铜、无定形氧化铁结合态铜和紧结合有机态铜要比黄壤中相应形态的铜更为活跃,石灰土中可交换态铜为1.520m g/kg;而黄壤中铜的可交换态铜、碳酸盐结合态铜、松结合有机态铜和晶型氧化铁结合态铜比石灰土的活跃,可交换态铜可达5.458m g/kg。
Two kinds of soils are sampled in typical karst region in Guiyang, Guizhou and all kinds of cupreous speciation are determined. The results show that the cuprum speciation combined with manganese oxide, the cuprum combined with ferric oxide and the cuprum tightly combined with organic matter are more active in calcareous soil than that in yellow soil. The exchangable cuprum content in calcareous soil is 1. 520mg/kg and that in yellow soil 5. 458mg/kg. The exchangable cuprum, the cuprum combined with carbonate, the cuprum laxly combined with organic matter and the cuprum combined with crystalloid ferric oxide are corn- paratively active in yellow soil.
