浙江红壤和黄壤的电荷特性

Charge Characteristics of Some Red and Yellow Soils in Zhejiang Province

本文对浙江省红壤和黄壤的电荷特性作了初步研究。结果表明，黄壤的可变负电荷量、正电荷量、有效阳离子交换量（ＥＣＥＣ）和可变电荷零点（ＰＨ０）都高于红壤。红壤和黄壤可变负电荷量占负电荷总量的半数以上。土壤的电荷特性与活性铁铝氧化物密切相关。

This paper presents charge characteristics of some red and yellow soils in Zhejiang province. Results show that amount of variable charge and positive charge,effective canon exchangeable capacity, zero point of charge in yellow soils are higher than that in red soils. Amount of variable charge in red and yellow soils is more thanhalf of the total charge. Significant correlation has be found between charge characteristics and active iron and aluminium oxides.
