摘　　要：研究了草炭的不同分解产物(水溶性和非水溶性)对棕壤铜、锌吸附作用的影响。结果表明:在一定的pH范围内,草炭水溶性分解产物均不同程度地抑制了铜、锌的吸附,而非水溶性分解产物促进了铜、锌的吸附。吸附等温线试验表明,在不调节pH值的条件下,水溶性和非水溶性分解产物及不同水分条件培养后的分解产物均促进了对铜、锌的吸附。We studied the effects of decomposed products of grass charcoal on the adsorption of Cu and Zn. In certain range of pH, soluble decomposed products restrained the adsorption of Cu and Zn, however, insoluble decomposed products promoted the adsorption of Cu and Zn. The adsorption isothermals of Cu and Zn indicated that if the pH values of the soil was increased for the decomposition products of grass charcoal, the soluble and insoluble decomposition products all promoted the adsorption of Cu and Zn.
