摘要： The effect of pH on available Cd in calcareous soils and culture substrate was studied by adding exogenous Cd and artificially adjusting the pH to create different pH conditions. It is expected to provide reference for the control of Cd pollution by adjusting pH. The cadmium chloride was added to the calcareous soil and culture substrate to make the total cadmium content 1.0 mg kg(-1). The pH of soil and substrate was adjusted, and then the available cadmium content in soil and cultivation substrate was detected under different pH conditions. The content of available Cd in calcareous soil decreased with increasing pH in the range of pH 3.40 to 8.97, showing a significant negative correlation. At a pH range of 3.03 to 4.37, the available Cd content in the culture substrate increased significantly with increasing pH, while the available Cd content in the culture substrate at a pH range of 4.37 to 9.47 was not significantly different.
