摘要： Effect of peat on cadmium content in soil morphology, cabbage growth and cadmium content and ecological characteristics of the microbial using Cd-contaminated vegetable plot is investigated. The results showed that the pH of soil can be significantly improved and effective Cd content in soil can be reduced after peat was added. Lasting effect remains significant although three crops of cabbage were continuously planted. The application of peat, continuous planting cabbage compared with the control can significantly increase the biomass and decrease the Cd content in shoots. Continuous planting of three crop of cabbage and the content of Cd increased, but were lower than the limited value in GB2762-2012. Peat can increase the activity of microorganisms in soil, peat and plant with more obvious effect on the increase in microbial activity in soil. The ability to increase can promote Chinese cabbage growth and inhibit the absorption of Cd by polymers, carbohydrates, carboxylic acids, amino acids and other carbon sources.
