原始语种摘要: To clarify the effects and the application value of biochar on remediation of cadmium (Cd)-contaminated soil, a pot experiment was conducted with the typical farmland soil suffering from Cd-contamination derived from the contaminated irrigation area at countryside of Shenyang in China.The results showed that maize-straw-derived biochar which used dry distillation of carbonization technology under deficient oxygen and low temperature (400-450℃) had well characteristic of structure and physical and chemical properties.It could reduce the available cadmium ion enrichment of Cd-contaminated soil to a certain extent that with the "passivation or inhibitory" effect related the time-lapse. The Soil pH had fluctuation for the biochar amendment, but did not appear the "continuously higher or...
