镁、锰、活性炭和石灰对土壤pH及镉有效性的影响
Effect of Magnesium,Manganese,Activated Carbon and Lime on Soil pH and Available Cadmium
摘要
Abstract
An incubation experiment was conducted to investigate soil pH and available cadmium(Cd) as affected by addition of magnesium sulfate(Mg),manganese sulfate(Mn),activated carbon(AC) and lime materials(lime) when applied alone or in combinations.Results showed that Mg,Mn,AC and lime significantly affected soil pH and concentrations of available Cd.Soil pH was remarkably enhanced with addition of lime and positively correlated to its application rates,while soil pH was significantly reduced with addition of Mg,Mn or AC,and negatively correlated to its application rates.No matter these materials were added alone or in combination,concentrations of soil available Cd were reduced or significantly reduced.The effects of these materials on depressing soil available Cd concentrations followed an order of lime Mn 〉Mg 〉AC when applied alone, and an order of lime+Mn+Mg 〉Mn+Mg 〉lime+Mn 〉lime+Mg+Mn 〉lime+AC when used in combinations. The effect of Mg(OH)2 on reducing soil available Cd was superior to Ca(OH)2.关键词
