磷活化剂对红壤吸磷特性的影响

Effects of Phosphorus Activator on Absorbability of Phosphorus in Red Soil

    摘要
  • 摘要: 为了解磷活化剂对红壤吸附外源磷的影响，探讨沸石、腐殖酸、柠檬酸、草酸铵对红壤吸磷特性的影响。结果表明：腐殖酸、柠檬酸、草酸铵可有效降低红壤对磷的吸附能力，加腐殖酸使红壤的吸附量降低了902%~11.75%，加柠檬酸使红壤的吸附量降低了1742%~21.74%，加草酸铵使红壤的吸附量降低了987%~3610%。沸石增强了红壤对磷的吸附能力，吸附量增加了11.04%~1754%，吸附率提高了954%~1708%。

     

    Abstract: The effect of zeolite (Ze), humic acid (HA), citric acid (CA) and ammonium oxalate (AO), on absorbability of phosphorus in red soil was studied in order to understand the influence of phosphorus activator on absorbability of external phosphorus resource. The results showed that HA, CA and AO could effectively reduce the absorption and fixation of phosphorus by the red soil. The capacity of phosphorus absorbability by the red soil was reduced by 902%-11.75%, 1742%-21.74%, and 987%-3610% respectively by adding HA, CA and AO into the red soil. It was showed that Ze would increase phosphorus absorption amount by 11.04%-1754%, and promote phosphorus adsorption rate by 954%-1708%.
