摘  要:
研究了不同施肥处理的蔬菜保护地土壤磷的吸附特性。结果表明:化学氮钾肥与磷肥配施对土壤吸附磷素有显著的影响,氮磷钾肥配施能够最大程度地降低土壤对磷的吸附作用。Freundlich方程对各不同施肥处理土壤的等温吸附数据拟合程度要好于Langmuir和Temkin方程,为最优模型。

摘  要:
The characteristics of phosphorus absorption in soil under the condition of different fertilizations was studied.The results showed that the compound fertilizer of N-K and P had an distinctly effect on phosphorus absorption in soil,and the application of compound fertilizer could decrease the adsorption of phosphorus.Freundlich in application of the evaluation of fertilizer in soilequation was better than the other two equations.
