摘  要:
3种土壤对5种元素的吸附特性研究结果表明:在所取的3种土壤中,黑土吸附N、P、K的能力较弱;白浆土吸附N、B的能力最强;盐碱土吸附P、Zn的能力最强。根据土壤养分吸附曲线,可以方便地确定各元素的施用量,以指导科学施肥。

摘  要:
An experiment was conducted for the characteristics of N,P,K and Zn adsorbed by three typical soil, the results shown that capacity of N,P,K of adsorption was weaker on black soil than the rest of soil; It was strong for albic soil to adsorb N, B in three kinds of soil;Saline-alkali soil was stronger than other to adsorb P and Zn.We can determine fertilizer index and apply fertilizer scientifically through soil nutrient adsorption curve.
