摘要
简要概述了土壤钾素的形态、不同形态钾的有效性、钾在土壤中的转化、不同耕作方式对土壤钾素的影响,指出了不同钾素形态之间的转化速率是影响土壤供钾能力的主要因素,今后应该加强不同耕作方式下土壤钾素转化动力学以及耕作方式对土壤钾素固定的影响及其机理研究。
The soil potassium forms, effectiveness of different forms of potassium, transformation of potassium in the soil and the influence of different tillage methods on soil potassium were briefly summarized in the paper. It was pointed out that the conversion rate between different forms of potassium was the main factor affecting the availability of soil potassium. In the future, the transformation of soil potassium dynamics under different farming methods and the influence of farming practices on soil potassium fixation and mecha- nism research should be strengthened.
