摘要:

采用《水溶肥料 腐植酸含量的测定》(NY/T 1971—2010)检测水溶肥料中的腐殖酸含量,具有操作简单、重现性好等优点,但存在平行样结果不平行且不能达到稳定状态的问题。针对存在的问题,通过增加简单的操作步骤,使平行样检测结果达到平行且稳定的状态。

Abstract:

The determination of humic acid content in water-soluble fertilizers by using "Water-soluble fertilizers—Determination of humic-acids content" (NY/T 1971—2010) has the advantages of simple operation and good reproducibility, however, there are some problems, such as the parallel determination results are not parallel and the results are not able to reach a steady state. In connection with the existing problems, by adding simple operation steps, the parallel sample determination results are achieved a parallel and stable state.
