摘要
本文通过实验,运用常规方法和速效方法来测定土壤中的有效氮、磷、钾等元素含量,并将两种测定方法结果对比分析,通过作图法来得出两者之间的相关性。
In this paper,conventional methods and quick-acting methods are used to determine the content of available nitrogen,phosphorus,potassium and other elements in the soil,and the results of the two methods are compared and analyzed.The correlation between the two methods is obtained through the mapping method.
