In order to solve the problem of low efficiency in the detection and analysis process of organic fertilizer,this paper proposes an efficient method for the determination of potassium content in organic fertilizer for tobacco use by setting up a joint detection platform of continuous flow analyzer and flame photometer.Moreover,orthogonal experiments are used to optimize the parameters of the experiment process and determine the best conditions for sample processing and pipeline configuration.The results showed that the absolute difference of the method was less than 0.01％compared with the standard method,which met the need of rapid and accurate determination of potas-sium in tobacco fertilizer.
