对分析线、狭缝宽度、燃气流量、燃烧器高度、燃气纯度以及抑制电离剂的加入进行了优化，最终确定在特征谱线波长λ=404.4 nm，狭缝宽n=0.7 nm，燃烧器高度为2 mm，燃气流量为2.2 L/min的条件下，采用火焰原子发射法来测定大量元素水溶肥料中的钾含量，并采用超声振荡的方法确保钾的充分溶解。该方法的准确度和精密度较好，回收率在93.48%～98.71%之间。

The analytic line, the slit width, gas flow rate, burner height and gas purity were optimized as well as the adding of suppression ionization agent, which ultimately determined that in the conditions of the characteristic spectral line wavelength being λ=404.4 nm, slit width being n=0.7 nm, burner height being 2 mm, the gas flow rate being 2.2 L/min, the flame atomic emission spectrometry was used to determine the potassium content of macronutrient water-soluble fertilizer, and the method of ultrasonic vibration was used to ensure the full dissolution of potassium. The accuracy and precision of the method were good, and the recovery rate was 93.48%~98.71%.
