The contents of K, Ca and Mg in 76 blueberries are determined by Microwave Diges-tion—Atomic Absorption Spectrum ( AAS) method. The experimental results indicate that,the K, Ca and Mg contents were 0. 093 % ~5. 06 %, 0. 131 % ~0. 826 % and 0. 048 % ~0. 246 % in 95% of blueberries, respectively. In addition , this method exhibited spike recov-eries for 3 mineral elements were 96 . 23% ~102 . 03% and RSDs of sample results were 0 ~9. 07%, with good accuracy and precision.
