Abstract:
The region of Aksu is the major cultivation area of Xinjiang Fuji apple in Southern Xinjiang region.Six trace elements in Fuji apple were determined using atomic absorption to compare the effects of different water-nitrogen treatments on trace element contents of Fuji apple.The results show that increased nitrogen improved contents of Ca,Mg,and Zn under moderate water condition.Moderate irrigation and fertilizer maintained high Fe level.Excessive or insufficient irrigation and fertilizer undermined the accumulation of mineral Fe in apple fruits.The contents Cu and Mn related positively to the application amounts of nitrogen.
