| 摘 要： | 新疆自治区南部阿克苏地区是新疆红富士苹果的主要产区。以该区红富士苹果为对象,设置不同水氮处理,利用原子吸收法测定了果实中6种矿质元素的含量,分析了不同施肥、灌溉水平对各矿质元素含量的影响。结果表明,灌水适中条件下增施氮肥量可以提高苹果果实中Ca,Mg,Zn的含量;适度的灌水量和氮肥供应能维持Fe元素含量保持较高的水平,灌水量和氮肥供应过高、过低均不利于苹果果实中矿质Fe的积累。Cu和Mn含量与氮肥施用量呈正相关关系。

| 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. |
