据阿塞拜疆在果树上施用微量元素肥料试验表明：锌肥在甜樱桃上，铜肥在桃树上，锰、锌混合微肥在桃树上都表现明显的增产效果。生物化学分析证明：微量元素对果实的品质（果酸、维生素C、含糖量等）都有显著的提高作用，其中在樱桃上最有效的是锌肥，在桃树上以铜的效果最佳， According to Azerbaijan’s application of trace element fertilizers on fruit trees, experiments showed that zinc fertilizers were applied on sweet cherry and copper fertilizer on peach trees. Manganese and zinc mixed fertilizers showed obvious yield increase on peach trees. Biochemical analysis showed that trace elements have a significant effect on the quality of fruits (such as acid, vitamin C, sugar content, etc.), among which the most effective is zinc fertilizer on cherries, the most effective is copper on peach good,
