摘　　要：以新疆阿拉尔13团黄化苹果园为研究对象,对果园土壤、叶片、灌溉水的矿物元素(铁、锰、镁、锌、氮、磷和钾)、p H、叶绿素等相关指标分析,以期为因高p H的碱性土壤导致苹果及其它果树缺铁的防治提供参考。结果表明:该果园被诊断为高p H导致缺铁失绿,按667 m2施用柠檬酸1 kg、腐殖酸2 kg、黄腐酸2 kg、硫酸亚铁2 kg的量,配制成混合液全园滴灌。经矫治处理后,果园土壤p H降至8.10左右,黄化叶片1周后开始返绿,半个月后黄化症状明显减轻,一个半月后黄化症状完全消除。A chlorosis apple orchard located in 13th regiment in Alar was investigated in this study. The indices （including iron, manganese, magnesium, zinc, nitrogen, phosphorus, potassium, pH and chlorophyll） of orchard soil, leaves, irrigation water were analyzed in order to provide references for the treatment and prevention of iron deficiency because of high pH soil. The results showed that this orchard was diagnosed with iron deficiency due to high pH value of its soil. Then the orchard wasthoroughly dripped with mixed solution, which was made according to the formula, citric acid 1 kg, humic acid 2 kg,fulvic acid 2 kg, iron sulfate 1 kg per 667 m2. After dripping, the pH was low down near 8. 10,and chlorosis leaves returned to the green in one week, and the chlorosis symptom of the orchard was obviously alleviated in half a month, and the chlorosis symptom was thoroughly disappeared in one and a half month.
