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。

摘  要：
A chlorosis apple orchard located in 13 thregiment in Alar was investigated in this study. The indices(including iron,manganese,magnesium,zinc,nitrogen,phosphorus,potassium,p H 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 p H soil. The results showed that this orchard was diagnosed with iron deficiency due to high p H value of its soil. Then the orchard was thoroughly dripped with mixed solution,which was made according to the formula,citric acid 1 kg,humic acid2 kg,fulvic acid 2 kg,iron sulfate 1 kg per 667 m2. After dripping,the p H 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.
