摘　　要：通过对比不同方法、不同用量的苹果增施铁肥处理,可以看出施用铁肥处理的新梢长度、百叶鲜质量、单果质量和单位面积产量均匀提高。试验结果表明:常规施肥+硫酸亚铁0.8 kg+3 kg腐熟饼肥+0.8 kg硫酸铵混合,萌芽前作基肥穴施的处理比对照平均增产318.6 kg/0.067 hm^2,增幅10.7%;常规施肥+新梢旺长期叶面喷施0.3%柠檬酸铁3次的处理比对照平均增产261.4 kg/0.067 hm^2,增幅8.8%。By comparing the treatments with different methods and different amounts of iron fertilizer, we can see that the length of new shoots, the fresh weight of louvers, the weight of single fruit and the yield of apples treated with iron fertilizer increased evenly. The results showed that the average yield increased by 318.6 kg/0.067 hm^2(10.7%) in the treatment of conventional fertilization + ferrous sulfate 0.8 kg + 3 kg decomposed cake fertilizer + 0.8 kg ammonium sulfate before germination, and 261.4 kg/0.067 hm^2(8.8%) in the treatment of conventional fertilization + long-term foliar spraying of 0.3% ferric citrate 3 times in vigorous shoots.
