摘要:: 通过花生盆栽试验的方法，研究了复混肥中添加EDDHA-Fe、柠檬酸铁和硫酸亚铁后对土壤pH、铁的有效性和花生产量的影响，以及不同形态的铁在石灰性土壤中的形态转化，以期探讨不同形态的复混铁肥在石灰性土壤中的有效性。结果表明：在花生不同的生育期，添加柠檬酸铁、EDDHA-Fe和硫酸亚铁3种铁肥处理其花生根际土壤的pH较对照分别下降了0.18～0.30、0.06～0.15、0.04～0.07个单位。土壤施入柠檬酸铁和EDDHA-Fe复混铁肥后，土壤溶液有效铁浓度均显著高于添加硫酸亚铁的铁肥处理，分别提高了120.40%～167.60%和117.38%～159.38%。与硫酸亚铁复混铁肥相比，添加EDDHA-Fe和柠檬酸铁的复混肥能提高铁在有效形态中的分配，显著增加了土壤有效铁的供给，且其花生叶片中活性铁和全铁含量均显著高于硫酸亚铁复混铁肥处理，单株花生果仁质量分别是硫酸亚铁复混铁肥处理的1.37倍和1.52倍，差异显著。此外，柠檬酸铁和EDDHA-Fe复混铁肥处理花生果仁中的全铁含量也显著高于硫酸亚铁复混铁肥处理，分别提高了31.4%和54.9%。综合分析花生的生长和土壤供铁特性，建议生产实践中复混肥添加柠檬酸铁即可达到增产、提质的效果。

Abstract:: In order to evaluate the availability of EDDHA-Fe，ferric citrate and ferrous sulfate adding to the compound fertilizers，peanut pot experiment was carried to study the soil pH，iron availability and peanut yield after fertilization.The results showed that the pH of peanut rhizosphere were decreased by 0.18-0.30，0.06-0.15 and 0.04-0.07 respectively when applied compound EDDHA-Fe，ferric citrate and ferrous sulfate fertilizers.After applying of compound ferric citrate and EDDHA-Fe fertilizer，available iron concentration of the soil solution was significantly higher than compound ferrous sulfate added，where were increased by 120.40%-167.60% and 117.38%-159.38%，respectively.Compared to compound ferrous sulfate fertilizer，applying compound EDDHA-Fe and ferric citrate fertilizer could improve the concentration of available iron in the form of distribution，significantly increase the supply of soil available iron.And active iron and total iron content of peanut leaves were significantly higher than that of compound ferrous sulfate fertilizer treatment.Peanut kernels weights of per plant were 1.37 and 1.52 times of compound ferrous sulfate fertilizer treatment,and the difference was significant.In addition，total iron contents of peanut kernels were significantly higher than that of the compound ferrous sulfate fertilizer treatment，which were increased by 31.4% and 54.9%，respectively.In a word，adding ferric citrate to the compound fertilizer during the process of factory production could reach high yield，good quality of peanut in calcareous soil depending on the peanut growth and properties of iron in soil in this experiment.
