摘　　要：通过田间试验的方法,研究了3种不同铁源的复合铁肥对花生生长效应的影响。结果表明,施用含EDDHA-Fe和柠檬酸铁的复合铁肥均能显著降低花生黄化率,有效地提高花生叶片活性铁含量以及叶片和果仁的全铁含量,从而有效地提高花生产量。综合考虑成本因素,复合肥中添加柠檬酸铁是改善石灰性土壤花生缺铁黄化的有效途径之一。Based on the field experiment, the effects of three kinds of different compound iron fertilizers on the growth of peanut are studied. The results show that, applying compound iron fertilizers containing EDDHA-Fe and citric acid iron can decrease the chlorosis rate significantly, increase the active iron content in leaves and the total iron content in leaves and kernals, so as to improve the yield of peanut effectively. Considering the cost of processing, the compound fertilizer added citric acid iron is an effective way to improve peanut chlorosis in calcareous soil.
