摘要:
以泰兴香荷芋为材料，于10叶期叶面分别喷施0.25 mol/L(T1)、0.5 mol/L(T2)、0.75 mol/L(T3)和0 mol/L(对照T4)的FeSO4，研究FeSO4处理前后芋头株高、叶面积指数、产量等性状及不同器官矿质元素对铁肥的响应。结果表明，叶面喷施铁肥对株高的影响达到显著水平，对叶面积指数的影响未达显著水平；施铁肥后12叶期叶片和叶柄铁含量明显增加。其中，T1~T3各处理叶片含铁量分别为483.57、1 340.90、1 402.38 mg/kg，T2、T3处理显著高于对照处理；各处理理论母芋、子孙芋产量变幅分别为4 455.45 kg/hm2(T2)~5 218.50 kg/hm2(T4)、10 517.55 kg/hm2(T2)~11 966.55 kg/hm2(T3)，差异均未达显著水平；在 T3处理下，子芋铁、钙、钾、镁含量均显著高于T4处理；在T1、T2处理下，子芋的铁、钙、钾、镁含量对叶面铁肥的反应因元素种类和铁肥浓度而异。相关分析表明，子芋Fe含量与Ca、Mg含量呈极显著正相关，相关系数分别为0.98、0.85。
