Abstract  A field experiment was carried out to investigate the effects of new foliar iron amino acids fertilizer [Fe(Ⅱ)-AA] on iron content and nutrition quality in polished rice of different varieties under split plot design . Eight varieties of high iron content rice were applied . The results demonstrated that foliar Fe(Ⅱ)-AA could promote significantly iron content in polished rice of different varieties . After Fe(Ⅱ)-AA spraying,the total average iron content in polished rice of eight varieties was3.9 9 mg.k g-1,increased significantly by 19.4 6% compared with control . The highest polished rice iron content was 4.9 7 mg.k g-1,increased significantly by34.6 2% compared with control,and observed in rice mutant Nipponbare" . In addition,foliar Fe(Ⅱ)-AA could also increase significantly protein content and essential amino acids including lysine in polished rice . The total amino acid contents were simultaneously increased . In conclusion,foliar Fe(Ⅱ)-amino acids provided an effective and economic strategy to enrich iron content and nutrition quality in rice grain .

叶面喷施氨基酸铁肥对稻米铁含量和营养品质的影响

选取8个含铁量较高的优质水稻品种,在大田条件下采用裂区设计研究叶面喷施新型氨基酸铁肥[Fe(Ⅱ)-AA]对不同品种水稻精米铁含量及其营养品质的影响。结果表明 :叶面喷施 Fe(Ⅱ)-AA对不同品种水稻精米铁含量增效显著,8个品种水稻精米总体平均铁含量达3.9 9 mg. kg-1,比对照喷清水显著提高了19.4 6% ;叶面喷施Fe(Ⅱ)-AA后,精米铁含量最高的是日本晴突变 体,达4.9 7 mg.kg-1,比对照显著提高了34.6 2% ;此外,叶面喷施Fe(Ⅱ)-AA能显著增加精米中蛋白质含量、赖氨酸等必须氨基酸含量和15种氨基酸总量。因此,叶面喷施Fe(Ⅱ)-AA可以成为生产实际 中提高稻米铁含量和营养品质的经济、有效的农艺措施之一 。
