摘要
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3.99 mg·kg-1,比对照喷清水显著提高了19.46%;叶面喷施Fe(Ⅱ)-AA后,精米铁含量最高的是日本晴突变体,达4.97 mg·kg-1,比对照显著提高了34.62%;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.
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 was 3.99 mg·kg-1,increased significantly by 19.46% compared with control.The highest polished rice iron content was 4.97 mg·kg-1,increased significantly by 34.62% 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.
