Abstract:

采用盆栽试验,探索了叶面喷施硫酸亚铁、氨基酸和尿素籼稻(OryzasativaL.)“浙农952”糙米中铁积累的效应,及混配喷施铁肥对糙米中锌、钙、镁含量和蛋白质含量的影响。结果表明,喷施不同配比的铁氮混配肥料对糙米中铁、锌、钙、镁和蛋白质的含量有明显不同的影响。喷施0.1%FeSO·47H2O+0.4%氨基酸+0.2%尿素混配肥(处理8)后“,浙农952”糙米中的铁含量最高,为10.28mg·kg-1,与对照相比提高了57.67%,达到差异显著水平,同时糙米的锌、钙、镁及蛋白质的含量也分别提高了12.45%、12.77%、5.82%和11.98%,明显改善了稻米的营养品质。
