摘要: 为了明确有机活性氮素肥料(简称OAN)对水稻植株生长和产量、品质的影响,提出其生产应用配套技术。以‘嘉引2 号’为供试水稻品种,设置不施任何肥料的空白对照和4 种不同施肥处理,开展了田间小区对比试验。T2 处理(OAN配合磷钾肥施用)与对照及其他施肥处理相比,水稻单株有效穗数增多,成熟期植株干物质积累量增加;产量比T1 处理(尿素配合磷钾肥施用)增产0.95%,比T3 处理(单施OAN)增产12.94%,比T4 处理(单施尿素)增产9.45%;稻米粒长和胶稠度增加,垩白米率降低,蛋白质和直链淀粉的含量提高,外观品质、蒸煮食味与营养品质有所改善。OAN与磷钾肥配合施用,具有促进水稻植株生长、增加籽粒产量和改善稻米品质的应用效果。
