摘要:
【目的】 “中稻+再生稻”组合是豫南稻区新的水稻种植模式,但是头季与再生季水稻产量和稻米品质变化尚不清楚。明确其产量和米质变化规律可为豫南地区高产优质再生稻品种选择提供理论与实践依据。【方法】以两优6326等12个适于单季种植的杂交籼稻为材料,在当地高产栽培条件下,依据头季和再生季两季产量将其划分为两季产量均高(双高)、头季稻产量高再生季产量低(头高再低)、头季稻产量低再生季产量高(头低再高)和两季产量均低(双低)等四种类型,并分析了米质的差异。【结果】 1)与头季稻相比,12个组合的再生季稻米加工品质和外观品质显著改善,蛋白质含量降低,稻米食味品质不同程度变优。2)两季不同产量类型之间比较,除双低类型(仅深两优11号一个品种)外,双高类型和头高再低类型加工品质较优,而头高再低类型的外观品质和蒸煮食味品质较优。蛋白质含量在各产量类型头季稻之间无显著差异,而再生季双高类型较头高再低类型高10.7 %,比头低再高类型低1.75 %。3)齐穗后日平均温度对稻米品质的影响远大于日照时数,再生季齐穗后日平均温度较低是其稻米品质优于头季稻的重要原因。【结论】综合产量及品质,两优6326、天两优616、广两优476和丰两优香1号是适于豫南地区的高产优质再生水稻品种。
