摘要:

【目的】针对黑龙江稻区干湿交替灌溉适宜控水阈值不明确的问题,探寻实现该地区水稻高产与优质协同的灌溉模式,为该地区水稻可持续生产提供理论依据。【方法】以常规粳稻龙粳31为材料,在黑龙江省建三江七星农场田间栽培条件下,研究了轻度(MID)、中度(MOD)和重度(SED)干湿交替灌溉对水稻产量和稻米品质的影响。【结果】1) 产量和灌溉水利用效率:与当地常规灌溉(CF)相比,MID处理显著增产6.90%~11.89%,MOD对产量无显著影响,而SED则导致产量显著下降6.30%~6.70%。MID较CF降低灌溉用水量12.21%~16.23%,灌溉水利用效率提高22.42%~35.46%,节水效果显著。2) 稻米品质:MID处理降低了垩白粒率,显著改善了稻米的外观品质,而加工品质、蒸煮食味品质与CF均无显著差异。MOD处理下品质有变劣的趋势。SED处理则显著降低了稻米的精米率和整精米率及直链淀粉含量,导致稻米加工品质和食味品质变劣。【结论】MID有利于水稻高产优质协同,是适合黑龙江稻区的高产高效优质节水灌溉模式。

Abstract:

【Objective】To address the ambiguity regarding optimal water control thresholds for alternate wetting and drying (AWD) irrigation in the rice-growing regions of Heilongjiang Province, this study aimed to identify an irrigation regime that synergizes high grain yield with superior quality, thereby providing a theoretical framework for sustainable rice production in the region.【Method】Utilizing the conventional japonica rice cultivar ‘Longjing 31’ as experimental material, field trials were conducted at Qixing Farm, Jiansanjiang Branch of Beidahuang Group, Jiamusi City, Heilongjiang Province. The effects of mild (MID), moderate (MOD), and severe (SED) AWD irrigation on rice yield and grain quality were systematically evaluated.【Results】1) Regarding yield and irrigation efficiency, the MID treatment significantly enhanced grain yield by 6.90%-11.89% compared to the local conventional flooding (CF) practice. The MOD treatment exhibited no significant impact on yield, whereas the SED treatment resulted in a significant yield reduction of 6.30%-6.70%. Over the two-year period, the MID treatment significantly improved irrigation water use efficiency by 22.42%-35.46% and reduced irrigation water consumption by 12.21%-16.23%, demonstrating substantial water-saving and efficiency-enhancing effects. 2) In terms of grain quality, the MID treatment reduced the chalky grain rate and markedly improved the appearance quality of rice, while maintaining milling and cooking/eating qualities comparable to those of the CF treatment. The MOD treatment exhibited a tendency toward quality deterioration. Conversely, the SED treatment significantly reduced the milled rice rate, head rice rate, and amylose content, leading to deterioration in milling quality and eating quality.【Conclusion】The MID treatment facilitates the synergy between high yield and superior quality, representing an optimal high-yielding, high-efficiency, and water-saving irrigation method for the rice-growing regions of Heilongjiang Province.
