摘要： 为探索和挖掘国审稻‘盐两优2208’的栽培措施和高产潜力，本研究采用多因素随机区组试验设计，分析了不同播期、种植密度和施肥量对优质国审稻‘盐两优2208’产量及其产量性状的影响。结果表明：播期、种植密度和施肥量等因素对‘盐两优2208’的产量及其产量性状均有极显著影响；不同播期、种植密度和施肥量对产量及其相关性状的互作效应发现，产量分别在A2B2、A2C2和B2C2互作效应下达到最高，产量相关性状在互作效应影响下，在不同处理间的差异较为复杂，总体来看，千粒重、结实率和有效穗对产量潜力关联较大，在这几个相关性状值在互作效应中最高时，产量潜力往往也最高。在‘盐两优2208’高产栽培时，应适时播种，合理密植，注重灌浆期水肥管理，氮肥施用适当后移，为增加穗粒数并提高结实率，需在齐穗时增施粒肥，为实现高产奠定基础。

Abstract: To explore the cultivation measures of the national trial rice‘Yanliangyou 2208’and tap its highyield potential, this study adopted the multi-factor randomized block trial design to analyze the effects of different sowing dates, planting densities and fertilizer amounts on yield and yield characters of‘Yanliangyou 2208’. The results showed that the sowing date, planting density and fertilizer amount had extremely significant effect on the yield and yield characters of‘Yanliangyou 2208’. The yield reached the highest under the interaction effect of A2B2, A2C2 and B2C2 respectively. Under the interaction effect, the yield-related characters were more complicated in different treatments. In general, 1000-grain weight, seed setting rate and effective spike had great correlations with yield potential, and the yield potential tended to be the highest when these correlation characters were the highest among the interaction effects. In‘Yanliangyou 2208’high-yield cultivation, we should take timely sowing, reasonable planting density and focus on water and fertilizer management during grain filling stage, also, nitrogen application should be postponed appropriately. In order to increase grain number per spike and seed setting rate, spike fertilizer should be applied at the time of heading. All these measures lay a foundation for achieving high yield.
