【目的]为明确浙北稻区直播单晚水稻的适宜播期和播量提供理论参考。【方法】以常规中熟晚粳秀水09为试材，在桐乡市龙翔街道和乌镇针对不同播期和播量开展研究，分析播期和播量对生育特性、穗粒结构和产量的影响。[结果]不同播期和播量对苗峰出现期、齐穗期、成熟期以及株高、总叶龄均有明显影响。随着播期的推迟和播量的增加，有效穗数增加，每穗总粒数和实粒数显著减少，千粒重也略有降低，产量下降明显。[结论】秀水09作当地直播单晚栽培的最佳播期为5月底至6月初，最佳播量为30．0～37．5kg／hm^2。

[Objective] The research aimed to provide references for selecting suitable sowing date sowing rate for the direct seeding single cropping late rice in the north of Zhejiang province. [Method] The conventional medium maturing late japonica variety Xiushui 09 were planted in Longxiang street and Wuzhen town of Tongxiang city respectively. The effects of different sowing dates and sowing rates on growth characteristics, panicle-spikelet structure and yield were studied. [Result] Different sowing dates and sowing rates had significant influence on tillering stage, full heading time, maturity, plant height and total number of leaves. With sowing date delaying and sowing rate increasing, the effective panicle number increased, grain and filled grain number per panicle decreased, 1 000-grain weight reduced and yield decreased obviously. [Conclusion] The best sowing date was from the end of May to the beginning of June and the optimum sowing rate was 30.0-37.5 kg/hm^2.
