摘要：

为探讨华浙优261在浙江台州作连晚栽培的特征特性和高产栽培技术，设计3种不同密度和3个不同氮肥用量，按单裂区试验处理排列，研究不同氮肥用量和移栽密度对其产量及有关性状的影响。结果表明，华浙优261在椒江区作连晚栽培时，移栽密度1.2万/667 m2、纯氮用量14 kg/667 m2时能获得最高产量559.58 kg/667 m2，显著高于其他处理，其穗粒结构为有效穗数19.01万/667 m2、每穗实粒139.05粒、结实率81.49%、千粒重22.03 g。

Abstract:

An experiment was designed to study the effects of different planting densities and different nitrogen application rates on the yield of Huazheyou 261 in late season in Jiaojiang District; The results showed that Huazheyou 261 could achieve the highest yields of 559.58 kg/667 m2 and ideal panicle grain structure when the transplanting density was 12 000/667 m2 and the pure nitrogen application rate was 14 kg/667 m2. The panicle grain structure was 190 100/667 m2 of effective panicle, 81.49% of seed setting rate, 139.05 grains per panicle, and 22.03 g of 1 000-grain weight under this treatment.

Key words: indica hybrid rice, Huazheyou 261, nitrogen application rate, transplant density, yield
