摘　　要：合理的氮肥运筹方式是水稻高产栽培的重要措施。为了更好的发挥水稻新品种蜀优217在成都平原的高产潜力,研究了不同氮肥运筹方式对其产量的影响。结果表明,蜀优217在氮肥用量为10~12 kg/667 m2,且底肥∶蘖肥∶穗肥=7∶0∶3时,产量性状协调,穗大粒多,结实率高,最终获得高产。The reasonable nitrogen application method is an effective measure for high yield cultivation of rice.In order to better play the high yield potential of the new rice variety Shuyou 217 in Chengdu plain,an experiment was conducted to study the effects of nitrogen fertilizer levels and application methods on yield of Shuyou 217.The results showed that the yield is highest when the amount of Nitrogen was 10~12 kg/667 m2 and the proportion of basal fertilizer,tillering fertilizer and panicle fertilizer was 7∶0∶3.
