摘　　要：以绥粳4号为材料,研究不同施氮处理对水稻产量和品质的影响。结果表明,增施氮肥可提高绥粳4号的产量,以施氮量162 kg/hm2、基蘖肥和穗粒肥比例为8∶2时产量最高;增施氮肥可提高绥粳4号的加工品质,但食味品质降低;基蘖肥与穗粒肥比例为7∶3时绥粳4号的加工品质最好,比例为10∶0时食味评分最高。The effects of different nitrogen fertilizer treatments on yield and quality of Suijing 4 were analyzed. The results showed that increasing nitrogen application amount would increase the yield of Suijing 4. The highest yield is under the condition of nitrogen fertilizer 162 kg/hm2,base tiller fertilizer and panicle fertilizer ratio is 8：2. Increasing nitrogen application amount would improve the processing quality, but reduce the eating quality. The processing quality is the best, when the rate of base tiller fertilizer and panicle fertilizer is 7：3. Taste score is the highest, when the rate of base tiller fertilizer and panicle fertilizer is 10：0.
