摘要: 本文采用裂区设计,研究了不同氮肥施用量和不同施用比例(基蘖肥与穗粒肥比例)对穗重型品种绥粳4号和穗数型品种垦鉴稻6号产量和稻米品质的影响。试验结果表明,穗重型品种在纯氮用量为150 kg/hm2、基蘖肥与穗粒肥比例为7∶3时产量最高,达8 750.2 kg/hm2;穗数型品种在纯氮用量为128 kg/hm2、基蘖肥与穗粒肥比例为7∶3时产量最高,达9 083.3 kg/hm2;合理施用氮肥可以改善稻米品质,特别是蒸煮食味品质,本试验条件下纯氮用量为128 kg/hm2时大米的品质最佳。

Abstract: This paper studied the effects of different nitrogen rates and nitrogen ratios on yield and grain quality of Suijing 4 (panicle weight type cultivar) and Kenjiandao 6 (panicle quantity type cultivar) by using split plot design. The results showed that the highest yield of panicle weight type cultivar is at nitrogen rate 150 kg/hm2 and nitrogen ratio 7∶3, the highest yield of panicle quantity type cultivar is at nitrogen rate 120 kg/hm2 and nitrogen ratio 7∶3. Reasonable application of nitrogen fertilizer could improve grain quality, especially cooking and eating quality.  Under this experiment condition, the nitrogen application of 128 kg/hm2 would gain the best grain quality.

Key words: rice, nitrogen, yield, grain quality
