摘　　要：试验研究氮肥施用量对优质水稻品种津川1号产量及商品品质的影响。结果表明,在纯氮施用量0-300kg/hm^2内,津川1号产量及产量因子有效分蘖、每穗粒数、千粒重与纯氮施用量相关系数分别为0.908^＊＊、0.878＊＊、-0.646^＊＊、-0.895^＊＊;津川1号出糙率、出精率、整精米率与纯氮施用量相关系数分别为0.777^＊＊、0.645^＊＊、0.640^＊;垩白粒率、垩白大小、垩百度与纯氮施用量相关系数分别为-0.932^＊＊、-0.534^＊、-0.952^＊＊。因此,在试验范围内增施氮肥施用量可以提高津川1号的产量及商品品质。This is a research on different nitrogen levels on grain yields and commercial quality of Jinchuan 1.The results showed that in the range of N 0-300 kg/hm^2,the correlation coefficients between the pure nitrogen employment grain yield and panicles and grains per panicles and 1000-grain weight respectively is 0.908^ ＊＊,0.878^ ＊＊,-0.646 ^＊＊,-0.895 ^＊＊;between the rate of husked rise,essence rate,entire polished rice rate respectively is 0.777^＊＊、0.645^＊＊、0.640^＊;beitween chalky rice rate,chalkiness,chalky area respectively is-0.932^＊＊、-0.534^＊、-0.952^＊＊.So,Increases nitrogen fertilizer employment in this range can enhances the grain yield and commercial quality of Jinchuan 1.
