摘　　要：以鄄城县为试验地点,考察了不同氮肥水平条件下小麦的生长发育状况、产量及品质情况。结果显示:N_(3)(氮肥施用量70 kg/hm^(2))条件下,小麦株高较最高(9.35 cm),有效穗数最高(657.19×10^(4)穗/hm^(2)),穗位数最高(42.25粒),小麦产量较高(13008.50 kg/hm^(2));N_(4)(氮肥施用量80 kg/hm^(2))条件下小麦千粒质量最高(47.24 g),湿面筋质量分数最高(41.53%);N_(5)(氮肥施用量90 kg/hm^(2))条件下小麦单株分蘖数较高(6.55个),蛋白质质量分数(12.58%),显著低于其他施氮水平;不同氮肥水平下,N_(2)(氮肥施用量60 kg/hm^(2))与N_(3)(氮肥施用量70 kg/hm^(2))条件下的蛋白质质量分数分别为14.21%和14.36%,N_(4)与N_(5)条件下沉淀值显著高于其他处理,二者之间无显著差异。Shandong Juancheng County was selected as the test site to investigate the growth and development status,yield and quality of wheat under different nitrogen fertilizer levels.Under the condition of N_(3),the highest wheat plant height was 19.35 cm,the highest effective spike number was 657.19×10^(4) spikes/hm^(2),the highest spike number was 42.25 grains,and the highest wheat yield was 13008.50 kg/hm^(2).Under the condition of N_(4),the 1000-grain weight of wheat was the highest(47.24 g),and the mass fraction of wet gluten was the highest(41.53%).Under the condition of N_(5),the number of tillers per plant was 6.55,and the protein mass fraction was 12.58%,which was significantly lower than other nitrogen application levels.Under different nitrogen fertilizer levels,the protein mass fraction of wheat under N_(2)(nitrogen fertilizer application rate of 60 kg/hm^(2))and N_(3) was 14.21%and 14.36%,respectively,and the precipitation value under N_(4) and N_(5) conditions was significantly higher than that under other treatments,with no significant difference between them.
