| 摘 要： | 采用田间小区试验方法，研究了追施氮肥对小麦烟农5158产量和品质的影响。结果表明：追施氮肥对有效穗数影响较大，基施70％＋拔节期追施30％处理产量最高；氮肥施用时期后移能显著提高小麦蛋白质、湿面筋含量和稳定时间，并且随着后期追肥比例的增加而增加；随施氮后延，氮肥对面粉白度有降低的作用，而后又有所回升。在本试验条件下，综合考虑产量、品质和白度认为，基施70％＋拔节期追施30％处理可以获得较高的产量和品质，同时保证了面粉白度。

| Abstract: | The field plot experiment was used to study the effects of topdressing nitrogen fertilizer on yield and quality of wheat variety Yannong 5158. The results showed that topdressing nitrogen fertilizer had an apparent influence on effective spike number., and the treatment of basal application of 70% nitrogen and topdressing 30% nitrogen at jointing stage had the highest yield. The grain protein and wet gluten contents and stable time could be significantly improved by delaying nitrogen application stage, and increased with the increase of topdressing nitrogen proportion. With the delay of nitrogen application stage, wheat flour whiteness declined and then raised. Comprehensively considering yield, quality and flour whiteness, the treatment of basal application of 70% nitrogen and topdressing 30% nitrogen at jointing stage had higher yield and quality and better flour whiteness. |
