采用盆栽试验方法研究了氮肥运筹对强筋小麦产量和品质的影响,试验结果表明:合理运筹氮肥能够显著提高强筋小麦籽粒产量。拔节期叶面喷施氮肥显著提高了强筋小麦的株高、穗长、穗数、穗粒数和千粒重,从而促进小麦获得了最高产量;适当增加中、后期氮肥施用比例有利于改善强筋小麦品质,以拔节期和抽穗期分两次追施氮肥效果最佳。综合产量和品质效应,以拔节期喷施氮肥为最佳氮肥运筹方法。
The pot experiment was conducted to study the effects of nitrogen fertilizer on the yield and quality of strong gluten wheat. The results showed that applying nitrogen fertilizer rationally could significantly increase grain yield of strong gluten wheat. Spraying nitrogen fertilizer at jointing stage significantly increased the plant height, spike length, spike number, spike grain number and 1000-grain weight of strong gluten wheat, thus promoting the highest yield of wheat. Appropriately increasing the proportion of nitrogen fertilizer application in middle and late stage was helpful to improve the strong gluten Wheat quality, with jointing and heading two topdressing nitrogen best. Integrated yield and quality effects, nitrogen application at the jointing stage was the best nitrogen fertilizer management method.
