摘　　要：以强筋小麦临优145为研究对象,分析氮、磷、钾肥配施对其产量与品质的影响。结果表明,增施氮、磷、钾肥,都可提高产量,其影响大小为:氮肥>磷肥>钾肥,增产的主因是:穗粒数明显增加。以氮肥210kg/hm2,磷肥135kg/hm2,钾肥165kg/hm2的处理的产量最高,蛋白质含量、沉降值等品质指标最好,达到了产量与品质的最佳结合。因此,在保证氮素供应的基础上,合理配施磷钾肥,达到平衡施肥,可提高强筋小麦产量,改善小麦品质,有利于强筋小麦的高产、优质。Taking the high gluten wheat Linyou 145 as example the effect of the nitrogen, phosphorus, potassium fertilizer application on the yield and quality has been studied. The results show,increasing of the nitrogen ,the phosphorus, the potassium fertilizer could improve the yield, and its influence is： the nitrogen 〉 the phosphorus〉 the potassium. The main reason to improve yield is grain number obviously increases. Among other treatments, the yield of A1 is the best treatment, that is,applied the nitrogen fertilizer 210kg/hm^2, the phosphorus fertilizer 135kg/hm^2, the potassium fertilizer 165kg/hm^2, and its grain protein content, sedimentation value etc. are all best. It achieves the yield and quality best union. Therefore, on the basis of guaranteed nitrogen fertilizer supply, reasonably matches phosphorus fertilizer and potassium fertilizer in order to balance applied fertilizers, and improves yield and quality. It is beneficial to the high yield and quality of high gluten wheat.
