试验结果表明，在宁夏引黄灌区灌淤土上增施基肥可增产１５．２％，并显著提高了小麦籽粒蛋白质含量，使蛋白质产量增加４４．８％，实现了产量和蛋白质含量同步提高，但对蛋白质品质的影响因品种而不同。不同基肥水平结合生育后期叶面喷氮，对产量影响不显著。虽可增力。蛋白质含量，却不能使蛋白质产量大幅度提高；对蛋白质品质的影响因品种关系蛋白质高低亦不同。 The results showed that the increase of basal fertilizer on irrigated silt irrigation area in Ningxia Yellow River Irrigation Area could increase the yield by 15.2%, increase the protein content of wheat significantly, increase the protein yield by 44.8% and achieve the simultaneous increase of yield and protein content, But the impact on protein quality varies by breed. Different basal levels combined with foliar spray nitrogen during late growth had no significant effect on the yield. Although power can be increased. Protein content, but can not make a substantial increase in protein yield; the impact of protein quality due to the relationship between the different varieties of proteins are also different.
