增施化肥能显著提高小麦籽粒、蛋白质含量及其二者乘积所决定的单位面积籽粒蛋白质产量。品种作用次之。同等施肥量,以丰产3号组合的蛋白质含量最高,而京农79—13与806173籽粒和蛋白质产量较高,而且两者无显著差别。抽穗后叶面喷肥能增加籽粒及蛋白质产量。播期对籽粒以及蛋白质含量、产量均无明显影响。从高产、优质衡量,本试验最佳配套组合是处理9(A_3B_3C_2D_1)。 The application of chemical fertilizers can significantly increase the grain protein content per unit area and grain protein yield per unit area of ​​wheat. Second, the role of species. The same amount of fertilizer to the combination of high yield of the highest protein content, and Jingong 79-13 and 806173 higher grain and protein yield, but no significant difference between the two. After heading, foliar spray can increase grain and protein yield. Sowing date had no significant effect on grain and protein content and yield. From high yield, high quality measurement, the best combination of this experiment is to deal with 9 (A_3B_3C_2D_1).
