摘要
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)。
By increasing the application of chemical fertilizers, seed production and protein contents of wheat grains as well as protein production per unit area determined by the product of the above two were drastically increased.The action of different varieties ranked the second. With the same amount of fertilizers applied, among the different wheat cultivars, the Bumper Harvest No:3 has the highest protein contents,while Jingnong 79-13 and 806173 have the higher grain and protein production. There is no significant difference between these wheat cultivars. Leaf surface application of chemical fertilizers after heading can increase seed and protein production. Sowing time however, has no apparent effect on seed production, protein contents and yield. From the point of view of high production and good quality, the best completion of cultural methods was the treatment 9 i. e.A_3B_3C_2D_1.
