| 摘 要： | 通过对不同时期追氮小麦籽粒蛋白质积累规律的研究表明:在小麦灌浆成熟过程中,籽粒蛋白质含量的变化为开花始期较高,开花3天后下降,第7天达最低,以后又呈上升趋势;而籽粒中非蛋白N的含量始终呈下降趋势;千粒蛋白质重量的变化明显有两个迅速增长阶段;不同时期追N均可增加籽粒蛋白质含量和千粒蛋白质绝对量,但对不同品种效果有所不同。

| Abstract: | The study of accumulation laws of wheat grain protein by N application in different periods shows that the variations in grain protein content are higher in the process of the milking to maturing stages than in the initial blossoming stage, but after the third day, it begins to decrease, and in the 7th day it reaches the minimum, and after that, protein content tends to increase. The protein weight of 1000-kernal (PWTH) will have two fast raising periods. The protein content and PWTH after seed formation by N application in different stages can be raised, but its effect on different wheat cultivars is different. |
