摘要/Abstract

摘要：

小麦开花后叶面喷施氮肥能延缓衰老、提高产量, 但其对小麦氮素利用效率的影响鲜见报道。本研究以强筋冬小麦品种济麦229为试验材料, 采用两因素随机区组设计, 设置2个叶面喷施尿素的时期, 分别为开花后7 d (S)和21 d (T), 设置4个尿素溶液浓度(0、2%、6%和10%), 探索开花后叶面喷施尿素对冬小麦氮素吸收积累及籽粒产量和氮素利用效率的影响。结果表明, 小麦籽粒产量随喷施尿素溶液浓度的提高呈先增加后降低的趋势, 并在2%浓度水平下达到最高(比对照增产5.1%), 这主要得益于千粒重的增加(比对照提高3.3%)。开花后不同时间喷施2%浓度尿素溶液均促进了开花前营养器官贮藏氮素向籽粒中的再分配, 亦增加了开花后同化氮素输入籽粒量, 平均增幅分别为8.8%和21.1%; 单位面积籽粒氮积累量及氮素收获指数的增幅分别为10.9%和7.9%, 进而显著提高了籽粒含氮量、蛋白质含量及氮素利用效率。采用2%的尿素溶液叶面喷施, 将喷施时间由开花后7 d推迟至开花后21 d, 籽粒氮素积累量、籽粒产量和氮素利用效率的增幅更大。综上所述, 开花后叶面喷施2%的尿素溶液可促进强筋冬小麦花后氮素的吸收及营养器官临时贮存氮素向籽粒的再分配, 从而显著提高籽粒蛋白质含量和产量、增加籽粒产量、提高氮素利用效率。灌浆中后期喷施比灌浆前期喷施对籽粒蛋白质含量和产量、籽粒产量和氮素利用效率提高的幅度更大。

Abstract:

Foliar spraying of nitrogen fertilizer can delay senescence and increase yield of wheat post anthesis, but few studies of its effect on nitrogen use efficiency of wheat is known. In this study, Jimai 229, a strong gluten winter wheat variety, was used as experimental material, and a two-factor random block design was used to set two periods of urea spraying on leaves, namely 7 d (S) and 21 d (T) post anthesis. Setting 4 urea solution concentrations (0, 2%, 6%, and 10%) was to explore the effects of foliar urea spraying post anthesis on nitrogen absorption and accumulation, grain yield, and nitrogen use efficiency in winter wheat. The results showed that grain yield of wheat increased first and then decreased with the increase of spraying urea solution concentration, and reached the highest at 2% concentration (5.1% higher than the control), mainly due to the increase of 1000-grain weight (3.3% higher than the control). Spraying 2% urea solution at different times post anthesis promoted the redistribution of pre-flowering storage nitrogen to grains, and increased the amount of post-flowering assimilation nitrogen to grains by 8.8% and 21.1%, respectively. Grain nitrogen accumulation per unit area and nitrogen harvest index increased by 10.9% and 7.9%, respectively, resulting in significantly increasing the grain nitrogen content, protein content, and nitrogen use efficiency. When 2% urea solution was applied foliar spraying, and the spraying time was delayed from 7 days post anthesis to 21 days post anthesis, the increase of grain nitrogen accumulation, grain yield and nitrogen use efficiency was greater. In conclusion, spraying 2% urea solution on leaves post anthesis can promote the absorption of nitrogen and the redistribution of temporary storage nitrogen in vegetative organs to grains post anthesis, thus significantly improving grain protein content and yield, grain yield, and nitrogen use efficiency. Grain protein content and yield, grain yield and nitrogen use efficiency were increased more by spraying at the middle and late filling stages than at the early filling stage.
