摘要
不同叶龄期施氮对中筋小麦品种扬麦10号籽粒产量和品质性状影响的研究结果表明:籽粒产量、蛋白质含量及其产量、容重、出粉率、千粒重、面筋含量、面团吸水率、面团形成时间、断裂时间、弱化度等以基追比为5∶5的处理优于基肥一次性施用的处理;籽粒蛋白质含量和产量均表现为基肥加后期追肥处理最高,其次是基肥加前期追肥处理;容重、面团稳定时间、断裂时间、公差指数以3/0叶期追肥效果最优,千粒重、面团吸水率和面团形成时间则随施氮时期推迟而呈上升趋势。
The effect of N applying leaf ages on grain yield and quality of mediumgluten wheat (Triticum aestivum L., cv Yangmai 10) were studied in 1998~2000. The ratio of basal: top dressing with 180 kg(N)·hm-2 significantly affected grain yield, protein content and protein yield. The grain yield and quality in the treatments of applying N during late stages were superior to those during early stages. Supplying N at 3/0 leaf age got the highest test weight, dough stability time, breakdown time and mixing tolerance index. The later the N applied, the greater the 1000grain weight, flour absorption and dough development time were.
