硬粒小麦4286和普通小麦小堰6号和小偃107籽粒蛋白质含量随施氮量的增加呈递增趋势,但增幅不同;蛋白质产量呈常态变化;单粒蛋白质含量及其变化与籽粒蛋白质含量变化相似。施氮量以157.5kg/hm~2时籽粒蛋白质产量较高。
Triticum durum 4286, Triticum aestivum xiaoyan 6 and Xiaoyan 107 showed an increasing trend with the increase of nitrogen application rate, but with different amplifications; the yield of protein showed normal variation; the content of single grain protein and its variation and the change of grain protein content similar. When the nitrogen application rate was 157.5kg / hm ~ 2, the grain protein yield was higher.
