摘要：

为探讨不同密度、施氮量及其互作对青稞品质的影响，以全国冬青稞高产纪录新品种‘云大麦12号’为材料，采用裂区试验，对密度、施氮量及其互作对‘云大麦12号’的蛋白质、γ-氨基丁酸、β-葡聚糖、总淀粉、直链淀粉、总黄酮、生物碱和脂酸等营养和功能成分品质的影响进行研究。结果表明，‘云大麦12号’的γ-氨基丁酸、β-葡聚糖和脂酸受密度和施氮量影响小，蛋白质和直链淀粉含量主要受施氮量的影响，总淀粉、总黄酮和生物碱受施氮量和密度的影响均较大。‘云大麦12号’作为食品特别是功能食品时最佳密氮组合为D1N3。

Abstract:

In order to explore the effects of different planting densities, nitrogen application rates and their interactions on the quality of highland barley, ‘Yundamai 12’, a new high-yield record variety of winter highland barley in China, was used as the material to study the effects of planting density, nitrogen application rate and their interaction on the quality of nutritional and functional components, such as protein, γ-aminobutyric acid, β-glucan, total starch, amylose, total flavonoids, alkaloids and fatty acids by split plot experiment. The results showed that the content of γ-aminobutyric acids, β-glucan and fatty acids of ‘Yundamai 12’ were less affected by planting density and nitrogen application rate. Protein and amylose contents were mainly affected by nitrogen application rate. The content of total starch, total flavonoids and alkaloids were greatly affected by nitrogen application rate and planting density. In summary, the best combination of planting density and nitrogen application rate for ‘Yundamai 12’ as food, especially functional food, is D1N3.
