| 中文摘要: |
| 为了研究施肥和播期对西藏青稞VE含量的影响，采用三因素五水平二次旋转回归组合设计方法，选择4个西藏春青稞品种，以播期、底肥施用量、追穗肥时期作为生产上的决策变量，以青稞VE含量为目标函数，研究了不同农艺措施对西藏青稞VE含量的影响。结果表明，对西藏青稞VE含量影响的大小依次为底肥施用量>追穗肥时期>播期；底肥施用量和追穗肥时期是影响西藏青稞VE含量的关键措施因子。并根据试验结果筛选出最佳农艺措施方案。 |
| 英文摘要: |
| The influence of different agronomic measures on vitamin E content of Tibetan spring naked barley was studied by experiment of 4 varieties. Seeding time, basal fertilizer quantity and dressing spike fertilization time were independent variables, vitamin E content of Tibetan spring naked barley was dependent variable. The result showed that the rank of effects on vitamin E content of Tibetan spring naked barley were as basal fertilizer quantity > pursuing spike fertilization time > seeding time, so the basal fertilizer quantity and dressing spike fertilization time are the main controlling factors. The best cultivation scheme could be chosen according to experimental result. |
