| 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.

| Abstract: | 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 fert... |
