A two-factor split-plot design was used. The main plot was the amount of nitrogen fertilizer added， and the sub-plot was the sowing rate. The amount of nitrogen fertilizer added was N₁ 0 kg·hm^-2， N₂ 60 kg·hm^-2， N₃ 120 kg·hm^-2， N₄ 180 kg·hm^-2， N₅ 240 kg·hm^-2 and N₆ 300 kg·hm^-2. The sowing rate was D₁ 15.0 kg·hm^-2， D₂ 22.5 kg·hm^-2 and D₃ 45 kg·hm^-2， so as to screen out the optimal planting configuration combination of ‘Baqing’ forage production. The results showed that under the same sowing rate， with the increase of nitrogen application rate， the production performance and nutritional quality of ‘Baqing’ were increased to varying degrees. Under the same nitrogen application rate， with the increase of sowing rate， the production performance and nutritional quality of ‘Baqing’ showed a trend of increasing first and then decreasing. Principal component analysis showed that 240 kg·hm^-2 nitrogen application rate and 22.5 kg·hm^-2 sowing rate were the optimal planting configuration for the production of ‘Baqing’. The above optimal planting configuration has certain theoretical reference value and production guiding significance for the promotion and utilization of ‘Baqing’ in the alpine region of Lhasa，

nutans ‘Baqing’）为研究对象，采用双因素裂区设计，主区为氮肥添加量，副区为播种量，氮肥添加量为N₁ 0 kg·hm^-2，N₂ 60 kg·hm^-2，N₃ 120 kg·hm^-2，N₄ 180 kg·hm^-2，N₅ 240 kg·hm^-2和N₆ 300 kg·hm^-2，播种量为D₁ 15.0 kg·hm^-2，D₂ 22.5 kg·hm^-2和D₃ 45 kg·hm^-2，从而筛选出‘巴青’垂穗披碱草饲草生产最优种植配置组合。结果表明，在相同播种量条件下，随着施氮量的增加，‘巴青’垂穗披碱草饲草生产性能及营养品质均有不同程度的提高。在相同施氮量条件下，随着播种量的增加，‘巴青’垂穗披碱草饲草生产性能及营养品质大致呈现先升后降的趋势。经主成分分析得出，240 kg·hm^-2的施氮量与22.5 kg·hm^-2的播种量是‘巴青’垂穗披碱草饲草生产最优种植配置，上述最优种植配置对‘巴青’垂穗披碱草在西藏拉萨高寒地区的推广利用具有一定理论参考价值和生产指导意义。, authors=苏志刚¹, 韩有健¹, 张建杭¹, 陈盈熹¹, 杜金龙¹, 顾涛¹, 郝小玉¹, 苗彦军¹, authorsList=苏志刚, 韩有健, 张建杭, 陈盈熹, 杜金龙, 顾涛, 郝小玉, 苗彦军,
