[Method] Orthogonal test was conducted to analyze oat cultivation technology in Tibet. [Result] Qingyin No.2 and Baiyan No. 8 were proved the optimal species to be grown in Lhasa with optimal sowing quantity at 150-180 kg/hm2. Sowing term is an extremely significant factor affecting growing season, and species and N fertilizer are significant factors. Al factors have none significant effects on hay yield. [Conclusion] The research provides theoretical refer-ences and technological supports for large-scale planting.展开更多
