Abstract: In this study,Secale cereale L. ‘Gannong No.2’ was used as the experimental material,and ‘Dongmu 70’ and ‘Black feeding rye’ were used as controls to evaluate the adaptability of ‘Gannong No.2’ in 2018-2019 in different regions of Qinghai Province (Haiyan,Huangzhong,Ping'an). The results showed that,from a single factor point of view,the averaged hay yield (13.04 t·hm^-2) of ‘Gannong No.2’ were significantly higher than the 2 controls at 3 experimental sites,the average content of fiber was significantly lower than the 2 controls;among 3 experimental sites,the average hay yield (12.06 t·hm^-2) of 3 rye varieties in Haiyan was significantly higher than that of Huangzhong and Ping'an. For 2 factors,the average hay yield of ‘Gannong No.2’ (14.38 t·hm^-2) in 2018 was significantly higher than other treatments when consider the interaction of varieties and years;for the interaction of experimental sites and years,average hay yield of 3 rye varieties at Haiyan in 2018 (14.47 t·hm^-2) was significantly higher than that of other treatments. In conclusion, ‘Gannong No.2’ had the highest hay yield and best nutritional quality among the 3 varieties,and is suitable to be cultivated in Haiyan,Huangzhong,and Ping'an districts of Qinghai province and other regions with similar climate.

摘要： 本试验以‘甘农2号’黑麦(Secale cereale L.)为试验材料，以‘冬牧70’和‘黑饲麦’为对照，来评价‘甘农2号’在2018-2019年在青海省不同区域(海晏县、湟中县、平安区)的适应性。结果表明：3个黑麦品种中，‘甘农2号’在3个试验点的平均干草产量(13.04 t·hm^-2)显著高于‘冬牧70’和‘黑饲麦’，平均纤维含量显著低于‘冬牧70’和‘黑饲麦’；3个试验点中，海晏点3个黑麦品种的平均干草产量(12.06 t·hm^-2)显著高于湟中和平安点；品种×年份交互作用中，2018年‘甘农2号’黑麦的平均干草产量(14.38 t·hm^-2)显著高于其他处理；试验点×年份交互作用中，2018年海晏点3个黑麦品种的平均干草产量(14.47 t·hm^-2)显著高于其他处理。综上所述，‘甘农2号’黑麦干草产量和营养品质高且较稳定，适应青海省海晏县、湟中县和平安区以及其他气候相似区种植。
