为研究甘肃中部干旱半干旱地区小黑麦的饲用价值，筛选最适种植品种，对从中国农业科学院作物科学研究所引进的11个小黑麦新品系进行了连续2 a的品比试验，鉴定其田间农艺性状、鲜草产量、干草产量、茎叶比等差异。结果表明，3297、 5全50鲜草产量分别为68.25、67.05 t/hm2，较对照品种中饲3241分别增产7.70%、4.81%；干草产量分别为23.55、22.80 t/hm2，较对照品种中饲3241分别增产5.64%、2.25%；茎叶比分别为1.78、1.87，饲草可利用价值高。综合评价认为，3297、5全50以开花盛期获取鲜干草为佳。
In order to study the feeding values of triticale in arid and semi-arid areas of central Gansu, 11 new triticale lines introduced from the Institute of Crop Sciences, Chinese Academy of Agricultural Sciences were studied for 2 consecutive years to investigate the differences in field agronomic traits, fresh forage yield, hay yield and stem-leaf ratio so as to select the optimum variety for the local area. The results showed that the fresh forage yield of the top two lines were 3297 and 5Quan50, i.e., 68.25 and 67.05 t/ha, respectively, which were 7.70% and 4.81% higher than that of the control variety Zhongsi 3241, respectively, the hay yields were 23.55 t/ha and 22.80 t/ha, respectively, which were 5.64 % and 2.25 % higher than that of the control variety Zhongsi 3241, respectively. The stem-leaf ratio of the top two were 1.78 and 1.87, respectively, which were considered as lines with high feeding value potentials. Comprehensive evaluation showed that triticale line 3297 and 5Quan50 would be ideal for obtaining fresh forage or hay at the bloomin stage.
