| 摘要: |
| 【目的】对黄土高原黄河灌区饲用小黑麦（Triticale wittmack）的适应性进行评价，为筛选适宜该区域种植的优质饲用小黑麦品种提供参考。【方法】2022年在山西太原市清徐县开展甘农2号、石大1号、冀饲1号、冀饲2号、冀饲3号、冀饲4号、中饲1048、中饲3297、临草2号、晋饲草1号和优能共11个饲用小黑麦的适应性研究，并利用主成分分析（PCA）对参试品种的产量、农艺性状和营养品质等指标进行综合评价。【结果】供试11个饲用小黑麦产量、农艺性状和营养品质等均存在一定差异，其中冀饲3号的株高（195.00 cm）、鲜草产量（42.47 t/hm2）、干草产量（11.37 t/hm2）、粗蛋白产量（1.19 t/hm2）、产奶净能（5.56 MJ/kg）、产奶量（1 301.48 kg/t）、相对饲喂价值（88.83%）均为最高；冀饲2号的干鲜比（0.25）最小 ；石大1号的酸性洗涤纤维（ADF）含量最低（38.19%）；晋饲草1号的中性洗涤纤维（NDF）含量最低（60.76%），而粗蛋白含量（10.74%）、总可消化养分（53.94%）和增重净能（2.34 MJ/kg）、相对牧草质量（95.42%）均为最高。主成分分析表明，综合排名前二的饲用小黑麦品种为晋饲草1号和冀饲3号。【结论】晋饲草1号和冀饲3号可作为优良饲用小黑麦品种在黄土高原黄河灌区推广种植。 |

| Abstract: |
| 【Objective】The aim of this study was to evaluate the adaptability of forage triticale（Triticosecale wittmack）in the Yellow River irrigated area of the Loess Plateau，and to provide a reference for selecting high-quality forage triticale varieties suitable for cultivation in this region.【Method】In 2022，an experiment was conducted in Qingxu County，Taiyuan City，Shanxi Province，to evaluate the adaptability of 11 forage triticale varieties：Gannong No.2，Shida No.1，Jisi No.1，Jisi No.2，Jisi No.3，Jisi No.4，Zhongsi 1048，Zhongsi 3297，Lincao No.2，Jinsicao No.1，and Youneng. The study also comprehensively evaluated the tested varieties in terms of yield，agronomic traits，and nutritional quality using Principal Component Analysis（PCA）.【Result】There are certain differences among the 11 tested varieties of forage triticale in terms of yield，agronomic traits，and nutritional quality. Among them，Jisi No. 3 had the highest plant height（195.00 cm），fresh grass yield （42.47 t/hm2），hay yield（11.37 t/hm2），crude protein yield（1.19 t/hm2），milk net energy（5.56 MJ/kg），milk yield（1 301.48 kg/t），and relative feeding value（88.83%）. Jisi No. 2 showed the lowest dry-to-fresh ratio（0.25）.Shida No. 1 had the lowest acid detergent fiber（ADF）content（38.19%）；while Jinsicao No.1 not only had the lowest neutral detergent fiber（NDF）content（60.76%），but also the highest values for crude protein content（10.74%），total digestible nutrients（53.94%），net energy for gain（2.34 MJ/kg），and relative forage quality（95.42%）. Principal Component Analysis（PCA）revealed that Jinsicao No. 1 and Jisi No. 3 were
the top two best-performing forage triticale varieties based on the comprehensive evaluation.【Conclusion】Jinsicao No.1 and Jisi No.3 are recommended for cultivation as excellent forage triticale varieties in the Yellow River irrigation area of the Loess Plateau. |
