| 中文摘要: |
| 研究5个饲用小黑麦（× Triticosecale Wittmack）品种（‘甘农2号’，‘甘农3号’，‘甘农4号’，‘甘农7号’，‘藏饲1号’）分别与‘甘农1号’黑麦（Secale cereale ‘Gannong No.1’）以不同混播比例（100∶0, 90∶10, 80∶20, 70∶30, 60∶40, 50∶50, 0∶100）进行立体种植的生产性能和营养价值研究，为陇东旱塬区秋播小黑麦和黑麦立体种植提供理论依据。结果表明，陇东旱塬区B1（‘甘农2号’小黑麦与‘甘农1号’黑麦混播）和B2组合（‘甘农3号’与‘甘农1号’黑麦混播）以不同比例混播的平均干草产量显著高于B5（‘藏饲1号’小黑麦与‘甘农1号’黑麦）组合，分别提高21.68%和18.80%；不同小黑麦品种与‘甘农1号’黑麦以A6（50∶50）的比例混播时，平均干草产量显著高于小黑麦单播，且高于黑麦单播，增幅分别为22.94%和3.05%；基于干草产量、营养价值和倒伏率的综合评价表明，‘甘农3号’小黑麦与‘甘农1号’黑麦以70∶30的比例混播进行立体种植时效果最好，适宜在陇东旱塬区及其他气候相似区推广种植。 |

| The production performance and nutritive values of 5 autumn sown triticale (× Triticosecale Wittmack) varieties (‘Gannong No.2’, ‘Gannong No.3’, ‘Gannong No.4’, ‘Gannong No.7’, ‘Zangsi No.1’) mixed with rye (Secale cereale L.) variety ‘Gannong No.1’ at different mix\|sowing rates (100∶0, 90∶10, 80∶20, 70∶30, 60∶40, 50∶50, 0∶100) were studied to lay a theoretical foundation for the stereoscopic cultivation mode of autumn sown triticale with rye in the Longdong rainfed plateau area. The results showed that the average hay yield of B1 (‘Gannong No.2’ triticale mixed with ‘Gannong No.1’ rye) and B2 combination (‘Gannong No.3’ triticale mixed with ‘Gannong No.1’ rye) in different proportions in the Longdong rainfed plateau area was significantly higher than that of B5 combination (‘Zangsi No.1’ triticale mixed with ‘Gannong No.1’ rye), which was 21.68% and 18.80% higher, respectively. When different triticale varieties were mixed with ‘Gannong No.1’ rye at a 50∶50 sowing rate, the average hay yield was significantly higher than that of triticale single sowing, and higher than that of rye single sowing, with an increase of 22.94% and 3.05%, respectively. Through comprehensive evaluation based on hay yield, nutritional value, and lodging rate showed that ‘Gannong No.3’ triticale mixed with ‘Gannong No.1’ rye at a 70∶30 sowing ratehad the best effect when used for stereoscopic cultivation. It is recommended for popularization and planting in the Longdong rainfed plateau area and other areas with similar climates. |
