| Abstract: |
| 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. |
