Forage yield and nutrient value in the mixture of triticale and legume in the farming-pastoral ecotone of Xiahe
[Objective]To establish the optimum mixture model of triticale and legumes in the farming-pastoral ecotone of Xiahe.[Method]This research was conducted to study the production performance and nutrition quality of three kinds of legumes (Canadian forage peas,Qinghai common vetch and 'Lvjian No.1') mixed with triticale vari-ety 'Gannong No. 2 at different ratios (0∶100,20∶80,30∶70,40∶60,50∶50,60∶40,70∶30,80∶20,100∶0),respec-tively.[Result]The combination of Gannong No. 2 and Canadian forage peas,had the lowest average ADF content (31.57％)and highest comprehensive evaluation value (0.954). The triticale height (137.00 cm),legume forage height (121.78 cm) and EE content (2.76％) were the highest in the combination of Gannong No. 2 and 'Lvjian No.1' vetch,.From the signal factor of mixed ratios,the three kinds of legumes mixed with Gannong No.2 at a ratio of 30∶70,both the average hay yield (13.7598 t/hm²) and the comprehensive evaluation value (0.687) were the highest. In contrary,from the interaction of mixture combination and ratios,Qinghai common vetch mixed with Gan-nong No. 2,at a ratio of 30∶70,hay yield (15.69 t/hm²) was high and comprehensive evaluation value was the high-est (0.706) while at a ratio of 20∶80,the hay yield was the highest (16.45 t/hm²) and comprehensive evaluation value was high (0.633).[Conclusion]Therefore,in the farming-pastoral ecotone of Xiahe,the best mixture model was Qinghai common vetch mixed with Gannong No. 2 at a ratio of 30∶70 or 20∶80.
