Studies on the production performance and nutritional value of triticale and pea mixture grassland in central Gansu Province
[Objective]This study aimed to identify the most suitable triticale varieties for mixed sowing with pea in central Gansu Province.[Method]Triticale(×Triticale Wittmack)line C23,triticale variety Gannong No.2 and pea(Pisum sativa)were used as experimental materials in this study.The forage yield and nutritional quality of monocropping triticale variety Gannong No.2,mixed sowing of triticale variety Gannong No.2 and pea,and mixed sowing of triticale line C23 and pea-were evaluated across three regions in Linxia County.[Result]The effect of legume-grass mixtures was better than that of monoculture.When triticale variety Gannong No.2 and pea were mixed sowing,regardless of the experimental sites,the crude protein(CP)content(12.87%)and comprehensive evaluation value(0.77)were the highest.When planting at the Anjiapo town experimental site,regardless of the planting patterns,the comprehensive evaluation value(0.60)was the highest.From the interaction of the experimen-tal sites and planting patterns,the CP content(13.87%)and comprehensive evaluation value(1.00)of the triticale variety Gannong No.2 and pea mixed sowing were the highest in Manlu town experimental site,and the hay yield(7.15 t/hm2)was also higher.[Conclusion]The experimental sites of Manlu town and Anjiapo town are optimal for the triticale variety Gannong No.2 and pea mixed sowing,while Yinji Town is better suited for mixed sowing of triti-cale line C23 and pea.
