Effect of mixed sowing ratio on the fermentation quality and aerobic stability of mixed silage of laba bean and silage maize
[Objective]In order to explore the effects of mixed sowing of Dolichos lablab and silage corn(Zea mays)on the quality and aerobic stability of mixed forage silage.[Method]The silage of silage corn after single sow-ing was used as the control(CK).Four mixed sowing ratios of silage corn and Zea mays were set as 1∶1(D1),1∶2(D2),1∶3(D3)and 1∶4(D4).After 60 days of fermentation at room temperature,the nutrients,fermentation quality and aerobic stability of each treatment were determined.[Result]The results showed that the dry matter loss rate and crude protein content of silage corn mixed with Laba bean increased significantly(P<0.05).This study demon-strated that silage corn/Laba bean mixed silage could effectively improve the aerobic stability time,and secondary fer-mentation was less likely to occur in the exposed environment.[Conclusion]Based on aerobic stability time and fer-mentation quality,we suggest that the mixed silage of corn and soybean is more suitable when the mixed ratio is 1∶1.
