摘　　要：青贮饲料开袋后取用不及容易产生二次发酵,降低青贮饲料的品质。试验以山梨醇钾和苯甲酸钠为主体,通过5种不同方案对袋装青贮保鲜处理效果的反复试验,确定了山梨醇钾36 g+苯甲酸钠66 g+20 kg稀释液的保鲜剂优选方案,使用后能显著抑制青贮饲料二次发酵,提高青贮饲料的利用率。If the silage is not used up after opening the bag,it is easy to cause secondary fermentation and reduce the quality of the silage.In the experiment,potassium sorbitol and sodium benzoate were used as the main body,and five different schemes were used to repeatedly test the effects of bagged silage preservation.This determined the optimal preservative scheme of potassium sorbitol 36 g+sodium benzoate 66 g+20 kg diluent.This can significantly inhibit the secondary fermentation of silage after use,and improve the utilization rate of silage.
