为探讨绿汁发酵液、四蚁酸铵及绿汁发酵液+四蚁酸铵对“大力士”饲用甜高粱青贮品质的影响,以“大力士”饲用甜高粱全株为青贮原料,设对照、绿汁发酵液、四蚁酸铵和绿汁发酵液+四蚁酸铵4个处理,常温下贮存60 d后取样,测定其发酵品质与化学成分.结果显示:添加绿汁发酵液、四蚁酸铵及绿汁发酵液+四蚁酸铵,均可显著降低“大力士”饲用甜高粱青贮饲料的pH和气体损失率(P＜0.05),提高干物质回收率、粗蛋白和水溶性碳水化合物含量(P＜0.05).表明添加绿汁发酵液、四蚁酸铵及绿汁发酵液+四蚁酸铵均可显著改善“大力士”饲用甜高粱的青贮品质.%This study was carried out to evaluate the effects of adding fermented green juice and foraform on the fermentation quality of Hunnigreen forage sorghum silage. The treatments were as follows ;control. PFJ addition, foraform addition, PFJ +foraform addition on the fresh weight basis of Hunnigreen forage sorghum, respectively. The materials were ensiled at normal temperature and opened 60 days later . Then the fermentation quality and chemical composition of silages were analyzed. Adding PFJ , foraform and PFJ+ foraform could significantly decrease pH ,ammonia nitrogen content and the lost of gas and improve the crude protein content,water soluble carbohydrate and dry matter recovery(P<0. 05). The results showed that adding PFJ , foraform and PFJ + foraform could significantly improve fermentation quality of Hunnigreen forage sorghum silage.
