甘蔗稍绿汁发酵液对菌糠发酵品质的影响

为探索菌糠有效的保存方法，本试验采用甘蔗稍绿汁发酵液为添加剂，研究不同的开封时间及甘蔗稍绿汁发酵液对菌糠青贮饲料发酵品质的影响。试验设2% 绿汁发酵液组和对照组（等量蒸馏水），采用青贮袋抽真空密封贮存，放置室温。分别在发酵第1，3，7，15，30和60 d开封，测定发酵品质。每个处理5个重复。结果表明，甘蔗梢绿汁发酵液能够显著（P<0.05）降低的菌糠青贮饲料的pH值和显著（P<0.05）提高青贮饲料的乳酸含量，有效的促进菌糠发酵进程，保存其营养物质。菌糠青贮发酵饲料最佳的开封时间是15 d，最迟不宜超过30 d。

Effects of Previously Fermented Juice of Sugarcane Top on the Fermentation Quality of Fungus Chaff Silage

In order to study the effective storage method of fungus chaff, the fermentation quality of fungus chaff silage by adding Sugarcane Top Previously Fermented Juice (STPFJ) with different storage times was evaluated in this experiment. The fungus chaff was separately ensiled with 2% STPFJ and equivalent amounts of distilled water (control). Each fungus chaff silage treatment was ensiled in five vacuums for 1,3, 7, 15, 30 and 60 days. The results showed that the pH value of the silages was significantly decreased (P<0.05) and the lactic acid content was significantly increased (P<0.05) by STPFJ. The experimental results proved the effectivity of STPFJ in the fungus chaff fermentation process to save its nutrients. The best opened time in fungus fermentation was 15 days, no more than 30 days.
