不同处理对花生与甜玉米秸秆混合青贮发酵品质的影响
Effect of Various Treatments on Quality of Fermented Peanut Vine/Corn Stalk Silage
摘要
Abstract
Varied mixing ratios of discarded peanut vines (PV) and corn stalks (CS) and/or addition of lactic acid bacteria (LAB) with 3％ sucrose were studied in 2015 to determine their effects on the quality and storage of the resulting silage.The PV:CS ratios of 10 ∶ 0,7 ∶ 3,5 ∶ 5 and 3 ∶ 7 (on fresh weight basis) were applied.Three replicates for each treatment were used.In addition,samples of 3PV∶ 7CS silage were stored in an above-ground cellar for comparison.After 60 d of fermentation,silage quality was analyzed.The results showed that (1) in the 10 ∶ 0,7 ∶ 3 or 5 ∶ 5 PV/CS silage,the lactic acid content increased significantly (P＜0.05),while the pH,butyric acid and ammonia nitrogen decreased significantly (P＜0.05) when LAB and sucrose were added;(2) in the 10 ∶ 0 PV/CS silage with the added LAB and sucrose,the dry matters increased significantly (P ＜ 0.05),and the propionic acid content significantly decreased (P＜ 0.05);(3) in the 5 ∶ 5 PV/CS silage with added LAB and sucrose,the acetic acid significantly decreased (P＜0.05);(4) the 3 ∶ 7 PV/CS silage could deliver acceptable quality without the addition of LAB and sucrose;(5) the 10 ∶ 0 PV silage could be acceptable for applicationsby adding LAB and sucrose;(6) the baled silage appeared to be better than cellar storage for the fermentation.关键词
