| 摘 要： | 为探讨添加剂对不同地区玉米（Zea mays）青贮饲料发酵品质的影响，以绥化（HB）、赤峰市林西（CF）、呼和浩特（H）、河北衡水（HS）和宁夏银川（YC）地区种植的中北410品种作为研究对象，分别设对照组、乳酸菌处理组（0.000 5%）和纤维素酶处理组（0.001 5%），袋装真空青贮，贮藏45 d后取样分析。结果表明，乳酸菌和纤维素酶处理组降低了玉米青贮饲料的pH值和乙酸含量，提高了乳酸含量，改善了青贮饲料的发酵品质和营养价值。添加剂处理组显著降低了玉米青贮饲料NDF、ADF的含量（P＜0.05）；乳酸菌处理组提高了绥化、衡水、银川地区可溶性糖含量，其中银川地区的最高。所有地区添加剂组的青贮玉米发酵品质Flieg等级为优。

| Abstract: | In order to investigate the effects of additives on fermentation quality of corn silage from different areas, North 410 variety planted in Harbin (HB), Chifeng Linxi (CF), Hohhot (H), Hebei Hengshui (HS) and Ningxia Yinchuan (YC) were taken as research subjects. The control group treatments of lactobacillus (0.000 5%) and treatments of cellulose treatments (0.001 5%), silaged in bags under vacuum were set separately and analysis was made after 45 days. The results showed that lactobacillus and cellulase treatments significantly lowered the pH value and acetic acid content, while boviously increased the lactic acid content (P<0.05), and improved the fermentation quality and nutritional value of silage. Additive treatments significantly reduced NDF and ADF contents of corn silage (P<0.05). The WSC contents of lactobacillus treatments in Harbin, Hengshui and Yinchuan were significantly increased (P<0.05) and those in Yinchuan was the highest. The corn silage fermentation quality Flieg level of all areas were excellent. |
