摘要
本试验旨在利用菊芋秸秆来提高玉米秸秆的青贮品质。玉米秸秆与菊芋秸秆按10:0、9:1、8:2、0:10共4个比例进行混贮处理,40d后测定p H值、营养成分和营养价值。结果表明:随着菊芋秸秆比例增大,混贮料的p H值、纤维性营养成分有降低趋势,非纤维性碳水化合物、干物质与中性洗涤纤维48h体外消化率、能值、相对饲喂价值呈上升趋势。综合而言,适量添加菊芋秸秆,具有提高玉米秸秆青贮品质的效果。
The study was conducted to produce high quality silage with Jerusalem artichoke stalk. Corn stalk and Jerusalem artichoke stalk were mixed and silaged at ratio of 10：0,9：1,8：2 and 0：10,respectively. Silages were determined for p H, nutrient content and nutritive value after 40 d ensilage. The results showed as follows： The pH and fibrous nutrients of silage decreased, and non-fiber carbohydrates（NFC）, in vitro true dry matter degradability 48-hour（IVTDMD48）, neutral detergent fiber degradability 48-hour（NDFD48）, relative feed value（RFV） were on rise, with the increasing of Jerusalem artichoke stalk＇s rate. In conclusion, the addition of Jerusalem artichoke straw could improve the quality of corn straw silage.
