1、青貯菌劑對(duì)甜高粱秸稈與酒糟青貯品質(zhì)U!的影響岳麗葉凱再吐尼古麗?庫(kù)爾班王卉山其米克涂振東新疆農(nóng)業(yè)科學(xué)院生物質(zhì)能源研究所摘要:【目的】研究青貯菌劑對(duì)甜高粱秸稈與酒糟品質(zhì)的影響,為甜高粱酒糟飼料化利用提供理論依據(jù)。【方法】以甜高粱秸稈和酒糟為青貯原料,通過感官得分、理化指標(biāo)變化評(píng)價(jià)甜高粱青貯的品質(zhì),研究青貯菌劑對(duì)甜高粱秸稈青貯過程中pH值、粗纖維、總酸、總糖、干物質(zhì)等成分的影響?!窘Y(jié)果】甜高粱酒糟的青貯品質(zhì)略低于秸稈,等級(jí)為II級(jí)尚好,具有作為青貯原料的潛力;添加菌劑組甜高粱秸稈的總糖和述原糖含量分別比對(duì)照組顯著提高,粗纖維比對(duì)照組降低了21.4%,青貯菌劑可以提
2、高總酸含量、降低青貯pH值?!窘Y(jié)論】青貯菌劑可以提高甜高粱秸稈和酒糟的發(fā)酵品質(zhì)、改善營(yíng)養(yǎng)品質(zhì),延長(zhǎng)秸稈和酒糟的貯存吋間。關(guān)鍵詞:甜高粱;酒糟;青貯菌劑;品質(zhì);作者簡(jiǎn)介:岳麗(1990-),女,新疆人,助理研究員,碩士,研究方向?yàn)樯锬茉矗?E-mail)Yueli4467@163.com作者簡(jiǎn)介:涂振東(1962-),男,湖北人,研究員,研究方向?yàn)樯镔|(zhì)能源的開發(fā)與綜合利用,(E-mail)tzhd919@126.com收稿日期:2017-07-15基金:基金項(xiàng)目:現(xiàn)代農(nóng)業(yè)產(chǎn)業(yè)技術(shù)體系“谷子高粱技術(shù)體系一秸稈與副產(chǎn)物綜合利用”(CARS-06-13.5-A5)
