中文摘要: 随着国家草原生态补助奖励机制和草原牧区畜牧业经营方式转型升级政策的落实,天然草地牧草青贮技术作为支撑集约化养殖和饲草长期战略储备的重点技术日益受到重视。但是,在实践中该类青贮饲料优质率低,开窖使用时稳定性差等问题,严重影响了该技术的推广应用。本项目针对前期研究重工艺,轻机理的不足,拟定以呼伦贝尔典型草原区天然牧草为研究材料,从牧草群落组成、原料可溶性碳水化合物含量、缓冲能水平以及附着乳酸菌对青贮发酵过程和青贮品质的影响入手,深入研究天然牧草青贮饲料中的各类营养物质在厌氧发酵和有氧保存阶段对本研究采用的生物和化学调控制剂的响应机制,为调制优质天然牧草青贮饲料和安全利用提供可借鉴的依据。

英文摘要: The natural forage silage technique has been increasing attention as a key technique to support intensive feeding management and forage strategic reserve accompanied by the national policies of national grassland ecological subsidy incentives and changes of grassland-livestock management models. However, the lower quality and stability of silage products seriously affect the application and production. Based on above situation, the project will research the response mechanism of biological and chemical on forage composition, soluble carbohydrate content, buffer energy, and the amount of lactic acid bacteria of forage quality under anaerobic fermentation and aerobic storage in the typical grassland of Hulunbeier region. The aims are to provide referential basis for processing forage silage and safety utilization.
