Abstract

Abstract: Silage compaction is a crucial step in silage production,and it directly impacts the quality of the silage. Proper compaction not only promotes the rapid onset of lactic acid bacteria fermentation but also establishes a strong foundation for managing the subsequent silage face. This paper briefly described the principle of silage compaction and the method for evaluating compaction (silage density). The factors influencing silage density were analyzed,including the characteristics of the silo and raw materials,as well as the compaction equipment. Eventually,we summarized the latest technical strategies for enhancing silage density to serve as a reference for implementing compaction technology in silage production.

Key words: Silage, Porosity, Compaction, Packing density, Bulk density, Silage density

摘要： 青贮压实是青贮生产中的关键一环。通过影响青贮饲料中固液气三相比例，直接影响青贮饲料的最终质量。充分压实不仅有利于乳酸菌发酵的快速启动，减少原料储存空间，也为后续青贮饲喂面管理奠定基础。本文简述了青贮压实的原理及压实程度(青贮密度)的评价方法；概述了决定青贮密度的影响因素，包括贮存设施、作物特征和压实机械等3个层面；总结了当前提高青贮密度的技术策略，以期为生产中青贮压实的有效实施提供技术参考；并展望了青贮压实技术未来的发展方向。
