【摘要】 通过凋萎降低原料作物的水分含量，可提高其干物质含量；和通过使用青贮添加剂，或通过更精细的机械加工使原料作物长度变得更短、更碎等措施，在技术上可以达到提高某种青贮作物的青贮品质的目的。当前青贮调制系统不同程度上依赖于此三种措施。本文例举了一些不同的青贮调制系统的例子，并对添加剂类型和收获机械种类之间的相互作用进行了讨论。更多还原

【Abstract】 Technological improvement of silage quality of a given silage crop can be achieved by lowering the water activity by wilting to a higher dry matter(DM) content,the use of silage additives and by more intensive machine treatment leading to smaller particles or a more lacerated crop Present silage making systems depend to a different extent on these three different actions Examples of different silage making systems are given and interactions between type of additive and type of harvesting machine discussed更多还原
