Abstract: To promote the expanded unilization of forage silage in actual production, this paper analyzed forage silage theory, expounded conditions for making excellent silage, treatment for processing forage grass silage, nutrient loss in the process of silage, second time fermentation and other problems encountered during the process of silage, etc. The paper refined these contents and thoroughly analyzed them from theoretical research perspective. Finally, the paper pointed out the starting point for future silage research expansion was to enhance the research strength on silage additives, and save costs, so as to provide good conditions for the development of grassland animal husbandry.

摘要： 为推动饲草青贮的在实际生产中的扩大利用，对饲草青贮理论进行剖析，分别阐述了制作优良青贮饲料具备的条件、饲草的青 贮处理、青贮过程中的营养损失、二次发酵以及在青贮过程中遇到的一些其他问题等，并分别细化这些内容，从理论研究的角 度深入解析，最后通过分析这些问题，指出未来饲草青贮的研究扩大化的着手点在于加大对青贮添加剂的研究力度、节约成本 开支，以期对草地畜牧业的发展提供良好条件。
