摘　　要：南方林下饲草作为一种新兴林下经济模式,实现了资源和能源的合理利用和林业的可持续发展。对林下饲草进行干燥压块不仅适于保存、运输及商品化,也利于保证干草的品质,提高林农的经济收入。通过三叶草与百喜草的压块影响因素及其压块后营养价值对比研究,得出了三叶草最优保压时间为60～90 s,百喜草最佳保压时间为80～100 s;在饲养价值上三叶草优于百喜草。Southern understory forage,as a new economic model,have achieved the sustainable development and rational use of energy resources and forestry. Understory forage briquetting is not only suitable for storage,transport and commercialization,but also beneficial to the quality of hay and income increases of farmers. This paper explored the different briquetting factors and nutritional value in clover and bahia grass. The experiments showed that the best briquetting holding time for clover was 60 s to 90 s,while bahia grass was 80 s to 100 s,and the clover was better than bahia grass on feeding value.
