摘　　要：秸秆资源由于其特殊的结构,导致其在被反刍动物采食后,利用率较低,造成了资源的浪费,以及导致了甲烷排放对环境的污染。了解农作物秸秆在瘤胃中降解的详细时空程序,制定相对应的秸秆饲料化处理方案,是解决此类问题的重要前提。文章论述了国内外秸秆资源利用的现状及问题、农作物秸秆在瘤胃中降解的时空程序、提高秸秆饲料化的利用方案以及甲烷减排的关键技术,为解决农作物秸秆利用效率中存在的问题提供一些思路。Due to its unique structure,straw resources have a low utilization rate after being fed by rumi⁃nants,resulting in resource waste and environmental pollution caused by methane emissions.Understand⁃ing the detailed spatiotemporal process of crop straw degradation in the rumen and developing corre⁃sponding straw feed treatment plans is an important prerequisite for solving such problems.The article discussed in detail the current situation and problems of straw feed utilization at home and abroad,the spatiotemporal program of crop straw degradation in the rumen,the utilization plan for improving straw feed utilization,and key technologies for methane emission reduction,providing some ideas for improving the efficiency of crop straw utilization.
