秸秆问题的分析与研究

课题名称秸秆问题分析与研究摘要摘 要：我国是一个农业大国，我国秸秆年产量大约在7 亿顿。将廉价的农业废弃物重新利用，转化为能源，这项研究本身就极具价值。面对国内秸秆利用的方式途径以及利用率等方面，分析问题以及成因，提出针对性强以及可行性高的措施，因地制宜是解决环境污染以及资源重复利用最好的办法。关键词：秸秆 资源 利用ABSTRACTABSTRACT：China is a big agricultural country, and its annual output of straw is about 700 million tons. The research is of great value in recycling cheap agricultural waste into energy. In the face of the ways and means of straw utilization and utilization rate in China, this paper analyses the problems and causes, and puts forward some measures with strong pertinence and high feasibility. It is the best way to solve environmental pollution and reuse of resources to suit local conditions.KEYWORDS：the straw resources utilizeI目录一、秸秆现状及利用......................................................31.1 秸秆国内利用现状....................................................31.1.1 秸秆直接还田...............................................41.1.2 秸秆间接还田...............................................41.2 秸秆能源化利用......................................................51.2.1 秸秆直燃...................................................51.2.2 秸秆气化...................................................51.2.3 秸秆沼气...................................................61.2.4 秸秆制燃料乙醇.............................................61.2.5 秸秆当做肥料...............................................61.3 秸秆用作饲料........................................................71.3.1 物理法.....................................................71.3.2 化学法.....................................................71.3.3 微生物发酵法...............................................81.4 秸秆用于栽培食用菌农作物.........................................91.5 秸秆的其他...
