【摘要】 秸秆中含有丰富的纤维素、半纤维素、木质素和氮、磷、钾、钙、镁等微量营养元素，是一种很好的可再生清洁生物质能源。我国作为农业大国，每年都会产生大量秸秆。在第四次工业革命“低碳经济”的大趋势下，如何将秸秆生物质循环利用成为人们日益关注的问题。因此，从还田、制取沼气、生物质燃料、培育食用菌、生产工业原料、发电等方面介绍了我国秸秆生物质循环利用的现状、发展前景以及存在的问题。更多还原

【Abstract】 Straw is rich in cellulose, hemicellulose, lignin, nitrogen, phosphorus, potassium, calcium, magnesium and other micronutrients,which is a good renewable clean biomass energy. As a large agricultural country, China produces a large amount of straw every year. Under the general trend of “low-carbon economy” of the fourth industrial revolution, how to recycle straw biomass has become an increasingly concerned problem. Therefore, the current situation, development prospects and existing problems of straw biomass recycling in China are introduced from the aspects of returning farmland, producing biogas, biomass fuel, cultivating edible fungi, producing industrial raw materials, power generation and so on.更多还原
