农作物秸秆作为生物质能资源的主要来源之一,是指在农业生产过程中,收获了小麦、玉米、稻谷等农作物以后,残留的不能食用的茎、叶等副产品。我国是农业大国,作物种类较多,具有丰富的秸秆资源,其中稻谷、小麦、玉米、棉花和油菜等主要农作物秸秆占很大比重。大力开发利用秸秆等生物质能,既是我国开拓新的能源途径,缓解能源供需矛盾的战略措施,也是解决“三农”问题,保证社会经济持续发展的重要任务。 Crop straw as one of the main sources of biomass energy resources refers to the by-products such as stems and leaves that can not be eaten after harvesting crops such as wheat, corn and rice in the process of agricultural production. China is a big agricultural country with more types of crops and abundant straw resources, among which the major crop straws such as rice, wheat, corn, cotton and rapeseed account for a large proportion. Vigorously developing and utilizing biomass energy such as stalks is not only a strategic measure for our country to explore new energy sources and alleviating the contradiction between supply and demand of energy, but also an important task for solving the “three rural issues” and ensuring sustainable social and economic development.
