秸秆是农作物的重要副产品,更是非常重要的可供开发和综合利用的可再生资源。作为我国粮食主产区,长春市生产大量玉米、水稻、大豆等农作物秸秆。本论文以2005-2011年间长春市年平均粮食产量为基础,测算长春市农作物秸秆总量及可收集量,并对该地区农作物秸秆综合利用情况进行了简要评价。本文认为:要发展好农作物秸秆产业应重新认识和评估农作物秸秆的资源性特点,要整理和评估已建及在建农作物秸秆利用项目,加大农作物秸秆综合利用技术创新体系建设力度,继续扶持农作物秸秆产业化发展,形成协调、健康、有序的产业发展格局。
Straw is an important by-product of crops and is a very important renewable resource for development and comprehensive utilization. As China’s main grain producing areas, Changchun produces a large amount of crop straw such as corn, rice and soybean. Based on the annual average grain yield of Changchun City from 2005 to 2011, the total amount of crop stalks and the amount of straw collected in Changchun were calculated. The comprehensive utilization of crop stalks in this area was briefly evaluated. This paper argues that in order to develop the crop straw industry, we should re-understand and evaluate the resource characteristics of crop straw. We should organize and evaluate the straw utilization projects of existing and under construction crops, increase the construction of technological innovation system for comprehensive utilization of crop straw, and continue to support crops Straw industrialization, the formation of a coordinated, healthy and orderly pattern of industrial development.
