玉米秸秆收贮高效资源化利用模式分析

积极开发玉米秸秆低成本、高质量收贮模式,有效提高资源化利用水平,是推行农作物秸秆以农用为主、多元综合利用的重要途径。本研究在内蒙古自治区以玉米秸秆榨汁存贮模式为研究对象,基于实际收贮利用成本、秸秆产品收益对该模式资源化利用水平进行分析,结果表明目前该模式具有良好的经济效益,成本费用收益率约为6.70%,销售利润率约为6.30%,并且在收贮过程中能够有效降低秸秆中干物质、糖分和水分的流失,是一种高效资源化收贮利用模式。同时,结合该收贮模式在资源化利用方面的优势及我国东北地区玉米秸秆利用现状进行该模式在当地推广可行性探究表明,该模式具有一定程度上的推广前景。

Analysis of High Efficiency Resource Utilization Pattern of Corn Straw

Actively developing low-cost high-quality utilization of corn straw, and effectively enhancing corn straw resource utilization rate is very important to promote the use of crop straw in agricultural and comprehensive processing. This study armed at the corn straw juicestorage and utilization pattern in Inner Mongolia Autonomous Region, and analyzed the cost-benefit of corn strawproducts based on the actual cost of storage and utilization. The processing and utilization model could effectively reduce the dry matter, sugar and water losses in corn straw, with good economic benefits. The ratio of profits to cost was about 6.70% and the sales margin was about 6.30%. Combined with the advantages and disadvantages of the collection and storage mode in the utilization of resources and the status quo of the utilization of corn straw in Northeast China, we suggest that the corn straw resource utilization model is feasible in northeast region.
