In recent years, Jinsha has increased investments on corn harvesting machinery, introduced a variety of combine harvesters, and comprehensively promoted the management at all stages of corn planting and harvesting mechanization process, so as to ensure the completion of the job in the best period and improve the efficiency and effectiveness of corn production. This paper studied on main research methods and measures to promote corn straw returning technology in Jinsha new district through the level of technology, farm machinery and technology policy. Corn straw mechanized returning technology has characteristics of poor quality, poor quality of planting, nitrogen deficiency and pest disease, which should promote the development and application of corn straw returning technology.%近几年，金沙新区加大了玉米收获机械的投入力度，引进了多种联合收获机，全面推进了玉米种植各个阶段的管理及收获全程机械化进程，保证在最佳时期完成各项作业，提高了玉米生产的效率和效益。本文通过技术层面、农机具层面和技术政策层面，研究了金沙新区推进玉米秸秆还田技术的主要方法措施。玉米秸秆机械化还田存在还田质量差、播种质量差、争氮现象、病虫害严重等问题，应推进玉米秸秆还田技术的发展应用。
