摘　　要：从品种布局、土壤耕作与施肥、气候、机械及土地流转5个方面入手,通过文献查阅、实地调查、委托调查、专家访谈、农户访谈、电话咨询等方式相结合,以吉林省为主要调查区域,并将其划分东、中、西部,对限制东北春玉米密植高产高效和机械化收获的关键因素进行详细分析。充分结合目前东北地区春玉米种植与收获过程中存在的种种问题,具体提出相应的解决对策,助推东北春玉米密植高产高效与全程机械化采收进程。This article starts from five aspects of variety layout, soil tillage and fertilization, climate, machinery and land transfer, taking Jilin province as the main survey area, and divide it into east, middle and west, a detailed analysis was made of the key constraints factors on the high yield, high efficiency and mechanized harvesting of spring maize in Northeast China. The problems existing in the planting and harvesting of spring maize in Northeast China are fully combined, and the corresponding solutions and countermeasures are proposed, so as to boost the entire mechanized harvesting process of northeast spring maize.
