摘　　要：东北一熟区是我国农业粮食生产的大粮仓和粮食市场的稳压器,对保障我国粮食安全具有重要的战略意义。但种植结构单一、耕地有机质下降、自然灾害频发、光温水热资源利用效率不高等问题限制了区域农业发展。通过调整种植结构、建立高产高效种植模式、生产生态协同的土壤耕作制度等方式,实现资源优化配置、提升地力,挖掘粮食增产潜力,对实现区域农业绿色发展具有重要意义。The single cropping area in northeast is a big granary and a stable device of grain market in agricul-tural grain production in China,which is of great strategic significance to ensure the food security in China.However,the single planting structure,the decline of soil organic matter,the frequent occurrence of natural disasters and the low utilization efficiency of light,temperature,water and heat resources restrict the develop-ment of regional agriculture.It is of great significance to realize the green development of regional agriculture by adjusting the planting structure,establishing the high-yield and high-efficiency planting mode,and the soil tillage system of production ecology coordination,so as to realize the optimal allocation of resources,enhance the soil fertility,and explore the potential of grain yield increase.
