The simplified cultivation system for summer corn was characterized by the comprehensive utilization of winter wheat straw, heavy nitrogen fertilizer spreading, precision sowing, chemical weed control and high-level mechanization. Compared to the conventional technology, this new system could hasten crop growth, increase grain yield, improve labour productivity and raise soil organic matter content by 20%, 50%, and 0.0294% respectively while decreasing the production cost by 20%. The physical structure and nutrient-supply capacity of soil were also improved significantly
