| Abstract: | Key technologies of corn production in the U.S. were introduced, including the selection of corn varieties for ripe period, farming operation and corn growing process, tillage system and soil preparation, irrigation and fertilization, cover crop and precision agriculture. Based on the comparative analysis of China and U.S. on climatic conditions and development process of corn production, some proposals in such aspects as change of goals in corn production were put forward from high yield to high yield and high efficiencies(natural resource use and economics), simplifying farming procedure, and promoting the full mechanization from planting to harvest, with emphasis on mechanized harvest of grain. |
