摘要
从玉米品种熟期选择、农事操作及玉米生育进程、土壤耕作类型与整地、灌溉与施肥、绿色覆盖作物及精准农业技术等方面介绍美国玉米生产的技术特点,并比较分析中美玉米生产的气候条件、生育进程差异,提出高产与高效协同发展、简化农事操作、推进子粒收获等建议。
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.
