摘　　要：[Objective] This paper aimed at exploring technological paths for improving grain productivity based on the conditions and production practice in Henan Province.[Method] The status and dynamics of grain production in Henan Province were analyzed as a whole.[Result] The total production of grain in Henan Province had generally shown a tendency of ascent.Total grain production in Henan Province was 54 370 thousand t,which was 2.5 times of the total grain production in 1978,as 20 974 thousand t.The growth of grain production was more and more relying on the improvement of grain yield per unit area.[Conclusion] This research had provided theoretical basis for the improvement of grain production in Henan Province as well as for the grain production of the whole country.[目的]根据河南省情和生产实际,探讨提高粮食生产能力的技术路径。[方法]对河南省粮食产量的现状与动态进行整体分析。[结果]河南省粮食总产量的变化呈现上升态势。2010年粮食总产5437万t是1978年粮食总产2097.40万t的2.5倍。粮食总产的增长越来越依赖于单产的提高。[结论]该研究为河南省乃至全国粮食增产提供理论依据。
