河南省小麦—玉米两熟生产现状与均衡增产技术（英文）

摘要

[Objective] This paper aimed to analyze the production status and balanced yield-increasing technology for wheat-corn double cropping production in Henan Province. [Method] Natural conditions in Henan Province, status and potential of wheat-corn double cropping production were explored, and factors affecting wheat-corn double cropping production capacity were analyzed. [Result] Yield-increasing of grain in Henan Province is achieved mainly depending on the increase of wheat and corn production, and corn has a relatively large yield-increasing potential. Research on high-yield and efficient technology for wheat-corn double cropping production in Henan Province has laid the technical basis for balanced yield-increasing of annual double cropping production. [Conclusion] This study provided a theoretical basis for grain production in Henan Province and a reference for the national food production.%[目的]对河南省小麦-玉米两熟生产现状与均衡增产技术进行分析。[方法]探讨河南省自然条件和小麦-玉米两熟生产现状与潜力,分析影响小麦-玉米两熟生产能力的因素。[结果]河南省粮食的增长主要是靠小麦、玉米产量的增长实现的,而玉米增产潜力较大。河南省小麦-玉米两熟一体化高产高效技术研究,为周年两熟均衡增产奠定了技术基础。[结论]为河南省粮食增产提供理论依据,对全国粮食生产也存在借鉴意义。
