摘　　要：根据湖北省玉米产需状况及玉米生产发展的限制性因素,探讨了湖北省玉米发展的技术对策,提出了加强技术创新和科技协作。从种植体系革新入手,在平原及部分丘陵区适度扩大玉米种植面积;从栽培技术创新入手,加强玉米种植关键技术的突破,形成定量化、规范化、轻简化栽培技术体系。以利有效提高湖北省玉米的生产水平,增强自给能力,缓解产需矛盾。It is great significance of maize production to protect food security, meet the market diverse needs and optimize the agricultural planting structure in Hubei province. In recent years, maize planting area, unit yield and total production have wonderingly increased, but slowly. There still exists a big gap between supply and demands of corn, and production costs increased dramatically. On the basis of analyzing the situation of maize production and demands, some technical countermeasures of maize development was discussed, furthermore it was proposed to strengthen scientific and technological cooperation and technology innovation. Maize planting area could be moderately expanded through innovation of cropping systems in the plains and some hilly area. Maize yield could be significantly improved through cultivation technological innovation , however, it is necessary to strengthen the key technological breakthroughs, and develop the technology system of the quantitative, standardized, economized and simplified cultivation. It is expected through implementation of those measures to effectively improve the maize production level in Hubei province, enhance self-sufficiency ability of maize and alleviate the contradiction between production and demands.
