【摘要】 本研究采用参与式方法,对全国五个主要玉米生态类型区进行了玉米生产的农民参与式评估(PRA),并通过专家对PRA所获得的玉米生产发展限制因素的分析和参与式学术研讨,对不同生态类型的限制因素进行了重要性排序,在此基础上得出了我国玉米研究的优先序。结果显示,干旱是未来限制我国玉米生产发展的第一限制因素,也是我国玉米科研最优先的研究领域。栽培管理技术和农业技术推广等是近期我国政府在制定相关玉米生产与发展政策时必须考虑的领域。更多还原

【Abstract】 The current research was carried out based on the examination and confirmation of the constraints identified through the PRA surveys for each of five geographical regions and maize production systems in China. All potential physical , biological and institutional constraints that are relevant to each region/production system were considered in the PRA surveys. Maize research, production, and management experts evaluated and judged the data, and draw a conclusion of priorities for maize research and development. Drought is the first constraint limiting maize production, and the first priority in maize research and development. Both production techniques and dissemination system of advanced technology are also important aspects for the government making policy to accelerate the development of maize industry.更多还原
