摘 要:我国玉米自给压力不断增加,但单产增长却比较缓慢。深入研究农户对玉米新品种技术的需求偏好和农户获取新品种技术信息的渠道,对引导农户科学选种、改善品种技术推广模式、促进新品种培育,提升我国玉米生产水平具有重要意义。为了系统认识我国农户对玉米这一杂交种的品种技术需求和购买行为及存在问题,基于对黑龙江、吉林、河南和山东四省640农户的实地调查数据,系统分析了我国农户对玉米品种技术的需求、农户获取技术信息的来源渠道以及农户在购买玉米种子时面临的主要问题,为今后玉米新品种培育及技术推广等提供一定的参考价值。In China,the pressure for maize domestic supply and self-sufficiency is increasing continuously,but the maize yield per unit area increases very slowly.It is of great significance to understand farmer households' preferences for maize seed technology and channels access to information,so as to guide famers to choose maize seed rationally,improve technology extension pattern,promote breeding of new varieties,and improve the level of maize production in China.In order to fully understand farmer households' demand for new seed technology,their purchasing behaviors and the existing problems,based on a survey dataset from 640 farmer households in Heilongjiang,Jilin,He'nan and Shandong Provinces,this paper systematically analyzes farmer households' requirement for maize variety technology,channels access to sources of technical information,and problems facing farmer households when they are purchasing maize seed,so as to provide reference for new maize variety breeding and technology extension in the near future.
