摘　　要： 从玉米定向生长与栽培原理入手,对国内外定向种植机械化现状进行综述;针对研究现状,分析我国玉米定向种植机械化发展中存在的主要问题,以及机械化定向种植涉及的运动控制和批量识别等关键技术。研究结果表明:玉米定向栽植技术具有高产、防病等诸多优点,但目前玉米定向栽植技术多依赖人工操作,费时费力且难以大规模机械化推广;玉米机械化定向种植方面的研究多倾向于定向播种机构的设计,少有玉米粒群定向整列的相关基础理论的研究。就目前玉米机械化定向种植现状,提出应采用多元技术手段开展玉米粒群批量整列机理的研究。 Based on the principle of directional growth and cultivation of maize,the present situation of directional planting mechanization at home and abroad is reviewed.According to current research status,the main problems in the development of maize directional planting mechanization in China are analyzed,and the key technologies of mechanized directional planting involving motion control and batch identification are investigated.The results show that maize directional planting technology has many advantages,such as high yield,disease prevention.At present,the disadvantages of the maize directional planting technology are more dependent on manual operation,which is time and energy consuming and causes difficulties in promoting large-scale mechanization;Researches on mechanized directional planting of maize is more inclined to the design of directional seeding mechanism,and is lack of the research on the basic theory of maize particle swarm directional alignment.In the light of the present situation of mechanized planting of maize,it is suggested that study on the mechanism of batch alignment of maize seeds should be carried out by means of multiple techniques.
