中文摘要：

阐述了移栽农艺对中国农业发展的重要意义,指出移栽机特别是钵苗移栽机将是大幅度提高粮食单产的农机装备,说明了移栽对北方寒地粮食增产和农民致富的积极作用。简述了国际移栽装备的发展史,提出了移栽机械发展一般经历3个阶段：初级阶段的滑道机构;中级阶段的杆机构;高级阶段的回转机构。综述了国内外移栽机械发展现状和研究水平,对其发展方向做出了展望,强调钵苗移栽研究若要进入回转机构研究阶段,研究人员须掌握机构学等系列理论基础、计算机专业知识和熟练掌握现有的市场软件,以及具备对这些市场软件二次开发的能力。对当前国内一些移栽装置重要发展方向提出了系列建议。

英文摘要：

This paper describes the significance of transplanting agronomy for the development of China agriculture, and points out that the transplanting machine, especially the potted-seedling transplanting machine, will be the one to substantially increase the per unit area yield of grain and play the positive role of transplanting for increasing grain production in North China Cold Area and promoting farmers to get rich. After reviewing the history of transplanting equipments in the world, it is indicated that the development of transplanting machinery is generally divided from low to high into three stages, the slide- mechanism stage, bar-mechanism stage, and rotary-mechanism stage. This paper analyzes the development status and research level of the transplanting machinery at home and abroad, and forecasts the prospects of development trend. It is emphasized that in order to enter the rotary-mechanism stage of the potted-seedling transplanting machinery, the researchers must master the mechanism and related theories, computer knowledge and the operation, and secondary development skills of commercial software. The paper also puts forward a series of proposals on some current domestic important development trend.
