摘要 我国是一个农业大国，人口很多，农民也很多！要实现我国的发展，农业必须要发展。要发展，就必须使用机械化生产。就玉米种植来说就有很多问题。因此，实现机械化育苗栽植，提高劳动生产率，是推广玉米育苗栽植技术，获得玉米高产，提高玉米生产经济效益的关键环节。 栽植机械是玉米育苗栽植技术的关键设备。所以必须选择好的机械，那样就能事半功倍！实践证明，玉米机械化育苗栽植是一项系统工程，必须将育苗技术、机械化栽植和田间管理三者结合起来，才能获得玉米稳产高产和较好的经济效益，在更大范围内推广应用玉米育苗栽植。此次秧苗移栽试验台的设计就是解决以上问题，完成一套适合于工厂育苗的秧盘播种系统，系统由育苗盘变速传动装置、播种装置、铺土装置、喷水及微机控制装置组成。此机械装置能在室内进行秧苗的机械育苗。通过在室内的育苗以及以后的移栽，就能提高产量，对我国农业的发展大有益处。 关键词：栽植技术，栽植机械，玉米育苗，秧盘播种系统 the Earth Equipme
