耧车
战国时期（公元前475年～公元前221 年）就有了播种机械。耧车是由种子箱、耧管组成那个，但最早的耧车因播种幅宽不一，行数不同，汉武帝时，官员赵过在一脚耧和二脚耧的基础上，创造发明了能同时播种三行的三脚耧，以人力或畜力为牵引动力，一人扶耧播种，这项发明创造, 极大的促进了古代农业的发展。耧车也是现代播种机的始祖。
In Warring States Period (475 BC-221 BC), seeding machines occurred. Ancient animal drawn seed sower is regarded as the ancestor of modern sowers. However, original sowers are different in rows since their varied seeding widths. During the period of Emperor Hanwu, an officer named Zhao Guo invented a tir-feet sower based on single-foot sower and dual-feet sower, and new tool can seed in three rows at the same time, thus to prompt the ancient agriculture.
