摘　　要：张家口坝上地区主要经济作物为萝卜、白菜和甜菜,3种作物的播种作业仍是人工点播,生产成本高且效率较低。为实现作物的大面积精量播种,减少耕作劳动量,提高播种效率,设计了一种适用于该地区3种主要经济作物大面积种植的精量播种机,集起垄、整形、镇压、播种、覆土功能于一体,适用于大面积播种作业。田间试验证明,整机结构设计合理,单粒精播率高。As the primary cash crop in Zhangjiakou area,radish,cabbage and beet are seeded by men yet.In order to achieve a large area precision sowing crops and planting of large areas of lower labor input,reducing the amount of labor of farming,improve labor efficiency,this article provide a precise laying seeder for radish,cabbage and beet.The device can ridge,surpress,plant and cover soil,so it is suitable for planting in field.The field trials：the structure of device is reasonable and the rate of single grain precise seeding is high.
