为解决我国东北、西北、华北等北方旱作地区中耕作物的精密播种,由中国农机研究院、石家庄市农机厂、河北省机械研究所、陕西省农机研究所、吉林省农机研究所、吉林工业大学等单位组成的气力式精密播种机联合设计组研制了2BJ—4/6气力式精密播种机。该机可以对玉米、大豆、高粱、球化甜菜籽,脱绒棉籽等作物的种子进行单粒精密播种,也可以在麦茬地上直接播种玉米。该机可一次完成开沟,下种、覆土、镇压、起垄等项作业,同时施种肥。该机主要性能指标达到国外
In order to solve the precision sowing crops cultivation in northeast, northwest, north China and other northern dry farming areas, by the China Agricultural Machinery Research Institute, Shijiazhuang City Agricultural Machinery Factory, Hebei Machinery Institute, Shaanxi Provincial Agricultural Machinery Research Institute, Jilin Province Agricultural Machinery Research Institute, Jilin Industrial University and other units composed of precision pneumatic planter joint design team developed 2BJ-4/6 pneumatic precision planter. This machine can carry out precise grain sowing on the seeds of crops such as corn, soybean, sorghum, pelleted beetroot, de-cottonseed and so on. It can also sow corn directly on the stubble field. The machine can complete a ditch, under the kind of, soil cover, cracks, ridging and other operations, while the application of fertilizer. The main performance indicators to reach abroad
