摘　　要：基于东北垄作区保护性耕作各类模式的需要,对免耕播种的工艺进行了分析,并提出了对免耕播种机的农业技术要求。设计了滚动圆盘式破茬犁刀、圆盘螺旋线形清茬器,该装置既能提高机具通过性又可保持垄形。采用双圆盘施肥开沟器实现侧深施肥,二个地轮行驶在垄沟中可确保播种机横向稳定。设计的2BG-2型玉米垄作免耕播种机,田间播种作业与检测结果表明该机达到了设计要求。Based on requirement of conservation tillage models in ridge cropping system in northeast area of China,no-tillage planting technology was analyzed.The agriculture-technique demand for no-till planter was put forward.The rolling disc residue cutting coulter and disc spiral ridge cleaning device were used in the proposed planter to improve the planter pass rate and keep ridge shape.Double disc fertilizer was used.Two ground-drive mechanisms were driven to remain the lateral stability of ridge-till planter.Field test results showed that the proposed 2BG-2 corn ridge planting no-till planter met the design requirement.
