摘　　要：针对东北垄作区免耕播种玉米时存在机具堵塞严重、条带旋耕功耗大、垄上作业稳定性差等问题,设计了驱动圆盘玉米垄作免耕播种机,提出了驱动圆盘破茬、限深轮稳定装置为一体的破茬开沟稳定机构,对本装置的关键参数进行了设计。田间试验结果表明,驱动圆盘玉米垄作免耕播种机通过性能好,破茬能力强。机具破茬深度约为87mm,种肥间距稳定在48mm时能够满足播种要求,播种施肥开沟器在主动圆盘开出的沟槽中进行二次开沟,减少了土壤扰动和动力消耗。与条带旋耕玉米垄作免耕播种机相比,油耗降低8.5%,地表动土量减少约50%。The powered-disc ridge till and no-till planter was designed to solve the problems of straw blocking, high energy consumption of strip rototilling and unstable operation on ridges in current notillage maize planting in ridge tillage areas of northeast China. The machine used the combined device of powered-disc and depth control wheel to cut the stubble, open seed furrow and stabilize in planting, and the key parameters of the device were analyzed and determined. The field experiment showed that the powered-disc ridge till and no-till planter was effective in anti-blocking and cutting stubble. The broken stubble depth was about 87 mm and the separation space between seed and fertilizer was approximately 48 mm, which met the agronomic requirements. Furthermore, the openers seeded and fertilized in the furrow opened by powered disc, thereby decreased soil disturbance and power consumption. The powered-disc ridge till and no-till planter reduced fuel consumption by 8.5 % and soil disturbance by 50 %, respectively compared to the strip-rototilling ridge till and no-till planter.
