摘　　要：针对我国黄淮海地区马铃薯种植模式特点和农艺要求,设计了一种两垄四行马铃薯播种机。该机主要由机架总成、整地装置、地轮动力驱动装置、施肥装置、排种装置、覆膜装置、开沟器等组成,可一次性完成开沟、施肥、播种、起垄和覆膜等作业。通过对关键零部件的研究分析,确定了其相关结构和工作参数。样机田间试验结果表明,该机性能稳定、作业效果较好,种薯间距合格指数为95.0%,重种指数为2.7%,漏种指数为2.3%,种植深度合格率为91.1%,各行排肥量一致性变异系数为6.5%,总排肥量稳定性变异系数为5.2%,各项性能指标均优于马铃薯播种相关要求。Aiming at the planting pattern characteristics and agronomic requirements of potato in the Huang --Huai--Hai region in China, a double ridge four row type potato planter was designed. The potato plant- er is mainly composed of frame, soil preparation device, ground wheel power transmission device, fertiga- tion device, seed metering device, filming device, and furrow opener et al. It enables a one--stop achieve- ment of ditching, fertilizing, seeding, ridging and film mulching, set strip windrowing procedures. The prototype field test results showed that it stable performance, good operation effects, the spacing qualified index of 95.0%, the multiples index of 2.7%, the misses index of 2.3%, the qualified rate of planting depth of 91.1% , the apiece row discharge fertilizer consistency coefficient of variation of 6.5%, the total discharge fertilizer consistency coefficient of variation of 5.2%, and all the performance indexes of proto- type are better than the indexes of potato planting requirements.
