The invention discloses a solar power driven yam planter which comprises a high-efficiency solar cell panel, a group of battery energy storage system, an electric energy management system, a group ofbrushless motor variable speed drive systems, a track driving system, a steering wheel, a group of furrow opener, a group of mark scrapers, two groups of covering devices composed of covering discs and covering arc plates, a rack and a worktable. The solar energy is converted into electric energy to drive the motor to rotate so as to drive the vehicle body to move forwards by the solar cell panel,and the storage battery is used for supplying power to the vehicle body under the condition that the power supply of the solar cell panel is insufficient. The steering wheel is used for enabling themachine to turn round in the field and to run and steer on a field road, furrows are formed by the furrow opener, the mark scrapers are used for scraping marks so as to place yam tubers in the openedfurrows according to specific row spacing, and the covering devices cover the placed yam tubers so as to provide an excellent growth environment. The labor intensity and labor time of workers are greatly reduced.
