The invention discloses a shallowly-growing directional cultivation method for Chinese yam, which belongs to the technical field of Chinese yam planting. The cultivation method comprises the following steps of: treating potato seeds, preparing soil, placing in a shallowly-growing groove and a matrix, applying a base fertilizer, planting, and carrying out field management and pest control. According to the cultivation method disclosed by the invention, the problems of need of deep groove planting and deep excavation recovery, labour and time waste, and extreme liability to damage tubers of the traditional Chinese yam planting technology are solved; by applying a shallowly-growing directional cultivation technology for Chinese yam, deep excavation is avoided during planting, Chinese yam is plant in the previously transversally-buried shallowly-growing groove, and surface soil is pushed aside only by a simple tool or by both hands during recovery. The method has the characteristics of being wide in suitable soil range, fast in tuberization, and easy to harvest, and is capable of achieving the purposes of high yield, high quality and high efficiency of Chinese yam cultivation.
