Efficient simple mulching cultivation method for sweet potatoes

The invention relates to a mulching cultivation method for sweet potatoes, in particular to an efficient simple mulching cultivation method for sweet potatoes, and belongs to the technical field of cultivation methods. The method includes the five steps, namely ridging, covering with black mulch, perforating and watering, planting seedlings, and closing holes. According to the method, the black mulch is used for covering, a perforating watering mulch-piercing device is used for sweet potato planting, potato seedling inserter rods are applied to the mulching cultivation of sweet potatoes, the process of mulching cultivation is shortened from eight steps to five steps, the operating process of sweet potato cultivation is simplified, and accordingly labor intensity is reduced; the black mulch which has the function of natural weed inhibition is used for covering, pesticide spraying is avoided, and accordingly input labor is less, pollution by the pesticides is avoided and green foods can be produced; perforating
