The invention provides soil for cultivating potato seedlings and a preparation method of the soil, and relates to the technical field of potato planting. The soil for cultivating the potato seedlings is divided into three layers: the upper layer is vermiculite, the middle layer is a granular culture medium, and the bottom layer is nutrient soil; the granular culture medium is composed of straw, plant ash and slag; and the nutrient soil is composed of soil and fertilizer. The nutrient soil of the bottom layer is composed of soil and fertilizer and provides field planting conditions and nutrient substances for growth and development of the potato seedlings; the middle layer is the granular culture medium composed of the straw, the plant ash and the slag, the granular culture medium is used for partially replacing the vermiculite to reduce the cost, and after the waste straw, plant ash and slag are prepared into the granular culture medium, residual nutrient substances, hormones and the like can be reused; and t
