The invention relates to a high-yield potato planting method which comprises the following steps: step 1, selecting sandy soil in which cereal crops are planted in previous crops for planting, deeply ploughing 7-8 inches in early autumn, and controlling the pH value of the soil to be 5.5-6.5; step 2, selecting potato tubers which are smooth and tender in epidermis, bright in
skin color, free of diseases and pests and free of freezing injury as seeds,
cutting the potatoes into blocks, stacking the potatoes in a ventilated place, and covering the potatoes with fine sand with the thickness of 5-10cm; according to the method, soil is deeply ploughed during planting, it is ensured that the soil is ploughed to be about 30 cm deep, growth and development of potatoes are facilitated, sufficient
nutrient supply is provided, potato seeds are planted through top buds, the emergence rate is increased, good conditions are created for high yield of the potatoes, and the thickness of a soil layer can be increased by adopting a ridging planting means; the method improves the air permeability and heat preservation of the soil, and timely carries out ridging to increase the height and width of ridges, so that larger growth space and
nutrient supply can be provided, and the expansion and development of the potatoes are facilitated.
