A potato planting method comprises the following steps of (a), preparation before planting, (b), planting, (c), field management and (d), harvesting. By using the planting method, planted new Daping level potatoes are high in yield and high in disease resistance, and the shortcoming that the new Daping level potatoes planted by using the traditional planting mode are not high in yield, late blight resistance is not high and the like is overcome. Compared with the traditional cultivation technology, the potato planting method has the advantages that the yield and the quality of potatoes are greatly improved, the yield is improved by 15%, the dry matter content is increased by 12.53%, the reducing sugar content is increased by 20.00%, the soluble protein content is increased by 6.76%, the starch content is increased by 19.07%, and the Vc content is increased by 18.39%; and in 3-5 days before the late blight center diseased or infected plants of the potatoes are found out, the blight of the potatoes can be effectively prevented and cured by using bactericide, and the disease rate is reduced by 27.89%.
