The mineral nutrients with the most absorption of potato are potassium, nitrogen and phosphorus, followed by a small amount of calcium, magnesium, sulfur, iron, boron, zinc, manganese, copper, molybdenum, and sodium. The demand for nitrogen, phosphorus, and potassium was different at each growth stage, and the seedling period was very small, accounting for 19%, 17.5%, and 17% of the total; the demand for hair growth was soaring, accounting for 56% of the total, respectively, 48.5 %, 49%, the main distribution of stems and leaves, accounting for 67%, followed by tubers accounted for 33%; potato demand accounted for 25% of the total, 34%, 34%, mainly tubers, accounting for 72%, and 28% of stems and leaves. For absorption of calcium, magnesium, and sulfur, the seedling period is extremely low, the rate of absorption is also slow, and the period of hair growth is sharply increased, and it slows down after the potato period. The potato absorbed very few trace elements, yielded 1340 kg/mu of tuber, absorbed 2.9 g of copper, manganese 2.8 g, molybdenum 0.05 g, and zinc 6.6 g. Most of the nitrogen, phosphorus, and potassium needed by potatoes need to be supplied by basal and topdressing fertilizers, except for the soil. Under normal circumstances, for every 1,000 kilograms of tubers produced, 4–6 kg of pure nitrogen, 1.66–1.85 kg of phosphorus pentoxide, and 8–10 kg of potassium oxide are absorbed from the soil.
