During the whole reproductive period of a potato, the type and amount of nutrients it needs are different due to different stages of growth. The seedlings absorbed little, the absorption at the hair growth stage increased rapidly, reached the highest peak in the early stage of tuberculosis, and then the amount of fertilizer absorption decreased rapidly. The three elements of nitrogen (N), phosphorus (P2O5), and potassium (K2O) were absorbed at each growth stage. According to the percentage of the total absorbed fertilizer, the germination to emergence period was 6.0%, 8.0% and 9.0%, and the hair growth period was 38.0. %, 34.0%, 36.0%, and the potato period was 56.0%, 58.0%, and 55.0%. Among the three factors, the uptake of potassium by potato was the most, followed by nitrogen and phosphorus. According to the test, for every 1000kg tubers produced, it is necessary to absorb 5~6kg of nitrogen, 1~3kg of phosphorus pentoxide and 12~13kg of potassium oxide.
