Garlic has high requirements for N, P, and K fertilizers throughout the growing season, but its demand varies during different growth periods. Nitrogen is an important nutrient needed for the growth of garlic. The medium-yield garlic field absorbs 19.5 kilograms of pure nitrogen per acre. In addition to a slightly larger absorption during the elongation period of garlic sprouts, it is basically absorbed in the whole growth period. Phosphorus requires less nitrogen than nitrogen, but it is essential for promoting root development, differentiation and growth of garlic sprouts and garlic, with an absorption of 5.1 kilograms per mu, and 62% of the absorption is in the elongation period of garlic sprouts, while in the seedlings The absorption of garlic and garlic was 17% and 21%, respectively. Potassium, in the three major nutrient elements of nitrogen, phosphorus, and potassium, has the largest amount of potassium absorption, and the absorption amount per mu is 23 kg. The seedling stage needs less potassium, which accounts for 21.2% of the total amount. The sprouting period of garlic sprouts is 53.2% and the garlic sprouting period is 25.6%.
The method of fertilization was from late March to early April, followed by the first pass of fertilizer, 28 kg per mu, and at the end of April, the second pass of topdressing garlic was applied at 22 kg per mu. The specific application method is to dissolve a certain weight of fertilizer into water and then flush it with water. Pay attention to the application of coated garlic and ground fertilizer so as to prevent the fertilizer from being insoluble in water on the top of the membrane, causing waste, not coating the garlic, spreading the fertilizer evenly on the surface, and then watering.
