Garlic is sensitive to fertilizer and water, with a strong sense of fat, fat, distinct characteristics. Garlic root hair is small, and weak, poor absorption of root capacity. The nutrients needed for germination of garlic are provided by the seed petals, and as the seedling grows, the nutrients stored in the seed petals are gradually depleted, commonly known as . Fast-acting fertilizer should be applied at this time to ensure seedling growth and nurturing strong seedlings. After withdrawing from the mother’s full growth of soil nutrient supply.
