2. Fertilizer and water management: Choose watering and topdressing in the morning on sunny days for 3 to 5 consecutive days, combined with watering acres of fertilization 20 kg + 15 kg nitrogen and potassium fertilizer. In case of special drought, you can water it once in late March. In principle, do not water too early, otherwise it will easily cause disease or secondary garlic growth. After each watering, it should be cultivated in time to raise the ground temperature to protect roots and seedlings. If the leaves have yellow tips before and after the Ching Ming Festival, a second top dressing should be carried out in time, mainly with quick-acting nitrogen fertilizer, and the usage amount per mu is 20 kg.
3. Prevention and control of diseases Garlic leaf blight and gray mold are common diseases. At the initial stage of the disease, small white dots appear on the tip of garlic leaves or light brown long oval spots appear on the surface of the leaves. When the disease is severe, the leaves die and the base rots. Strains fall down. Use 50% carbendazim 800 times liquid or 20% Fenmeining 2000 times liquid spray for prevention and treatment in time.
