Time and method of fertilizing leeks

1. Nursery period

When leeks are planted, 8000-10000 kilograms of fermented stable manure and 40-60 kilograms of superphosphate are applied per acre of seedbed. The fertilizer is evenly spread on the surface of the soil and then plowed and flattened for border sowing. After the leek seeds emerge, combine with watering, apply thin human feces 2 to 3 times, and then transplant them in time. Fertilize leeks during the nursery period. Remember to apply water and fertilizer at the same time to avoid fertilizer damage.

2. Transplanting period

When transplanting leeks, the base fertilizer is generally 8000~10000 kg of fermented and mature manure per acre, 400~1000 kg of fermented and rotten cake powder fertilizer, 80-100 kg of superphosphate, 40-60 kg of potassium sulfate, and then plow the land. Rake flat, do border planting and planting. After planting, water the planting water immediately to avoid uneven use of base fertilizer, which may cause fertilizer damage and burn roots.

3. Growth period

Fertilization in the first year after planting: Water the leeks immediately after planting to ensure the survival of the seedlings. After the new leaves of leeks appear, 1,000 to 2,000 kilograms of human excrement or 15 to 20 kilograms of urea per acre is watered. Autumn is the most suitable season for leeks to grow. You should use 20 to 26 kilograms of ammonium sulfate per acre at intervals of 10 to 15 days, or use 2,000 to 4,000 kilograms of human urine and feces that are thoroughly fermented and decomposed.

4. Fertilize after the next year

In the spring of the second year, the leeks will turn green. After the new seedlings are unearthed, water 1000-2000 kg/mu of thin human excrement, or topdressing with 6-10 kg/mu of ammonium sulfate for fertilizer. When the leek seedlings grow 12 to 15 cm tall, 2,000 to 3,000 catties of human excrement are flushed with water per acre. When the leek seedlings are 15 to 18 cm high, water them once. Since then, every time leek is harvested, after the harvested wound has healed, new leaves must be fertilized and watered once. Remember not to topdress the wound immediately after harvest to avoid fertilizer damage. When top dressing leeks, you can use organic fertilizer and chemical fertilizer alternately. Use organic fertilizer and water to wash 2,000-3,000 kilograms of human excrement per acre, or use 18-20 kilograms of urea, or use 30-40 kilograms of ammonium sulfate.
