Leeks are the most common vegetables in the countryside. If you just pick and eat at home, you can actually manage it. If you want to grow leeks in large areas for money, the correct fertilization method can make it grow better and faster. Let ’s take a look at the planting time and method of chives.
Leek fertilization time and method
Nursery stage
When leeks are planted, fermented and decomposed manure is applied at a rate of 8000 to 10,000 kg per acre of seedbed, and 40 to 60 kg of superphosphate. The fertilizer is evenly spread on the surface of the soil, and then levelled to make seeding. After leek seeds emerged, combined with watering, thin human urine and feces were applied 2 to 3 times, and transplanted at appropriate time. Fertilize the leek in the seedling stage, and remember to carry out water and fertilizer at the same time to avoid causing fertilizer damage.

2. Transplanting period
When leek is transplanted, the base fertilizer is generally 8,000 to 10,000 kg of fermented and rotten fertilized manure, 400 to 1,000 kg of fermented and rotten fermented cake powder, 80 to 100 kg of superphosphate, and 40 to 60 kg of potassium sulfate. Rake it flat and do the planting. Immediately after planting, water should be planted to avoid uneven use of the bottom fertilizer, which can cause root burns.
3. Growth period
Fertilization in the first year after planting: Leek is watered immediately after planting to ensure seedling survival. After the growth of new leaves of leek, 1000-2000 kg of diluted human feces or 15-20 kg of urea was applied per acre with watering. After the autumn is the most suitable season for leek, it should be separated every 10 to 15 days, using 20 to 26 kg of ammonium sulfate per acre, or 2000 to 4000 kg of urine and dung of thoroughly decomposed and thoroughly fermented humans.

4. Fertilize after leap year
In the spring of the next year, the leek returned to green, and after the new seedlings were unearthed, a thin layer of human feces was poured 1,000-2000 kg / mu, or 6-10 kg / mu of ammonium sulfate was added to flush the fertilizer. When the leek seedlings grow 12 to 15 centimeters high, 2000-3000 kg of human feces and urine are flushed with water per acre. When the leek seedlings are 15 to 18㎠tall, water them once. From now on, every time the leeks are harvested, after new leaves grow after the wounds heal, the fertilization and watering must be applied once. Remember to never topdress the wounds immediately after harvesting to avoid causing fattening. When leek topdressing, organic fertilizer and chemical fertilizer can be used alternately. Each time per acre, organic manure is used to flush human feces and urine with 2000 to 3000 kg, or urea is 18 to 20 kg, or ammonium sulfate is 30 to 40 kg.
