First, soak in warm water at 40°C for a day and night, then rinse in clean water, remove it and let it dry, then use it for sowing. Second, the fine soil preparation. It is best for growers to sow on open fields where no leeks have been planted. Apply enough 2,000 kg of organic fertilizer per acre before sowing, and then deep-dip, then sow the seeds of the buds into the ground. The depth of the soil is 1~ 1.5 cm is appropriate. Again, before the seed emerges, it is best to cover it with a straw to keep the soil moist to facilitate seed emergence. After about 10 days, the seedlings will emerge. After the emergence of soil still need to keep the soil moist, so when the root absorption capacity is weak, generally every 5 to 6 days, pouring a small amount of water, in order to protect the seedlings promote long.
Then when the leek seedlings grow to about 20 cm, they can be planted. According to the row spacing of 28 to 32 cm, 30 to 40 trees per ridge (2 m) are suitable, and the planting depth is about 10 cm. This will not only reduce the amount of seeding, but also extend the harvest time of leek, killing two birds with one stone.
