Spring sowing leek in the Huang-Huai River Basin is from the first ten days of April to the middle of April, from December to February in the south and from May to June in the north, the ground temperature is stable above 12 ℃, and the daily average temperature is 15: 18 ℃. The use of strip sowing, dry seeds per mu of 6kg dry seeds, can plant 6000 square meters of vegetable land, immediately after sowing with plastic film, heat preservation and temperature, 70% of the seedlings when the top soil film uncover.

Seedling land arrangement

The leek seedling land should be easy to drain and irrigate. The sandy loam or clay soil where onion and garlic vegetables have not been planted in the past 1 or 2 years should be ploughed deeply before winter, poured with frozen water, and ploughed at the top of the next spring to preserve soil moisture. 40.5 cubic meters of rotten farm manure is applied per mu. In order to prevent leek maggots, 5% phoxim granules can be used per mu, 10 kg of dry soil and 15 kg of dry soil, evenly spread, fine rake after shallow ploughing, leveling for the border, 1.2-1.5 meters wide and 7-10 meters long, which is easy to manage.

Seed treatment

New seeds of leek can be sowed with dry seeds if the temperature is low in early spring. In order to sprout the seedlings, the seeds can be soaked and germinated, and the seeds can be dried for 1-2 days before seed treatment. 1-2 days before sowing, put the selected seeds in 40 ℃ warm water, stir hard, remove and scrub them clean, soak the seeds in 30 ℃ warm water for 8 hours, accelerate germination under the condition of 18-20 ℃, rinse with clean water twice a day, and sow seeds immediately when 60% of the radicles protrude.

Seedling stage management

The leek seedlings are about 5 cm high and lightly watered to loosen the soil in time. After 10 cm, it can be combined with watering to apply rotten manure or urea for 2 times, and crystal trichlorfon 0.5 kg per mu can be applied with water to kill leek maggots and other pests. Control irrigation after the seedling is 15 cm high to prevent overgrowth and lodging. Weeds should be pulled out in time, and the mu should be controlled with 0.5 kg 0.75 kg 25% herbicide ether when the seedling height is about 12 cm, or 0.15 kg 33% EC spray should be used to treat the surface before seedling emergence after sowing.

Rational planting

Leek planting selected soil fertile land convenient for drainage and irrigation, mu application of rotten farm manure 4-5 cubic meters, leveling the border. The border is 2-3 meters wide, with a group of 3 borders, with a 1-meter-wide cold belt on the north side. Transplant from late June to early July, cut off the end of the fibrous root before planting, and cut the bulbs into small handfuls. The row spacing is 13-20 cm, the hole spacing is 10-15 cm, and each hole is 6-8 plants. When planting, it is appropriate not to bury the leaf sheath, be steadfast after planting and water it in time.
