Temperature management. Leek likes to be cold, and its growth temperature is between 15 degrees Celsius and 24 degrees Celsius. It should be properly let out during the day. In order to promote germination, the room temperature should be maintained at 18°C~25°C during the day after the shed, and the room temperature should be controlled at 17°C~23°C during the day after germination. Before harvesting the first leek, the daytime temperature is 15°C~22°C, and the night temperature is 10°C~12°C. In the future, the temperature can be increased by 2 degrees Celsius to 3 degrees Celsius for each cut, but generally it should not exceed 30 degrees Celsius.
Fertilizer and water management. The growth of leeks requires lower air humidity and higher soil humidity. The air humidity in the greenhouse is maintained at 60% to 70%, and the absolute soil moisture content is maintained at 13% to 15%. Generally, those with heavy soils that have been watered in winter before the shed is no longer watered. In order to promote the growth of the next cut of leeks, you can pour a small amount of water 5-7 days before the first cut. 15kg to 20kg of ammonium nitrate per 667 square meters (mu) is hydrated and added with water, and then every cut of leeks is harvested. Water and fertilizer should be added for the first 5 to 7 days.
Fertilize the leaves. During the growth period, spray potassium dihydrogen phosphate once every 7 days at a concentration of 300 times the solution. When it grows to 15 cm, spray it with a dosage of 1 gram per mu, add 50 kg of water, and add 0.5% ammonium nitrate for better results.
