Temperature management The leek likes to be cold, and the suitable growth temperature is 15 ℃ ～ 24 ℃. It should be properly ventilated during the day. In order to promote germination, the room temperature should be kept at 18 ℃ ～ 25 ℃ during the day after buckling, and controlled at 17 ℃ ～ 23 ℃ during the day after germination. The temperature of the first knife leek before harvesting was 15 ℃ ～ 22 ℃ during the day and 10 ℃ ～ 12 ℃ at night. In the future, the temperature of each knife will increase by 2 ℃ ～ 3 ℃, but generally it should not exceed 30 ℃.
Fertilizer and water management Leek growth requires lower air humidity and higher soil humidity. The greenhouse air humidity is maintained at 60% to 70%, and the absolute soil water content is maintained at 13% to 15%. Generally, heavy winter soil is not watered if it has been watered before winter. In order to promote the growth of the next knife leek, a small amount of water can be poured 5 to 7 days before the first knife is harvested, and 15 to 20 kilograms of ammonium nitrate per mu should be hydrated to increase the amount of water. Watering and applying fertilizer.
During the foliar fertilization period, potassium dihydrogen phosphate is sprayed every 7 days at a concentration of 300 times; gibberellin can also be used at a concentration of about 40,000 times. When it grows to 15 cm, spray it, using 1 gram per mu, adding 50 kg of water, and then adding 0.5% ammonium nitrate for better effect.

Affected by climatic characteristics, the choice of corn varieties in Northeast China is to choose varieties with moderate maturity or early maturity, and at the same time have the characteristics of low temperature tolerance and high yield.
