Leek like cool climate and the temperature is low after autumn, so at this time we should strengthen management. First we should furrow, then fertilize cake fertilizer 50kg, farmyard manure 750kg, NPK 20kg, then cover the earth and water two times.
     After the Cold Dew, the temperature will be lower and the growth of leek will be slower, at this time we should stop watering and fertilizing, which can help leeks to accumulate nutrient.
After Frost's Descent, a windbreak with 13.-1.5cm’s height should be built to lower the temperature to make leeks dormant earlier.
    After the Beginning of Winter, we should cover things on them, and first we should clean all the weather leaves on them, then fertilize carbamide 15kg, then build a shed and cover thin film and grass carpet, and uncover the grass carpet 9 o’clock every morning and close it on 2 o’clock in afternoon, after 3-5 days, uncover the film, put earth on them.
