Management and Technical measures of Autumn garlic Seedling stage

First, the seedlings should be ploughed in time after emergence. The seedlings can be watered once after the seedlings come out, and the weeds can be ploughed and weeded. Before winter, compound fertilizer can be applied once in combination with watering, 150 kg per hectare. After watering, when the seedling grows the second leaf, the seedlings are cropped once in the middle tillage to promote the normal growth of the seedling root system. Second, pour enough overwintering water at the right time before the soil is frozen. After overwintering water irrigation, in order to ensure that the seedlings can survive the winter safely, firewood and grass can be covered on the border in the cold area north of the Yellow River to keep warm and prevent cold. Third, the weather turned warm the following year, and the overwintering garlic seedlings began to grow green. When the temperature is stable at 1 ℃ ~ 2 ℃, the covered firewood and grass should be removed. The removal of grass should be carried out in stages, first half, exposing garlic leaves, so that the seedlings gradually adapt to the external temperature and prevent sudden changes in temperature from freezing damage. After adaptation and exercise, the seedlings are completely removed from the covered firewood and grass. Fourth, the temperature is relatively low in early spring, so ploughing should be done immediately after the grass cover is removed to loosen the soil and raise the soil temperature. Fifth, after ploughing and drying for 3-5 days, pour back the green water. Combined with watering, compound fertilizer can be applied, which can be 225kg to 370kg per hectare. After the seedlings turn green, the leaves grow vigorously, so water and fertilizer should be applied frequently to promote the growth of seedlings.
