Transplanting techniques of Glycyrrhiza uralensis

Generally, it takes place in late autumn and early spring, before the land is frozen in late autumn, before and after Ching Ming Festival in early spring, and no later than mid-April. On the basis of last year's autumn ploughing, the transplanting land should make a bed (the width of the border is determined by row spacing 50cm, depending on several rows of the border), and then fertilize, dig up the seedlings raised last year after thawing, and remove the aboveground and lower growing points for reserve. In the whole field, trench according to the row spacing 50cm, deep 12cm, and then put the seedlings flat on the bottom of the ditch, the head inclined to the inside slope, the slope is 10 degrees. The head of 2 rows of seedlings should be placed opposite each other, and licorice becomes a wide and narrow row after emergence, with a wide row of 2 feet and a narrow row of 1 foot, which can achieve the purpose of ventilation and light transmission and high yield. After transplanting, the head of licorice seedlings is 2 inches deep from the ground, and the fine roots are 3-3.5 inches from the ground. When transplanting, the seedlings should be divided into large and small seedlings, and the plant spacing depends on the soil fertility.

Field management after transplanting: licorice should be ploughed once a year after transplanting, with shallow ploughing, 2-3cm, too deep to avoid root injury, no watering except long-term drought after emergence, avoid long-term flooding to prevent rotting roots and dead seedlings, and strictly prevent stagnant water in the field, drainage measures should be taken.
