Key technical points and precautions for transplanting licorice
Generally, it is done in late autumn or early spring. In late autumn, before the land freezes; in early spring, around Qingming Festival, and no later than mid-April. The transplanting field should be prepared on the basis of autumn plowing from the previous year by making beds (bed width depends on a row spacing of 50 cm and how many rows are planted in the bed), then applying fertilizer. Dig up the seedlings grown the previous year after the ground at the field corners thaws, remove the aboveground parts and the lower growing points, and set them aside for use. In the prepared field, open furrows at a row spacing of 50 cm, 12 cm deep, then place the seedlings flat at the bottom of the furrow, with the heads placed obliquely toward the inner slope, at a slope of 10 degrees. When placing the seedlings, the heads of 2 rows should face each other. After the licorice emerges, it becomes wide-and-narrow row planting, with wide rows of 2 chi and narrow rows of 1 chi. This can achieve the goals of ventilation, light penetration, and high yield. After transplanting, the heads of the licorice seedlings should be 2 cun below the ground, and the small roots should be 3-3.5 cun below the ground. When transplanting, large and small seedlings should be planted separately, and the plant spacing should be 3-5 cun depending on the soil fertility.
Field management after transplanting: after licorice is transplanted, carry out one cultivation per year. Cultivation should be shallow, preferably 2-3 cm; too deep may damage the roots. After emergence, generally no watering is needed except during prolonged drought. Avoid long-term flooding to prevent root rot and seedling death, and strictly prevent standing water in the field. Drainage measures should be well implemented.
