How to do intertillage and weeding for licorice? Practical methods and technical key points

Licorice is suitable for growing on idle beach and vacant land where crops cannot be planted, and such land tends to have many weeds as long as there is water, and the success or failure of planting and the level of yield are all related to weeding. When there are many weeds, the utilization rate of water and fertilizer by licorice is low, and the yield naturally decreases. For licorice fields planted in large fields, weeding should be carried out by combining manual weeding and chemical herbicide weeding. That is, in the year of planting, manual weeding is mainly used; starting from the second year, for plots with many weeds, select appropriate herbicides in June to July for chemical weeding, hoe and till once before the rainy season, and till once again after autumn. This time, attention should be paid to earthing up toward the roots so as to overwinter safely. In the second year, from regreening to the beginning of the dog days, carry out intertillage 1 to 2 times. After regreening in the third year, depending on the growth condition, intertillage may be carried out once or not carried out.
